Centre-to-centre distance X minimum = 100 + immersion heater diameter.

Mounting
Immersion heaters must be fixed through to the lid of the furnace or its walls.
The immersion heater installation must allow compliance with the following temperatures during operation:

Connections
We offer two types of connector:
- Quick plug, “Harting” type or equivalent

- Connection by terminal/cable lugs and cable gland fitting
Connection with quick plug
The male socket delivered fitted to the immersion heater is pre-wired and no intervention is required.
Direct connection to terminal block via cable gland fitting

Removing the head:
The head has to be removed to be able to connect to the immersion heaters through the cable gland fitting. The
plastic plug delivered fitted to the head should be replaced by a gland fitting PG21 (immersion heaters ø28 and
32) or PG36 (immersion heater ø55).

Connecting the power cable (not supplied by ATHERM):
The power cable is dimensioned based on the amperage required for the immersion heater to operate.

Thread the power cable through the cable gland fitting.
Remove the first nut from terminals U1, V1 and W1 and connect the power cable lugs. Retighten the nuts to a
max. torque of 3 Nm.
