Self-Priming Pool/Spa Pump Installation and User’s Guide
OPERATION
Pressure Test
Before performing pressure tests on the system, make the
following safety checks:
1. Be sure all clamps, bolts, lids and system accessories
are properly and tightly installed.
2. Release all air in the system.
3. Water pressure during test must not exceed 25 PSI (7.5
kg/cm
2
).
4. Water temperature during test must not exceed 100˚F
(38˚C).
5. Limit pressure test to 24 hours. After test, visually
inspect the system to ensure it is ready for operation.
Priming the Pump
1. Relieve all air from filter and piping system. See the
filter owner’s manual for correct procedure.
2. In a flooded suction system (water source higher than
the pump), the pump will prime itself when suction and
discharge valves are opened.
3. If pump is not in a flooded suction system, unscrew and
remove strainer cover; fill strainer and pump with water.
4. Clean and inspect O-Ring; reinstall on strainer groove.
Note:
Do not lubricate the strainer lid O-Ring. The
original equipment O-Ring contains a permanent
internal lubricant.
Note:
If you replace the O-Ring with a non-internally
lubricated O-Ring, you may need to apply a silicone
based lubricant.
5. Replace strainer lid, turning clockwise to tighten the
cover. Hand tighten only.
6. Pump should now prime. Priming time will depend on
vertical length of suction lift and horizontal length of
suction piping.
Note:
If pump does not prime, make sure that all valves
are open, suction pipe end is under water, pump is not
trying to lift water more than 10’(3m), and that there are
no leaks in suction pipe. See Troubleshooting, Page 8.
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.
Draining the Pump
1. Pump down the pool, spa or hot tub water level below
all inlets.
2. Remove strainer lid (turn counterclockwise). If
necessary, tap handles gently with a rubber mallet. Low
pressure air can be used to remove remaining water
from the piping.
3. Cap inlet piping after draining to keep water out
of the pipes.
4. To prevent pump from freezing, remove strainer lid and
drain the pump through the two drain plugs provided.
• Gravity drain system as far as possible.
• Protect areas which retain water with non-toxic
propylene glycol antifreeze (“RV” antifreeze).
5. Clean pump thoroughly; replace strainer lid.
6. Be sure motor is kept dry and covered.
Winterizing
1. Drain all water from pump and piping when expecting
freezing temperatures or when storing pump for a long
time (see instructions below).
2. Keep motor dry and covered during storage.
3. To avoid condensation/corrosion problems, do not cover
pump with plastic.
For outdoor/unprotected installations:
1. Enclose entire system in a weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow
ventilation; do not wrap system in plastic.
3. Use a 40% propylene glycol/60% water solution to
protect pump to -50°F (-46°C).
HAZARDOUS VOLTAGE!
To avoid dangerous or
fatal electrical shock hazard, turn OFF power to
the motor at the circuit breaker before draining the pump.
SEPARATION HAZARD!
Purging the system with
compressed air can cause components to separate,
with risk of severe injury or death to anyone nearby. Use only a low pressure
(below 5 PSI), high volume blower when air purging the pump, filter, or piping.
Allowing the pump to freeze will damage pump and
void warranty
Do not use anti-freeze solutions (except propylene
glycol) in your pool/spa system. Propylene
glycol, “RV antifreeze”, is non-toxic and will not damage plastic system
components; other anti-freezes are highly toxic and may damage plastic
components in the system.
