Xentherm Fluid Replacement Procedure
WARNING: DO NOT ATTEMPT TO DRAIN THE XENTHERM
FLUID IF THE SYSTEM IS ABOVE 110F, SERIOUS BODILY
INJURY COULD RESULT
1) Open the purge valve located on the top of the 3/4"ball valve that is located
on the top of the upper Xentherm heat exchanger. (See Figure 1)
2) Slowly open the
3/4‖ b
all valve, to relieve any air and gas pressure.
3) When all air and gas pressure has been evacuated, remove the purge valve-
3/4‖ b
all valve assembly as one unit by removing the hex fitting that is
threaded into the upper Xentherm heat exchanger.
4) Using a suitable container (3 gallon or more), remove the drain plug from the
lower Xentherm heat exchanger. Allow all oil to drain before proceeding.
Re-install the drain plug using High Temperature sealant P/N 13-001 or
equivalent.
5) Remove the vent plug from the lower Xentherm heat exchanger.
Slowly begin filling the the lower system through the UPPER
Xentherm heat exchanger through the threaded port where the purge
valve-
3/4‖ b
all valve assembly was removed in step 3, until the fluid
level reaches the vent port on the LOWER Xentherm heat exchanger.
NOTE: It will take approximately one to one and one half (1
to 1 1/2) gallon(s) to fill the lower Xentherm heat exchanger.
7) Re-install the vent plug in the LOWER Xentherm heat exchanger using High
Temperature sealant P/N 13-001 or equivalent.
8) Continue to fill the system from the UPPER Xentherm heat exchanger until
the sight glass is 1/2 to 3/4 full. (See Figure 2) Re-install the purge valve-
3/4‖
ball valve assembly.
9)
NOTE: DO NOT HEAT THE FLUID Ensure that the Digital
Temperature Control is adjusted to 50F or less, engage the PTO and then
engage the water pump. Run the unit at idle for 3 minutes, turn off the water
pump and shut down the unit; check the fluid level and fill as necessary.
10)
Re-install the purge valve-
3/4‖ b
all valve assembly using High Temperature
sealant P/N 13-001 or equivalent.
