1. INTRODUCTION.
1. INTRODUCTION.
(a) Welcome to the hand wash drier unit. This unit has been designed and constructed from
quality materials to a high standard. The handwash unit can only be installed in a frost-
free or frost protected environment to avoid damage due to freezing pipes. All water
supply pipes to & within the handwash must be suitably insulated from freezing.
(b) Contained within the packing box in addition to these instructions is:
1 x CME hand wash drier unit,
2 x Installation mounting plates fitted with unit fixing bolts & adjustment nuts,
1 x drawer lock key, 1 x soap liquid (2.5ltr),
1 x Product Manual.
(c) Technically qualified staff should carry out the following instructions. If you have any
further queries about installing or commissioning the handwash unit, help should be
obtained from Wallgate Ltd using the contact details on the front page here.
(d) Details on how to use, care for and service the hand wash unit are contained in the
Operating & Maintenance section of this manual .
2.SITE PREPARATION.
(a) Prepare an opening in the wall surface, accurate to the dimensions shown in drawing
“INSCME_45” on page 4. It is important that the aperture is square and within tolerance to
the stated dimensions as there is very little overlap of the unit fascia (approx 10mm). If
preferable the unit could be fitted as the block work proceeds and a timber lining will also
greatly improve the aperture accuracy. In existing buildings it may be preferable to build a
stud wall to house the unit as an alternative to preparing an aperture in the wall.
(b) The unit is held between two metal mounting plates that are fixed to each side of the
aperture. If support is required above the aperture then a suitable lintel must be installed.
(c) Complete all surface finishes (i.e. screed, plaster or tiling) to the wall before fixing the
mounting brackets, as these must be fitted flush with the finished surface.
(d) An electrical supply should be provided with a switched fused spur-13Amp, double pole
connection point that is local to the unit (the contact separation of the fused spur switch
should be at least 3mm). A suitable cable with a minimum conductor size of 1.5mm sq.
should be connected to the fused spur switch ready for connection to the unit.
(e) A mains cold water supply with a min pressure of 1.75bar should be provided within the
wall cavity below the aperture and terminated with a suitable isolating tap. Final
connection to the handwash unit water inlet (15mm compression) may be made with a
flexible mains rated (WRC approved) hose. If the unit is to be connected to a gravity
(tank) fed supply further advice should be requested from Wallgate.
(f) A waste outlet connection of 32mm (1¼”) should be provided within the wall cavity below
the aperture.
3. APPLIANCE PREPARATION & FITTING.
(a) Remove the unit mounting plates from the packing box. They are packed inside plastic
bubble & placed to one side on top of the handwash unit.
(b) Fit the mounting brackets to the aperture sides ensuring that they are perfectly level
horizontally & vertically with each other. Screw holes are provided on each plate to secure
them, ensure that the screws are of a suitable size (No 10 x 30mm long minimum).
Remove the four unit fixing bolts & washers from the mounting plates & retain in a safe
place. Do not remove the brass nuts fitted to the bushes on the plates but ensure that
they are fully screwed onto each bush hand tight only.
(c) The unit should not be lifted out of the packing box. Instead, cut down each of the box
corners and lay the sides down flat. Remove the pack containing the keys & retain in a
Handwash Installation & Commissioning
Instructions for CME model.

safe place. Cut away the plastic film around the unit and remove the four polystyrene
support corners. Do not pick up the unit by the fascia panel edges but support it below the
white cabinet.
(d) Using a RESIST-TORX T30 security key undo the two screws on the unit top fascia panel
and lift the panel off. Place it in a safe place resting on its rear face.
(e) Release the three screws securing the inner top panel metal cover & remove panel. If
more than one unit is being installed, ensure the panels are kept with each unit.
(f) Using the other key type provided, unlock the lower drawer locks (2). Pull open the drawer
& remove the plastic soap container & hook over the soap tube and priming switch into
the wash basin on the unit.
(g) Remove the drawer from the unit by pressing the black plastic levers that are located on
each slide. Note that the left lever should be pressed down while the right lever is lifted
up. Pull the drawer out from the unit until it is released from the slides. This operation may
require two people or alternately stand the unit up on its base with a pad below it to raise
the drawer off floor level.
(h) Move the unit to the aperture and pass the electrical supply cable through the entry hole
on the back of the cabinet (located towards left-hand side).
(i) Lift the unit up into the aperture and secure to the mounting plates with the bolts &
washers provided. Tighten (hand tight only) the bolts half way into the bushes only at this
stage.
(j) Adjust the brass nuts on the bushes by unscrewing them so that they meet the sides of
the cabinet. The nuts must be adjusted evenly each side so that the cabinet is positioned
centrally in the aperture. Extra care must be taken with the two lower points to avoid
distorting the cabinet sides in too far which will then prevent the satisfactory operation of
the drawer in its slides. The cabinet sides should be set apart a distance of 541mm (21
5/16”) to their outer edges. Once all four points are set, press the unit fully into the
aperture and tighten the four bolts.
4. ELECTRICAL CONNECTION.
WARNING: This appliance must be earthed.
(a) The CME is designed for a fixed wire type installation.
(b) The unit should be installed by a qualified electrician in accordance with the current
Nationally Approved Regulations (IEE).
(c) Terminate the supply cable into the terminal block positions “L E N” located on the left
side within the cabinet and secure it within the cable clamp. The supply cable must not
come into contact with any other components or wiring within the unit.
(d) Earth bonding should be carried out to comply with the Nationally Approved Regulations
(IEE). Connections must be made to the following points: Water supply pipe, Sink waste
outlet & Equipotential earth connection for bonding together multiple units installed,
(connection positioned on back of cabinet behind drawer).
5. WATER SUPPLY & WASTE CONNECTION.
IMPORTANT! For installations liable to freezing conditions, frost protection & pipe insulation
must be fitted.
(a) Prior to final connection of the water supply to the unit, the pipes must be flushed through
so as to remove any debris & air locks.
Warning: Failure to carry this out may result in damage and failure of the unit.
(b) Complete the water connection to the plastic tap/flow regulator on the unit, taking care
that any sealing compounds used are not excessively applied, which may cause a
blockage.
(c) For the waste connection an appropriate trap (not supplied, recommend McAlpine type
SB10 or SP10) should be fitted to the units sink waste (1 ¼” BSP). Ensure the trap is
positioned only on the centre line of the unit so that it does not interfere with the drawer
unit. Final connection can then be made to the main waste pipe.

1. INTRODUCTION
Welcome to your handwash unit. The unit has been designed and manufactured from quality
materials. If these user instructions are followed, the unit will give reliable efficient service. If
you need further information, please contact Wallgate Ltd.
The two models are follows:
Push button operation, model CME_41.
Automatic infra-red sensor operation, model CME_45.
It is important that you establish which model of unit you have installed so that you are able
to follow these instructions correctly. The cycle times for the unit have been set to provide
highly effective hand washing at low cost.
The installer will have passed to you this manual & the key to open the lower drawer panel.
The upper fascia panel is secured with two security screws which require a RESIST-TORX
T30 key.
2. OPERATING THE UNIT
The unit is switched “ON” or “OFF” by the isolation switch behind the top door panel or at the
mains switch located near the unit on the wall. If a fault occurs with the unit, then it must be
switched “OFF” until a qualified engineer has repaired the fault.
WARNING: Unqualified personnel must not remove the internal cover, due to the risk of
electric shock.
For the CME-41 push button operated model follow the instructions below:
For soap dispensing press the hand or foot button marked “SOAP”. Dosage depends
entirely on the number of times the button is pressed. The electric type pump runs for a
pre-set time 0.3 seconds to deliver approximately 5ml of soap. This can only be adjusted
by consulting the manufacturer. The soap button however can be pressed several times
for repeat operations if more soap is required.
For water dispensing press the push button marked “WATER”. The time cycle has been
set to 12 seconds. The setting can be adjusted as detailed on the following page titled
“Time Cycle Adjustments”. The water cycle can be repeated by pressing the button again.
For hand drying, press the hand or foot button marked “AIR. The time cycle will have been
set to 35 seconds and can be adjusted as detailed on the following page “Time Cycle
Adjustments”. The air cycle can be repeated by pressing the button again.
Note: The water & air cycles can be interrupted when in operation. For example, when the
water cycle is running, pressing the air button will stop the water and start the air cycle.
Similarly, pressing the soap button would cancel the water cycle if it were running at the time.
OPERATING & MAINTENANCE INSTRUCTIONS
FOR MODELS CME_41 & CME_45.

For the CME-45 model, IR sensor operated, follow the instructions below:
When you place your hands into the wash basin an automatic cycle shall commence as per
the sequence now detailed:
Soap dispensing for 0.3 second.
Followed by a delay of 1 second.
Warm Water for 12 seconds.
Followed by a delay of 1 second.
Air drying for 35 seconds.
Followed by a delay of 3 seconds after which another cycle can then be activated.
Note that another cycle shall not start unless your hands or any other item in the sensor
detection zone/range is removed momentarily.
Time Cycle Adjustments.
To adjust the time cycle settings for water and air dispensing, access must be made into the
cabinet behind the unit upper fascia panel, a RSIST-TORX key is required to remove the two
screws securing the panel. An internal cover plate is mounted behind the upper front fascia
panel. It is recommended that only qualified personnel carry out inspection/adjustments due
to the risk of electric shock if the appropriate
precautions are not taken. Switch OFF the
electrical supply at the fused spur or mains switch
board.
To the left of the internal cover plate, switch OFF
the “Electrical Isolator” to ensure the electrical
supply to the unit remains disconnected. Remove
the inner cover plate by releasing the screws
securing it and then ease it out from the unit.
The handwash will be fitted with one of two
electronic controllers, (TCU041 or TCU100) which
is mounted towards the top inside face of the
handwash housing. The TCU041 controller is
used on units with just soap, water and air
functions, push button operated. The time
settings may be adjusted by following the
adjacent instructions. The TCU100 is fitted to the CME_45 model, time cycles may be
adjusted using the onboard ‘Control Interface module’. For further details contact Wallgate.
After all adjustments are completed ensure that the internal cover plate is correctly replaced
& that the switch Electrical Isolator is in the ON position (Red light illuminated). Replace &
secure the upper front fascia panel with the two security screws.
3. REPLENISHING THE SOAP
a) Open the lower drawer with the keys provided, and remove the soap container lid. Refill
the container to the MAX level mark avoiding any accidental spillage. Replace the
container lid ensuring that the tubing is inserted fully into the container. The
recommended soap for use in this unit is a free flowing liquid soap. It is particularly
important that creams or gels are NOT used, as this will cause a blockage. The
recommended soap and its specification is available from Wallgate Ltd.
b) To prime the unit with soap for models with button operation push the soap button several
times until the soap comes through the dispensing nozzle. For automatic units a prime
switch is fitted and is located in the drawer with the soap container. When the prime
switch is pressed it will operate the pump. Press it until the system is primed. Problems

with priming the system can usually be cured by pumping warm water through the
system. It is recommended that this should be done occasionally to clear any solidified
soap from the tubing and dispensing nozzle.
c) Close and lock the drawer. Depending on the usage, the soap level should be checked
periodically.
4. ADJUSTING WATER TEMPERATURE
a) An inlet flow control valve is located within the unit cabinet towards the lower left side.
Adjusting the water flow rate through the instantaneous heater controls the temperature of
the water being dispensed from the unit. The recommended flow rate is 1.6 litres of water
per minute, to achieve a temperature between 35 to 45 degrees centigrade depending
upon the ambient level of the cold supply. The units 3Kw heater will raise the ambient
level by approximately 25 degrees centigrade.
b) Adjust the flow by rotating the valve clockwise to increase the temperature, &
anticlockwise to decrease the temperature. Make small adjustments and activate the
water cycle to check the effect.
Note that the unit is fitted with a safety flow switch, which will only operate the water heater
when the flow rate is set above 1.2ltr/min.
5. MAINTAINANCE
Wallgate operates a comprehensive service package, details of which can be obtained from
our After Sales Service department. A full spare parts facility is also available.
WARNING! The water heater is an open outlet type and under no circumstances should the
water outlet nozzle be allowed to become blocked, or connected to any pipe or tap.
