Operating Guide

NEVER OPERATE THE PUMP WITHOUT WATER. Water acts as a coolant and

lubricant for the mechanical shaft seal. NEVER run pump dry. Running pump dry may

damage seals, causing leakage, ooding, and voids warranty. Fill strainer housing with water before starting

motor.

Do NOT add chemicals to pool/spa system directly in front of pump suction. Adding

undiluted chemicals may damage pump and voids warranty.

Before removing strainer cover:

1. STOP PUMP before proceeding.

2. CLOSE VALVES in suction and outlet pipes.

3. RELEASE ALL PRESSURE from pump and piping system using lter manual air relief valve. See lter

owner’s manual for more details.

4. If water source is higher than the pump, pump will prime itself when suction and outlet valves are opened.

If water source is lower than the pump, unscrew and remove strainer cover; ll strainer housing with water.

5. Clean and lubricate strainer cover O-ring with silicone lubricant each time it is removed. Inspect O-ring and

re-install on strainer cover.

6. Replace strainer cover on strainer housing; turn strainer cover clockwise to tighten cover.

Before re-starting pump, see “Starting/Priming the Pump” instructions.

Wait ve (5) seconds before re-starting pump. Failure to do so may cause reverse

rotation of motor and consequent serious pump damage.

Turn on power and wait for pump to prime, which may take up to ve (5) minutes. Priming time will depend on

vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime within ve minutes,

stop motor and determine cause. Be sure all suction and discharge valves are open when pump is running.

See Troubleshooting Guide.

MAINTENANCE

• Clean strainer basket regularly. Do NOT strike basket to clean. Inspect strainer cover gasket regularly and

replace as necessary.

• Star pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary.

• Keep motor clean. Ensure air vents are free from obstruction to avoid damage. Do NOT use water to hose

o󰀨 motor.

• Occasionally, shaft seals must be replaced, due to wear or damage. Replace with genuine Star seal

assembly kit. See “Shaft Seal Change Instructions” in this manual.

Separation Hazard. Do not purge the system with compressed air. Purging the system

with compressed air can cause components to explode, with risk of severe injury or death

to anyone nearby. Use only a low pressure (below 5 PSI), high volume blower when air purging the pump,

lter, or piping.

Allowing the pump to freeze will void the warranty.

Use ONLY propylene glycol as antifreeze in your pool/spa system. Propylene glycol is

non-toxic and will not damage plastic system components. Other anti-freezes are highly

toxic and may damage plastic components in the system.

Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long

time (see instructions below).

Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do NOT cover or wrap

pump with plastic lm or bags.
