Opto thermostatic valves provide close temperature stability and fail safe protection on appropriate high and low pressure systems.
For optimum performance the Opto product range has been designed to suit each specific water system. Please refer to the product
specification section below.
The Opto range is supplied with a 2 year comprehensive guarantee. In the event of any product problems, please contact the
Aqualisa customer helpline on 01959 560010.
Safety information
This product must be installed by a competent person in accordance with all relevant current Water Supply Regulations.
Opto is designed for domestic use only.
Product specification
Low pressure systems (gravity), systems beginning with the prefix OPG – incorporate a thermostatic cartridge part number 022809,
identified by an ORANGE ring on the face of the concealed valve cartridge and an ORANGE band on the temperature side of the
surface mounted valve cartridge assembly, part number 265509. Product is suitable for gravity stored systems. Pressure range
0.1 – 10.0 bar max (static).

number 022802, identified by a PINK ring on the face of the concealed valve cartridge and a PINK band on the temperature side of
the surface mounted valve cartridge assembly, part number 265502.
The Opto systems suitable for combination boilers are designed to give optimum temperature control and stability from fully
modulating combination boilers and instantaneous gas water heaters. As assembled, a YELLOW flow regulator is fitted into the hot
entry of the ‘cartridge’ to meet the performance requirements of an 80,000 Btu appliance. For appliances of a higher rating, the
regulator must be replaced in accordance with the table below:
100,000 Btu = OLIVE regulator
120,000 Btu = BLUE regulator
DO NOT CONNECT THIS PRODUCT TO AN APPLIANCE RATED AT LESS THAN 80,000 BTU.
Please refer to the flow regulator fitting instructions on pages 8 & 12 if the replacement of the factory fitted regulator
is necessary.
High pressure systems, systems beginning with the prefix OPH – incorporate a thermostatic cartridge part number 022803, identified
by an GREEN ring on the face of the concealed valve cartridge and an GREEN band on the temperature side of the surface mounted
valve cartridge assembly, part number 265501. Product is suitable for balanced high pressure systems e.g. unvented storage etc.
Pressure range 2.0 – 10.0 bar max (static).
Connections
The Opto shower range incorporates ‘push fit’ type connections for use with 15mm British Standard copper tube. Tube should be cut
with a rotary type cutter and lubricated using a silicone based lubricant or petroleum jelly (Vaseline or similar) prior to insertion into
the fitting. If a hacksaw is used, the pipe ends must be thoroughly deburred and chamfered prior to insertion to the product.
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.
The Opto shower range is designed for conventional supplies with HOT on the LEFT and COLD on the RIGHT as viewed from the
front. However, built in Opto may be adapted for use with reversed supplies. Please refer to the reversed supplies fitting instructions
on page 19. Surface mounted Opto 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 on page 19.
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 through in accordance with current Water Supply Regulations prior to connection of
the product.
Important information

Filters
To ensure optimum ongoing performance, the ‘CARTRIDGE’ control mechanism is protected by a two part filter system in the
internal waterways. Debris accumulation may result in progressively reduced flow through the showerhead and noisy operation.
As this condition is not covered by our standard warranty terms, it is suggested that the cartridge is removed and the filters checked
by a competent person. In the event of any difficulties please contact the Aqualisa customer helpline for assistance.
Isolating valves
Suitable isolation valves such as gate 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 or pumped installations.
Pressures
Opto shower valves are 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.
Opto shower valves are not suitable for mixed supply systems e.g. Gravity hot and mains cold.
Gravity systems
Services must be installed according to good plumbing practice having regard to pipe sizing, long pipe runs and low-head situations.
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 65ºC 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.
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 layout on page 20.
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 page 20.
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.

6
Balanced high pressure system
The high pressure Opto cartridge (GREEN) 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 21.
Combination boiler/multipoint system
This product MUST NOT be fitted to an appliance rated at less than 80,000 Btu.
The Opto 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.
For optimum performance the Opto product specifically for combination boiler systems is supplied with flow regulators to control the
incoming hot water pressure into the cartridge. The Opto combination boiler cartridge (PINK) is factory fitted with a YELLOW
regulator suitable for an 80,000 Btu boiler. The regulator should be changed to suit the relevant rated boiler as listed below:
YELLOW = 80,000 Btu boiler
OLIVE = 100,000 Btu boiler
BLUE = 120,000 Btu boiler
Please refer to pages 8 & 12 for changing the regulator instructions.
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 21.
