GFH45-IOM Rev. 0 12/18 Printed in USA
INSTALLATION
CAUTION:
The regulator must be installed with the
draincock downward to allow accumulated fluid to
drain out when the draincock is opened.
CAUTION:
Moisture and particulates can be
discharged at high speed when draincock is
opened.
The GFH45 can be line mounted, panel mounted, or wall
mounted (reference G6018006 wall-mount bracket).
Teflon tape is the preferred thread sealant for the 1/4”
NPT connections.
Connect the supply to the port marked “IN”. The other
ports are outlet and factory plugged outlet gauge ports.
WARNING
: If the supply line is connected to the outlet
port, regulator damage or unexpected flow through the
regulator could occur.
Prior to applying inlet pressure, double check the
connections and assure the wrench knob or hand wheel
is backed out sufficiently to unload the range spring in
the bonnet.
Carefully apply inlet pressure and check the supply
connection for leakage. Adjust the output pressure by
rotating the wrench knob or hand wheel clockwise and
check the outlet connection for leakage.
WARNING:
The handwheel or wrench knob can vibrate
loose and fall out if the jam nut is not tightened.
