HOW TO INSTALL YOUR POWERSTREAM WARNING: ALL WIRING AND INSTALLATION MUST BE SUPERVISED BY A SUITABLY QUALIFIED PERSON. WARNING: DO NOT INSTALL WHERE IT MAY BE SUBJECTED TO FREEZING CONDITIONS.
Deciding the wiring route You have a choice of whether to feed the electric cable through the side or through the back of the unit. If it going through the side of the unit, cut out the plastic lug to expose the grommet (diagram 2). If is going through the back of the unit, cut through the grommet on the backplate with a sharp knife (Take Care!). Make sure you do not remove the grommet from the backplate (diagram 3). Feed the cable through the grommet before you fix the unit to the wall.
WARNING: ENSURE THAT THE MAINS WATER SUPPLY MEETS THE REQUIREMENTS LISTED ON PAGE 3 BEFORE CONTINUING WITH INSTALLATION. WARNING: BEFORE CONNECTING THE PIPE WORK TO THE POWERSTREAM, ENSURE THAT THE PIPE WORK IS FULLY FLUSHED OUT. Fitting the pipes The unit should be connected directly to the main cold water supply. We recommend that you use Ø15mm copper or stainless steel pipe for the inlet and outlet connections. (See addendum sheet for local installation requirements).
MAKING THE ELECTRICAL CONNECTIONS WARNING: THIS WATER HEATER MUST BE EARTHED. The electrical installation must be in accordance with the current BS.7671 (IEE Wiring Regulations) and “Part P” of the Building Regulations and/or local regulations Wiring to the mains (Check the unit rating to see which applies) Rating Fuse/MCB Isolating Switch Cable Size 9.5 kW 40 amps 40 amps 6 mm² / 10 mm² * 10.8 kW 45 amps 45 amps 10 mm² 12.
COMMISSIONING YOUR POWERSTREAM CHECKING FOR LEAKS Let the water run through the unit for a few seconds. Close the outlet and check that no pipe joints leak. ADJUSTING THE SERVICE VALVE If the unit is to supply a basin, - turn on the hot water tap fully at the basin. - turn the service valve on slowly until the neon illuminates on the product (max temperature). - adjust the service valve until the water comes out of the tap at the required temperature.
HOW TO USE YOUR POWERSTREAM WARNING: DO NOT USE THE UNIT IF YOU THINK IT MAY BE FROZEN, AS THIS COULD RESULT IN SERIOUS DAMAGE TO THE UNIT. WAIT UNTIL YOU ARE SURE THAT IT HAS COMPLETELY THAWED OUT BEFORE YOU SWITCH ON. Basin Check that the power is switched on at the mains isolator switch. Turn on the hot water tap FULLY. If you do not turn the tap on, you will find that the temperature of the water will vary. The hot water temperature will have been set using the service valve (diagram 5).
WHAT TO DO IF THINGS GO WRONG (1) SELF HELP If the unit is not working satisfactorily, make the following checks before calling out the installer. Any one of these adjustments could restore the performance. Symptom Cause What to do Little or no water flow. The main water supply is turned off. Cold water only - neon light off. Water too cold - neon light on. The main water supply is not turned on enough. The water flow rate is too high. Turn on the main supply fully at the stop valve.
WHAT TO DO IF THINGS GO WRONG (2) PROFESSIONAL SERVICE If the previous “Self Help” checks fail to restore the performance, you should seek professional help. The person who installed the shower is probably the best one to investigate and correct it and is certainly the person to contact if you have had a problem in the guarantee period. The following additional checklist is provided for the benefit of the qualified service person.
HOW YOUR POWERSTREAM WORKS Water comes in through the inlet, via a flow switch. The flow switch measures how much water is passing through the unit. If it detects more than the preset level of:2.7 litres/minute for the 9.5kW model and 3.3 litres/minute for the 10.8kW and 12.0kW models The units heating elements are switched on. This is shown by the neon light glowing. The water is heated instantly as it passes through the copper heat exchanger tube.
