Fit pump inlet filters and vibration dampening feet.
It is CRITICAL to discharge water through the pump into a container using natural flow
before connecting the pump to outlet pipework in order to ensure the air has been
discharged from inlet pipework and pump chambers. This will not happen if the outlet
pipework is connected to the pump. The best method is:-
• Connect discharge pipework, not outlet pipes.
•
Check that all the AV coupler isolating valves are open.
• Fill system. Check for leaks.
•
DO NOT RUN PUMP DRY – to do so will cause irreparable damage to your pump and will
invalidate your warranty.
• Open shower mixer valve/system outlets to maximum hot and cold to check the natural
flow (unpumped) MUST be at least 1 litre in 30 seconds per side and 2 litres in 30 seconds
mixed for positive head pumps.
• Open hot water outlets fully for 5 to 6 seconds and then turn outlets off. Then open cold
water outlets fully for 5 to 6 seconds and turn outlets off. If flow is poor and inconsistent
repeat above steps until flow is steady.
• Repeat 2-3 times
The hot connection must be via an
approved side or top entry flange
