Introduction
The product is an exposed bar valve shower complete with fixed and adjustable height shower heads.
The thermostatic valves provide close temperature stability and fail safe protection on appropriate high pressure
systems.
The product is suitable for use on high pressure, combination boiler and boosted gravity systems.
The product is supplied with a 5 year guarantee.
Safety information
This product must be installed by a competent person in accordance with all relevant current Water Supply
Regulations.
THE SHOWER MUST NOT BE USED WITH A HOT WATER SU LY TEM ERATURE OVER 65ºC.
The product is designed for domestic use only.
roduct specification
These products are suitable for balanced high pressure, combination boiler systems and boosted gravity systems.
Pressure range 1.0* – 10 bar max (static).
* The combination boiler UST have a minimum rating of 24kW (80,000 Btu) and be of the type fitted with a fully
modulating gas valve.
If in any doubt, please contact the appliance manufacturer before installation commences.
Connections
This product is designed for conventional supplies with HOT on the Left and COLD on the Right as viewed from the
front.
Supply lines must be flushed clear of any debris before installation of the unit. Any debris accumulation in the shower
valve and head may result in damage and poor performance.
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.
Filters
To ensure optimum ongoing performance, products are protected by inlet filter assemblies in the internal waterways.
Debris accumulation may result in progressively reduced flow through the showerhead and noisy operation.
Isolating valves
Suitable full way isolation valves must be fitted to both supplies in accordance with 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 pumped installations.
Important information
AQ150:Midas 15/9/15 12:15 Page 2

ressures
The cartridge is designed to operate from the mains at a maximum of 10 bar. If the mains pressure exceeds 5 bar a
‘drop tight’ PRV must be fitted on the supply pipe after the main stopcock. A setting of 3 bar is recommended. It
should be noted that daytime pressures approaching 8 bar can rise above the stated maximum overnight.
A suitable PRV is available from Aqualisa.
! This product is not suitable for mixed supply systems, e.g. gravity hot and mains cold.
Combination boiler/multipoint system
The product is suitable for use with combination boiler systems. The combination boiler UST have a minimum
rating of 24kW (80,000 Btu) and be of the type fitted with a fully modulating gas valve. This is sufficient to operate
one outlet point at a time.
If in any doubt, please contact the appliance manufacturer before installation commences.
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. A typical layout is shown overleaf.
Balanced high-pressure system
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.
A typical layout is shown overleaf.
Boosted gravity fed hot and cold supplies
Services must be installed according to good plumbing practice having regard to pipe sizing, long pipe runs and
low-head situations.
ump installation
LEASE REFER TO THE MANUFACTURERS UM INSTALLATION GUIDE FOR UM INSTALLATION
INFORMATION.
UNDER NO CIRCUMSTANCES MUST A UM 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 overleaf.
A minimum 1 bar twin ended booster pump may be fitted with the mixer shower, but for improved performance,
we recommend a twin ended booster pump larger than 1 bar is used.
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.
CYLINDER TEM ERATURE IN EXCESS OF 65ºC MAY RESULT IN OOR SHOWER ERFORMANCE.
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 to suit the intended inlet connection fittings.
Siting
With boosted gravity fed systems, please ensure the minimum gravity flow rate is sufficient to operate the pump flow
switches.

If required, apply jointing tape to the threads and fit the eccentric elbow connectors
sufficiently to achieve a water tight seal, terminating at 150mm centres to suit the
exposed valve inlets.
7
Eccentric elbows are provided to allow for inlet pipework adjustment between 130mm – 170mm centres. Construct
suitable connections terminating in ½”BSP female fittings.
When using the eccentric elbows provided we recommend leaving sufficient threads from the finished wall
surface, after the cover plates have been fitted, to ensure adequate purchase for the exposed valve.
If using alternative fixings please refer to the installation instructions provided to ensure adequate threads are left
to connect the exposed valve after the cover plates have been fitted to the finished wall surface.
