Safety InformationSafety Information
User
This appliance can be used by any persons (including children from 8 years and
above) with reduced physical, sensory, mental or intuitive capabilities or by any
persons with a lack of experience and knowledge of showering, only if they are
supervised or have had the correct instructions on how to operate the appliance
correctly.
Use it correctly and do not let children play with the appliance. Ensure that
the temperature is not set to maximum before showering. Sunburn or skin
conditions can increase your sensitivity to hot water. Make sure that you set the
shower to a cooler temperature.
Do not operate shower if you suspect the water in the heater tank is frozen or
the appliance has been susceptible to freezing conditions.
Do not operate the shower if the spray handset or hose is damaged, twisted or
blocked in anyway.
Do not restrict flow out of the shower by blocking or obstructing the hose or
spray handset.
Do not use other shower hoses and handsets with this shower. Only use AKW
approved products.

Maintenance and Cleaning
Always isolate power supply before cleaning. Do not operate if the shower
unit is frozen. Clean and descale the shower head regularly.
The shower unit and surrounding areas should be cleaned periodically to
remove any accumulation of dirt or other waste materials, using domestic
bathroom and kitchen cleaning materials with a soft cloth.
Do not use abrasive pads or cloths. Do not use strong or concentrated
acidic, alkaline or other cleaning materials as these may damage or
discolour the product.
After cleaning always wash down with water then wipe thoroughly with a
damp soft cloth to remove any cleaning material residue.
DO NOT position the handset to spray water directly on to the appliance.
Children should be supervised at all times if they use the shower appliance
or attempt to clean it.

Installation Requirements
The shower must only be connected to the mains cold water supply.
The shower must not be positioned where it will be subjected to freezing conditions.
The shower must always be mounted on a finished flat, waterproof surface.
The flat surface must cover the full width and height of the back plate, otherwise difficulty may
arise when fitting the cover and subsequent operation of the unit may be impaired.
Never tile up to the shower unit.
Do not seal the shower to the wall with silicone or other sealant.
The water outlet pipe acts as a vent and must never be blocked, restricted or connected to any
parts other than those AKW specifically state for use with the AKW iSure 2 shower.
Before you start work:
Take care when you unpack the product and make sure that you do not inadvertently discard any
small parts. Check the contents supplied against the contents page. If any parts are missing or
damaged, contact the AKW Technical Enquiries team.
Check there are no pipes or electrical cables inside the wall before drilling.
Check that finished walls are sound and free from cracks or loose tiles or grout. Make sure that all
surfaces are clean, dry and free from loose debris or dust.
This product is not suitable for mounting into steam rooms or steam cubicles.
Note; If it is intended to operate the shower in areas of hard water (above 200 ppm temporary
hardness), a scale inhibitor may have to be fitted.

Positioning of the Shower
Shower unit can be mounted either side of riser rail.
Ensure minimum side
and top clearance of
120mm.
Refer to the illustration above for correct positioning of the shower controls and shower handset.
Position the shower unit vertically.
Check there are no pipes or electrical cables inside the wall before drilling.
The height of the controls is dependent upon the type of installation.
DO NOT obstruct the back and sides of the shower as this will prevent the Pressure Relief Device
(PRD) from operating.
Ensure the shower unit is positioned over a bath, shower tray or wet floor.
The showerhead must be directed away from the shower unit, during normal use the showerhead
must not spray directly on to the shower unit.

Water Requirements
Plumbing
The shower hose retainer (supplied in the accessory pack) should be used. The installation should comply with
Water Regulations and prevent water supply contamination.
To ensure activation of the heating elements, the shower must be connected to a mains cold water supply
with a minimum running pressure of 50kPa (0.5 bar) with a maximum static pressure of 1000kPa (10 bar).
For optimal product performance the recommended minimum dynamic water pressure should be 100kPa
(1 Bar). Dynamic pressure should not fall below 50kPa (0.5 bar) for example when other draw offs are used,
such as a flushing the toilet as this can cause the shower temperature to fluctuate dramatically.
Note: An isolating stop valve must be provided on the cold water feed before connecting to the shower.
We recommend that isolation valves (not supplied) must be fitted as close as is practicable to the water
supply inlets of the shower heater whilst being accessible for maintenance and servicing purposes.
Do not install this appliance in a position where it can freeze.
Never fit the appliance to the hot water supply.
Note: If the stated flow rates are not available, it may not be possible to achieve optimum performance from
the unit throughout the year.
Note: If the Pressure Relief Device fails, then call the installer in first instance as there may be a dynamic
pressure problem.

Plumbing Connections
Note: The manufacturer’s rigorous quality systems may require operating the shower with water
at the factory. Any water will be removed where possible, however there may be a small amount of
water residue left in the shower.
There are 8 water inlet points for easy installation and servicing.
The plumbing installation must comply with the local Water Authorities and should be in accordance
with the latest Building Regulations.
Plumbing work must be completed before any electrical connections are made.
Make sure there is a cold water feed near to the installation with a local service isolation valve.
Before assembly, flush the water supply pipes thoroughly to remove debris in the pipework (allow the
water to run with the main stopcock open for about 3 mins), to prevent debris and dirt particles from
blocking the filter which might affect the function of the shower.
DO NOT solder pipes or fittings within 110mm of the shower appliance.
DO NOT fit any form of outlet flow control to the water heater.
DO NOT use excessive force when making connections to the water supply inlet, the flexible hose or
the spray head.
Note: An isolating stop valve must be provided on the cold water feed before connecting to the
shower. The isolation valve (not supplied) should be fitted as close as is practicable to the water
supply inlet of the shower heater whilst being accessible for maintenance and servicing purposes.

Plumbing Entry Points
Determine pipework position and select the inlet option most suited to your situation.
Always prime pipework and flush clear of debris. To prevent a dead leg occurring in the inlet
pipework install the inlet plug into the unused inlet pipe, see separate instruction sheet.
Note:Some water from the factory testing may escape when the bottom blanking plug is removed.

Check List
Plumbing
Check that finished walls are sound and free from cracks or loose tiles or grout. Make sure that the appliance
and all surfaces are clean, dry and free from loose debris or dust.
The unit must be mounted onto the finished wall or tiled surface (on top of the tiles). DO NOT tile up to or
seal around ANY PART of the unit using silicone sealer after fixing to the wall. Special care must be taken
NOT TO BLOCK OR SEAL ANY PRD VENTS ON THE UNIT.
Turn on the water supply and check there are no leaks - no water should flow through the shower at this
point. The maximum static water pressure is 10 bar - The minimum operating dynamic pressure must be
at least 0.5 bar. Recommend that for optimum performance this is 1 bar.
Place absorbent material around the inlet areas in case of leaks.
Check that there are no leaks
Turn off the supply, dry off any water in and around the appliance before connecting or reinstating the
electricity.
Plumbing Check List
Separately flush the pipework to remove any debris before connecting to the shower
Note: For ease of installation and servicing, rear entry pipe is only recommended if the top, side
or bottom entries are not possible. This pipework must not apply strain to the elbow fitting on the
shower. Failure to observe this essential precaution will invalidate the warranty.
Securely fix the shower appliance to the wall and make sure it is vertical.
Do not connect the shower handset yet. Only connect the hose to the shower outlet without the
handset at this time and point the hose into the bath, shower tray or wet floor.
CONNECT PIPEWORK AND SECURE THE APPLIANCE TO THE WALL
