4.5 Components
Compressor
The dependable high efficiency
compressor, with optimized
R410a system, can achieve high
water temperature up to 60DegC,
while ensures long life of the
compressor.
4-Way valve
The 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.
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.
Photo Features/AdvantagesComponents
Circulation pump
Famous German brand WILO
circulation water pump used.
The main components are of famous brands and with good quality tested.
For example: Panasonic compressor, R410A gas, high efficiency tube-in-shell heat exchanger etc.
Also, components can be replaced by customer’s own requirement.

5. Installation
5.1 Heat Pump Installation
10
Selection of installation site
1. Installation must be simple and allow easy access for later work.
2. If the unit is to be installed on the floor, its undercarriage should be heightened, to avoid
ingression of acculated water in rainy season. In snowy areas, it is important to prevent
accumulated snow from blocking up the air-out.The recommended height is 20cm to 30cm.
3. Drain ditch or other facilities should be arranged under the outdoor unit, to avoid the
environment influence because of water discharge.
4. To install the unit at balcon or top of building, the installation site must meet the
Allowable bearing capacity of building structure, without affecting the structural safety.
5. Ensure the unit is well ventilated, direction of air exhaust is kept away from windows of
neighboring buildings, and the exhaust air cannot flow back. Moreover, adequate service
clearance should be kept around the unit.
6. The unit sould not be installed at places accompanied with oil, Inflammable gas, corrosive
compents, e.g. Sulfur compound, or high-frequency equipment.
7. The unit must be installed on reliable base or framework. Weight capacity of framework
should be 3 times of the body weight, and safeguard measures should be taken to avoid
malfunction of fastenings.
8. The unit should not be installed at sites with typhoon/earthquake hazards. Midair
installation should be avoided as much as possible as machine falling down may result in
Severe accident.
9. Do not install the heat pump close to a road or path to avoid mud splashing on the unit.
10. Keep, wherever possible, the unit out of reach of children.

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. Please pay attention that 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.
