InstallationUnit LocationRecommendations

Unit handling, LEFT or RIGHT for coil

connections, drain etc. is expressed

when facing the airflow thru the coil.

For dimensional details see the

standard submittals drawing, Figure 2

and 3.

When selecting and preparing the unit

operating location, consider the

following;

1. Consider the weight of the unit.

Appendix B has a complete listingof all component operating

weights.

2. Allow suff icient space for the

recommended clearances,

access panel removal, and

maintenance access. Refer to

Figure 8.

3. Coil piping and condensate drain

requirement must be considered.

Allow room for proper ductwork and

electrical connections. Support all

piping and ductwork independently

of unit to prevent excess noise and

vibration.

Duct Connections

All air ducts should be installed in

accordance with the standards of the

National Fire Protection Association for

the installation of Air Conditioning and

Ventilating System other than

Residence Type (NFPA 90A), and

Residence Type Warm Air Heating and

Air Conditioning Systems (90B).

lnlet and discharge air duct

connections to the unit should be

made with a flexible material

Installation

minimizing noise and vibration.

Typically, about three inches is needed

for this connection to rigid ductwork.

Ducts should be designed as a

function of the fan orientation. Duct

turns and transitions must be made

carefully to minimize air friction losses.

Avoid sharp turns and use splitters or

turning vanes when elbows are

necessary. Make turns in the same

direction of rotation as the fan.

Discharge ductwork should run in a

straight line, unchanged in size or

direction, for at least a distance of 1-1/

2-fan diameters (see Appendix C for

fan diameter).

Refer to Figure 9 and Figure 10 for

typical ductwork installation.

PipingCondensate DrainConnection

On cooling coil section(s) the drain pan

should always be connected directly

to a trap to ensure proper drainage of

condensate.

Caution: Failure to provide adequate

condensate piping may result in water

damage to the equipment or building.

lmportant: The applicable "rule of

thumb" for amount of condensate may

as high as 6 lbs/hr/ton for units serving

Coil Piping and Connection

General Coil Piping Recommendation

Refer to Figure 12 for typical cooling

and heating coil piping.

Proper installation, piping and trapping

is necessary to assure satisfactory

heating/cooling coil operation and to

prevent operational damage. Waterinlet and outlet connections protrude

through the coil section side panel.

Follow standard piping practices when

piping to the coil. Note the following:

Installation

areas with high latent heat.

Male-threaded, BSPT 1 1/2"

condensate drain connection is

provided on one side of the coil

section. The main drain lines and trap

must be the same size as the drain

connection.

Pitch the connection line horizontal or

downward toward an open drain and

install a plugged tee to facilitate

cleaning. Condensate lines should not

be connected to a closed drain. This

is to avoid the possibility of drawing

sewer gasses into the unit.

Drain traps must be primed. lf they are

not, the trap is essentially non-existent

and the drain pan will likely overflow.

Make sure the drain pan connection

openings are unobstructed. Trap the

drain line as shown in Figure 11 for

section with negative static pressure.

When more than one section has a

drain pan, trap each section

individually. Do not connect all drains

to a common drain line with only one

trap. Use the following drain

connection recommendations.

Figure 11

Drain Trap for Draw-Thru UnitsFigure 12

Typical Piping for Water Coil

AV - Automatic or

manual air vent

MV - Magnetic valve

GV - Gate valve

1. Support all piping independently of

the coils.

2. Provide swing joints or flexible

fittings in all connections that are

adjacent heating coils in order to

absorb thermal expansion and

contraction strains.

3. When attaching piping to the coil

header, make the connection only

tight enough to prevent leaks, the

maximum recommended torque is200ft-lbs.

4. Teflon tape or teflon piping

compound should not be used

because of its high lubricity, teflon

makes it easier to tighten the pipe

to the header joint past the point

where an effective seal is created,

thus damage to the coil could result.

5. "White Zinc" compound is

recommended, instead.

Caution: Use "Back-up Wrench" when

attaching piping to coils with copper

headers. Do not use brass fitttings or

brass pipe connectors. Brass distorts

easily and causes connection leaks.

Steam Coil PipingType A, AA Steam Coils

These are for central system,

industrial and process application with

one row, opposite-end connections.

Maximum standard operating limits:

Copper tubes: 100 psig and 400oF

Type AA coils feeds alternate tubes.

Refer to Figure 13 for typical steam coil

piping.

Caution: Condensate must flow freely

from coil at all times to prevent physical

coil damage from water hammer,

unequal thermal stresses, freeze-up

and/or corrosion.

Complete the following

recommendations to prevent coil

damage.

1. lnstall a 1/2 inch, 15 degree swing

check vacuum breaker in the

unused condensate return

tapping as close as possible to the

coil.

2. Vent the vacuum breaker line to the

atmosphere or connect it to the

return main at the discharge side of

the steam trap.

Note: Vacuum breaker relief is

mandatory when the coil is controlled

by a modulating steam supply or a two-

position (ON-OFF) automatic steam

supply valve.

3. Run the return pipe at the full size of

the steam trap connection except

for the short nipple screwed directly

into the coil condensate connection.

Do not bush or reduce the coil return

tapping size.4. Proper steam trap selection and

installation is necessary for

satisfactory coil performance and

service life. For installation, use the

following steps:

• Select trap based on maximum

possible condensate rate.

• Locate the steam trap discharge

at least 12 inches below the

condensate return tapping, this

provides sufficient hydrostatic

head pressure to overcome traplosses and assure complete

condensate removal.

• Float and thermostatic traps are

recommended because of gravity

drain and continuos discharge

operation.

• Use float and thermostatic traps

are recommended because of

gravity drain and continuos

discharge operation.

•

Use float and thermostatic trapswith atmospheric pressure gravity

condensate return, with automatic

control or where the possibility of

low-pressure supply steam exists.

• Use bucket traps ONLY when the

supply steams in unmodulated

and 25 psig or higher.

• Always install strainers as close

as possible to the inlet side of the

trap.

5.

6.

Caution: Always open the steam

supply control valve slowly to

prevent possible coil damage.

7.

8.

9.

10. Do not drain the steam mains or

take-off through the coils. Drain the

mains ahead of the coils through

a steam trap to the return line.

11. Overhead return require 1 psig of

pressure at the steam trap

discharge for each 2 - feet

elevation to assure continuouscondensate removal.

Do not modulate Type A, AA coils.

Use two position (ON-OFF) steamsupply controls.

Use a V-port modulating valve to

obtain gradual modulating action.

Do not modulate systems withoverhead or pressurized returns

unless the condensate is drained

by gravity to a receiver (vented to

the atmosphere) and returned to

the main by a condensate pump.

At start-up on units with fresh air

dampers, slowly turn the steam on

full at least 10 minutes before

opening the fresh air.

Pitch all supply and return steam

piping down minimum of 1-inchper 10 feet in the direction of flow.

Pulley and Belt

Proper installation techniques will

assure that you get full service life and

minimum down time from your belt

drives.

1. Turn machine OFF and lock out

power source.2. Remove belt guard, loosen motor

mounts and shorten center distance

between pulleys. Remove old belts.

3. lnspect. Repair or replace drives

components.

• Clean oil, grease and debris from

pulleys, remove rust with wire

brush.

• lnspect and replace damage

pulleys. Get your moneys worth

from a new set of belts by checkingand replacing worn or damaged

pulleys. ln the long run,

replacement pulley cost will more than

be recovered in increased belt life,

reduced downtime, and lower

maintenance expenses.

Check following:

a) Worn groove sidewalls, "Dishing"

should not exceed 1/32" for

individual belts. With a banded belt,

dishing should not exceed 1/64".

When a banded belt rides too low

in worn pulley grooves the tie bandcan be cut by the flanges between

the grooves.

b) Shiny pulley groove bottoms. This

is a sure sign that the belt has

bottomed out. The resulting

slippage shortens belt life.

c) Wobbling and/or damaged pulleys.

Generally caused by improper

pulley or bushing installation,

wobbling and/or damaged pulleys

can unbalance a drive, wear out

belt rapidly, and damage bearingsand bend shafts.

Check and repair worn bearings and

bent shafts.

4. Select replacement belts.

Replace all belts on a drive with a new

matched set from UNI-DRIVE.

a) Do not mix old and new belts on a

drive. A new belt will ride higher in

the pulley groove and operate at a

higher tension than an old belt.Running them together will

damaged the new belt as it cannot

carry its share of the load.

b) Do not mix belt from different make,

because dimensions and

constructions will vary running such

"Mis-Matched" belts will not give full

service life.

c) Replace with correct type and cross

section belt. Matched SPA section

belt with SPA section pulleys. Do notput a SPA belt section on a SPB

section pulley. Also dimensionally

similar belts can have very different

horsepower rating.

5. lnstall new belts

• Loosen the drive take up and place

the new belts on the pulley. Press

the belts with your hand to position

the slack of each belt on the same

side of the drive. lf the slack is ondifferent sides. start up loads can

break belt tensile cords.

• Do not pry or force belts onto the

pulleys. This can break the load

carrying tensile cords of the belt

and the belts will break or turn over

shortly after installation.

• Take up sleck until belts fit snugly.

6. Check pulley alignment.

• Place a straight edge or taut string

across pulleys faces to correctalignment.

• Check parallel position of shafts

and correct alignment or grooves.

• Note: Mount pulleys as close to

bearing as possible.

for proper torques. Fan sheaves

should be tight and aligned. See

Maintenance section for alignment.

2. Check the piping and valves for

leaks. Open and close the valves to

check for proper operation. Drainline should be open.

Caution: The use of untreated or

improperly treated water in unit coils

may cause scaling, erosion,

corrosion, algae, slime or other

equipment damage. Consult a

qualified water treatment specialist to

determine if water treatment is

required. The Trane Company

assumes no responsibility forequipment damage caused by

untreated or improperly treated water.

3. Check that the air filter is in place.

4. Remove all foreign material from the

drain pan. Check the drain pan.

Check the drain pan and

condensate line to make sure they

are not obstructed.

5. Close and secure all unit access

doors. Check that the latches aretight.

Delayed Start-Up

lf installation and start-up do not occur

immediately after delivery, take the

following precautions:

a) Protect equipment in an area not

exposed to excessive heat and

humidity.

b) Take special care to protectelectrical components.

c) Periodically, manually turn all

moving parts to avoid any possibility

of jamming or blocking.

d) For long stocking periods, remove

electrical equipment and store in a

dry atmosphere.

e) Verify the motor lubrication before

start-up and follow the motor

manufacturer recommendations.

f) lt should be noted that the bearings

are prelubricated. lt is howeverpossible that start-up will be noisy

until the grease is evenly

distributed.

Start-Up Procedures

After completing all items under

“preparation” the unit may be started.

The following checks and adjustments

should be made during initial start-up:

1. Bump-start unit and observe the fanwheel for proper rotation. As

indicated by indicated by rotation

arrow located on fan housing.

2. Measure the motor voltage and

amperage on all phases to ensure

proper operation The readings

should fall within the range given

on the motor nameplate. Never

overload the motor.

3. Maximum allowable voltage

imbalance is two percent. Voltageimbalance can cause motor

overheating and failure. Voltage

unbalance is calculated as follows:

The difference of the bracketed value

in the numerator of the equation are

absolute values. Disregard whether

they are positive or negative when

adding the values.

lf the fan speed is changed more than

5% from the original designed rpm, or

if parts such as shaft, fan wheels,

bearings, or other drive componentsare replaced, the unit vibration should

be checked. Do not exceed max. fan

RPM.

Pay particular attention to any vibration,

noise or overheating of the fan

bearings and motor (bearings may run

warm during break in)

Note: During break in period, bearing

temperature may be 1500

F and 1600

F.For normal running, bearing

temperature is 900F to 1000F.

Excessive Vibration-must be corrected

to prevent bearing and shaft damage.

The trouble shooting section details

the common causes for vibration.

Determining fan FPM - can be

determine by using a strobe-type

tachometer, or revolution counter.

Sheave Alignment

Align the fan and motor sheaves by

using a straight edge as shown in the

Figure 16.

The straightedge must be long

enough to span the distance between

the outside edges of the sheaves.

When the sheaves are aligned, the

straightedge will touch booth sheavesat points A through D.

Figure 16

Sheave Alignment

Fan Belt Tension/Alignment

Note: Fan belt tension should be

checked at least twice during the first

day of operation, since there is a rapid

decrease in tension until belts are run

in.

Proper belt tensioning is required to

ensure maximum bearing and drive

component life and is based on fan

brake horsepower requirement.

Belt Tension Measurement

Check the belt tension as follows:

Measure the span length of the drive

(in mm). With a belt tensioner at the

center of the span. apply a force K

(perpendicular to the span) large

enough to deflect the belt 15mm per 1

meter of span. Refer to figure 17.

DEFLECTION = SPAN X 15/1000mm

The deflection force for the belt should

be within the minimum and maximum

force shown in the Table A. When the

tension drops to the minimum value,

readjust to the maximum value.

To measure belt tension, use a belt

tensioner as shown in Figure 18.

Determine actual deflection by

depressing one belt with the belt

tensioner and measuring the

deflection relative to the other belts or

to belt line. Adjust the belt tension tothe correct force (Newton) and tighten

all setscrews to the proper torques.

and lubricated. Do not attempt to

lubricate bearings.

Fan Motors

lnspect periodically for excessive

vibration or temperature. Operating

conditions will vary the frequency of

inspection and lubrication. Contact the

motor manufacturer or Trane for

lubrication instruction. Most smaller

frame motors comes without oil tubes

or grease nipple where the bearingsare permanently sealed.

The motors with double shielded

bearings are lubricated for life and

cannot be relubricated.

W.E motors up to 132 frame and TECO

and Brook Hansen motors up to 180

frame comes with sealed for life

bearings, while motors above this

range, have open bearings with "flush

through" re-greasing facilities.

To re-lubricate the motor, complete the

following:

1.Turn the motor off. Make sure it

cannot accidentally restart.

2. Remove the relief plug and clean out

any hardened grease.

3. Add fresh grease through the fitting

with low pressure grease gun.

4. Run the motor for few minutes to

expel any excess grease through

the relief vent.

5. Stop the motor and replace the relief

plug.

Table1Motor Greasing lntervals

Standard condition: 8 hour operation

per day with rated or light loading in a

clean and low vibration environment.

Severe condition: 24 hour operation per

day with rated/light loading or in a dirty/

dusty environment or where the motor

is subject to vibration/light shock

loading.

Grease Type:

TECO/Brook Hansen motor - Use

Esso Unirex Lithium N3 grease.

W.E motor - Use Shell Alvania R3.

Coil Cleaning

Steam, hot water and chilled watercoils should be kept clean to maintain

maximum performance. lf fins become

dirty, clean with steam and detergent,

hot water spray and detergent, or one

of the commercially available chemical

coil cleaners. Rinse coils throughly

after cleaning.

Warning: Follow all directions provided

with chemical cleaners to avoid

personal injury and/or coil damage.Commercially available chemical

cleaners may contain caustic or

hazardous agents.

WARNING: DISCONNECT POWER

Trouble Analysis

Refrigerant coils should be kept clean

to maintain maximum performance. lf

fins become dirty, clean with cold water

and detergent or one of the

commercially available chemicals coil

cleaners. Rinse coils thoroughly after

cleaning.

Warning: Never use steam or hot water

to clean a refrigerant coil. Dangerous

pressures may be built up by improper

application of heat resulting in

equipment damage or personal injury.

Coil Winterization

Provisions must be made to drain

those

coils that are not in use when subjected

to freezing temperatures.

Caution: Failure to properly drain and

vent coils when not in use during

freezing temperatures may result in

coil freeze-up damage. Drain and vent

hardware provided by installing

contractor.

To drain these coils, blow out the coils

with compressed air, fill and drain the

tubes with full-strength ethylene glycol

several times, and then drain the coilas completely as possible.
