Se lect ion of i nsta llat ion si te
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.

9.4 Trouble Shooting
Users should contact with the professional maintenance staff when there is a
problem with the heat pump. Maintenance stuff may need to refer to the following
table for troubleshooting.
Malfunction Possible Problems Disposing Methods
Heat pump unit is
out of operation.
1. Power source fault.
2. Loose connection of
power wire.
3. Power fuse burnt out.
4. Low water level switch is
not on.
1. Cut off the power source
and check.
2. check the power wire
connection.
3. Check the fuse.
4. Supply water until the
water level switch is on.
Water pump is
running but no
water circulation or
much noise made by
water pump
1. Few water in the system.
2. Air exists in the water
system.
3. Some valves are not
opened.
4. The water filters is
blocked up.
1. Fill water into the water
supply system.
2. Discharge air from the
water system.
3. Open all the valves in the
system.
4. Clean the water filter.
Low heating
capacity.
1. Lack of refrigerant.
2. Bad water system heat
preservation.
3. Low evaporator heat
transferring.
4. Low water flow volume.
1. leakage hunting and fix it,
discharge all the refrigerant
and inject the right amount.
2. improve the heat
preservation.
3. Wash the evaporator.
4. Clean the water filter.
Heavy frosting, low
heating capacity.
1. The evaporator is too
dirty.
2. Defrost sensor fault.
3. The 4 way valve can not
change direction.
4. Over long defrosting
duration.
1. Wash the evaporator.
2. Change a new defrost
sensor.
3. Check the solenoid if it is
energized.
4. Change the temperature
for entering defrost and the
duration.
High noise of
compressor.
1. Liquid refrigerant into
the compressor.
2. Interior component of
the compressor is faulty.
1. Check if the thermostatic
expansion valve is faulty.
2. Change the compressor.
