A mold purge valve is available as an option. This valve quickly evacuates fluid from the
process circuit, allowing faster disconnection of the temperature controller from molds
and hoses. A manual purge button controls this valve.
If this option is ordered with the Thermolator, purge control wiring and installation of
the valve on the process line outlet of the unit is completed at the factory. You still must
connect process and cooling water inlets and outlets, as well as supply of non-lubricated
compressed air.
1
Remove the shipping pipe plug from the female connections on the back of the
Thermolator.
2
Install an external ball valve on the cooling water inlet of the Thermolator. This
valve is required when a purge valve is used.
3
Install pipe to the rear of the Thermolator. Use male 1
process connections and male 1-inch NPT piping for water connections. Pipe and
pipe threads must be clean and new. Clean threads with solvent, removing all oil,
grease and dirt. Allow the threads to dry before proceeding.
4
Coat the pipe threads with thread sealant. Follow the sealant manufacturer's
directions.
5
Connect the male pipe to the appropriate female connection on the back of the
unit. Connect cooling water lines as indicated on the previous page. Connect process
lines as indicated below. Start by hand until the threads engage, then use a pipe
wrench to tighten the connection only enough to prevent leaks. Do not over-tighten!
6
Connect the purge valve to the compressed air supply. The air pressure should not
exceed 100 psi.

TIP: Conair recommends or-
dering the purge valve with the
Thermolator so that wiring and
installation is completed at the
factory. However, aftermarket
addition of the purge valve is
possible.
