CHECK THAT THE INSTALLATION COMPLIES WITH THE SALAMANDER INSTRUCTIONS
IF PUMP IS STILL INOPERABLE, CONTACT OUR TECHNICAL ADVICE LINE ON 0191 516 2002
Fault
Probable cause
Recommended solution
Pump will not start
Insufficient gravity flow
Check suitability of pump – is installation in negative head
(see page 8)
Check inlet filters are not blocked
Check flow rate (min of 2l/min required on
both
hot and cold)
Inlet/outlet connections incorrect
Check that connections are plumbed the correct way round
and all valves are open
Electrical
Check power supply
Check fuse
Check circuit breaker
Debris under flow switch
Remove outlet hoses and check that flow switch sits in lowest
position
Float sticking in outlet
Ensure no debris is in outlet area
Flow switch malfunction
Contact Technical Advice Line
Reduced/ intermittent flow
Incorrect or no anti-aeration flange
fitted
Fit appropriate anti-aeration flange
Insufficient gravity flow
See above
Blocked inlet filters
Ensure that all filters and shower head are free from debris
Couplers restricting flow
Ensure that all AV couplers are straight and not bent or distorted
Air in system
Run system on full hot with pump switched off (i.e. gravity only)
for several minutes
Check cold water storage is correct for installation
Ensure cold water refill rate is adequate for installation Check
that vents are fitted as described in instructions
Wrong size pump for system
Ensure pump is sufficient to run the equipment
Hot temp set too high
Reduce cylinder stat setting to 60ºC max or fit HWS/TMV
Pump starts with all outlets
closed
Leak in system
Check for leaks
Outlet open
Ensure all outlets are fully closed or capped – i.e. no dead legs
in pipework
Pump is noisy
Air in system
See above
Pump vibrating on surface
Ensure rubber feet are fitted to pump
AV couplers causing vibration
Ensure that all AV couplers are straight and not bent or distorted
Pump is leaking
Pump exposed to mains water pressure Fit break cistern or remove from mains supply
Pump has suffered chemical damage Ensure that the pump has not come into contact with chemical
substance i.e. solder flux
Pump exposed to excessive
temperature
Is effective temp control fitted (cylinder stat or HWS/TMV valve)
Pump appears to have leaked but
not sure
Check leak is not from fitting in pipework above pump
