Water SUPPLY CONDITIONS
4.0
Water regulations
The fittings covered by this installation and maintenance instruction should be installed in
accordance with the water regulations published in 1999*, therefore Armitage Shanks would
strongly recommend that these fittings are installed by a professional installer
*A guide to the Water Supply (Water Fittings) Regulations 1999 and the Water Byelaws 2000, Scotland is published by WRAS (Water
Regulations Advisory Scheme) Fern Close, Pen-y-Fan Industrial Estate, Oakdale, Newport, NP11 3EH.
ISBN 0-9539708-0-9
4.1Introduction
This sequential thermostatic lever operated mixer is manufactured to the highest standards and have
approval to TMV3 which permits it to be installed in healthcare establishments such as hospitals, nursing homes and residential care homes. When installed in healthcare establishments the supply conditions detailed in Table 1 must be observed and the commissioning and servicing requirements detailed
on section 7 & 8 must be followed.
For other installations this is not a requirement.
4.2
Supply Pressure Overview
This mixer is designed to be installed on all types of plumbing systems.
Hot and cold water supply pressures should be reasonably balanced, however, the mixer will function
within specification on unequal pressures up to 5 :1.
Mixer comes complete with integral combined check valves & 5 lpm flow regulators. A pair of in-line
service valves with strainers are supplied to permit isolation of the product for maintenance.
The service valves should be installed in an easily accessible location. The minimum pressure for the
correct thermal operation is 0.2 bar. However, in order to achieve an acceptable flow performance at
very low pressures it may be necessary to replace the flow regulated check
valves (14a) with simple check valves (14b). See section 11 & 12.
IMPORTANT: DO NOT REMOVE check valves completely.
4.3
Healthcare Establishments
In accordance with the NHS model engineering specifications DO8 this valve has approval for
the following applications:
High Pressure
HP-
-S
Low Pressure

Note:
Fittings operating outside these
conditions cannot be guaranteed
by the scheme to operate as TMV3.
*52°C absolute minimum can
be used but not recommended
Table 1 Supply conditions for healthcare establishments
Effectively this means:
Differential between HOT and COLD inlet temperatures ( ∆t ) must be 32C° min and 60C° max
Differential between HOT inlet temperature and MIXED temperature ( ∆t ) must be 11C° absolute minimum but > 14C° preferred
See 7.3 Audit checks on TMV’s.

Mounting location
Decide on a suitable location for mounting the mixing
valve on the wall. Give consideration to the mounting
depth as shown here.
The plaster guard (blue moulding) is marked at the top
end with MINIMUM & MAXIMUM to help the installer
achieve the correct depth. The dimensions are shown
from the centre line of the outlet pipe to the finished
surface (which could be tiles).
The back support (white polystyrene moulding) can be
left in position to support the brass valve & act as a
levelling guide. Use a spirit level for accuracy.
The profile of either the back support or the large side
of the plaster guard can be used as a guide for
marking out the size & shape of the aperture required
in the finished wall for the sealing the trim kit.

In-line service valves
IMPORTANT: The inline service valves supplied with this product must be fitted into the
pipe-work. See section 10 for more details.
Consider a suitable location for the service valves. During installation, the service valve
can be held with grips or use an adjustable spanner on the flats of the valve body.
Orientate the service valve such that the filter cap & isolating screw are easily accessible
for future maintenance.
Fit pipes to both sides of the service valves & make good the all the joints.
.
NOTE: When the isolator screw slot is parallel to the valve body, the valve is open &
permits water to flow. To close the valve, rotate the isolator screw 90°. Valves can be left
closed until after the trim kit has been fitted.
Plaster guard removal
To remove the plaster guard, undo the two screws
shown here. Use a “long reach” flat blade screw driver.
Valve fixation
If the pipe-work does not sufficiently support the valve,
then two suitable screws can be fitted into the two
holes shown.

Blanking plug
A ½” blanking plug is supplied with a copper sealing washer. Blank off the outlet port not
being used. Above, the top port is shown with the plug fitted. With the seal in place, use a
10mm hexagonal key to tighten plug into the port being blanked.
Check valve housings
The top surfaces of the check valve housings are marked RED on the left side & BLUE on
the right side. The markings signify the HOT & COLD water supply sides respectfully.
With the valve secured, pipe-work attached, & blanking plug fitted, the plaster guard
can be reattached to the valve to protect it from subsequent decorating tasks.
Make good the wall up to the profile of the plaster guard.
Check that all joints are securely tightened, test for leaks.

To perform a CWI test, operate the product by rotating the lever fully to the right.
Then conduct the following procedure:
1. Record the steady state temperature of both hot and cold water supplies. Note the ∆t.
2. Record the temperature of the mixed water at the outlet.
3. Isolate the cold water supply (by rotating the isolating screw 90° & monitor the flow of water
from the outlet.
If the flow ceases, CWI test passed:
1. Restore the cold water supply by rotating the isolator screw 90° clockwise.
2. Re-check the temperature of the stabilised mixed water at the outlet to ensure it is still correct.
Accept & record mixed temperature.
If there is an ongoing flow of water from the mixed water outlet, then 5 seconds after CWI collect the
discharging water into a measuring vessel for 60 seconds. To pass the CWI test the volume of
collected water should be less than 120ml.
If the product fails CWI test, see FC2 (see section 7.4). Follow product maintenance (see section 9)
and servicing (see section 8) instructions.

8.1
FREQUENCY OF REGULAR SERVICING
The purpose of servicing regularly is to monitor any changes in performance due to changes in either the
system or the product. This may highlight the need to adjust either the supply system or the product.
These products should be audited 6 to 8 weeks and again 12 to 15 weeks after commissioning. The
results are to be compared against original commissioning settings.
If there are no significant changes at the mixed temperature outlet then a 6 monthly servicing cycle may
be adopted. Otherwise, servicing checks should be carried out more frequently
(e.g. every 4 months).
Follow the recommended auditing and maintenance procedures detailed in sections 7 & 9.
During servicing, note the following:
1. Repeat the procedure of recording and checking supply temperatures. (The same type of measuring
equipment should be used)
2. If the temperature has changed significantly from the previously recorded valves, the
following should be checked:
a. All in-line or integral valve filters are clear of obstruction.
b. All in-line or integral check valves are clean and working properly to prevent backflow.
c. Any isolating valves are fully open.
d. The thermostat is free of debris
3. When satisfied with the mixed outlet temperatures re-record the temperatures.

MAINTENANCE
When installed in a healthcare application, we recommend that the commissioning and maintenance
procedures, detailed under 7 & 8, be carried out.
9.1
Adjustment of the mix temperature
• Note: Cartridge is factory pre-set at 40±1°C at 3 bar
1. Prise out the cover button on the handle & unscrew the retaining screw using a 4mm
hexagonal key. Move the lever to the fully on (max) position & then remove the handle.
Refer to section 5.2 Handle fixation.
2. Remove the face plate & black mouldings (see section 5.1). Slide off the cylindrical
chrome shroud & grey spindle extension to expose the thermostatic cartridge.
3. Remove the upper Anti clockwise stop ring (slide off spindle).
4. Rotate spindle (use lever handle if necessary) to achieve correct mix temperature.
(40±1ºC) Rotate clockwise to reduce and anti-clockwise to increase.
5. Refit the upper stop ring against cartridge stop face.
Note: 1. this is the normal maximum temperature range for the product and as such there is a
wide zone of spindle movement that gives this mix temperature. For best performance you
should refit the stop at the first point of anticlockwise rotation that achieves the desired setting.
Note: 2. if you are unable to achieve 40 - 41°C Max and you have the correct Δt’s it may
be due to fine debris. See 9.2 Removal and inspection of cartridge.
6. Upon successful completion of the temperature adjustment, conduct the Cold Water
Isolation (CWI) test (See 7.5) to ensure product is working properly.
7. Refit the spindle extension, cylindrical shroud & face plate kit (see section 5.1). Refit the
handle (see section 5.2).
8. Record the mix temperature.

9.2
Removal and inspection of cartridge
After checking that supply conditions are within the specified parameters (see table 1), if the fitting malfunctions or should the test results fail to fall within the specified limits consider replacing the
cartridge with a new one. See 9.3 Important notes on debris.
1. Remove the face plate (see section 5.1 & 5.2). Slide off the cylindrical
chrome shroud & grey spindle extension to expose the thermostatic cartridge.
2. Isolate the fitting by closing the isolating valves (see section 10).
3. Unscrew the cartridge from the body with a 36mm A/F deep socket. Inspect cartridge
for damage. Expect a small quantity of trapped water to escape when the cartridge is
unscrewed.
4. Replace cartridge if necessary and reassemble cartridge into body.
5. The replacement cartridge should be tightened to a torque of 15Nm.
(To re-secure the cartridge we recommend the use of Permabond A011 or equivalent applied to the
thread of the cartridge)
6. Reinstate the supplies.
7. After fitting the new cartridge start the test procedure from the section on commissioning.
• Redo the Cold Water Isolation (CWI) test (See 7.5).
• Once satisfied with the CWI test, re-check and if necessary, adjust the maximum mix temperature,
(See 9.1).
• Refit the spindle extension, cylindrical shroud & face plate (see section 5.1).
• Refit the handle (see section 5.2).
• Record the mix temperature.

9.3
Important notes on debris
Although this product is protected by built-in filters, debris can still find its way to the thermostat housing
area. This can happen during servicing for example. Remove cartridge (see section 9.2) and carry out
an inspection.
9.4
Thermostatic Cartridge Ageing
Following many years of normal service you may notice the following:
1. The need to carry out more frequent adjustment of mixed temperature.
2. The thermostatic element may not pass the CWI test.
These issues could be due to the ageing of the thermostat which loses some expansion capability over
time.
These are the principle objectives of testing, as they serve to indicate to maintenance staff the declining
performance capability of the thermostatic cartridge.
For this reason the audit testing flow chart highlights that 2nd Instance CWI test failure or 2nd instance
mixed deviation even with stable ‘as commissioned’ supply conditions and correct inlet supply ∆t’s, is
potentially the first indication of the need to replace the cartridge.
10
Inline Service Valves
The service valves contain filter & isolating valve functions.
Isolation valves facilitate 4 activities:
1) Cleaning strainers & check valves 2) Servicing the cartridge
3) Disinfection 4) Audit cold water failure testing
Strainers
Each service valve is fitted with a strainer (filter/mesh) to catch any waterbourne debris
To ensure trouble free operation of the fitting, the strainer elements should be checked and
cleaned in accordance with the commissioning and servicing guide (see section 8).
To access the strainer element, simply close the isolating valve and unscrew the strainer cap.
The strainer element should be washed with clean water and refitted.
Use a 22mm spanner on the strainer cap. Reopen the isolating valves upon completion.
Expect a small quantity of trapped water to escape when the strainer cap is opened.

2. Isolate the product, see section 10.
3. Use a 17mm spanner (or socket) to undo the CV15FR valve housings.
NOTE: Expect a small quantity of trapped water to escape when these
housings are opened.
4. Slide the CV15FR valves out from the bottom of the housings.
5. Check/clean/replace the CV15FR valves. OBSERVE ARROW MARKING.
6. Refit the CV15FR valve housings into the shower valve.
Reopen the isolating valves upon completion of task & refit face plate etc…
To achieve a suitable flow rate where supply pressures are very low it may be necessary to remove the
combined flow regulator (item 14a figure 12) and replace with a single check valve (item 14b figure 12).
PRODUCT MUST BE FITTED WITH CHECK VALVES, DO NOT REMOVE THESE.
NOTE: The flow regulator fitted in each CV15FR valve housing is nominally rated 5L/min.
Therefore mixer is flow regulated to max 10L/min

Cleaning chrome surfaces
When cleaning chromed products use only a mild detergent, rinse & wipe dry with a soft cloth. Ideally clean after each use to maintain appearance.
Never use abrasive, scouring powders or scrapers. Never use cleaning agents
containing alcohol, ammonia, hydrochloric acid, sulphuric acid, nitric acid,
phosphoric acid or organic solvents. Use of incorrect cleaning products / methods may result in chrome
damage which is not covered by the manufacturer’s guarantee.
