Fault
Probable cause
Recommended solution
Pump will not
start
Insufficient gravity flow
Check that installation complies with Salamander instructions
Check suitability of pump – is installation in negative head
(see page 7)
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 service
Reduced/
intermittent flow
Incorrect or no
anti-aeration flange fitted
Check that installation complies with Salamander instructions
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 (ie gravity only)
for several minutes
Check cold water storage is correct for installation and pump is
fitted to Salamander instructions
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 65% max or fit HWS/TMV
Pump starts with
all outlets closed

Check for leaks
Outlet open
Ensure all outlets are fully closed or capped - ie no dead legs
in pipework
Pump is noisy
Air in system
See above
Pump vibrating on surface
Ensure rubber feet are fitted to pump

Ensure that all AV couplers are straight and not bent or distorted
Pump is leaking
Pump exposed to mains
water pressure
Check that installation complies with Salamander instructions
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
