3. Glossary
The glossary lists all words, abbreviations and technical terminology used in this
manual, along with a short description of these terms.
Term
Description
TMV
Thermostatic mixer valve controls and maintains a mix of
hot and cold-water temperature for safety and prevention
possible scalding.
Anti-Ligature
Recently we have become aware that there is some
inconsistency in the market as to the exact meaning of
"anti-ligature". When we use this phrase about our
products it means that we have designed and tested the
product to reduce any risk of that product being used as
a ligature attachment point.
BSP
The British Standard Pipe (BSP) thread is a family of
standard screw thread types that has been adopted
internationally for interconnecting and sealing pipe ends
by mating an external (male) with an internal (female)
thread.1
4. Overview
This product is an anti-ligature and highly robust stainless-steel flush fitting ceiling
mounted shower head with anti-ligature/anti-tamper fixings and front facing
removable shower plate.

5.2 Ceiling Mounted Shower Installation.
NOTE: The ceiling mounted shower requires installation following the
guidelines in figures 3 - 6 depending on the mounting method.
NOTE: The following examples refer to the use of Hilti HUS3 masonry screws
for a concrete ceiling. Refer to Hilti data sheet for full installation instructions
of fixing system. If other fixings systems are used, refer to the manufacturer's
literature for torque settings. Tighten sufficiently to prevent removal without
tooling.
NOTE: Exceeding the torque setting for the M5 screws can result in damage to
the mounting plate.
NOTE: It is recommended to apply anti-pick hard set mastic to shower nozzle
plate edges against the wall, (i.e. Sikadur 33).

5.2.2 Method 1: Cast Concrete Ceiling Mounted
(See Figure 3):
1. Create ø80mm clearance hole in the ceiling.
2. Mark fixing hole location with the shower head as a reference.
3. Use 4x pan head, security fixing screws suitable for concrete ceiling material (not
supplied) to fix the shower head to the ceiling (e.g. Hilti HUS3 6mm concrete
screw anchors). Drill ceiling holes as detailed in Hilti data sheet and then retain
plate to the ceiling using installation torque of 25Nm. For alternative fixing
systems, refer to fixing manufacturer’s guidance for torque settings.
4. Ensure the plate is flush against the ceiling to maintain anti-ligature and vandal
properties.

5.2.3 Method 2: Fixing Box
(See Figure 4):
1. Create 85mmx85mm clearance hole in the ceiling.
2. Create ø120mm x 2mm recess for the nozzle box flanges.
3. Using the mounting box as a reference, mark 4x ø6.5mm clearance holes for the
threaded fixings on the back box.
4. Use 8x pan head, security fixing screws suitable for concrete ceiling material (not
supplied) to fix the shower head to the ceiling (e.g. Hilti HUS3 6mm concrete
screw anchors). Drill ceiling holes as detailed in Hilti data sheet and then retain
plate to the ceiling using installation torque of 25Nm. For alternative fixing
systems, refer to fixing manufacturer’s guidance for torque settings.
5. Fit the 4 x M5 screws (Item 3, Fig: 2) through shower plate into ceiling mounting
box. Tighten each screw to a torque of 3.5Nm, a thread lock can be applied
(Loctite 222).

5.3 Water Connections
NOTE: Before you carry out the following steps, flush the water supply pipes to
remove any debris and trapped air.
NOTE: Fit a Y strainer in the water supply feed pipes prior to connection of
solenoid valve, especially on older installations where loose particles from
ageing water pipes can cause a blockage and/or damage to the outlet or
solenoid valves.
NOTE: The shower nozzle must be fed by a blended supply that complies with
the regulatory standards, set to the necessary temperature range(s). If a TMV is
used it must be positioned before a solenoid valve.
NOTE: Use of any pipe sealing compound should be avoided to prevent
blockages and damage to the shower nozzle and water solenoid valves.
NOTE: It is recommended to fit a service isolating tap on the water supply feed
before solenoid valve. This allows for ease of maintenance when required. The
isolating taps are not supplied by Wallgate and should be purchased
separately.
1. Connect ½” BSP female fitting to male ½” BSP thread on shower nozzle
housing.
2. Figures 3, 4 and 5 are for illustration only, installation should be made in
accordance with site-specific plumbing requirements.
5.4 Ceiling Shower Spray Pattern
The ceiling shower will have varying spray pattern dimensions depending on
mounting height and water flow rate. Figure 7 on the following page has a table
indicating the various spray diameters at two different flow rates, 6lpm and 8lpm.

5.5 Commissioning for Use
1. Fully open the water supply isolating tap. Check the system for leaks.
2. Operate the all shower outlet supplies available. Operate the water several times
to make sure all air has been purged from the system.
3. Ensure that the flow rate is correct, and the shower nozzle’s pattern is fully filled.
4. Where a thermostatic mixer valve (not supplied) is fitted to the plumbing system
for the outlet, you may have to adjust the valve to set the correct hot water
temperature. If so, you should do so in accordance with the instructions supplied
by the manufacturer of the thermostatic mixer valve.
5. Leave a copy of this Product Manual with the person responsible on site.

6.1 Operation
1. Fully open the water supply isolating tap.
2. Operate the shower.
3. If the shower is activated by Wallgate controls, i.e. WDC100 or WDC200 the
default run time for the shower is 60 seconds.
NOTE: Further settings can be found in the WDC product manuals which are
also available on the Wallgate website.
NOTE: This product offers no form of temperature control.
6.2 Maintenance
The ceiling shower plate is polished stainless steel and can be cleaned using warm
soapy water or a stainless-steel cleaner. A suitable limescale remover applied to the
manufacturers guidelines is also a safe method for cleaning.
NOTE: Bleach, spray cleaners and abrasive cleaners may damage the surface
and internal parts of the shower.
For ease of cleaning, the spray plate can be removed from the external plate. The
assembly is shown in figure 2.
1. Unscrew the 2x security screws to release the internal plate and an O-ring.
This can be cleaned separately following the guidelines above.
2. After cleaning reinstall the O-ring, plate, and screws. To do this set the O-ring
on the underside of the internal plate.
3. Push the plate and O-ring into the opening, aligning the 2x holes in the plate
with those on the housing.
NOTE: For maximum vandal resistant properties it is recommended to reapply
Loctite 2700 WRAS approved thread sealant to M4 screws before refitting.

4. Hold the plate in place and screw in 2x screws. Equally tighten to 3Nm.
NOTE: Ensure O-ring is seated in groove correctly, countersunk screws are
flush with the internal plate. The internal plate must flush with external plate to
maintain water seal and anti-ligature properties.
