General Information
Operating pressure range: Minimum 0.1 bar, Maximum 5.0 bar.
Maximum static pressure: 10.0 bar.
This product has been tested to the TMV2 scheme which complies with the BS EN
1287:1999 (LP) and BS 1111:1999 (HP) thermostatic mixing valve standards and satisfies
the requirements of the water supply (water fittings) regulations 1999 and current
bylaws.
BS 6700 recommends the temperature of stored water should never exceed 65°C.
A stored water temperature of 60°C is considered sufficient to meet all normal
requirements and will minimise the build up of lime scale in hard water areas (see
Map of Hard Water Regions in the UK on page 26).
If the fitting 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 2 metres to ensure adequate performance.
Note: Nominally equal (balanced) inlet supply pressures are recommended for optimum
performance with mixer showers.
These shower valves should be installed in compliance with the Water Regulations.
If in doubt, contact a registered plumber or your Local Water Authority or the Secretary
of The Institute of Plumbing, address as follows;-

accordance with the following Installation
Requirements and Notes (IRN) to ensure
they meet the requirements of the Water
Supply (Water Fittings) Regulations 1999
and the Scottish Byelaws 2004.
IRN R001: See text of entry for Installation
Requirements or Notes.
IRN R040 - Schedule 2-15 (1): The
fitting shall be installed so that its outlet
discharges above the spill-over level of
any fixed appliance as indicated below:-
For backflow protection in domestic or
installations up to, and including, Fluid
Category 3.
If the fitting cannot be installed as
indicated in the table opposite it shall be
installed as either aor bbelow:
a: with an approved double check valve
assembly or some other no less effective
backflow prevention device immediately
upstream of the inlet.
b: so that it draws water by gravity only

Installation Requirements
Flow Regulators
This shower valve is supplied with 2 x 7
litre per minute flow regulators loose in
the box (pre-fitted to ARECO SHXSMFF2
C) which must be fitted in each water
inlet when installed in conjunction with an
instantaneous water heater/combination
boiler.
Fitting both flow regulators and 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.
In the event that this shower valve is not
installed with an instantaneous water
heater/combination boiler, the flow
regulators may be removed. Please follow
the steps detailed to remove the flow
regulators.
Using a thin flat bladed screwdriver or
similar tool, carefully prise the inserts out
of both inlets (1& 2).
With the inserts removed from the inlets,
the flow regulators must be fitted as
shown, with the small diameter first (3&
4).
Note: The ARECO SHXSMFF2 C is
supplied with the 2 x 7 litre per minute
flow regulators pre-fitted. If required they
can be removed and the inserts supplied
loose in the box fitted.

Installation - Riser Rail
1. Mark the position
Position the assembled riser rail on the
wall, bearing in mind the different heights
of people likely to use the shower and the
length of the hose when connected to the
shower.
With the riser rail vertical, mark the wall
bracket positions onto the wall.
Release the slider handle and remove the
slider and wall brackets from the rail.
2. Attach wall brackets
Position the bottom wall bracket onto
the marked position on the wall surface,
