easier and warmup quicker. See Figure 1 for heater kit
specifications.
The adhesive application of the oil pan heater allows for
a quick and easy installation. See Figure 2 for
illustrations of installed heater kits.

power source.
Supply a utility power source for the oil pan heater if one
is not already available. See the drawings supplied with
the generator set for conduit/stub--up locations.
For the 120 VAC kit, the oil pan heater cord plugs into a
120 VAC receptacle. For the 240 VAC kit, the oil pan
heater cord connects directly to a 240 VAC power
source.
Read the entire installation procedure before beginning

service.
1. Press the OFF button on the generator set
controller.
2. Disconnect the utility power to the generator set.
3. Disconnect the generator set engine starting
battery, negative (--) lead first.
1.2 Install the oil pan heater.

and clean the installation area with a non--oil based
solvent such as isopropyl alcohol or heptane.
5. Slowly peel the adhesive cover from the oil pan
heater.
6. Position and apply the heater pad to the bottom
surface of the oil pan.

(70_F and 100_F) when applied to the oil pan.
7. To ensure a good adhesive bond, use a heat gun to
warm the heater pad. Apply pressure evenly to
remove any air pockets.
Note: To prevent damage, the power cord must not
touch any heated surfaces or moving
components. Ensure adequate clearance from
hot surfaces or moving parts.
