If the unit is not secure or not installed, it may cause damage. The minimum support weight
required for installation is 21g/mm2.
If the unit was installed in a closed area or limited space, please consider the size of room and
ventilation to prevent suffocation caused by refrigerant leakage.
Use a specific wire and fasten it to terminal block so that the connection will prevent pressure
from being applied to parts.
Wrong wiring will cause fire.
Please connect power wire accurately according to wiring diagram on the manual to avoid burnout of
the unit or fire.
Be sure to use correct material during installing.
Wrong parts or wrong materials may result in fire, electric shock, or falling of the unit.
Install on the ground safely, please read installation instructions.
Improper installation may result in fire, electric shock, falling of the unit, or water leaking.
Use professional tools for doing electrical work.
If power supply capacity is insufficient or circuit is not completed, it may cause fire or electric shock.
The unit must have grounding device.
If power supply does not have grounding device, be sure not to connect the unit.
The unit should be only removed and repaired by professional technician.
Improper movement or maintenance of the unit may cause water leakage, electric shock, or fire.
Please find a professional technician to do.
Don't unplug or plug power during operation.It may cause fire or electric shock.
Don't touch or operate the unit when your hands are wet. It may cause fire or electric shock.
Don't place heaters or other electrical appliances near the power wire.It may cause fire or

3
electric shock.
The water must not be poured directly from the unit. Do not let water to permeate into the
electrical components.
4. ⚠Warning
Do not install the unit in a location where there may be flammable gas.
If there is flammable gas around the unit, it will cause explosion.
According to the instruction to carry out drainage system and pipeline work. If drainage system or
pipeline is defective, water leakage will occur. And it should be disposed immediately to prevent
other household products from getting wet and damage.
Do not clean the unit while power is on. Turn off power before cleaning the unit. If not it
may result in injury from a high-speed fan or electric shock.
Stop operating the unit once there is a problem or an fault code.
Please turn off power and stop running the unit. Otherwise it may cause electric shock or fire.
Be careful when the unit is not packed or not installed.
Pay attention to sharp edges and fins of heat exchanger.
After installation or repair, please confirm refrigerant is not leaking.
If refrigerant is not enough, the unit will not work properly.
The installation of external unit must be flat and firm.
Avoid abnormal vibration and noise.
Don’t put your fingers into fan and evaporator.
High speed running fan will result in serious injury.
This device is not designed for people who is physically or mentally weak (including
children) and who does not have experience and knowledge of heating and cooling
system. Unless it is used under direction and supervision of professional technician, or

III. Installation Instructions
WARNING: Installation must be carried out by a qualified engineer.

15
This section is provided for information purpose only and must be checked and adapted if
necessary according to actual installation condition.
1. Pre-Requirements
Needed equipment for installation of heat pump:
Suitable power supply cable for unit’s power.
A by-pass kit and an assembly of PVC tube, stripper, PVC adhesive and sandpaper.
A set of wall plug and expansion screw.
We recommend to use flexible PVC pipe in order to reduce transmission of vibration.
Suitable fastening studs may be used to raise unit.
2. Location
Please comply with the following rules about heat pump location choosing.
1. The unit’s location must be convenient for operation and maintenance in the future.
2. It must be installed and fixed on flat concrete floor. The floor is stable to support the weight of the
unit.
3. A water drainage device must be provided close to the unit in order to protect the area where it is
installed.
4. If necessary, mounting pads could be used to support the weight of unit.
5. Confirm the unit is under well-ventilated condition; air outlet port is not facing to the windows of
nearby buildings and the outlet air can not be returned. In addition, provide enough space around the
unit for repair and maintenance.
6. The unit must not be installed in an area exposed to oil, flammable gases, corrosive products,
sulphurous compounds or close to high frequency equipment.
7. To prevent mud splashes, do not install the unit near road or track.
8. To avoid noise to neighbours, please make sure the unit is installed in less noise sensitivity area
or good sound isolation area.
9. Keep the unit as far as possible away from children.
10. Installation space
Unit: mm

16
Anything could not be placed within at least 1m in front of heat pump.
Leave at least 500mm of empty space around the sides and rear of heat pump.
Do not put any stuff on or in front of heat pump!
3. Installation Layout
The heat pump is connected to a filtration circuit with a by-pass valve. The by-pass valve should be
half-opened (throttled), while all the other valves should be completely opened. We suggest to half
open by-pass valve to avoid excessive pressure on heat pump.
It is imperative that by-pass is placed after water pump and filtration. By-pass path usually consists of
3 valves. That makes it possible to adjust water flow which passes through heat pump and isolates
heat pump completely from any maintenance without affecting flow of filtration cycle.
The filter must be cleaned regularly to ensure that water in the system is clean and avoid blocking of
filter. It is necessary that drainage valve is fixed on the lower water pipe. If the unit is not running
during winter months, please disconnect power supply and let out drain water from unit through
drainage valve. If ambient temperature of running unit is below 0℃, please keep water pump
running.
