6.4 Pump Reassembly

1. When installing the replacement seal into the seal plate,
use soapy water to wet the rubber boot before pressing it
into the seal plate.
2. Remount the seal plate(#9) to the motor mounting plate by
tightening the 4 bolts(#12).
3. Before installing the rotating part of the seal on the
impeller shaft, wet the impeller shaft with soapy water and
slide the seal to the impeller shaft end. Remove the dirt
from the contact surface of the seal with a clean cloth.
4. Screw impeller onto the motor shaft (clockwise to tighten).
Note: Place screwdriver in rear motor housing to prevent
fan/shaft from spinning.
5. Remount the diffuser(#7) onto the seal plate by tightening
2 Phillips head screws(#6).
6. Grease the diffuser quad ring and seal plate O-ring prior
to reassembly.
7. Assemble the motor sub-assembly to the strainer pot-
pump body(#4). Tighten the bolts until all 8 bolts are in
place.
8. Tighten the drain plugs(#20) and fill the pump with water.
9. Reinstall the pump lid and plastic clamp; see the next
section, 'Restart Instructions'.
Re-prime the system.

ENGLISH
DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start
leaking. If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water level. If the water
level falls below the suction port, the pump will draw air through the suction port, losing the prime and causing the
pump to run dry, resulting in a damaged seal. Continued operation in this manner could cause a loss of pressure,
resulting in damage to the pump case, impeller, and seal, and may cause property damage and personal injury.

6.5 Restart Instructions

If Variable Speed Pump is installed below the water level of
the pool, close return and suction lines prior to opening hair
and lint pot on pump. Make sure to re-open valves prior to
operating.
Priming the Pump
The pump strainer pot must be filled with water before
the pump is initially started.
Follow these steps to prime the pump:
1. Remove the pump lid plastic clamp. Remove the pump
lid.
2. Fill the pump strainer pot with water.
3. Reassemble the pump cover and plastic clamp onto the
strainer pot. The pump is now ready to prime.
4. Open the air release valve on the filter, and stand clear of
the filter.
5. Turn on the power to the pump.
6. Press the Start/Stop button on the drive keypad. If the
pump is currently scheduled to run it will start.
Note: If the pump is not schedule to start, press a Speed
button to begin a manual override that will start the pump.
7. When water comes out of the air release valve, close the
valve. The system should now be free of air and
recirculating water to and from the pool.
