2. Insert replacement switch through panel from
which defective switch was removed. Insert name-
plate over toggle and secure to panel with nut sup-
plied with switch. Orient switch and tighten nut to
secure in desired position.
3. Plug in filter power cord and operate switch to verify
switch orientation corresponds to nameplate legend.
If not, loosen attaching nut and reorient nameplate
and/or switch as desired and retighten nut.
C. MELT CYCLE SENSOR
Removal:
1. Disconnect filter from electrical power source.
NOTE: Remove all oil from filter vessel. Filter must be
positioned on its end to access melt cycle sensor.
2. Raise front (power cord) end of filter and rest filter
on oil absorbing rags on its back end.
3. Remove bottom cover attaching screws; remove
bottom cover.
4. Remove electrical leads from defective melt cycle
sensor.
5. Loosen heater element cover attaching nut adja-
cent to melt cycle sensor sufficiently to release melt
cycle sensor and its retaining plate. Disengage melt
cycle sensor.
Replacement:
1. Orient replacement melt cycle sensor in its retain-
ing plate such that the metallic sensing surface will
be in direct contact with filter vessel. If necessary,
reverse orientation of retaining plate.
2. Position retaining plate under heater element and
tab on heater element cover with melt cycle sensor
sensing surface in direct contact with filter vessel.
Tighten loosened heater element attaching nut.
3. Attach removed electrical leads to melt cycle sen-
sor. Verify terminals are not in contact with any metal-
lic parts of filter vessel, heater cover or heater.
4. Secure bottom cover with removed attaching
screws.
5. Position filter right-side-up and clean up oil absorb-
ing rags.
D. HEATER ELEMENT(S)
Removal:
1. Disconnect filter from electrical power source.
NOTE: Remove all oil from filter vessel. Filter must be
positioned on its end to access heater element(s).
2. Raise front (power cord) end of filter and rest filter
on oil absorbing rags on its back end.
3. Remove bottom cover attaching screws; remove
bottom cover.
4. Remove electrical leads from defective heater
element(s). Tag leads as they are disconnected to as-
sure, during replacement, they are reconnected to the
proper terminals.
5. Loosen heater element(s) cover attaching nuts
sufficiently to release defective heater element(s).
Carefully remove heater element(s) being careful not
to dislodge cover insulator(s).
Replacement:
1. Carefully position replacement heater element(s)
between filter vessel and cover insulator(s).
2. Tighten loosened heater elements cover attaching
nuts to secure heater element(s) in position against
filter vessel.
3. Connect tagged electrical leads to heater
element(s).
4. Secure bottom cover with removed attaching
screws.
5. Position filter right-side-up and clean up oil absorb-
ing rags.
E. PUMP AND MOTOR
Removal:
1. Disconnect filter from electrical power source.
NOTE: Remove all oil from filter vessel. Filter must be
positioned on its end to access pump and motor.
2. Disconnect hand hose assembly from quick discon-
nect on discharge port on defective pump and motor.
3. Raise front (power cord) end of filter and rest filter
on oil absorbing rags on its back end. Remove bottom
cover.
4. Remove attaching screws securing front panel. Tilt
back front panel to expose pump and motor.
5. Remove motor junction box cover and remove elec-
trical leads from motor terminals. Tag leads as they
are disconnected to assure, during replacement, they
are reconnected to proper terminals.
6. Unscrew coupling nut securing suction tube under
filter vessel from plumbing connected to pump and
motor suction port. Oil absorbing rags should be avail-
able as some oil spillage should be expected.
7. While supporting pump and motor, remove attach-
ing nuts, flat washers and screws; remove pump and
motor. Note orientation of plumbing elbows at pump
suction port and then unscrew these parts.
8. Remove motor junction box cover and disconnect
electrical leads from motor terminals. Tag leads as
they are disconnected to assure, during replacement,
they are reconnected to the proper terminals.
