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.

Important information

Siting

For optimum performance, with gravity fed systems, the distance between the bottom of the storage cistern and the shower head should not be less than 1m (when using an adjustable height shower head). If using a fixed head, the highest point of the pipe work must be not less than 1m below the underside of the cistern. Please refer to the system layouts on the reverse of this guide.

Pump installation

UNDER NO CIRCUMSTANCES MUST A PUMP BE FITTED DIRECTLY TO THE WATER MAIN.

A pump must only be used to boost the pressure from tank-fed supplies. A typical layout is shown on the reverse of this guide.

Stored water capacities

The minimum capacity of the cold storage cistern should not be less than 225 litres (50 gallons). The capacity of the hot cylinder must be capable of meeting the anticipated demand.

Pressures

The Aquarian Thermo shower valve is designed to control static pressure up to 10 bar. Where pressures are likely to exceed 10 bar, a pressure reducing valve (PRV) must be fitted into the incoming mains supply. A setting of 3 bar is recommended. It should be noted that daytime pressures approaching 8 bar can rise above the stated maximum overnight.

The Aquarian Thermo is not suitable for mixed supply systems e.g. gravity hot and cold mains.

A suitable PRV is available from Aqualisa.

Gravity fed hot and cold supplies

The cold supply for the valve assembly must be taken directly from the cold storage system. The hot supply may be taken from the vent/draw off pipe of the hot water cylinder at a point below the cylinder connection or alternatively from the underside of the horizontal draw off.

Rising pipe work must not be connected into the horizontal draw-off from the cylinder or to any point in the vent/draw off pipe above the cylinder connection.

CYLINDER TEMPERATURE IN EXCESS OF 65°C MAY RESULT IN POOR SHOWER PERFORMANCE.

To minimise pressure loss we recommend that the hot and cold supplies are run in 22mm as close as reasonably possible to the mixing valve before reducing to 15mm.

A typical layout is shown on page 17.

Balanced high-pressure system

The Aqualisa Thermo cartridge is designed to operate with unvented hot water storage systems up to a maximum pressure of 10 bar. A PRV must be used if either supply exceeds 10 bar. The cold water supply must be drawn from the same mains supply as that to the hot water system (down stream of the cylinder manufacturers pressure limiting valve, where supplied) and the hot supply from the nearest convenient draw off point. Account must be taken of pressure drops that may occur when other draw-off points are used while the shower is in use.

Pipe work can generally be run in 15mm.

A typical layout is shown on page 17.

Combination boiler/multipoint system

The gas water heater must be capable of raising the temperature of the incoming water by 35^irc C and delivering a flow rate of no less than 9 litres (2 gallons) per minute to the shower valve. This is sufficient to operate one outlet point at a time. The Aqualisa Thermo cartridge is designed to operate from the mains at a maximum of 10 bar. If the mains pressure exceeds 10 bar a 'drop tight' PRV must be fitted on the supply pipe after the main stopcock.

The cold supply can be taken from the nearest convenient mains supply and the hot supply can be taken from the nearest hot water draw-off point. Account must be taken of the pressure drops that will occur when other draw-off points are used while the shower is in use.

Pipe work can generally be run in 15mm.

A typical layout is shown on page 17.
