the wiring diagram on the reverse of the inspection panel.
For indirect controls a 240V, 3 amp supply is required.
On Comfort models the indirect thermostat is factory fitted, for 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
