This guide assumes the use of an RM Solar Filling Pump, no other methods are supported by RM

Solar as they can often lead to excess air in the system.

Prior To Filling The System

Cover the panels 30 minutes before lling the system, and leave covered whilst lling. (If it is not

possible to cover the panels, ll the system when there is little solar energy, e.g. early morning, late

evening.

Ensure the expansion vessel pressure has been set correctly at 2.5 bar.

Connecting The Filling Pump

At the Pump Station:

1. Connect the right hand hose (Side with the pressure gauge) of the pumping station to the top

lling pump connection of the lling pump.

2. Connect the left hand hose of the lling pump to the bottom lling connection on the solar

pumping station.

3. Twist the red and blue temperature gauges on the solar pump station 45

clockwise.

4. Close the grub screw (twist all the way in) on the solar pump station, this is between the pump

and the ow gauge.

5. Open the buttery valves on the pump station where the lling pump hoses are connected,

manually open any zone valves ect on the solar primary pipe work.

At the Filling Pump:

1. Open the right hand isolation valve, close the left hand isolation valve and open the isolation

valve beneath the white tank.

2. Fill the white tank at least half full.

Running The Filling Pump

1. Switch on the lling pump - keep the tank topped up to half full.

2. The pressure can be adjusted using the ll pressure regulator on the lling pump.

Whilst Filling:

1. Whilst lling open the bleed screw on the solar circulating pump, expel all the air and then re-

close.

2. Allow the lling pump to circulate for approximately 1 hour.

3. Check in the lling tank that no air bubbles are returning with the glycol.

4. Close the isolating valve on the solar pump station beneath the circulating pump.

5. Allow the system to pressurise to between 3-4 bar.

6. Close the isolation valve beneath the pressure gauge beneath the pressure gauge on the solar

pump station.

7. Switch off the lling pump and close the isolation valves.

8. Remove and drain the hoses from the solar pump station.
