If the operator is already installed it will be

necessary to take it down or the oil will run out and it
will be difficult to refill.

2)

Tilt the operator so that the hand-chain

housing is up and remove the drain plug adjacent to
the hand-chain housing (opposite the motor) from the
gear reducer. If any oil is lost replace it with an equal
amount of Mobil 1 or equivalent.

3)

Insert the heater plug into the oil drain hole

but do not tighten it at this time.

4)

Insert the immersion heater into the heater

plug as far as it will go. Tighten the heater plug. The
plug will close around the heater and hold it in place.

5)

a) On 120 Volt Operators connect the two

the two heater wires to the black and white (primary)
wires on the 50VA transformer included with the kit.
(Wire nut all other transformer wires)

6)

Be sure to route the heater wires away from

moving parts and the chain hoist mechanism.
Remember these wires carry 120 Volts.
