ADVICE TO USERS

A

The electric heating elements operate at a
constant rate. It is the flow rate of the water
passing through the heater which determines the
water temperature – the slower the flow, the
hotter the water becomes and the faster the flow,
the cooler the water.

B The heater can provide sufficient hot water for
handwash purposes or low fill rates to a sink. If
connected to two taps, they should not be
operated simultaneously. During Winter, mains
cold water entering the unit will be cooler than in
Summer. Therefore the flow rate of hot water will
vary between seasons.

C Switch off immediately at the isolating switch if
water ceases to flow and contact Triton Customer
Service.

SAFETY WARNINGS

1

The heater MUST NOT be used if suspected of

being frozen.

2 Switch off immediately at isolating switch if
water ceases to flow during use.

3 If it is intended to operate the heater in areas of
hard water it is advisable to fit a scale inhibitor
(contact Triton for advice).

4 A thermal cut-out device is fitted to the
elements to protect the unit under faulty
conditions.
If cut-out operates, see ‘Operating Functions’
(overheat cut-out) or contact Triton Customer
Service for advice.
