Installation
General Guide
For your safety this installation should be completed by qualified
personnel complying with all relevant regulations and byelaws.
Chiltern Invadex Shower cubicles are manufactured to many different
specifications and sizes. It is therefore important that all services
relevant to your model are complete and tested before you attempt to
assemble your shower cubicle. All building work and decorating should
be finished i.e. a suitable floor in place, skirting boards painted and fixed,
walls and ceilings plastered and decorated.
Check all the items in the carton against the parts list on the
enclosed leaflet.
Should you require any technical assistance or have any queries
regarding installation procedures contact your nearest Chiltern Invadex
Office. For an efficient response it will help if you have the model type
and serial number to hand when you call (the serial number can be found
on the label on the back panel).
Services - Incoming Water
The installation must be in accordance with local water company
byelaws.
Mixer showers
Both hot and cold supplies must come from the water storage tanks with
at least 2 metres head of water above the shower.
BOOSTER PUMP If the required head of water is not available a Twin
Impeller Booster Pump can be employed. Do not use flow switches.
All supplies should terminate close to the relevant controls with a 3/4" B.
S. Male outlet. We strongly recommend that accessible isolating valves
are fitted near to our units to facilitate future servicing, or isolation, in the
event of an emergency.
Instantantaneous Shower
15mm pipe with mains cold water supply.
Minimum operating pressure 1 bar (14.5 p.s.i.).
Permissible pressure variations 1 bar - 10 bar (14.5 p.s.i. - 145 p.s.i.).
Waste Water (fig 1)
The Chiltern Invadex Shower has a 12 volt pump positioned in the rear
left hand corner of the cabinet. It pumps the waste water out of the base
to a waste stack similar to that used by a washing machine.
The waste stack need only be in 1 1/4" (32mm) plastic but it is necessary
to fit a trap to prevent odours.

The height of the waste stack should be between 508mm and 711mm
above the floor level and fitted to the left hand rear of the proposed
shower position (see diagram). This diagram is only one example of an
installation. The position of the pipework will vary according to individual
situations. NOTE: The lower the waste stack pipe the less water will be
left in the trough once the pump is turned off.

All installations must comply with I.E.E. regulations, Local Authority
bylaws and electricity board regulations and must be carried out only by
a qualified electrician.
Follow manufacturers instructions for installation of the shower heater
unit for all electrical units.
SUGGESTED WIRING METHOD
Run a suitable cable (6-10mm sqr for electric showers depending on power
rating and supply distance) from the consumer box via 30mA RCD to the
Double pole ceiling pull switch in the wiring block supplied. (This switch is
used to isolate the shower as well as turning the shower waste pump on
and off and must be accessible to a wheelchair user where applicable).
The wiring block is positioned at a maximum of 4m from the pump unit and
complies with all mentioned regulations. Follow connection instructions
included with wiring block to complete electrical supply.

Cleaning & Maintenance
Regular
Shower Cubicles do not require any major maintenance, but you should
follow these simple instructions:
Tray and Enclosure
To retain the surface quality of your shower cubicle, weekly
cleaning using bathroom cleaning mousse or washing-up liquid,
warm water and a soft cloth is recommended. For the slip resistant
shower tray area you may need to use a stiff brush. Stubborn stains
may require a non-scratch liquid cleaner.
Do not use oven cleaner or a scouring powder on any of the
surfaces. Use of scourers will dull the finish of the surfaces and
spoil the appearance of your tray and enclosure.
Shower Head (Handset)
If you live in a ‘hard-water’ area, the holes in the shower head will
block more quickly. This will result in a poor spray and a reduction
in the heating ability of some instant water heaters.
Remove rings from the shower head and vigorously scrape out the
scale in the grooves, ensuring that the holes are clear.
Monthly
Pump Maintenance (for trays with pumped waste)
Regularly (monthly) lift pump from the socket in the base and remove
foreign matter from the blades. Scrub the area around the pump with a
long handled stiff brush. This will reduce the build up of scum and
odours. Check that the small bore hole adjacent to the pump blades is
clean. Replace pump cover making sure that the pump cover touches the
shower base.
For performance
regularly clean pump
and shower head.
Annual
We recommend that the unit is serviced by a qualified Chiltern Invadex
engineer. This will ensure that the unit complies with current health and
safety regulations.

above the floor level and fitted to the left hand rear of the proposed
shower position (see diagram). This diagram is only one example of an
installation. The position of the pipework will vary according to individual
situations. NOTE: The lower the waste stack pipe the less water will be
left in the trough once the pump is turned off.

Installation
General Guide
For your safety this installation should be completed by qualified
personnel complying with all relevant regulations and byelaws.
Chiltern Invadex Shower cubicles are manufactured to many different
specifications and sizes. It is therefore important that all services
relevant to your model are complete and tested before you attempt to
assemble your shower cubicle. All building work and decorating should
be finished i.e. a suitable floor in place, skirting boards painted and fixed,
walls and ceilings plastered and decorated.
Check all the items in the carton against the parts list on the
enclosed leaflet.
Should you require any technical assistance or have any queries
regarding installation procedures contact your nearest Chiltern Invadex
Office. For an efficient response it will help if you have the model type
and serial number to hand when you call (the serial number can be found
on the label on the back panel).
Services - Incoming Water
The installation must be in accordance with local water company
byelaws.
Mixer showers
Both hot and cold supplies must come from the water storage tanks with
at least 2 metres head of water above the shower.
BOOSTER PUMP If the required head of water is not available a Twin
Impeller Booster Pump can be employed. Do not use flow switches.
All supplies should terminate close to the relevant controls with a 3/4" B.
S. Male outlet. We strongly recommend that accessible isolating valves
are fitted near to our units to facilitate future servicing, or isolation, in the
event of an emergency.
Instantantaneous Shower
15mm pipe with mains cold water supply.
Minimum operating pressure 1 bar (14.5 p.s.i.).
Permissible pressure variations 1 bar - 10 bar (14.5 p.s.i. - 145 p.s.i.).
Waste Water (fig 1)
The Chiltern Invadex Shower has a 12 volt pump positioned in the rear
left hand corner of the cabinet. It pumps the waste water out of the base
to a waste stack similar to that used by a washing machine.
The waste stack need only be in 1 1/4" (32mm) plastic but it is necessary
to fit a trap to prevent odours.
