REPLACEMENT PROCEDURES 5-10 Manual 0-2728
I. Flow Switch Assembly (FS1) Replacement
1. Remove the Right Side Panel per Section 5.04-A.
CAUTION
Handle and dispose of the used coolant per recom-
mended procedures.
2. Partially drain the coolant from the Coolant Res-
ervoir until the coolant level is below where the
Flow Switch connects to the Reservoir. Drain cool-
ant as follows:
a. Disconnect the Reservoir to Coolant Filter As-
sembly hose at the Coolant Filter Assembly.
b. Place the end of the hose into a container to
catch the coolant as it flows from the reser-
voir. Drain enough coolant so that the coolant
level is below the Flow Switch Assembly con-
nection to the reservoir tank.
NOTE
Do Not run the pump as the coolant will gravity
feed from the reservoir.
3. Detach red wires at top end of Flow Switch where
they connect to wire harness.
4. Disconnect In-Line Coolant Filter from the bot-
tom of Flow Switch Assembly.
NOTE
Some residual coolant will drain from the In-Line
Filter. It is recommended that a rag or towels be
placed below the hose prior to removing.
5. Remove fitting from bottom end of Flow Switch
Assembly.
6. Disconnect Flow Switch from Reservoir and re-
move Switch from unit.
7. Install the replacement Flow Switch Assembly by
reversing the above steps, keeping in mind the
following:
a. The Flow Switch Assembly should be installed
at a slight angle to allow room for hose attach-
ment with the filter pointing away from the
tank.
b. Use thread sealant on all the pipe threads
when reinstalling.
8. Refill the Coolant Reservoir to the full level (refer
to label on coolant tank) with either the coolant
that was removed or add fresh Thermal Arc Torch
Coolant.
J. Output Inductor Assembly (L1 & L2)
Replacement
NOTES
There are two Output Inductors in this unit. Re-
placement instructions are the same for both.
The Output Inductor(s) are located behind the
Reservoir panel. To gain access to the Output
Inductor(s), the rear panel of the unit must be re-
moved, then the internal reservoir panel is disen-
gaged and moved out of the way.
1. Remove the Left and Right Side Panels per Sec-
tion 5.04-A.
2. Drain the coolant from the Coolant Reservoir as
follows:
a. Remove Reservoir Cap from Reservoir.
b. Disconnect the Coolant Supply Hose input
connection at the Coolant Filter Assembly. The
hose goes from the Coolant Filter Assembly
to the bottom of the reservoir.
c. Place the end of the hose into a container to
catch the coolant as it flows from the reser-
voir.
NOTE
Do Not run the pump as the coolant will gravity
feed from the reservoir.
3. Disconnect the Coolant Supply Hose output con-
nection from the bottom of the reservoir.
4. Disconnect the In-Line Filter Assembly where it
connects to the reservoir.
NOTE
Some residual coolant may drain from the In-Line
Filter. It is recommended that a rag or towels be
placed below the hose prior to removing.
5. Disconnect two air lines where they connect to
the two solenoid assemblies.
6. Remove the two bottom screws on rear panel.
7. Remove the two nuts and washers on the inside
of rear panel connecting the panel to the center
chassis.
8. Remove the rear panel from the unit by remov-
ing the screw located in the center of the rear panel
which secures the rear panel to the reservoir panel.
9. Carefully slide the rear panel out and away from
the unit.
