Section 8
Before using any fluid or performing maintenance where contact with the
fluid is likely refer to the manufacturer's MSDS for handling precautions.
Ensure the fluid is below the safe-handling temperature (below 40°C) before
draining the chiller.

There are two different types of drain port, a ¼" brass Male NPT pipe plug or a ¼"
MPT Riton fitting. If your
Position a suitable pan beneath the drain port at the rear of the chiller. The drain
pan must be shallow (under 3½" in height) and have a volume of approximately 3
gallons (6 gallons for ThermoFlex7500 - 10000). Remove the ¼" Male NPT pipe
plug from drain port or open the Riton fitting by turning either counter clock wise.
For ThermoFlex7500-10000, open the drain valve. This will drain the return line,
reservoir, plate exchanger, and the suction side of the pump.
To drain the discharge side of the pump disconnect the Female NPT outlet
connection on the rear of the chiller.
Note Internally the

discharge side however take care to contain what fluid does drain, a wet-vac can be
employed to minimize the potential for spillage.
If the chiller is equipped with the flow control or pressure relief with flow control
option, open the valve or remove the drain plug in order to drain the discharge
line, see Section 5.
If the chiller is equipped with the anti drainback option, use the controller's
SETTINGS menu to open the valve, see Section 4. Opening the valve allows the
fluid to drain out of the chiller.
Reinstall ¼" Male NPT pipe plug using a sealant suitable for the wetted materials or
close the Riton filling prior to refilling the chiller.
Do not overtighten the fitting.
For ThermoFlex7500-10000, close the drain valve.
