General
Your Shower Pump has been carefully designed, manufactured and tested in England.
The
important instructions MUST
be followed, otherwise the pump may be damaged and
your warranty invalidated.
Please dispose of any packaging supplied with this pump in an environmentally
friendly and legal manner.
Important Instructions
•
Do not connect the pump directly to the water mains supply.
A shower pump installation requires a cold water storage tank and a hot water cylinder.
The pump cannot be used with combination boilers.
•
Full bore isolation valves must be fitted in the inlet and outlet pipe work to the
pump.
•
When unpacking and installing the pump, ensure that
no foreign particles
(such as
solder, dust, etc) are allowed to enter the pump. These will cause the flow switch to
malfunction and damage the pump impeller.
•
The pump supply head must comply with the minimum and maximum shown in
the technical data sheet. See figure 1, page 6 for installation diagram.
The pump cannot operate if the level of the water in the cold water storage tank is
below the level of the pump.
•
Do not fit non-return valves in the inlet line to the pump.
The pump must be able to
vent back to the supply tank.
•
The strainers supplied with the pump must be used on inlet connections.
•
The pump requires dedicated hot and cold water supplies.
•
The hot water supply to the pump inlet should be connected from the first outlet from the
hot water cylinder expansion pipe. Use of a Surrey Flange is recommended for optimum
pump performance.
•
No solder flux.
Do not allow
any
solder flux to come into contact with any of the plastic parts of the
pump or hoses. If this happens, clean immediately with strong detergent, rinse and
inspect surfaces for corrosion.
•
Do not let the pump run dry.
Purge with water thoroughly for 5 minutes on cold water and 5 minutes on hot water
before
running pump. Then check that each connection is water tight and not leaking.
•
Complete all pipe work before making electrical connections. Do not let any water
into the electrical terminal box.
•
After completing installation, the whole system must be thoroughly tested – operating
both hot and cold at full flow.
Maximum hot water temperature must not exceed 60°C (140°F) in accordance with
BS6700 2006.
Finally check that each connection is watertight and not leaking.
