Location
The appliance must be installed in a frost
free environment.
In order to minimise distribution losses the
distance between the appliance and the
outlet fitting should be as short as possible
(less than 2m).
Plumbing
The appliance is intended for connection to
a mains potable water supply. The specific
water resistance of the supply must not
fall below the minimum specified on the
rating plate.
Minimum flow requirements:
2 litres/min.
Should be installed by a suitably qualified
person.
N.B. Not recommended for use with
thermostatic mixing valves or taps.
Electrical
The appliance must be earthed and
connected to the supply by means of
permanent wiring through an isolation
switch having a contact separation of at
least 3mm on all poles and protected by a
suitably rated circuit breaker.
The cross sectional area of the connection
cable must be in accordance with the power
rating of the appliance.
The installation must be in accordance with
current IEE regulations.
* Subject to a minimum water pressure of 2 bar and maximum of 10 bar
