PIPING RECOMMENDATIONS
Fire and Ice portable chiller/heater
units are
built with glycol supply and return stainless-
steel manifolds fitted with male quick connect
fittings. One set of hoses with female quick
connect fittings are included. Additional hose
sets are available for purchase. Male quick
connects will be needed on tanks to connect
with hose set.
Confirm
tank jackets
have been flushed of any
debris before connecting FNI onto them for
the first time.
Individual
temperature control package
should be installed at each vessel to maintain
optimal conditions for each process being
heated or cooled by the Fire and Ice unit.
Glycol pressure is adjustable:
Verify tank jacket ratings before pressurizing piping
(bypass valve is pre set for 20PSI)

o
Bypass valve: Loosen packing nut and turn handwheel to adjust supply pressure
