4.6 ANNUAL
Annual maintenance consists of post-operation, weekly, and monthly mainte-
nance. Maintenance for extreme conditions may also apply. In addition, the
annual maintenance includes the following tasks:
❑ Replacing the pump gearbox oil - see page 52. Also see Figure 4-1: “Gear-
box Oil Change Plugs” on page 50.
❑ Relief valve system, check and repair - see page 53.
❑ Checking individual drain lines from the pump to the multi-drain to ensure
proper drainage and protection from freezing - see page 54.
❑ Performance testing, including Test tank-to-pump flow rate - see page 54.
❑ Disassembly of priming pump to clean vanes - see page 54. (Also see sep-
arate manual provided.)
IIMPORTANT !
DO NO USE A LUBRICANT ON THE PRIMING PUMP VANES AND VANE SLOTS.
LUBRICANT AND COLD WATER FORM AN EVENTUAL GUMMY RESIDUE THAT
RENDERS THE PRIMING SYSTEM INOPERATIVE. A COMPLETE AND THOR-
OUGH DISASSEMBLY AND CLEANING IS THEN REQUIRED.
❑ Running the yearly pump test to check performance levels - see page 54.
(See NFPA 1911 standard for more details.)
Replace Gearbox Oil
1. Remove the drain plug (magnetic) and drain the gearbox oil into a suitable
container. For container size based on gearbox capacity, see “Appendix
C1: Lube and Sealant Specifications” on page 115. Also see Figure 4-1:
“Gearbox Oil Change Plugs” on page 50. Have clean disposable shop rags
and oil dry handy.
2. Examine the oil for contamination (e.g., water – turns the oil a milky color or
settles to the bottom). Also see Section 5 Troubleshooting, heading
“Water/Moisture in Pump Gearbox.” on page 65.
3. Properly dispose of the used oil.
4. Inspect the magnetic drain plug. If metal filings are present, remove the
cover plate to visually inspect and clean all internal components.
