5. Overview
The Thrii is an integrated hand wash dryer unit with automatic infra-red sensor operation. It is available in a
solid surface or stainless steel (grade 304) material.
The unit should only be installed in a frost free environment, to avoid damage.
All models are identical, with the exception of the fascia material & fascia dimensions.
When hands are placed in the center of the wash bowl, an infra-red sensor activates the hand washing and
drying cycle, supplying soap (liquid or foam), warm water and dryer-air in amounts and intervals preset as
required.
The unit can be installed in a variety of wall types, servicing can be carried out either from the front (fascia
unlocks and whole Thrii swings out) or from within an access duct behind the machine.

6. Installation and Commissioning
The Wallgate Thrii handwash-drier unit is a three-part assembly consisting of a flush support frame and a hinged fascia and
engine assembly. It is necessary to install the mounting frame and prepare the services (electrical, water and waste) prior
to installing the fascia.
It is important that when selecting a mounting position consideration be given to the suitability of the wall
construction, so that it is able to bear the weight of the assembled unit in both the open and closed positions, and able
to withstand the clamping method as shown in Fig.6
6.1 Package Contents
Before you begin the installation, make sure that you have the following items:
1 Support frame
1 Installation instructions
1 Wall frame waste connector
1 Waste pipe 1-1/4” – 1-1/2” adapter pipe

1 Mains electrical plug and lead (6-1/2 ft. length)
1 User instruction label
1 Set of mounting brackets and fixings
1 Fascia
1 Engine
1 Container of liquid soap (2/3 gal.)
6.2 Site Preparation
6.2.1 Installation guidelines
Looking at the front of the unit the fascia hinges are on the right-hand side. For front access allow for the left-hand
edge of fascia to swing out (120°) to allow full internal access. Water, power and waste water connections are
located on the hinged side of the unit.
Make an opening in the wall surface according to the dimensions shown in drawing Fig.4 noting the appropriate
mounting height as detailed on the drawing table A.
The opening must be according to the dimensions given in fig.4. The aperture must be accurate in order for the
door mechanism to work effectively. The unit will be fitted to the support frame supplied. The frame is fixed to the
sides of the wall opening using the frame fixing brackets provided. The front edge of the frame must be flush with
the finished face of the wall. On IPS panel walls such as trespa or corian the aperture in the panel should be lined
on the rear face with 50mm timber studding.
Complete all surface finishes such as screed, plaster or tiling before attaching the fascia to the support frame.
All electrical work must be carried out by a qualified electrician and should be installed in accordance with the
current Nationally Approved Regulation

The installer must:
Provide a 120V 50/60Hz single-phase circuit equipped with a 20 Amp circuit breaker. Locate an outlet in close
proximity to the intended location of the Thrii unit. The Thrii unit is equipped with a 6.5 feet long electrical cord.
A GFCI equipped circuit is recommended, and likely required by your applicable regulations. If so, ensure that a
GFCI is present on the circuit that meets your locally applicable electrical/building/plumbing codes.
The circuit must be equipped with a circuit breaker that is accessible without requiring the fascia of the Thrii unit to
be opened first. Be sure to turn off the circuit breaker before working on or installing the Thrii unit.
Provide a cold water supply mounted behind the wall below the ‘hinge’ side of the aperture. Terminate the cold
water supply with a suitable isolating tap. For optimum operation a dynamic water flow pressure of between 14.5
psi and 43.5 psi is required.
If you are planning on connecting your Thrii unit(s) to a gravity-fed water supply, please contact Intersan in advance
for advice and guidance.
Provide a waste pipe with a 1-1/4” or a 1-1/2” connection and suitable deep seal waste trap behind the wall,
below the ‘hinge’ side of the aperture.
6.3 Installing the support frame, water and waste connections and electric
1. Remove the support frame from the packing box.
2. Orientate the frame with hinge plates on the right-hand side and waste outlet parts at bottom and facing away
from you. The frame front edge should now be facing towards you.
3. Place the frame into the front of the aperture, ensuring it is flush fitting with the finished face of the wall, at the
correct height and perfectly level in the horizontal and vertical planes. The hinge-side of the frame should be hard
up against the aperture.

4. Insert the 4 No. M10 x 150mm (6”) threaded rods through the corner angles on the support frame and into the
brackets as shown in figure above.
5. Tighten all four (4) brackets until the wall frame is held securely in place in the wall opening. It is important that
the frame side members are not distorted when tightening to the wall, as this may prevent the hinge and catch
mechanisms from working properly.
6. Once the frame is securely attached to the wall, if necessary make good any excessive gaps between the frame
and the wall that may not be covered by the fascia.
7. Install the waste connector to the frame as shown in figure below along with the pipe adapter which then is
terminated to the deep seal waste trap as detailed in section 6.2 site preparation.
8. Provide a cold water supply pipe to connect to the inlet connector on the support frame. Note that the water
inlet connector is ½” copper fitting on the main water supply.
If pipe sealing compound is used, avoid applying excessive amounts as particles of sealant can block water
filters and impede valve operation.
Before carrying out the following steps, flush the main water supply pipes to remove any debris and trapped
air. Failure to do so may result in damage and failure of the unit.
9. Connect the deep seal waste trap to the outlet fitting on the support frame.
10. Connect the supplied electrical cable to a 20 amp circuit equipped with an accessible circuit breaker and GFC�if
required per locally applicable code requirements.
6.4 Mounting the fascia
Ensure that the fascia is fully supported until both hinges are fully engaged. Failure to do so may damage the
hinges
For ease of installation it is recommended to have at least two people carry out this operation

1. Remove the fascia from the packing box.
2. With one person holding the fascia, the second person should extend the hinge components on the right side of the
fascia so they are fully extended. Position the fascia assembly so the two hinges are suspended next to the hinge side
lock plates mounted on the support frame.
Have one person hold the fascia so it is suspended where the hinge halves on the fascia are in alignment with the
halves attached to the mounting frame, hook each of the hinges on the fascia side around the corresponding bar each
hinge on the mounting frame side, and latch each hinge. CONTINUE SUPPORTING THE FASCIA UNTIL YOU HAVE
VERIFIED THAT THE HINGES ARE ATTACHED AND SECURE.
Continue supporting the weight of the fascia, and test the ability of the fascia to swing freely on the hinges. If any
binding or limitation in the range of motion occurs, check each of the two hinges to ensure they are fully attached and
secure (see figure below).
3. Engage the ‘Hinge release lock’ spigot, fitted to each hinge to prevent accidental hinge latch release.

4. It is necessary to check the fascia alignment with the frame before proceeding further, as the hinges may need
adjustment. Carefully close the fascia ensuring the door opens and closes freely. In the closed position, visually check
the gap between the fascia and the wall along the hinged edge, and adjust the hinges as appropriate to ensure an
even fit using the adjustment screw on the hinges see figure below. Do not over-tighten as this may result in the fascia
damaging the wall finish. Horizontal adjustment of the fascia door can be configured.
5. Once the fit has been checked, close the fascia fully to check the locking bar operation. The locking bar is spring-
loaded and may require a firm push to engage correctly. To re-open insert the key provided into the fascia lock release
at the base of the fascia, ¼ turn anti-clockwise and push the key up to disengage the lock and allow the fascia to open
freely.
6. For installations where front access is not required in addition to the hinge release lock, engage the 2 hinge side locks,
rotating into the slot provided in the frame as shown in figure below and when the lock bar has been fully engaged,
relocate the top screw fixing into the locking position below, as shown in figure below.

7.1 Operation
The hand wash and dry cycle is activated when your hands are placed centrally into the wash bowl below the dispensing
nozzles. An infra-red sensor initiates the cycle when it detects hands in the bowl area. When the cycle starts, a sequence of
soap, warm water and hand dryer air are dispensed. Note that the hand dryer is programmed to cease operation shortly
after hands have been removed from the wash bowl, or when the pre-set dryer cycle time has been reached.
7.1.1 Soap Operation
There are 2 settings for soap delivery, LIQUID (default) or FOAM. The controls to set the required soap option are located
on engine unit. To change the settings the unit must be powered up. There are 2 controls that need to be altered:
1. At the window to the left of the mains connector there is a small push button labelled ‘Soap’. Press and hold this
button to select the desired setting this will be confirmed by an illuminated LED.
2. Adjust the soap selection switch to position 1.
Ensure that both button setting and soap selection knob position select the same operation. Failure to do so
may result in an incorrect operation.
Low soap level indicator:
A function on the unit can be enabled, to indicate that the soap container level is low. When this function is set to ON
(Default setting is OFF) and the soap is at a low level the bowl light will pulse once per second. To turn ON this
function refer to section 7.2 for “Advanced Adjustments” and select menu item F146 which is the setting for number
of soap operations before the warning light is activated. Setting this to 20 will activate the warning light after 2000
operations. The setting may require adjustment if the number of operations per full soap container is found to be
fewer or greater than the setting.
To reset the warning light there are two options.
a. Press buttons 2 & 3 on the display together & hold for 5 seconds.
