Plumbing – Typical layouts
Important installation notes :
• Avoid potential air traps in the pipe runs
• For loft installations ensure that there is no risk of freezing of the pipes and the unit, but do not
cover the base unit with loft insulation.
• The hot water supply to the base mixer unit must be set between 50°C - 65°C.
Low pressure (Gravity fed) systems (Pumped Model only)
Pumped Model only
Warning: Unit MUST NOT be connected to the mains water supply
(The cold and hot water MUST come from a gravity fed supply using the same header tank)
High pressure – Unvented mains fed storage (Non Pumped Model only)
•
Pressure reducing valves are required if the
pressure is above 5 bar.
•
This plumbing scheme requires that the hot
water pipe to the base unit (Non pumped
model) MUST come from an un-vented
stored hot water cylinder
•
The cold water supply MUST come from a
balanced pressurised supply.

•
The cold and hot water pipes to the
base unit (Pumped Model only)
MUST come from a gravity fed
(header tank) supply providing equal
pressures.

Maintenance
a) Cleaning the remote control and descaling the shower handset
While cleaning, isolate the power supply to the base unit.
• Clean the shower remote control using a soft cloth and avoid using abrasive or solvent based
cleaning fluid, especially on any plated finishes.
Warning : Never immerse the remote control in any liquid
Regularly inspect the hose for wear and damage. Replace if necessary, or every
two years, with an approved part.
To maintain performance, the shower handset
must be cleaned regularly.
• Clean the shower handset spray by rubbing the nozzles (a).
• Alternatively soak the shower spray handset in a proprietary
lime scale remover (b). (Rinse thoroughly after cleaning).
b) Cleaning the base unit inlet filters
If the flow rate is lower than normal, then the inlet filters may need to be cleaned.
(Separate filtered isolation valve available as an ancillary – See Page 19)
While removing and cleaning the inlet filters, isolate the power supply to the base unit.
• Turn off the cold water and hot water supply to the base unit.
• Remove the cold and hot water connections at the union with the base unit and carefully remove
the filters (as shown).
It may be necessary to re-prime the shower base unit after the filters have been cleaned. (Refer to
section "Bleed the air out of the base unit" on Page 10).
• Wash the filters thoroughly under running
water.
• Replace and reassembly the cold and hot
water connections.
• Turn water and electrical supplies back on
again.
