PRODUCT DESCRIPTION
Electric motor driven peripheral pump with bypass, complete with an automatic
control system consisting of flow switch and electronic control.
APPLICATION
The Mainsboost Flomate is a mains booster pump with an automatic control system for
domestic use, designed to assist the pressure from the mains supply, where the mains
pressure is insufficient. This unit requires a minimum unassisted supply flow of 0.6 l/
min to operate.
The pump is limited to producing a maximum flow of not greater than 12 l/min, and a
maximum pressure of 3.0 bar.
When the flow/pressure from the rising main exceeds the pump output, the patented
integral bypass will direct the water into the system as normal.
The Flomate mains booster is a patent granted design.
STORAGE
If this product is not to be installed immediately on receipt, ensure that it is stored in a
dry, frost and vibration free location in its original packaging.

1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION
A Water temperature
The water entering the pump must be controlled as follows:
1.11 The maximum allowable water temperature is 23 oC.
1.12 The minimum allowable water temperature is 4 oC.
B Pipework – General
1.13 Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump.
1.14 Flux: Solder joints must be completed and flux residues removed prior to
pump installation (flux damage will void any warranty).
1.15 Pipework design: Care should be taken in the design of pipework runs to
minimize the risk of air locks e.g. use drawn bends rather than 90obends.
1.16 DO NOT introduce solder flux to flexible hoses, pumps or pump parts.
1.17 DO NOT allow contact with oil or cellulose based paints, paint thinners
or strippers, acid based descalents or aggressive cleaning agents.

2.11 Access: For emergencies and maintenance the pump must be
easily accessible.
2.12 Protection: The pump must be located in a dry position, frost free
and protected from freezing. Ensure the pump is in a dry position,
away from heat sources, such as radiators and heaters.
2.13 Ventilation: Ensure an adequate air flow to cool the pump.
Separate the pump from other appliances that generate heat. An
80 mm air gap must be maintained to allow free air flow through
the fan cowl and over the motor at all times.
2.14 Safety: The motor casing can become very hot under normal
operating conditions. Care must be taken to ensure it cannot be
touched during operation.
2.15 Water retention: Site the pump in a location where in the unlikely
event of a water leak, any spillage is contained or routed to avoid
electrics or areas sensitive to water damage.
2.16 Location point: The pump must be located after the mains water stop cock,
in-line to the connection to the boiler. Do not site the pump in the roof
space, since air locks can easily result.
2.17 Pump position: The pump must be positioned on its anti-vibration mounting
feet and as close to the water source as possible.
2.18 Direction of flow: Ensure the water flow is in the direction of the arrow, as
marked on the flow switch reed clamp.

2.19 Pipework Connections:
Isolating valves: Always install isolating valves (not supplied) to
both suction and delivery pipe to aid future maintenance.
a) Incoming mains pressure can vary, but must never exceed 6 bar. If there is
a possibility of exceeding 6 bar, separate inlet pressure control must be
fitted.
b) To meet the requirements of the Water Supply (water fittings) Regulations,
a type EC – verifiable double check valve (not supplied) must be fitted.
c) It is advisable to fit a bypass pipe and isolating valves. This will allow
removal of the pump for maintenance and servicing, and ensure the water
supply into the property is still available during that period (Fig. 3).

7 TROUBLE SHOOTING GUIDE
Symptoms Probable Cause Recommended Action
Pump will not start. No water. Check required flow of liquid is available to the fittings of
approx. 0.6 l/min.
Water supply. Check water supply from mains and all stopcocks are open.
Electrical supply. Check wiring connections.
If flow exists inline with requirements – check that all
electric switches are on.
Is the correct fuse fitted?
Check circuit breaker is set.
Faulty reed switch/PCB Refer to circuit test as detailed in 7.11.
Internal motor thermotrip
activated.
Wait for thermotrip to auto reset and check that duty point
and run time is within specification (see Technical Section).
Pump starts when outlets
are off.
or
Pump cycles (hunts) on/off
frequently.
Leak in system Check tap washers, w/c valve washers, pipe joints.
Pump runs on when all terminal
outlets are closed.
Leak in system. Check tap washers, w/c valve washers, pipe joints.
Reed clamp out of position. Ensure reed clamp is fitted correctly in location groove
(Fig. 5).
Jammed flow switch. Remove flow switch reed clamp whilst pump is running. If
pump stops proceed to isolate the pump electrically and
hydraulically and remove brass housing that contains float.
Check for free movement.
Faulty reed switch or P.C.B. Remove flow switch reed clamp whilst pump is running.
If pump continues to run, this indicates a closed circuit in
either the flow switch reed or P.C.B. in the terminal box,
these should be checked electrically.

- 14 –
7.11 Flow Switch Circuit Test:
1. First confirm visually that the flow switch reed clamp has not been
dislodged during handling or installation. The clamp must be fully located
within its flow switch body groove as shown.
2. To carry out the following test you will need to obtain a magnet, a typical
fridge magnet is suitable.
3. Ensure the power supply is switched on.
4. Position the magnet directly in front of the reed clamp as shown. If pump
does not start, then slowly move the magnet up and down to a position
that exceeds the extent of the reed clamp. The pump should
instantaneously start at some point during this extent of movement.
If this does not happen, this indicates a possible fault with the reed
switch or the P.C.B which is located within the terminal box. These should
be checked electrically. Consult Stuart Turner for further instructions.
7.12 Environment Protection: Your appliance contains valuable materials which
can be recovered or recycled.
At the end of the products’ useful life, please leave it at an appropriate local
civic waste collection point.
