13. Filling the system with glycol

When the solar heating system is lled with heat exchange liquid (Glycol), the heat transfer

medium displaces any air. The correct system charging will ensure that the solar system will run

without pressure losses and with high performance. However carefully you ll the system

manually, small bubbles of air might be caught in ‘air locks’ inside the pipes and some of these air

locks will be from air naturally dissolved in the water part of the glycol solution. Using the

automatic lling pump station design by RM Solar you will reduce the occurrence of air locks and

save time bleeding the system. (This is compatible with most solar systems).

Connecting the lling pump to the Double pump station:

13.1 Place the lling pump station on secure, horizontally clear place, close to the double

pump station so the hoses of 2 m can connect to the double pump station

13.2 Connect the hoses from lling pump station to the double pump station

13.3 The ow hose (5) connect on the part of the double pump station where the safety

relieve valve (A) is located

13.4 The return hose (6) connect to the valve below the solar pump next to

ow setter (B)

13.5 Fill the tray with glycol

13.6 Make sure the lling station switch is off and plug the pump into a convenient socket

13.7 Switch the lling pump station on and open the valves A and B - closing the grub

screw above the ow setter

13.8 Be prepared to carefully add additional glycol as needed to the tray

while it is operating

13.9 Leave to circulate for an hour
