The chiller process inlets and outlets must be connected to the
plumbing that will circulate the temperature-controlled water
or fluid through the process. Cooling water inlets and outlets
are connected to the cooling water supply.
Remove the shipping pipe plug from the female
connections on the back of the chiller.
Install pipe to the rear of the chiller.
Use appropriately sized male NPT piping for the process
connections and the MPW condenser 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.
Coat the pipe threads with thread sealant.
Follow the sealant manufacturer’s directions.
Connect the male pipe to the appropriate
female connection on the back of the unit
.
Connections are labeled on the chiller. 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!
