VST Variable Speed Pump Installation and User’s Guide
Restarting the Pump
If pump is installed below the water level of the pool,
close return and suction lines prior to opening the
strainer pot on pump. Make sure to re-open valves prior
to operating.
TO PRIME THE PUMP:
1. Press Start/Stop to stop the pump and disconnect
all power to the pump at the circuit breaker.
2. Relieve all pressure from the ltration system at the
lter air relief valve.
3. Remove the strainer pot lid by twisting it in a counter-
clockwise direction.
4. Fill the strainer pot up to the inlet port with water.
5. Place the lid onto the strainer pot, then turn
clockwise to lock in place.
Note: The lid is properly locked when the handles
are nearly perpendicular to the pump body.
6. Return power to the pump at the circuit breaker.
7. Open the lter air relief valve.
8. Stand clear of the lter and press the Start/Stop
button to start the pump.
9. Bleed air from the lter air relief valve until a steady
stream of water appears, then close the relief valve.
10. The pump will run a priming cycle and, if successful,
begin normal operation.
DO NOT run the pump dry. The shaft seal will
be damaged and require replacement.
ALWAYS maintain proper water level in your pool (half way up
the skimmer opening). If the water level falls below the skimmer
opening, the pump will draw air through the skimmer, lose prime
and cause the pump to run dry. Continued operation in this manner
could cause a loss of pressure, damage the pump and/or property
or personal injury.
Winterizing
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.
In mild climate areas, when temporary freezing
conditions may occur, run your ltering equipment all
night to prevent freezing.
TO PREVENT FREEZE DAMAGE:
1. Press Start/Stop to stop the pump and disconnect
all power to the pump at the circuit breaker.
2. Disconnect all power to the pump at the circuit
breaker.
3. Relieve all pressure from the ltration system at the
lter air relief valve.
4. Remove both drain plugs from the bottom of the
strainer pot and drain the pump. Store the plugs in
the strainer basket.
5. Cover the motor to protect it from severe rain, snow
and ice.
Note: Do not wrap motor with plastic or other air
tight materials during winter storage. Never cover
the motor when operating or expecting operation.
