Technical information
INDIRECT SYSTEMS
For models up to 300 litres a mains supply of 240V, 3kW (13 amps) will be
required for the direct immersion heater. heat resistant cable, round 3 core
2.5mm
2
(to BS) must be used. For High Capacity 500 litre models consult
the wiring diagram on the reverse of the inspection panel.
For indirect controls a 240V, 3 amp supply is required.
On Contract and High Capacity models it is necessary to fit the thermostat
using P.T.F.E tape (Please consult the label on the face of the unit for the
correct location in both cases).
The cables must be clamped in position (as previously stated) and the
control thermostat should be set at 60°C for the reasons above. In addition
to the thermostat there is a thermal cut-out should the thermostat fail. Refer
to
FIG. 2.14.
