PRODUCT DESCRIPTION
Electric motor driven peripheral pump with bypass, complete with an automatic control
system consisting of flow switch and electronic control.
APPLICATION
The 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
applied for integral bypass will direct the water into the system as normal.
The Flomate mains booster is a patent granted design.
Please note the following warning signs.

1 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 35 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.
1.18 Water flow: An un-assisted flow rate of at least 0.6 l/min is required
through the outlets to be pumped in order to make this pump work.
C. Plumbing & Electrical Installation Regulations
1.19 The plumbing installation must comply with “The Water Supply (Water Fittings)
Regulations 1999” and “BS 6700” building regulations.

2 LOCATION - GENERAL
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.

- 7 -
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) 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).

7.11 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.
