1.The electrical installation must be in accordance with current BS. 7671 (I.E.E. regulations).

2.The unit should be connected into a switched 3 amp double pole fused spur, with a minimum contact gap of 3mm in each pole.

The switch must be fitted outside the bathroom.

Alternatively, a double pole ceiling switch, with a pull cord and a minimum contact gap of 3mm in each pole could be used inside the bathroom.

For additional safety, it is recommended that a residual current device be used with either of the above switches.

3.The earth continuity conductor of the electrical installation MUST BE effectively connected electrically to all exposed parts of the appliances and services in the room in which the water heater is to be installed in conformity with the current BS. 7671 (I.E.E. wiring regulations).

WARNING : THIS APPLIANCE MUST BE EARTHED.

4.We recommend using 1.0mm2 Twin and Earth cable for this application. Connect the mains cable in to the terminal block, ensuring that all power is switched off before connecting to the mains supply.

Recommended order : -

a)Strip back wire approximately 6.0mm.

b)Ensure wires are secure in the correct terminal block holes.

c)Ensure that the mains cable is securely clamped in the cable clamp provided on the backplate.

FINAL INSTALLATION PROCEDURE AND COMMISSIONING

WARNING : DO NOT switch on the electricity supply until the following procedure has been completed. Failure to do so could cause the pump to run dry and invalidate the guarantee.

1.Fit the shower hose to the outlet of the shower unit. Do not connect the handset at this stage. Ensure that the water isolating valves are fully open and that the hose is directed to waste.

2.The shower unit is factory set in the commissioning mode. A commissioning link is connected to the p.c.b. (see diagram 2), which opens the solenoid without switching on the motor. This allows water to flow through the pump, thus ensuring that all air is removed.

The cover is not required to be fitted at this stage but be aware of live parts when the electricity is temporarily switched on.

3.Switch on electrical supply. After a few moments water should drip from the hose.

It may be necessary to hang the hose from the shower unit whilst priming especially if the head of the water is minimal. This will speed up the priming process.

When water drips through the hose at a constant rate. Stop flow of water by switching off the electrical supply.

Ensure electricity is switched off. Remove p.c.b. commissioning link. Replace with the connector attached to the front cover start/stop/flow control switch.

Store commissioning link in a safe place for future use.

4.Ensure side section is in place (see diagram 2). Refit cover using 3 fixing screws. Attach handset to shower hose.

5.A temperature limiter is provided so that the maximum working temperature can be set. The limiter is factory set but can be adjusted depending on incoming water conditions.

The limiter is visible when Temperature Control Knob 'B' is removed (see diagram 14).
