Bleeding and filling system with coolant
It is easiest to fill ducting starting from the lowest point of installation. If you start filling from the header tank there
will be airlocks. Filling from the lowest point takes most of the air out from the system, so this makes bleeding much
easier. If there is air in the ducting heater does not work correctly.
Premix enough coolant according to manufacturers instructions ( Standard recommendation is 30% antifreeze, 70%
water in Finland)
Install T-branch to the lowest point of coolant ducting
Hose installation instructions
1. Open Expansion Tank
2. Over Bleeding Hose
3. Vacuum Pump
4. Pump
5. Pliers A
6. Pliers B
7. Valve
8. Coolant Feeding Tank
Coolant system needs to bleed from air
before starting the heater. Never use
heater without coolant.
Have hose closing pliers ready for feeding the coolant.
1. Connect the vacuum pump to the expansion tank’s over bleeding hose.
2. Check that Valve 7 is open.
3. Squeeze the hose with the pliers B to prevent the coolant from flowing from this direction.
4. Gently pump the vacuum pump a couple of times. Listen when the coolant begins to flow to the heater.
5. Continue to pump the vacuum pump a couple of pumpings at the time as long as you see the coolant in the
expansion tank.
Note! Too high under pressure / vacuum (too many pumpings at the time) may cause
deforming of the heat exchanger.
6. When you see that the coolant is in the expansion tank, close the pliers A. Then open pliers B.
7. Keep on pumping the vacuum pump until you can see that no bubbles are coming from the line to the expansion
tank.
8. Close the valve (7) in the feeding tank.
9. Open the pliers A.
10. Remove the vacuum pump and make sure the coolant surface does not drop too low in the expansion tank.
Coolant expands 5% when the temperature changes 60 °C.
If you have more than 50 liter coolant in the system, you will need higher volume expansion tank or
buffer tank
(standard expansion tank volume is 3 liters).
Example table for coolant expansion
Coolant volume (20 °C) Coolant volume (80 °C) Standard expansion tank utilization
10 l 10,5 l 16,7 % ( 0,5 l / 3 l )
50 l 52,5 l 83,3 % ( 2,5 l / 3 l )
