OPERATION
NEVER run Max-E-Pro
®
High Efficiency Pool and
Spa Pump dry. Running pump dry may damage
seals, causing leakage and flooding. Fill pump with
water before starting motor.
Before removing trap cover:
1. STOP PUMP before proceeding.
2. CLOSE GATE VALVES in suction and discharge
pipes.
3. RELEASE ALL PRESSURE from pump and piping
system.
4. NEVER tighten or loosen clamp while pump is
operating!
If pump is being pressure tested, be sure pressure
has been released before
removing trap cover.
Do not block pump
suction. To do so with
body may cause severe or
fatal injury. Small children
using pool must ALWAYS
have close adult supervision.
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 20 minutes before
trying to work on it. An
automatic internal cutoff switch protects the motor from
heat damage during operation.
NOTICE: Maximum ambient temperature for motor
operation must not exceed maximum ambient
temperature rating on motor model plate.
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, remove trap
cover handle ring and trap cover; fill trap and pump with
water.
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.
Clean and inspect O-Ring; reinstall on trap.
Replace trap cover and handle ring on trap; turn handle
ring clockwise to tighten cover.
NOTICE: Tighten trap cover handle ring by hand only
(no wrenches)!
Pump should prime now. Priming time will depend on
vertical length of suction lift and horizontal length of
suction piping.
If pump does not prime, make sure that all valves are
open, suction pipe end is under water, and that there
are no leaks in suction pipe.
See Troubleshooting Guide, Page 10.
Routine Maintenance
The only routine maintenance needed is
inspection/cleaning of trap basket. Debris or trash that
collects in basket will choke off water flow through the
pump. Follow instructions below to clean trap:
1. Stop pump, close valves in suction and discharge,
and release all pressure from system before
proceeding.
2. Remove trap cover handle ring (turn
counterclockwise). If necessary, tap handles gently
with a rubber mallet.
3. Remove strainer basket and clean. Be sure all holes
in basket are clear, flush basket with water and
replace in trap with large opening at pipe connection
port (between ribs provided). If basket is replaced
backwards cover will not fit on trap body.
4. Clean and inspect lid O-Ring; reinstall on trap. tighten
pump.
DO NOT open the strainer pot if pump fails to
prime or if pump has been operating without 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, make 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 filter
and for proper operation of the system, clean
pump strainer and skimmer baskets regularly.
THIS FILTER 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 SEVERE INJURY, DEATH, OR
PROPERTY DAMAGE. TO AVOID THIS POTENTIAL
HAZARD, FOLLOW THESE INSTRUCTIONS.
Hazardous suction.
Can trap hair or
body parts, causing
severe injury or
death.
Do not block suction.
