To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer
baskets regularly.
It is important to visually inspect the basket, through the see through lid, at least once a week. A dirty basket
will reduce the efficiency of your system, and can put an abnormal load on the pump which could result in
costly repair bills.
C. All Models.
1. DO NOT RUN PUMP DRY. If pump is run dry, the mechanical seal will be damaged and external
leakage will occur. When this happens, the damaged seal must be replaced.
2. ALWAYS MAINTAIN PROPER WATER LEVEL in the pool or spa - half way up the skimmer
opening - or at least four inches above the suction fittings if no skimmer is installed.
Jetted tub - at least one inch above the highest jet.
If water level falls below the skimmer opening or suction fittings, the pump will draw air, causing the
pump to run dry, resulting in a damaged seal.
Continued operation in this manner could result in damage to the pump case and impeller.
D. Shaft Seal - (Rotary Seal).
1. The shaft seal consists of two parts:
a. Rotating ceramic seal, pressed fit into the impeller.
b. A stationary spring loaded seal, press fitted into the rear of the volute.
The highly polished and lapped faces of the seal are easily damaged. Handle with care. This centrifugal pump requires
little or no service, however, the shaft seal will wear with normal use over the years, and will require periodic
replacement.
E. Electric Motor.
1. The electric motor should be protected from foreign matter, water splashing, hosing and the weather.
Enclosures should be well ventilated to prevent overheating. If a motor becomes wet, permit it to dry
before running it. If a motor has been damaged by water or dirt, the warranty is voided.
2. The motors used on Maxim pumps are 48 frame–through bolt motors. The through bolts are used to
secure the volute to the motor. When replacing motor, mark the end bells and the motor shell to indicate
alignment. Remove the four nuts from the through bolts - at shaft end. Place shaft through back of volute
and locate through bolts in line with brass inserts located in four legs at rear of volute. Be sure the end
bell and shell marking line up. Securely fasten the motor to the volute.
3. Protect the motor from heat.
a. Avoid direct sunlight.
b. Provide ample ventilation.
4. Protect the motor from dirt.
a. Keep the motor, vents and surrounding area clean.
b. Avoid sweeping or stirring up dust near the motor while it is running.
c. Avoid stirring (or spilling) water chemicals near the motor.
