Note: 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-shape filter is very important in front of circulating water pump of heat pump.
●
If more pieces heat pump installed in one water pipe system, the connection of these heat pumps can’t
be in series, only can be in parallel or independent.
Pre-start up
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
If everything above is ok, the unit can start up , if any of them fails, please improve it
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 3mins 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, please refer to Service and Maintenance Chapter to solve the problem.
2.9 MINIMUM CAPACITY OF THE WATER SYSTEM
For the household air conditioning water system, in order to obtain good thermal stability, the air
conditioning load should be accurately determined first, and the host with matching installed capacity
should be selected; Secondly, the greater the water capacity of the system, the greater the system
cooling capacity, the better the thermal stability of the system. Conversely, the thermal stability of the
system is worse. Therefore, when designing the water system, it should be checked whether the water
capacity of the calculation system meets the thermal stability requirements of the system. When the
actual water capacity of the system cannot meet the requirements, the system main pipe diameter or a
new water storage tank should be increased. The system minimum water capacity can refer to the
following recommended values:
