Drain Lines:
The following drains should be installed if the truck will see freezing temperatures. Do not connect any of
these drains to a ganged or multi-drain valve Each line must have a separate drain valve or the TPM system
will not operate properly.
Install a drain line in the bottom of the QG relief valve by removing the red cap plug and running a line to a
panel drain valve.
Install a drain line in the sensing valve port marked “D”, by removing the red cap plug and running a line
to a panel drain valve.
Install a tee in the sensing valve port marked “A”, with one leg of the tee going to the top of the water tank
and the other leg to a panel mounted drain valve. If the pump will never be kept as a “wet pump”, then the
line from port “A” may go to atmosphere.
Relief Valve Plumbing:
Attach a 3” pipe to the discharge outlet flange of the PG30 relief valve. This pipe is to direct the water to the
ground in a direction that will not get the operator wet (toward the back of the truck). Do not restrict this pipe
with any smaller piping or fittings. Remember that over 1000 gallons per minute may flow through it, so it
must be properly supported through its entire length and capable of withstanding the reaction force from the
flowing water.
Electrical Connections:
All wiring should be done in accordance with NFPA specifications. Do not use smaller than 16 gauge for these
connections. All Hale switches have .156” diameter female receptacle snap connections, use .156” male snap
plugs to connect. (Reference Plate No. 743C).
Run one wire from the battery (+) to one of the QG relief valve switch leads located in the center of the
cover, using a snap connector.
Run one wire from the other QG relief valve switch lead using a snap connector, to the indicator light on
the PMD Control Instruction Plate mounted on the pump panel using a ring terminal.
Run one wire from the other indicator light connection using a ring terminal to the red wire lead on the
switch/flasher unit located on the switch guard (019-0110-00-0) on the PG30 relief valve, using a snap
connector.
Run one wire from the other lead on the PG30 switch/flasher unit using a snap connector to a convenient
ground (-).
