4.5 Components
Compressor
The dependable high efficiency
compressor, with optimized R410A
system, can achieve high water
temperature up to 60 degrees Celsius;
while ensures long life of the compressor.
4-Way ValveThe reliable 4 way valve can
avoid gas mixing, and ensure
stable defrosting.
Condenser
The Tube-in-shell heat exchanger as
condenser, with bigger heat
exchanging area and higher
efficiency.
Evaporator
The hydrophilic fin-tube heat
exchanger has big heat exchanging
area and rational fin distance, thus
significantly improves heating and
defrosting efficiency.
ABS Plastic Fan
The exterior motor fan, with multiple fan
blades, is strictly balanced. The multiple
fan blades run slower, and make sure
high air volume, thus largely brings down
the noise.

5.4. Wire Controller Installation
The wired controller is originally fixed on the maintenance door of the machine; please refer to below steps if you want to install it on the wall:?1.Take down the controller from the machine. The communication wire is connected with the circuit board, separate them from where they match.
?2.Use a screwdriver to open the clip as picture 1, separate the controller as 2 parts, as picture 2.
?3.On the wall that you are going to install the controller, drill 2 holes at a level parallel to the sight line as picture 3. The hole distance is 60mm, diameter is 8mm.
?4.Place the plastic screws of the enclosure into the hole, and use the tapping screw (ST4*16 D-1) enclosed to fix the back cover of controller on the wall, as picture 4.
?5.Match the front and back covers perfectly, as picture 5, make sure that it is fixed firmly on the wall.
?6.Connect the communication wire well.

9.5 Parameter Number and Description Table.
The manometer is a kind of high pressure equipment, when the heat pump is on, the manometer pointer 2would point to the pressure value of refrigerant, the max. value of protection is 42kg/Cm . When the heat
°pump is off, the pointer would point to the same value as actual ambient temperature (e.g. 28 C) and related 2air pressure (e.g.18kg/ Cm ).
Please check the manometer when you restart the heat pump after not using for a long time, if it shows ° °ambient temperature valve is smaller than 2 C (When the ambient temp. is higher than 2 C), it means that
refrigerant has leaked a lot, and you need to confirm with professional engineer as soon as possible.
