per.
1. Remove plug (28) from side of hopper (D).
2. Apply thread sealant to immersion heater threads
(L) and screw immersion heater into hopper (D).
3. After installation, remove plug (28) from opposite
side and verify element end is visible through plug
hole.
4. Install bushing (302) in top of wiring outlet. Route
power cable (303) through bushing (302).
5. Remove screws (HS) and immersion heater cover
(HC).
6. Connect white and black wires from cable (303) to
white wires inside immersion heater box. Tighten

The immersion heater (L) is only approved for
non-explosive atmosphere applications. Using the
immersion heater in hazardous locations, or explosive
atmospheres, may cause ignition or explosion.
• For hazardous environments use the Hopper or
Hose Heat Circulation Kit 256273; see manual
312359.
• Ensure the outer cavity of the hopper is empty
before installing immersion heater to prevent oil or
water mixture from exiting hopper.
NOTICE
Vertically orientate wiring outlet. Ensure bushing (302)
is positioned on top of the immersion heater (L) before
installing the cover (HC). Failing to do so will allow over-
heating, and therefore the overtemperature switch will
trip.
Do not bend heating elements during installation. Bent
elements may cause hopper wall failure allowing spray
material to contact heater.
