Installation
IMPORTANT: Prior to installation please note the following-
a) The location should be checked before drilling, that no pipes or wires can be
damaged.
b) The supply pipes must come from the bottom.
c) Prepare the supply pipes at the specified height, ensuring that the cold supply is on
the right and the hot supply on the left.
d) Once the supply pipes are prepared, open the isolation valves (not supplied) in the
supply pipes to allow the water to flow into the bath or shower tray, this will clear
any debris from the system.
e) Allow the water to flow for approximately 15 seconds, then turn off the isolation
valves.
Installation
1. Draw around the outer dimensions of the shower tower housing, to allow the wall
recess to be cut. Use a spirit level to check that the housing is vertical and
horizontally aligned.
2. Once this location is set, cut the recess into the wall to a depth of 76mm from the
finished wall surface.
3. Push the housing into the recess to check the fit.

6
4. With the housing in the recess, mark the location of the drill holes that will secure
the housing into the recess, then remove and drill the holes.
5. Insert the wall plugs into the holes and tap flat then re-fit the housing into the
recess. Secure using the screws provided.

7
Please note: The supply pipes to the shower tower must come from the bottom, pass
through the holes in the housing to connect to the 1/2" female nut on the hot and cold
flexi- pipes.
6. Connect the supply pipes to the flexi-pipes ensuring that the seals are fitted, and
the hot supply is on the left, tighten to create a seal.
Please note: It is recommended at this point to carry out a leak test, to check for any
leaks before completing the installation

8
7. Following the leak check, silicone can be applied to the back edge of the panel to
prevent moisture running behind. Once applied, hook the shower tower into
position via the slots, then hook these onto the bars inside the housing.
8. Connect the cone end of the hose to the hand shower ensuring to fit the seal, then
fit the opposite end to the hand shower holder thread, again fitting the seal, and
tighten both ends.
Please note: If using a spanner, cover with a cloth to the protect the finish

Operation
To set the temperature - Turn the bottom dial until the desired temperature is reached.
The product is set so that the handle stops at approx. 38⁰c, this is a safety feature;
it can be overridden by pressing the button and holding while turning.
(However, if the maximum temperature reached is within 10⁰c, the thermostat shut
off function will not work).
The maximum temperature, even after being overridden, should be more than 10⁰c
less than the hot water supply going into the unit.
To control the flow of water -Turn the top handle from OFF to the desired setting.
Troubleshooting
Thermostat not allowing hot water
1. The water is only cold/warm and will not go to hot, this can be due to unbalanced
water pressure - water pressures need to be balanced for correct function.
2. Limescale build up or debris in the thermostat - this will require cleaning out.
3. Faulty thermostat.
4. Product requires re-calibration.
Thermostat either very cold or very hot
1. This is due to the water supplies being connected to the wrong inlet on the tower -
these need to be switched so that the correct water supply connects to the correct
inlet.
Water dripping after being turned off
1. If the water stops dripping after a period of time, this is normal as the water within
the unit needs to drain away, so some dripping may occur.
2. If dripping is continuous the flow control cartridge will need to be replaced.

Maintenance
Poor Flow
1. Remove the shower tower flexi-connectors from the tower and turn on the water
supply to ensure sufficient water is reaching the unit; if it is poor flow, this is not a
product fault.
2. Remove the flexi-pipe on the rear connected to the outlet for the body jets and
hand shower then turn on the water to check water flow is sufficient. If it is good,
but still has poor flow, a blockage may be present in the flexi-pipe, try to clear by
bending and stretching the pipe to dislodge any blockage, if this does not work,
replace the pipe. If the flow is sufficient through the pipes, then using your finger or
a soft brush rub the rubber nozzles to remove any blockage.
3. If none of the above resolves the problem, contact your retailer for further advice.
Thermostat not allowing hot water
1. If the pressures are not balanced you will need to consult a plumber to either
reduce the cold pressure, ensuring that the pressure does not fall below the
minimum, or, a pump may need to be installed to balance the pressures.
2. To remove the thermostat for cleaning or replacement, first, turn the shower on,
then turn off the water supply to the tower by the isolation valves, doing this
releases the pressure inside the unit before removal of the component. Turn the
temperature dial to the stop position and remove the screw from the handle (as
shown). Pull the handle from the mixer, taking note of the stop ring position, then
remove the stop ring if replacing the thermostat, leave fitted if just cleaning. Using a
spanner, remove the thermostat from the unit. To clean, run under warm water and
use a brush to clean away any limescale of debris from the filters.
3. After cleaning, replace the thermostat, tighten back into the unit and re-fit the
thermostat stop ring if necessary, as shown below. Re-fit the handle ensuring that
the stop pin inside sits up against the top of the stop ring, so that it can only pass
this stop position by pressing the button. Re-fit the screw and tighten the handle
until secure.

11
Re-calibration
1. The mixer is set up under factory conditions and so on some occasion’s re-
calibration (re-set of the temperature) is required. To do this, turn the temperature
control dial to the stop position. Remove the handle as advised previously, do not
remove the stop ring. Once the handle is removed, turn the spindle on the
thermostat until 38⁰c is achieved. Once set, re-ft the handle, ensuring that the stop
inside the handle sits against the stop ring.
Thermostat either very cold or very hot
1. If the supply is connected to the incorrect inlet on the unit, it should be a simple
process of turning off the water supply disconnecting the flexi-pipes and swapping
them over.
Water dripping after being turned off
1. To replace the flow control valve, turn off the water supply to the unit, remove the
screw from the handle and pull the handle from the unit using a spanner, then
remove the valve from the unit.
Cleaning
To maintain the surface finish of your product, wipe clean after every use, using a clean
damp cloth, a mild detergent mixture can be used. Do not use abrasive cleaning agents or
materials on the product surface.
