HOW YOUR POWERSTREAM WORKS

The Power stream instantaneous water heater is designed to provide instant hot water at a fixed heating capacity. By opening the water outlet, tap or shower the appliance flow switch activates and in turn energizes the heating element. The neon light on the front of the appliance is illuminated whenever heating is on.

As the water is instantly heated with a fixed power capacity, the appliance output temperature varies depending on:

• The temperature of the mains water supply.
•  The water flow rate, i.e. volume of water through the unit.
• The power consumption of the unit.

The temperature of the main water supply can vary from 5°C in winter up to about 20°C in summer, with an average of about 12°C. The charts below show the water temperature (°C) you can expect from the unit, operating at 9.5/10.8/12.0kW for the different flow rates (inlitres/minute).

Recommended Temperature °C
min| max| min| max|
32| 40|  36| 40
Recommended Flow Rate (I/min)
min| max| min| max| __
3.0|  7.0| 5.0| 7.0

This means that with the 12.0kW unit you can shower at 39°C with a flow rate of 5 litres/minute in the middle of winter. The Power stream appliance is intended to supply up to two wash hand basins or one wash hand basin and one shower application. It cannot deliver the temperature and flowrate combination required to fill a bathtub.

This appliance must NOT be used for commercial applications or applications where high temperatures at high flow rates are required, i.e. dishwashing or for filling baths.

The unit includes a dual thermal cut-out (diagram 1) which is attached to the heat exchanger tube. It will switch off the heater elements if the water flow is reduced too much and the temperature goes above a set limit.

The first stage cut-out is cyclic and will automatically reset as the water temperature falls. The unit will then function normally again.

The second stage cut-out when triggered needs to be reset manually inside the unit. This cut-out will only operate in exceptional circumstances or if the product is being used outside of its scope of suitable uses. (diagram 1)

The unit can supply two outlets – for example, a shower and a basin, or up to two basins – but water from the unit will be shared between the outlets. This is particularly important if a unit supplies a shower and a basin, as the basin should not be used while someone is using the shower. The unit is NOT to be fitted to a bath or kitchen sink other than for hand-washing purposes.

HOW TO INSTALL YOUR POWERSTREAM

THIS APPLIANCE MUST BE INSTALLED, INNITIALLY COMMISSIONED AND SERVICED BY A QUALIFIED PERSON IN ACCORDANCE WITH THE NATIONAL AND LOCAL REGULATIONS IN FORCE IN THE COUNTRY OF INSTALLATION.

 DO NOT INSTALL WHERE IT MAY BE SUBJECTED TO FREEZING CONDITIONS.

Diagram 2a
Examples of fitted units

Diagram 2b
Acceptable unit orientation

The Power stream is recommended to supply a MAXIMUM of two washbasins (see diagram 2a) OR a washbasin and shower (see diagram 5b).

If the Power stream is connected to a mixer tap, then only NON- Thermostatic types should be used (water mixes at the outlet pipe only).

The Power stream is NOT to be fitted to a bath or kitchen sink other than for hand-washing purposes. (See product flow rate tables on page 3).

BEFORE YOU START

For mains electrical connection and associated information please refer to page 7 of this booklet. Check the pressure of the main water supply, 1 bar – 6 bar. The appliance must not be directly connected to a water supply greater than 6bar. If mains pressure is greater than 6 bar please refer to page 5.

To operate correctly, the unit requires the following – 1-6bar and 3-4L/min.

FIXING THE UNIT TO THE WALL

Deciding the position

• If being used in a public place, position the unit out of reach to discourage vandalism.

• Fit the unit onto a flat piece of wall, well away from any potential splashes of water or spray.

• Position the unit either upright or lengthways (diagram 2a/b), whichever is most convenient for plumbing and wiring, keeping the hot water pipe length to a minimum (less than 3m is recommended) and insulate the pipe in order to save energy.

• If the unit is to supply a basin, you can fit it either above or below the basin.
  Wiring Lug Removal
  Diagram 3 – Lug Removal
  

• Follow steps A-D in Diagram 3 above to remove plastic lug.

• Feed cable through rubber gland in metalwork.

Fixing to the wall

• Undo the retaining nuts and take the front cover off the unit. Hold the backplate in position against the wall whilst you mark the four fixing holes.
• Drill the holes and fix the unit to the wall using the screws supplied.
  Diagram 4 – Back Plate
  

Hydraulic Connections

IF A NON-RETURN VALVE IS FITTED AND/OR THE INLET FEED TO THE UNIT IS GREATER THAN 6BAR, THEN THE INSTALLATION MUST ALSO INCLUDE A 3.5 BAR PRESSURE REDUCING VALVE AND A 6 BAR PRESSURE RELIEF (EXPANSION) VALVE AS SHOWN IN DIAGRAM 5a.

ENSURE THAT THE MAINS WATER SUPPLY MEETS THE REQUIREMENTS LISTED ON PAGE 4 BEFORE CONTINUING WITH INSTALLATION.

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. A gauze filter should be incorporated to prevent any debris entering the venturi.
• For the inlet and outlet connections Ø15mm copper or stainless-steel pipe must be used. Plastic pipe of any kind cannot be used.
• Use PTFE tape for making screw joints. Do not use a jointing compound as it can enter the unit and cause damage to the flow switch mechanism.
• Remember to keep the hot water pipe runs as short as possible (Ideally less than 3m) and insulate this piping especially on longer runs.
• If the unit is to supply more than one basin outlet, the height should be the same at each outlet if they are to be used at the same time. If not, one outlet will take all the water. In some cases, it may be worth fitting a second unit.
• When the pipework has been plumbed in, flush it through with water before you connect the unit, to remove any swarf or loose particles.

Connecting the unit to the pipes

• The inlet and outlet are clearly marked on the unit. All models have Ø15mm straight shank connections.
• The unit comes with a service valve (diagram 6) which must be fitted on the inlet of the unit. The valve can be used to turn off the water supply to the unit if it needs servicing, or to reduce the main supply flow if it is too high (see “commissioning” section on page 8).

Fitting the attachments

• f the unit is to supply a shower, you will also need a “Redring Mixer Unit”. Available in chrome finish and suitable for surface or concealed pipe entry (see page 9 for details). Only the approved shower mixer unit (300001357) is guaranteed to operate with this product.
• If the unit is to supply a shower, and the shower handset can reach water in a bath or basin, you must fit a vacuum breaker to comply with Water By-laws. Alternatively, use the hose-retaining feature built into the soap dish. Because water can sometimes seep through, you should position thevacuumbreaker where dripping will not do any damage.
• If the unit is to supply a basin or two basins, we recommend that you use “¼ turn lever control spray taps” (see page 13).

MAKING THE ELECTRICAL CONNECTIONS

THIS WATER HEATER MUST BE EARTHED.

The electrical installation must be made by a competent person in accordance with the current BS.7671 (IET 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).

• For cable runs over 10 meters or where cable is not flat clipped and surface mounted, the larger size is the minimum required, as per BS.7671.

A means of local isolation and protection to the appliance is recommended i.e. 50A fused spur.

A 50A RCBO circuit breaker with 30mA sensitivity must be fitted at the local consumer unit on the same supply, or as BS.7671

If the unit is fitted in a Bathroom:

.5 kW and 10.8 kW Powerstream: A standard 45 Amp cord operated isolator switch is recommended. 12.0 kW Powerstream: A double pole 50 Amp isolator switch is required. This must be mounted out of reach of the shower cubicle or bath.

Wiring the Powerstream

• he unit has been designed to accept up to 16mm² supply cable. 6mm² & 10mm² cable can be used as required. In all cases the outer sheath of the cable MUST project through the grommet (diagram 7). This will prevent water getting into the unit.
• Strip back the insulation on the LIVE (brown or red), NEUTRAL (blue or black) & EARTH (green/yellow or green) mains wires about 8mm.
• Feed the cable through the entry grommet.
• Connect the cables to the terminal block (diagram 7).
• Make sure that the live, neutral & earth terminal block screws are tightened securely (1N/m minimum).
• Fit the front cover and tighten the retaining screws.

  Failure to comply with these instructions could result in failure of the terminal block.

Ensuring the earth continuity

• If the unit is fitted in a bathroom, to conform with the current BS.7671 (formally IET regulations), the units earth continuity conductor must be effectively connected to ALL exposed metal parts of ALL other appliances in the room. The pipe work must be bonded.

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. Allowing for the temperature of the water to settle after each adjustment.
  • Check that the unit works correctly when the basin tap is closed and then opened again: if not, adjust the service valve slightly.
• If the unit is to supply a shower
  • Turn the hot water tap on the mixer unit fully on.
  • Turn the service valve clockwise until the neon light goes out, then turn it back until the neon just comes on.
  • Check the water temperature at the handset and, if necessary, turn the cold tap on and adjust to get the desired shower temperature.

YOU MUST REGULARLY INSPECT THE SHOWER HOSE FOR WEAR AND DAMAGE. REPLACE IF NECESSARY.

TO MAINTAIN THE PERFORMANCE OF YOUR SHOWER, YOU MUST DESCALE THE SHOWER HANDSET REGULARLY.

All water contains particles of lime-scale, which build up in the shower handset and unit reducing the performance. It is therefore important to clean the shower handset by simply rubbing the rubber nozzles or soaking in proprietary lime-scale remover and rinsing thoroughly before use. The frequency of this will depend on water hardness and experience.

The hot water tap should be turned fully on, at all times i.e. every use , so
that the unit will operate correctly. Restricting the flow may cause the unit
to cut out.

The water heater must be mounted on a vertical wall or surface and positioned with water connections as shown in Diagram 2b.

The unit should be connected directly to the main cold water supply and not to pre- heated water. The unit should be installed with service valves on the inlet.
These valves can be used to turn off the water supply to the unit if it needs
servicing, or to reduce the water flow if it is too high.

HOW TO USE YOUR POWERSTREAM

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 YOUSWITCHON.

Basin

• Check that the power is switched on at the mains isolator switch.

• Turn on the hot water tap FULLY at all times. If you do not turn the tap on fully, you will find that the temperature of the water will vary. The hot water temperature will have been set using the service valve (diagram 6).

• If the unit has been used recently, run the water through for a few seconds to let the temperature stabilize, we advise you DO NOT touch the water flow during this time.
  Y OU MAY INITIALLY GET A SHORT BURST OF VERY HOT WATER FROM THE UNIT IMMEDIATELY UPON OPENING THE TAP.

• If a second tap connected to the unit is also turned on, the hot water will be shared between the two and so the flow will drop.

Shower

• Heck that the power is switched on at the mains local isolator switch.

• Turn on the hot (or “flow”) tap FULLY (diagram 9).

• If the unit has been used recently, run the water through for a few seconds to let the temperature stabilize, we advise you DO NOT enter the water flow during this time.
  YOU MAY INITIALLY GET A SHORT BURST OF VERY HOT WATER FROM THE UNIT IMMEDIATELY UPON OPENING THE TAP.

• Turn on the cold (or “temperature”) tap, if necessary, to adjust the temperature of the water.

• Make sure that no other outlets connected to the unit are used whilst you are in the shower, or the water flow will drop suddenly.

• It is important to clean the shower spray plate regularly.

• In order for the Power stream to function correctly, only the “Redring Mixer Kit” can be used. The kit, Cat No. 300001357, comes complete with full accessories including a 3 position multi-function shower handset.
