MAINTENANCE/SERVICE
Every 6 months:
Test relief valve system for proper operation.
If operation is sluggish, check the pencil strainers in discharge and suction at the top of the pump. Clean or
replace if clogged.
Check all tubing, connections and fittings for leaks. Tighten or replace as required.
Check panel light bulb, replace if burned out. The bulb is a No. 1891, Hale Part No. 200-0540-02-0.
Lubricate the PMD control as outlined under “MAINTENANCE” on Plate No. 742C.
HYDROSTATIC TEST NOTE
NFPA 1901 requires a hydrostatic test of 250 psig on the pump and related piping at the time the truck is
delivered. To accomplish this with the TPM system requires that you remove the pencil strainer in the pump
suction marked “vacuum” and temporarily install a 1/4” NPT pipe plug for the hydrostatic test. In addition,
you must turn the PMD control handwheel clockwise all the way to the highest pressure to “lock it out”. After
the hydrostatic test, return the PMD control back to its normal setting and reinstall the pencil strainer and line
to the sensing valve.
If you do not disconnect the strainer and lock-out the PMD control valve, water will leak into the tank and the
PG30 relief valve will open dumping water on the ground, making a hydrostatic test impossible.
Replacement Parts:
Replacement Part Numbers are called out on Plate No. 742C (attached). To order parts, contact Hale Fire Pump
