7 1 Preparation
After finish the installation tasks, please check the items:
-
1 Check the SW4 1 dip switch setting to ensure the correct voltage
- :
SW4 1
Single phase:
2 cable
Check if the power cable is connected correctly, and check if the screws have been screwed down.
Please use specified
3 Water circuit
Check if the water pipes are correctly connected, and the pipe dimensions are correct.
Heatproof measures must be taken for water outlet pipes and water inlet.
Check if all the shut off valve and manual valve is opened, check if all the joint is fastened.
Before connecting the heating water system to the heat pump, he heating system must be flushed to
remove any impurities, esidue from sealants, etc. Any accumulation of deposits in the iquifier could cause
the heat pump to completely break down.
O
nce the heating system has been in talled, it must be filled, de erated and pressure tested.
C
onsideration must be given to the following when filling the sys em:
Untreated filling water and make-up water must be of drinking water quality (colourless, clear, free from
sediments)
Filling water and make-up water must be pre-filtered (poresize max. 5µm).
.
4 Water Quality Requirements
The water should not contain any substances that could form deposits. The limit values for iron (<0.2mg/l)
and manganese (<0.1mg/l) must be adhered to prevent iron ochre sedimentation in the heat pump
system.The use of surface water or water containing salt is not permissible. Your local water utility can
provide you with general information regarding the possible use of ground water. Water analyses
are carried out by specially-equipped laboratories. It is not necessary to carry out a water analysis with
regard to evaporator corrosion if the annual mean temperature of the ground water does not exceed 13°C).
In this case, the limit values for iron and manganese must be adhered to (iron ochre sedimentation).

7 2 Water filling
Before fill the water to heat pump water system
,
connected correctly
Two method of water filling
please open the tap water valve, open ball valve
10, air discharge valve 15 and water tank air discharge valve, until the water is full. Then close air discharge
valve15 , ball valve 10 and water tank air discharge valve.
