System Inspection
The pool circulation system should be
frequently inspected for debris and
signs of leaks.
Any time the system
is opened, air must
be bled from the filter using the air
relief valve. Air trapped in the system
can cause an explosion.
1.
Ensure pump is OFF.
Turn off any
automatic controls and lock out / tag
out switches and / or circuit breakers
to ensure the system cannot
inadvertently turn on.
Verify power is
removed from the
system. Disconnect, tag and lock out
power source before attempting to
install, service, relocate or perform any
maintenance.
2. Close system isolation valves, if
installed.
3. Remove debris from the pool
skimmer basket.
4. Open the air relief valve to release
any pressure in the system.
5. Check system for signs of leaks. If
found, consult the owner’s manual
of the leaking equipment.
6. Remove pump trap cover and
basket; remove debris. Refer to the
pump owner’s manual for more
specific information.
7. Replace the pump basket and
trap cover according to the pump
owner’s manual.
8. Open system isolation valves, if
installed.
9. With the air relief valve open, stand
clear of the filter and start the
pump.
10. Once a steady stream of water flows
from the air relief valve, close the
valve.
Do not over tighten
valve. If the valve
fails to seal, turn the pump off, remove
the top assembly and inspect the valve
o-ring. Reseat or replace if necessary.
11. When the system has returned to
normal operation, check the filter
operating pressure. If the filter
pressure is 8 psi to 10 psi (55 kPa -
69 kPa) above the start-up pressure,
the filter needs to be cleaned. Refer
to the “Cartridge Cleaning” section
of this owner's manual (Page 8).
Winterizing
Protect the filter from freezing. If
possible, take the system indoors for
storage.
1.
Ensure pump is OFF.
Turn off any
automatic controls and lock out / tag
out switches and / or circuit breakers
to ensure the system cannot
inadvertently turn on.
Verify power is
removed from the
system. Disconnect, tag and lock out
power source before attempting to
install, service, relocate or perform any
maintenance.
2. Clean the filter. Refer to the
“Cartridge Cleaning” section of this
owner's manual.
3. Remove the filter cartridge and store
in a warm, dry area. Protect the
cartridge from sunlight.
4. Cover the filter with plastic or a tarp
to prevent water from entering the
assembly and freezing.
Failure to follow
the above steps
could cause the filter assembly to
expand and crack. This will void the
warranty.
Troubleshooting Guide
Short Cycle Time
Cycle time will vary between
installations and different areas of the
country. The following remedies are for
cycle times shorter than normal:
t
New pool / spa installation: Until the
water in a new pool is completely
filtered, cycle time will be short due
to plaster dust and construction
debris. Thoroughly clean the
cartridge. Refer to the "Cartridge
Cleaning" section of this owner's
manual.
t
Low chlorine residual: Maintain
proper chlorine residual (consult
local pool professional for
recommendation.)
t
Dirty or plugged filter cartridge:
Thoroughly clean the filter. Follow
the instructions in the "Cartridge
Cleaning" section of this owner's
manual.
t
Excessive air in filter: Vent all air
from the filter tank and check
system for suction pipe leaks or low
water level. Also, check and clean air
bleed tube (See Figure 5).
