Specifications

CPE100TF, CBM100SS, CBM130SS and CBM250SS

These units are set up as a BOOSTER pumps by utilising an air chamber with a pressure

regulator to provide a constant pressure at the outlet. All models are provided with

non-return valves and Model CPE100TF is also provided with an inlet filter.

The pumps will automatically cut in when the water pressure reduces to 2.0 Bar,

and cut out when the pressure reaches 3.5 Bar. (These pressures are 3.5 and 5.2

bar respectively for Model CBM250SS). These pressures are factory set and must

not be altered. The pump may continue to operate for a short while, after the tap

is turned off, until the cut-out pressure is reached.

In order for the system to operate correctly, it is necessary to pressurise the air

chamber to 1.5 Bar (22psi), which is carried out as follows:

Unscrew the large protection cap on the end of the air chamber to reveal the air

valve, and use an air line or foot pump to charge the chamber to the specified

pressure, checking with a standard air pressure gauge until satisfied. Remember

to replace the protection cap when completed.

IMPORTANT: This procedure MUST be carried out BEFORE connecting to the water supply.

PRIMING

When suction lift is used to draw water into the pump it is essential that all

connections and hoses are completely air tight, otherwise the system will not work.

Although the pump is a ‘self priming’ type, it is nevertheless necessary to completely

fill the inlet side of the pump with water before being started for the first time, or if

the system has been drained for maintenance or repair purposes. This is known as

priming the pump and is carried out as follows :-

1. Locate and remove the small filler plug, situated on the top of the pump

chamber, and slowly fill the pump with water until all air is expelled.

NOTE: If a filter is fitted to your pump it is recommended that you remove the

brass plug on top of the unit, and fill the bowl with water.

In the case of the CPE100P, no filler plug is provided, and the pump body is

therefore filled through the outlet port before its’ connection

2. Adjust any device which may be fitted to the outlet side of the pump, so as to

ensure as great a flow as possible.

3. Switch on the pump and check for leaks. Water should start to flow through

the system after a short while. If, after 2-3 minutes, depending upon the suction

depth, water does not flow, check to ensure:

a) The inlet pipe is completely secure and completely free from defects.

Even a pin hole could prevent the pump from drawing water. This is the

most common problem encountered when operating water pumps.

b) The pump body has been primed correctly, and is completely filled with water.

NOTE: If the pump is gravity or pressure fed, priming will not be necessary, as

the pressure of water will purge the system of air.
