2.Installation
A. Heat pump installation location and attentions
*. Heat pump is not allowed to be installed in the place where combustible gas
may leaks.
*. Heat pump is not allowed to be installed in the place where there is oil or
corrosion gas released.
*. Heat pump should be installed in a open space, and good ventilating.
*. Heat pump each side to wall or barrel should be keep certain distance, air
outlet to barrel distance should ≥2m, air inlet distance to wall or barrel≥0.5m,
bottom distance to ground ≥0.5m, other side distance should be enough for
installation or repairing.
*. Heat pump should be installed on concrete basic or steel bracket, and
anti-shock pad should be put between heat pump and basic or bracket. Then use
expansion bolt to fix heat pump on bracket.
* Water drainage pipe and ditch should be set around heat pump and water pipes
and water tank. When testing or repairing, maybe need drain plenty of water, and
when heat pump is working, there are some condensed water flow down.
B. Installation diagram ( it is only for reference,the actual installation shall be
based on actual project)

* for hot water and floor heating
*for heating/cooling

P6
Tips for installation related to the water pipe part:
*Install a valve at the highest point of each water circulations for releasing air
from water system.
* A Y filter is very important in front of circulating water pump of heat pump.
* If more heat pumps installed in one water pipe system, the connection of these
heat pumps can’t be in series, only can be in parallel or independent.
C. Pre-start up
1.Checking before pre-start up
* Check if the water pipe are connected well and if there is any leakage. The
water supply valve are open.
* Make sure the water flow is enough and meet the demand of the heat pump
selected and water flow smoothly without air . In cold area, pls make sure that
the water flow is without freezing
* Check if the power cable is connected well and properly grounded.
* Check if fan blade is blocked by the fixing plate of fan blade and fan blade
protecting grill.
* Check if the tank has been filled with water or enough water volume that can
meet the demand of heat pump running
Pre-start up
After check completely and confirm no problem for installation, the unit can be
power to start up .
After connect power supply, heat pump delay 3 mins to start. Check carefully
is there is some abnormal noise or vibration or if the working current is normal
or if water temp increasing is normal.
After the unit is working properly for 10 minutes without any problem, then the
pre-start up is usefully completed. If not, pls refer to Service and Maintenance
Chapter to solve the problem.

The two series mainly used to supply hot water and heating house, have two
working mode: Hot water mode and hot water + heating mode.
2.1 Hot water mode controlling, the unit start and stop based on the hot water tank
temp. and the setting temp.
2.2 Hot water + heating mode controlling
2.2.1 Hot water mode: working same as 2.1
