Important information
Introduction
The Aquarian Thermo is a surface mounted thermostatic mixing valve designed to accept rear entry supplies and has outlet
connections at the bottom or rear. The Aquarian Thermo provides close temperature stability and fail safe protection when
installed on approved gravity or pumped systems and balanced high pressure systems. A cold inlet flow regulator is provided
for use with instantaneous (multipoint) gas water heater and combination boiler applications.
If you have any questions at any stage during installation please contact the Aqualisa customer helpline on 01959 560010.
Exposed pipe work installation
The Aquarian Thermo valve can be adapted for installation using exposed pipe work by purchasing a separate manifold system
to enable this type of installation.
Please refer to the installation instructions supplied complete with the manifold for fitting instructions.
The manifold is available in either white (for white or white/chrome Aquarian Thermo valves) or grey (for use with chrome
Aquarian Thermo valves).
Product codes:
E99MF.20 (white) and E99MF.01 (grey)
should be ordered as required.
Safety information
This product must be installed by a competent person in accordance with all relevant current Water Supply Regulations.
Flushing
Some modern fluxes can be extremely corrosive and, if left in contact, will attack the working parts of this unit. All soldering
must be completed and the pipe work thoroughly flushed out in accordance with current Water Supply Regulations prior to
connection of the product.
Connections
The Aquarian Thermo valve incorporates ‘push fit’ type connections for use with 15mm British Standard copper tube. Tube
should be cut using a rotary type cutter and lubricated using a silicone based lubricant or petroleum jelly (Vaseline or similar)
prior to insertion into the fitting. Supply lines must be flushed clear of any debris before installation of the unit.
Where plastic pipe is to be used, the tube insert must not increase the tube diameter or extend the cut off length by more than 2mm.
The Aquarian Thermo is designed for conventional supplies with HOT on the Left and COLD on the Right as viewed from the
front. However, the Aquarian Thermo can be adapted for use with reversed supplies, but it will be necessary to contact Aqualisa
customer services on 01959 560010 to purchase reversed graphics to enable this operation. Please refer to the reversed
supplies fitting instructions overleaf.
THESE FITTINGS ARE NOT SUITABLE FOR STAINLESS STEEL.
Isolating valves
Suitable isolation valves such as gate valves must be fitted to both supplies in accordance with the current Water Supply
Regulations and our terms of warranty.
Due to their restrictive characteristics, stopcocks and ball type valves that reduce the pipe bore size must not be used on gravity
or pumped installations.
Filters
To ensure ongoing optimum performance the internal control mechanism
‘cartridge’ is protected by a two-part filter system. Debris accumulation
may result in reduced flow from the shower head and noisy operation.
As this condition is not covered by our standard warranty terms, it is
suggested that the cartridge be removed and the filters checked by a
competent person. In the event of any difficulties please contact the
Aqualisa customer helpline for assistance.
