Professional Service/Self Help Check Lists - Redring Selectronic Premier Handbook

Connect the mains water supply to the Inlet of the shower via 15mm copper, stainless steel or plastic
pipe using a 15mm compression fitting. See (Diagram 4) for advice on Rear Entry fitting.
The Inlet fitting is designed to rotate through 180° to allow for either Top or Bottom/Rear entry fitting
(See Diagrams 3).
Installation Note: The inlet fitting is designed to enter a compression fitting only. DO NOT use push
Fit connectors as full engagement cannot be guaranteed. DO NOT use excessive force when making
these connections.
Installation Note: If installing a water feed pipe from the back, the use of a soldered Elbow
Connector is recommended. It should be positioned approximately 87mm from the inlet connector
centre. The centre of the inlet connector to the wall surface is 21mm.

If these 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.

PROFESSIONAL SERVICE CHECK LIST
This additional checklist is provided for the benefit of the qualified service representative.
WARNING! Switch Off The Electricity At The Isolator Before Removing The Front Cover To
Make Checks.
a) Poor temperature control.
I
b) Water too COLD
I
c) Poor or no control over water flow.
I
d) No water when START/STOP button is
pressed.
I
e) Unit has been switched OFF using
START/STOP button but can be heard
heating the water.
I
f) Pressure relief valve operated.
Press the cooler button.
Clean spray plate holes on showerhead.
I
Press the warmer button (See Page 9 For allowed
adjustment range) .
I
Clean spray plate. Select Outer/Inner only.
I
Switch OFF electricity at ceiling/wall isolating switch,
wait a few seconds, switch on again.
(Note: The shower should be switched OFF each
time after use at the ceiling/wall isolating switch.
I
Note: If there is no water flowing then the shower will
automatically switch OFF after about 5 seconds.
I
Check the water supply is turned ON.
I
Unit in over temperature mode see section on "purging".
I
Check ceiling/wall isolating switch is ON.
Check power is ON.
I
Temperature range may be limited by Temp/Lock setting
setting (See Page 9)
I
This is normal.
There is a motor inside the shower used to adjust the
flow and this always operates at the start of each shower.
Check inlet/outlet thermistors to see if they are in circuit.
Check for blockage in the inlet filter.
I
Check circuit through thermal cut-out.
Check circuit through all 4 elements.
Test should be done using a low voltage resistance
meter whilst the power is switched OFF at the isolating
switch.
Check working voltage.
I
Replace inlet valve assembly.
I
Check water supply. Check circuit through solenoid coil.
If OK replace logic PCB.
I
Replace triac PCB.
I
Check for cause of high pressure and remove it.
Replace pressure relief valve. (Not covered under
Guarantee).
