Diagram 9

5. It is permissible to use a WRAS (Water Regulations Advisory Scheme) approved sealant

sparingly whilst avoiding excess finding its way into shower operating parts.

6. With the isolating valve connected, flush the pipe-work through to remove any particles etc

before making the final connection to the shower. Blockage in the waterways (particularly the

handset and solenoid valve) will prevent the heater working properly.

7. The shower is designed to have an open outlet and should only be used with manufacturer

recommended fittings. Do not connect the handset until after the shower removable side

section and front cover are fitted.

WARNING! DO NOT FIT A TAP ON THE SHOWER OUTLET.

TAKE CARE TO AVOID RESTRICTING THE OUTLET AND FLOW

FROM THE HANDSET OR THE PRESSURE RELIEF DEVICE.

c) Electrical Connections

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

and “Part P” of the Building Regulations and/or local regulations.

1. The shower is designed for a single-phase A.C. electrical supply.

Please check the rating plate on the unit to see what details apply.

Remember to uprate the cable if it runs in thermal insulation in a loft, or for a longer distance.

2. A means for disconnection in all poles must be incorporated in the fixed wiring in accordance

with the wiring rules. We recommend ceiling switches.

3. WARNING! This appliance must be earthed.

4. Cut back cable as in diagram 9.

Connect cable to terminal block making sure that ALL the retaining

screws are VERY tight and that no cable insulation is trapped in the

block.

WARNING!

FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD

RESULT IN A FAILURE OF THE TERMINAL BLOCK AND CABLING.

5. Fit the front cover into position making sure the knob is aligned

correctly with the flow valve (see diagram 11).

6. Fit the front cover into position making sure the knob is aligned

correctly with the flow valve (see diagram 11).

WARNING! TAKE CARE WHEN REPLACING THE FRONT COVER

TO AVOID DAMAGING ANY COMPONENTS.

What to do if things go wrong

SELF HELP

If the shower is not working satisfactorily, make the following checks before calling out the

installer. Any of these adjustments could restore the performance

a) Water too HOT Increase water flow by adjusting the temperature control clockwise.

Clean spray plate holes.

Select outer or combination spray patterns (620 only).

Switch power to MEDIUM setting.

Increase pressure of water supply e.g. fully open service valve or stop cock.

Check hose is not kinked restricting the water flow.

b) Water too COLD Decrease water flow by adjusting the temperature control anti-clockwise.

Select inner or outer spray patterns only (620 only).

Switch power to FULL setting.

c) Spray pattern

poor

Clean spray plate and flush heater.

Select inner / outer spray pattern (620 only).

d) Water goes cold

while using

shower

Check water pressure has not fallen so far as to let pressure switch cut out,

e.g. another tap drawing water off.

Raise position of handset.

e) Broken parts Please contact our spares department on 0844 372 7750.

Fitting instructions are provided with spares.

PROFESSIONAL SERVICE

If the previous checks fail to restore the performance, you should seek professional help.

The person who installed the shower is probably the best one to repair it and is certainly

the person to contact if you have a problem in the guarantee period.

The following additional checklist is provided for the benefit of the qualified service person.

WARNING!

SWITCH OFF THE ELECTRICITY AT THE ISOLATING SWITCH

BEFORE REMOVING THE COVER TO MAKE CHECKS.

a) Water too HOT

Water flow restricted by blockage in filter of solenoid valve.

Switch off water and undo plastic nut on elbow, loosen brass nut to swing

elbow away from solenoid.

Remove filter in solenoid with long nosed pliers and flush clean.

b) Water too COLD Check circuit through thermal cut-out

Check circuit through microswitch on the pressure switch

Check each element circuit.

Check tightness of electrical connections.

c) Water leaks from

burst pressure

relief valve

Check for cause of high pressure and

remove it.

i.e. Blockage on outlet or blocked spray plate.

Replace the pressure relief disc (not covered by guarantee).

d) Water does not

flow when Knob

“A” is rotated

(when button

“C” is pressed -

620 only)

Check the circuit through the solenoid coil.

Check circuit through mini microswitch (push switch – 620 only)

Possible timer PCB fault (620 only). If defective, then replace.

Power supply not reaching shower.
