External Fittings

Install G 1/4 BSPP threaded fittings you 
have purchased into the “Inlet” and “Outlet” 
ports. It’s recommended to hand-tighten 
all fittings to avoid damaging the cooling 
unit.

Parallel threads seal at their o-ring. Do 
not use any plumber’s tape or putty on 
the threads, which can interfere with  the 
o-ring seal.

Leave the “Drain” plug installed. This is only 
opened when emptying coolant.
