Recommended Usage

Commercial Health Care
This product has been tested to the Water Regulations Advisory Scheme (WRAS) and
satisfies the requirements of the Water Supply (Water Fittings) Regulations 1999 and
current bylaws.
For full Installation Requirements & Notes (IRN) please visit www.wras.co.uk/directory.
BS7600 recommends the temperature of stored water should never exceed 65ºC. A
stored water temperature of 60ºC is considered sufficient to meet all normal
requirements and will minimise the build up of lime scale in hard water areas.
If the shower valve is installed at low pressure (tank fed), then the minimum distance
from the highest installed position of the showerhead to the underside of the cold tank
should be at least 1 metre to ensure adequate performance.
Note: Nominally equal (balanced) inlet supply pressures are recommended for optimum
performance.
This shower valve should be installed in compliance with the Water Supply (Water
Fittings) Regulations1999 and the Scottish Bylaws 2004.

1. Two outlet diverter
This outlet allows the user to divert the
flow of water from one water outlet to
another. E.g. Fixed rigid riser or an
adjustable riser.
2. Temperature control
Adjustable temperature control.
Turn the handle clockwise for a cooler
temperature.
Turn the handle anti-clockwise for a hotter
temperature.
3. Single outlet stopcock
Allows the user to operate another water
outlet e.g. body jets while one outlet from
the top diverter is also being used.
This outlet also allows the user to use this
outlet independantly.
Note: Both the bottom stopcock and one
of the top diverter outlets can be used
together. If both of these outlets are used
together the flow will be shared between
both outlets.

CAS SHC3DIV C shown

Specifications
Inlet connections: 15mm compression with 150mm between centres.
Minimum working pressure: 0.2 bar
Note: This product has been designed to deliver a high flow of water on low pressure
systems, however depending on the installation, type of system and shower accessories
used, a higher pressure maybe required to optimise the showering experence.
Maximum working pressure: 5 bar
Maximum static pressure: 10.0 bar
Note: Static pressure is the build up of pressure when the valve is closed.
Supply requirements:
Minimum cold water supply temperature: 5ºC.
Maximum cold water supply temperature: 25ºC.
Maximum hot water supply temperature: 80ºC.
Note: The inlet hot water temperature must be at least 10ºC above the required blend
temperature (e.g. shower temperature 43ºC: minimum hot water temperature 53ºC).
System requirements:
Gravity fed hot & cold (Equal pressures)
Gravity fed hot & mains cold (Differential pressure, maximum ration 5:1)
Unvented systems
Instantaneous water heater (Combination boiler)
Pumped system
Note: When using a pumped system we recommend that an essex flange is used.

Flow Regulators
This shower valve is supplied with a 5 and
7 litre per minute flow regulator loose in
the box which must be fitted if the shower
valve is installed in conjunction with an
instantaneous water heater / combination
boiler.
With both flow regulators fitted and by
turning the water heater / combination
boiler to its hottest setting, will ensure a
sufficiently hot water supply to the shower
valve during winter months (in the UK),
when the mains cold water supply is at its
coldest.
To fit the flow regulators
Remove the inlet elbows ensuring the
filter washer is also removed. carefully
remove the plastic inserts from the valve
inlets and push in the flow regulators. The
green 7 litre per minute flow regulator
must be fitted to the cold inlet and the
yellow 5 litre per minute flow regulator
must be fitted to the hot inlet.
Place the filter washers back into the
elbow nuts and tighten the nuts fully onto
the outlets.
In the event that this shower valve is not
installed with an instantaneous water
heater / combination boiler, the flow
regulators do not need to be fitted.

adjustment.
Run a bead of waterproof silicon sealant
around the inner edge of the concealing
plate.
Slide the concealing plate onto the shower
valve control handles and apply firm
pressure to ensure to silicon sealant
spreads.

Installation - Rear Access
Rear access installation is designed for
new installations where there is no
shower valve already installed. Once the
shower valve is secured in the wall cavity
the wall should be finished and tiled.
Access is required from the rear for future
servicing of the shower valve filters. The
cartridge can be accessed from the front.
Before Installation
Flush through the pipework to ensure
removal of any debris. Turn off the mains
water supply and close any isolating
valves.
1. Install shower valve
Install suitable battons (if required) onto
the rear cavity wall. Place the shower
valve in the required position and mark the
fixing holes.
Drill suitable holes and insert the wall
plugs (if necessary). Securely attach the
shower valve to the wall / battons using
the screws supplied.
2.Connect water supply pipes
Insert 15mm hot and cold water supply
pipes into the inlet connections and
tighten nuts, ensuring the olives are fitted.
3. Plumb in outlets
Insert 15mm pipework into the top and
bottom outlets and plumb into the users
chosen products. Ensure the olives are
fitted when tightening the nuts.
Important: The ORB SHC3DIV C can be
installed either portrate or landscape.
If the valve is installed landscape the hot
water inlet must be at the bottom with the
cold water inlet at the top.
