Maintenance By The Installer; Maintenance Of The Evaporator; Maintenance Of The Drain - Weider BWP 270 0A Mode D'emploi Et D'installation

MAINTENANCE BY THE INSTALLER:

• General check:
The installer has to check on smooth operating and the state of the installation (safety group, leakages, excess pressure
etc.).
• Maintenance of the anode
The state of the anode is either checked automatically (signal anode) or has to be checked manually at least once a year.
The checking interval is dependent on the local water composition. In extreme cases it might be necessary to check the
anode more often. Your installer should be perfectly aware of the local conditions to advise the best interval. To inspect
the anode, the front door must be removed. The anode is situated in the middle of the tank behind the front plate. It
must be replaced when the diameter is < 10 mm. The absolute minimum limit for the anode diameter is 6 mm. With < 6
mm anode diameter the additional catholic protection will not work (no manufacturer's warranty).

• Maintenance of the evaporator

Examine the evaporator, and if necessary remove dust and dirt, once or twice a year. To inspect the evaporator, remove
the air grating/duct connections. Dust particles can obstruct the air circulation, and this will reduce the HP performance
considerably. Clean the evaporator with water and a brush. Be careful and avoid damaging the fins of the evaporator
and keep the water away from the electrical parts

• Maintenance of the drain

The discharge pipe of the heat pump must be connected to a drain in accordance with the present regulations. The
defrost/condensed water outlet of the heat pump must always be kept free from dirt. How often this has to be done,
depends on the local conditions concerning dirt and temperature.
The user is responsible for checking and cleaning the drain water outlet/hose. This issue has also to be checked by the
installer during the maintenance service.
NOTE: A defective drain might cause multiple damages, such as defect electronic part, external corrosion, rotten
insulation. The manufacturer's warrantee does not cover these damages.
