MAINTENANCE
DO NOT open the strainer pot if the IntelliPro
water in the strainer pot. Pumps operated in these circumstances may experience a build up of vapor pressure and may contain
scalding hot water. Opening the pump may cause serious personal injury. In order to avoid the possibility of personal injury, be sure
the suction and discharge valves are open and strainer pot temperature is cool to touch, then open with extreme caution.
To prevent damage to the pump and for proper operation of the system, clean pump strainer and skimmer baskets regularly.
Pump Strainer Basket
The strainer basket (or 'strainer pot'), is located in front of
the pump housing. The strainer basket must be kept clean
and free of debris. Inspect basket through the lid on the
top of the housing. Be sure to visually inspect the strainer
basket at least once a week. Dirty strainer baskets reduce
filter and heater efficiency and put abnormal stress on
the pump motor.
Cleaning the Pump Strainer Basket
1. Press Start/Stop button on the pump and turn
off the pump at the circuit breaker. Disconnect
communication cable from pump.
2. Relieve pressure in the system.
3. Turn the lid and locking ring counter-clockwise and
remove from the pump.
4. Remove debris and rinse out the basket. Replace
the basket if it is cracked.
5. Put the basket back into the housing. Be sure to align
the notch in the bottom of the basket with the rib in
the bottom of the volute.
6. Fill the pump pot and volute up to the inlet port with
water.
7. Clean the lid and locking ring, O-ring, and sealing
surface of the pump pot.
Note: It is important to keep the lid O-ring clean and
well lubricated.
8. Reinstall the lid by placing the locking ring and lid on
the pot. Be sure the lid O-ring is properly placed.
Seat the locking ring and lid on the pump then turn
clockwise until the locking ring handles are horizontal.
9. Turn the power "ON" at the circuit breaker. Reconnect
communication cable from pump.
10. Open the manual air relief valve on the top of the
filter. Stand clear of the filter.
11. Wait until all pressure is relieved. Start the pump.
12. Bleed air from the filter until a steady stream of
water comes out of the filter air relief valve. Close
the manual air relief valve.
THIS SYSTEM OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system (e.g., Lock Ring,
Pump, Filter, Valves, etc.) is serviced, air can enter the
system and become pressurized. Pressurized air can
cause the lid to separate which can result in serious
injury, death, or property damage.
To avoid this potential hazard, follow above instructions.

Winterizing
To protect the pump electronics from freeze damage,
the pump will switch on to generate internal heat as the
temperature drops below freezing. The Thermal Mode
feature on the pump is not intended to protect the
system plumbing from freezing.
•
In mild climate areas, when temporary freezing
conditions may occur, run your filtering equipment
all night to prevent freezing.
•
You are responsible for determining when freezing
conditions may occur. If freezing conditions are
expected, take the following steps to reduce the risk
of freeze damage. Freeze damage is not covered
under warranty.
To prevent freeze damage, follow the procedures below:
1. Shut off electrical power for the pump at the circuit
breaker.
2. Drain the water out of the pump housing by removing
the two thumb-twist drain plugs from the housing.
Store the plugs in the pump basket.
3. Cover the motor to protect it from severe rain, snow
and ice.
Note: The motor may be covered during a storm, winter
storage, etc., but never when operating or expecting
operation. Never wrap motor with plastic or other air
tight materials during winter storage.
