IMPORTANT NOTICE

• For your satisfaction and safety, read all instructions before installing or using this instant hot water

heater.

• This particular unit is not intended for commercial use.

• This appliance should be connected to mains water feed.

• This water heater may not be suitable for unsupervised use by children, the elderly, or persons of

deminished responsability due to the risk of scalding should the ﬂow of water not be controlled

properly.

• Your Strom Limited water heater MUST be installed and maintained regularly by a qualiﬁed

professional in accordance with current electrical and plumbing regulations.

• If the chloride content exceeds 200ppm a ﬁltration system should be ﬁtted, failure to do so may

invalidate your warrenty.

• This device has been designed for internal use only, if the system may be exposed to frost please

drain down the system completely, and DO NOT attempt to use the device if you suspect it is frozen.

• Always ensure that the ﬂow temperature is not excessive before use. If the water is too hot please

increase the ﬂow rate and wait for the temperature to reduce.

• As part of the product maintenance regularly clean the ﬁlter washer provided, failure to do so may

reduce your ﬂow rate over time.

• The HandyWash is not designed for modiﬁcation in any way, please do not ﬁt anything to the unit

unless otherwise recommended.

• When comissioning the water valve should be adjusted to increase or decrease the water ﬂow to

the unit, this in turn will control the temperature of water from the outlet, slower increases the

temperature, faster decreases the temperature.

• Each unit is tested at our factory before its departure, a little residual water is normal, and the product

should be ﬂushed through before use.

• Never try to operate this device if your water supply is blocked or turned oﬀ, doing so could cause

premature failure of your device.

• Any damage to the wiring or integrity of your device should be assessed by a qualiﬁed electrician, and

the device should not be used until the unit or wiring has been repaired.

• The minimum water supply available at the point of install is 0.2 Bar.

• If at any time the water heater begins to overheat or produce water too hot for use and increasing

the ﬂow doesn’t cure the problem please isolate the electrical supply and consult your installer or our

technical team immediately.

BEFORE INSTALLATION

This installation must only be performed by a qualiﬁed electrician and installed to all relevent national

and local electrical and plumbing regulations. Failure to do this could render the install both illegal and

dangerous. Before installation please ensure the following:

1. Your Strom Limited appliance is intact, and the ﬁttings are supplied & complete.

2. Please make sure the mains power supply, water pressure, earthing condition, and cabling reach the

standards required for installation as required by all relevent regulations & laws.

3. The appliance must be properly earthed in accordance with all current regulations and laws.

4. If the unit is not to be used for a prolonged period of time please drain down and isolate the electrical

supply of the product.

5. Position the unit upright with all plumbing connections at the bottom of the unit.

6. During the installation please test water ﬂow is achieved at the tap before connecting the power

supply. If the heater is activated without water supply the unit may be damaged.

7. Check incoming mains water pressure, if greater than 6 bar please reduce the pressure with a

pressure reducing set available from your merchant. Failure to do so may damage your device &

render your device warranty void.

WIRING SCHEMATIC

INSTALLATION

• This diagram is provided for your reference of the internal wiring of your Strom Limited water heating

product.

• No attempt should be made to change the internals of your water heater, doing so may be dangerous

and will invalidate your warranty.

• Your product MUST always be wired by a qualiﬁed electrician in accordance with all the relevent

regulations and laws in place at the time of installation.

ACTION 1

ACTION 2

ACTION 3

1. To connect the Sprayer Spout, start by ensuring the temperature control dial is set in the oﬀ position.

Remove the two screws at the base of the unit and then remove the front cover of the unit (ACTION 1).

Push the end of the water outlet sprayer ﬁrmly into the outlet out of the heating element and ensure

it is all the way in (ACTION 2). Push the plastic sleeve as high up as it can go then insert the circlip

into the two holes of the plastic sleeve (ACTION 3). Ensure the water outlet sprayer is ﬁrmly installed.

2. Using the template provided work out where best to secure this unit on to the wall ensuring that it is

level. Mark up the drill holes through the holes in the template then drill through and place wall plugs

into the holes. Oﬀering your unit up to the wall and screw into the corresponding holes on the unit to

the holes on the wall and ensure the unit is secure on the wall.

3. We suggest ﬁtting an isolation valve or ball valve before the tap to facilitate removal of the unit

and servicing. Connect your cold mains supply to the internal ½” thread’s making sure that the ﬂow

reducing washer provided is ﬁtted the correct way around between the nut and threads.

4. Make the correct electrical connections to the unit, but do not turn the power back on at this stage. A

minimum heat resistance cable size of 1.5mm² should be used. The product can be connected in two

diﬀerent ways:

• Via a fused and switched connection unit taken as a spur from a 13amp ring main.

• As a separate circuit taken directly from a spareway in a consumer unit.

In each case a double pole isolating switch having a contact separation of at least 3mm in each pole,

and a minimum rating of 13amp must be incorporated in the wiring of the appliance.

5. Before replacing the front cover of the unit make sure that there are no leaks from the cold inlet

connection. Place the front cover back on to the unit whilst still ensuring the temperature control dial

is still in the oﬀ position. Finally replace the screws at the base of the unit.

REMEMBER: Before turning oﬀ the water supply to the unit you must isolate its electric supply, operating

the tap while there is no water can cause premature failure and invalidate your warranty. DO NOT turn on

your electric supply at this time.

COMISSIONING

1. Flush the unit completely for 20 seconds, to do this turn the control dial to the fully open cold position,

in the case of the automatic model please restore power to the unit only when the control dial is in

the fully cold position.

2. Once ﬂushed for 20 seconds please move the control dial to the oﬀ position and in the case of the

manual model please also restore power.

3. To set the ﬂowrate and temperature of the unit please set the control dial to the midway position on

the hot side.

4. Whilst in this position please restrict water ﬂow to the unit using the isolating valve ﬁtted before

the unit. Restricting the ﬂow will increase the output temperature, whilst increasing the ﬂow will

decrease the temperature.

5. Once the required temperature is achieved please set control dials on manual models to the oﬀ

position, and set automatic models to the correct temperature ready for use.

6. Your HandyWash is now ready for use.

GENERAL USE

SEHW3KM1

SEHW3KA1

• Turning the temperature dial towards cold will give you cold water, the further towards cold you turn

the temperature dial the faster the cold water will come out of the tap.

• Turning the temperature dial towards hot will give you hot water, the further towards hot you turn the

temperature dial the faster hot water will come out of the tap however, the higher the ﬂow rate the

cooler the water will be. By pushing the control only slightly towards hot the ﬂow rate will be very low

but the water temperature will be very hot. REMEMBER: This product, if used incorrectly can scald, if

the water is too hot increase the ﬂow rate by turning the temperature dial further forwards, if it is too

cool reduce the ﬂow rate by throttling the temperature dial backwards.

• Leaving the temperature dial in the central OFF position turns the ﬂow rate and the heater oﬀ.

REMEMBER: If you are to leave this product unattended for long periods of inactivity please isolate

the electric supply, and drain the product down. After a draindown please follow the comissioning

procedure again.
