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 20 minutes before trying to work on
it. An automatic internal cutoff switch protects the motor
from heat damage during operation.
Priming Pump
Release all pressure from filter, pump, and piping
system; see the 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.
If pump is not in a flooded suction system, unscrew and
remove trap cover (see Figure 8); fill trap and pump with
water.
Clean and inspect O-Ring; reinstall on trap cover.
Do not lubricate the trap cover O-Ring. The original
equipment O-Ring contains a permanent internal
lubricant.
NOTICE: If you replace the O-Ring with a non-internally
lubricated O-Ring, you may need to apply a silicone
based lubricant.
Replace trap cover on trap; turn clockwise to tighten
cover.
