INSTALLATION General Do not take risks with plumbing or electrical equipment. Do not install the shower unit in a position where it could become frozen. Isolate electrical and water supplies before proceeding with the installation of the shower unit. The shower unit must be fed from a cold water storage cistern and hot water cylinder with equal pressures.
Page 11
Plumbing A minimum storage capacity of cold water of 230 litres (50 gallons) is required to provide adequate showering time. Insufficient storage may result in the pump being run dry. Layout and sizing of pipework must be such that nominally equal inlet supply pressures are achieved and the effects on the shower performance of other draw-offs are minimised. Make sure the shower unit is the first draw-off from the water supply. Avoid routing the high level hot feed pipe upward to the same level as the cold tank e.g.

Warning! Do not fix the shower unit to the wall until plumbing and electrical installations have been completed. Decide on a suitable location for the shower unit avoiding buried cables and pipes. The unit should be positioned at a height convenient for all the family (at least 200 mm below the ceiling to allow for the fitting and removal of the unit cover).

Make sure that the end of the supply Chamfer pipework is cut squarely and is free from burrs, which will damage the inlet manifold seals. Chamfer the end of the pipe to assist insertion into the fitting and prevent the ‘O’ seal tearing. Warning! Do not insert fingers into the push-fit connectors as this can result in injury.

Temporarily locate the shower unit. Position the shower unit on the wall and mark the three fixing points. Note! Installers may wish to obtain alternative proprietary cavity fixings for dry lined, stud partition or dry partition wall structures. 9. Use the push-fit release tool to push the grey collars into the manifold to release the shower unit from the supply pipes.

12. Fit the three rubber feet into the Rubber Feet recesses in the rear of the case as shown. The feet will reduce the noise transmitted by the power shower through the wall. Warning! Blanking plates should be fitted to stop water ingress into the inside of the unit. 13.

COMMISSIONING The unit must not be run dry. Before proceeding any further with the installation the shower unit must be commissioned. 1. Connect the flexible hose to the outlet of the shower unit. Hose Washer Caution! Do not over tighten. Hose Turn on the water supplies and check for leaks.
OPERATION Warning! The shower is a manual mixing shower which can select water temperatures from FULL HOT to FULL COLD. If the temperature control knob is turned anticlockwise fully the shower will deliver water at the same temperature as the stored hot water temperature (this will be the same temperature as the hot tap water temperature).
FAULT DIAGNOSIS Fault Diagnosis - User Maintenance The appliance is fully performance tested after assembly. Providing it has been correctly installed and is operated as advised, difficulties should not arise. In the unlikely event that you experience problems with your appliance then the following procedure will enable you to undertake basic fault finding before contacting the person responsible for installing your shower.

Fault Diagnosis - Installer Maintenance The Manual Power Shower is one part of an entire plumbing system. The fitting of a pump places additional requirements on the plumbing system. Some systems may require plumbing modifications to allow them to cope with higher flow rates. Providing the Manual Power Shower has been correctly installed and is operated as advised, difficulties should not arise. Fault diagnosis and maintenance must be carried out by a competent person for whom the fault diagnosis table is provided. In the event of any of the following tests failing, re-check as appropriate before contacting the Customer Support Department, (refer to the Back Cover).
