FOR THE USER
Expansion vessel
A plastic expansion vessel is connected to the heat pump heat transfer
circuit (cold side). The level in the vessel should not fall below the
minimum level 1/3. If the fl uid level is too low, contact your dealer. After
discussions with your dealer fi lling can take place as set out below:
The heat pump
must
be in operation all the time while fi lling.
1. Remove the cover on the valve on top of tank. Now carefully open the
valve (fi gure 1).
2. Check that the valve is fully open (fi gure 2).
3. Fill with anti-freeze or water (to 2/3) with the help of a clean watering
can or the like (fi gure 3).
4. Close the valve and fi nish by screwing on the cover (fi gure 4).
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.
On the cold side the particle fi lter
is located outside of the heat pump.
It may be concealed by insulation
material or a black box.
On Greenline HT E Plus the hot
side’s particle fi lter is fi tted inside the
heat pump. On Greenline HT Plus C
it is located outside of the heat pump.
