Page 20

Your Stainless Lite unvented cylinder is automatic in normal use, but requires routine
maintenance which is normally carried out at least annually along with the boiler
service. The maintenance must be carried out by a suitably competent tradesperson
who is qualifi ed to work on unvented cylinders. The checks/work needed are listed
in the maintenance part of these Instructions.

The temperature of the hot water is adjustable, but the control thermostat should
have been set to 60˚C to meet the relevant regulations/ensure safe operation. In the
direct pattern, the control thermostat is part of the immersion heater and should only
be adjusted by a suitably competent tradesperson. A simple, manually adjustable
control thermostat is fi tted to the indirect pattern units, but it is recommended that
this is left at 60˚C as hotter water will increase the risk of scalding.

When initially opening the taps, a small surge in fl ow may be experienced, which
disappears as the pressure in the system stabilises. This is quite normal with these
types of systems and does not indicate a fault.

In some areas the water will initially appear cloudy, but will quickly clear when left to
stand. This is nothing to be concerned about and is due to aeration of the water.

WARNING - If water is seen fl owing through the tundish, this indicates a fault condition
which needs action.

If the discharge is hot and continuous, turn the boiler and/or the immersion heaters
off, but do not turn off the cold water to the appliance until the discharge is cold. Note:
The discharge may stop by itself as the discharge cools.

If the discharge is cold and intermittent, no immediate action is needed but this
indicates a problem with the expansion vessel.

However, in both cases you must call the registered installer / a suitably qualifi ed,
competent tradesperson, advise them that you have an unvented cylinder and
request a maintenance visit.

DO NOT, at any time, tamper in any way with the safety valves or overheat thermostats/
wiring.
