Commissioning & Troubleshooting
Commissioning – All Pumps
• Turn on the water supplies and allow system to fill -
DO NOT SWITCH ON ELECTRICITY
IMPORTANT:
All NewTeam pumps utilise quality ceramic water seals. To prevent damage it is
essential that water is allowed to flow through both pump chambers to purge
out any airpockets prior to the unit being switched on.
1. Turn on mixer valve, and allow the water to flow through hose without the fitted
handset under gravity flow in full hot and cold positions for approximately one
minute to ensure no foreign matter is left in pipes and the system is purged of air.
2. At this point we recommend checking the inlet filters for debris, which should
be cleaned if required, thus ensuring the best long term performance from
the shower.
NOTE: Remember to isolate the water supply before removing the hoses to
check the filters.
3. Switch on electricity supply to pump.
4. Turn on mixer valve (pump should start) and operate at full flow for a further minute
or until all remaining air is purged from the system.
NOTE: For negative head installation, operate the starting switch for long
enough for air to purge from flow switches.
5. Turn off mixer valve and attach handset to hose. The commissioning procedure is
now complete.
NOTE: All of the Pumps apart from Singlespeed incorporate a variable speed
control, which should be set to suit the users requirements and to achieve
optimum performance through the handset. Turn the control anti-clockwise to
increase and clockwise to decrease the output. Do not use excessive force. We
recommend the pump runs at the minimum speed necessary to give satisfactory
performance (normally 10-12 litres of water per minute). Running the pump at
too high an output can waste hot water and increase noise from the pump motor.

Troubleshooting

In the event that the system will not operate follow this procedure:
• Is the pump switched on?
• Check all fuses and electricity supply.
• Is water supply reaching pump? Check isolating valves are turned on.
Check cold water storage tank has not run dry.
• Shower runs cold. Check that there is sufficient hot water in the cylinder.
• Check inlet and outlet pipework is connected correctly.
• Motor may have overheated. Switch off mains and allow the pump to cool and it
will auto re-set. Check for adequate ventilation around pump.
• Is handset and all pipework 230mm (9 inches) below the level of water in the cold
water storage tank? If not, a negative head kit will be required. See page 8.
• Remove the inlet adaptor couplings to the pump and flush out any debris from
the integral filters, remembering to isolate the water supplies. If system will
still not run, contact NewTeam Customer Service Department (01536) 264012.
