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. 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. Installation instructions Check that the electrical rating shown on the shower matches the mains supply. A competent installer must undertake all installations. If in any doubt, advice and assistance should be sought from a qualified plumber and/or electrician. Installations and wiring must conform to current IEE regulations (UK) BS7671 WARNING! DO NOT INSTALL THIS SHOWER IN A ROOM WHERE IT MAY BE SUBJECT TO FREEZING We recommend that the installation be done in the following sequence. a) Fixing the shower to the wall b) Plumbing c) Electrical connections a) Fixing the shower to the wall 1. Position the riser rail at the height recommended in diagram 5 and mark its position. 2. Position the heater so the sides of the unit are vertical and the top is level with, or up to 0.6 metres (2ft) maximum below the top of the riser rail. Choose a flat piece of wall to avoid the possibility of distorting the back plate thus making the front cover a poor fit 3. Adjust the positions to get the most convenient arrangement taking the following into account. a) The possible need to use the handset over the sink for hair washing etc. b) The heater must not be mounted in the direct spray from the showerhead. Diagram 5 c) The handset must not be able to come into contact with any used water in the bath or basin. If it can, even after the hose has been retained by the hose retainer (see diagram 13), then a vacuum breaker must be fitted. It should be noted that these devices are liable to minor leakage so they must be positioned so that any drips are not detrimental. 4. Fix the riser rail with screws provided. The fixing holes at the base of the brackets will be disclosed by removing the plastic fronts. Assemble as shown in diagram 13. 5. Decide the position of the electrical cable inside the unit. If top or bottom entry is chosen (according to diagram 6), cut away the walls of the back-plate as shown in diagram 8. There is also the option to fit the cable from the rear in the channel provided. 6. Decide the cut away position of entry of the cold water pipe into the unit. Cut away the back-plate and front cover as shown in diagram 7 or 8. There is also the option to have rear entry (see later section on plumbing). 7. If you have not yet done so, remove the front cover (complete with control knob) of the unit by undoing the retaining screws at the top and bottom of the unit and lifting the cover off. The top-fixing hole is a keyhole slot, and should be marked and drilled first. Tighten top screw with head protruding about 10mm from wall and hook the back-plate over the screw head. This allows for correct and accurate alignment of your shower before marking and fixing the bottom/side position. You may not wish to tighten up all 3 other screws at this stage as the holes are elongated to allow for adjustment after other connections have taken place. 8. Do not obstruct the pressure relief device found in the back-plate slot underneath the outlet connection (see diagram 2). Especially if silicone sealant or similar materials are used around the edges of the back-plate. 9. There are a number of shields in the shower unit. These are important for the correct operation of this shower and MUST NOT be removed under any circumstances. b) Plumbing (see diagram 9) Diagram 7 Diagram 8 Diagram 6 The heater should be connected to the mains cold water supply. This must have a minimum running pressure of 100kPa, 1.0 bar (14.5 p.s.i) and a maximum pressure of 1000kPa, 10 bar (145 p.s.i). Before connecting the pipe-work to the shower ensure that pipe-work is flushed out. Diagram 9 Diagram 9 1. It is recommended that a WRAS (Water Regulations Advisory Scheme) listed isolating valve is fitted between the rising main and the unit. This will allow the unit to be serviced or exchanged without having to turn off the water at the mains stop valve. 2. The heater can be fed from a header tank provided this has a minimum head height of 10.5 metres (35ft). 3. 15mm copper or stainless steel pipe should be used alongside with a standard compression fitting. In multiple shower installations correct pipe-work sizes should be calculated to maintain adequate flow to each shower. 4. a) If top entry is chosen, turn the elbow 180° into the required position and fit a standard 15mm in-line compression fitting. There is a removable side section, which will aid you with this (diag.7). b) If rear entry is chosen, turn the elbow 180° and treat it as top entry except ...
