Operation; Priming The Pump - Pentair Sta-Rite EcoSelect Enviromax 800 Owner's Manual

NEVER run pump dry. Running pump dry may damage seals, causing leakage
and flooding. Fill pump with water before starting motor.
Freezing conditions will damage the unit, as water expands as it freezes. Ensure
that the EnviroMAX 800 is located so that it is not prone to freezing, or ensure
that the product is disconnected and dried of water during cold conditions.
Trapped air in system can cause explosion. Ensure all air is out of the system
before operating or testing equipment
Fire and burn hazard. Modern motors run at high temperatures. To reduce the
risk of fire, do not allow leaves, debris, or foreign matter to collect around the
pump motor. To avoid burns when handling the motor, let it cool for at least 20
minutes before trying to work on it.
Small children using pool must ALWAYS have close adult supervision
Pump suction is hazardous and can trap and drown or disembowel bathers. Do
not use or operate pump, pool/spas if a suction outlet cover is missing, broken,
or loose. Follow the guidelines below for a pump installation which minimises
risk to users of pool and spas.
NEVER tighten or loosen trap lid while pump is operating.

1. Priming the pump

It is not necessary to lubricate
the oring. The original equipment
O-ring contains a permanent
internal lubricant
a. Before removing trap lid, SWITCH OFF POWER SUPPLY to pump.
b. CLOSE SHUT-OFF VALVES on suction and discharge pipes, if present.
c. Remove the trap lid (turn anti-clockwise)
d. Fill trap tank with water.
e. Check the lid o-ring and sealing surface, ensure there is no dust or debris on either, and replace the
lid (turn clockwise to tighten by hand only - no wrenches!).
f. Open the shut-off valves on the suction and discharge pipes, if present.
g. Release all air from filter, pump and piping system (refer filter owner's manual). In a flooded suction
system (water source higher than pump), pump will prime itself when suction and discharge valves
are opened and air is released.
h. Switch on power to the pump to start.
i. Pump should start to prime now. Priming time will depend on vertical height of suction lift and
horizontal length of suction piping but is generally between 30 seconds to 3 minutes under normal
installation conditions.
j. The EnviroMAX 800 will start slowly but ramp up to high speed for the first 2 minutes to assist priming.
It will then switch to the selected speed.
* Should the pump not prime, ensure that all valves are open, lint trap is clear of debris and suctions and suction pipe end is submersed in water, and that there
are no leaks in suction pipe. See troubleshooting guide.
