Cartridge Cleaning Procedure; System Inspection/Winterizing - STA-RITE Posi Clear PXC95 Owner's Manual

CARTRIDGE CLEANING PROCEDURE

When to Clean the Filter: The filter cartridge should nor-
mally be removed and cleaned when the pressure gauge
reading increases 10 PSI over the start-up pressure.
Follow all steps in the "Disassembly" section of this
manual (Page 5).
NOTICE: When sanitizing your pool using PHMB (poly-
hexamethylene biquanide based) cleaners, use only
PHMB cleaners to clean the cartridge. When using
PHMB sanitizers, the filter cartridge MUST be cleaned
more thoroughly and frequently than for a pool using
chlorine. Follow manufacturer's instructions carefully.
Use of any other type of cleansers with PHMB pool sani-
tizers will void the filter's warranty.
1. Remove the drain cap and flush all foreign material from
the inside of the tank before removing the filter cartridge.
2. Allow the tank to drain.
3. Lift out the cartridge and hose it down thoroughly. Spray
the entire cartridge surface. Allow cartridge to drain.
4. Inspect the cartridge. If necessary, repeat the washing
operation. If the cartridge is damaged, replace it.
5. Follow all steps in the "Assembly" (Page 5) and "Initial
Startup" (Page 4) sections of this manual.
NOTICE: When this procedure no longer adequately
cleans the cartridge, discard the cartridge and replace it
with a new one.
SYSTEM INSPECTION
General:
NOTICE: DO NOT use solvents to clean the filter; sol-
vents may damage plastic components in the system.
NOTICE: Open the air release valve and bleed all air
from the filter each time the pump is stopped and
restarted.
Weekly Inspection:
1. Remove debris from the pool skimmer basket.
2. Stop the pump; open the air release valve to release all
pressure.
3. Remove the pump trap cover and basket; remove debris.
4. Check the pump for leaks. If found, see the pump
owner's manual.
5. Replace the trap basket and the cover. Tighten the
cover securely hand tight. DO NOT use a lid wrench
to tighten it.
6. Start the pump. When the filter air release valve runs
a solid stream of water, close the valve.
7. When the system has returned to normal operation,
check the filter pressure. If the filter pressure is 10 PSI
(69kPa) or more higher than the initial startup pres-
sure, the filter needs cleaning. See "Cartridge
Cleaning Procedure", at left.
WINTERIZING
NOTICE: Protect the filter from freezing. Allowing the fil-
ter to freeze will damage it and will void the warranty. If
possible, take the system indoors for storage.
1. Clean the filter according to instructions (left) before
winterizing.
2. Stop the pump.
3. Open the air release valve; open any system valves.
4. Remove the drain plugs from the trap, pump, and filter.
5. Gravity drain system and filter as far as possible.
6. Disassemble the filter (follow instructions under "Filter
Disassembly", Page 5). Remove the filter cartridge
and store it in a warm, dry area.
7. Cover the filter with plastic or tarpaulin to prevent
water entrance and freezing.
