Particle Fi Lter; Checking The Protective Anode - IVT Greenline HT Plus C Assembly, Commissioning And Maintenance Manual

Maintenance
Particle fi lter
The task of a particle fi lter is to ensure no particles or dirt enter the
heat exchangers. Over time the fi lter can become clogged and will need
cleaning. There are particle fi lters on both the "hot" and "cold" sides. To
clean the particle fi lters:
1. Shut down the heat pump using the ON/OFF button.
2. Close the valve and unscrew the sealing cap.
3. Loosen the circlip holding the screen in the valve. Use the supplied
circlip pliers.
4. Lift out the screen from the valve and wash clean with water.
5. Refi t the screen, the circlip and sealing cap.
6. Open the valve and start the heat pump using the ON/OFF button.

Checking the protective anode

Only applies to heat pumps with integrated, stainless hot water cylinder.
A protective anode is located in the top of the cylinder with the task of
preventing corrosion. The hot water cylinder must be fi lled with water in
order for the anode to work.
A lamp, inside the front cover, indicates the anode status. If green, the
protective anode is operating and working normally. Red can indicate a
fault. When large amounts of hot water are used (e.g. with a bath) the lamp
may show red for a short period without there being a fault. However, if
the light is on for more than ten hours this indicates the anode is faulty and
you should contact your dealer. If the fault occurs at the weekend you can
wait to the next working day before contacting your dealer.

Note
On the "cold side" the particle fi lter
is located outside of the heat pump. It
may be concealed by insulation mate-
rial or a black box.
On Greenline HT Plus E the "hot
side's" particle fi lter is fi tted in the
heatpump. On Greenline HT Plus C it
is located outside of the heat pump.
