SECTION 6.
Maintenance
6A. General Maintenance
1.
Wash outside of filter with a mild detergent and
water. Rinse off with a hose. Do not use solvents
to clean the filter, solvents will damage the
plastic components of the filter.
2.
Inspect the sand bed at least once a year.
Remove any foreign material which has not been
backwashed out of the system.
3.
Check pressure during operation at least once a
week.
4.
Remove any debris from the skimmer basket.
5.
Check pump and filter for any leaks. If any leaks
develop, turn
off
the pump and call a qualified
pool service technician.
6B. Pressure Gauge
1.
During operation of the filtration system, check
the pressure gauge for air or water leaks at least
twice a week.
2.
Keep the pressure gauge in good working order.
If you suspect a problem with the gauge,
Teledyne Laars/Jandy Products recommends you
call a qualified service technician to do any
work on the filter/pump system.
SECTION 7.
Winterizing
7A. Winterizing
1.
Turn
off
the pump.
2.
Open pressure release valve and move the MPV
handle to a position between two ports. This will
allow air to flow to all ports.
3.
Remove any drain plugs from the filter.
4.
Drain system piping of all water.
5.
Cover the system with a tarpaulin or plastic
sheet to protect from the weather.
5B. Filter Disassembly/Assembly
1.
Backwash filter according to the instructions
under "Backwashing the Filter" (omit this step
when first filling a new filter).
2.
Stop the pump, disconnect the power if
necessary.
3.
Open pressure release valve on top of the filter
tank to release all air pressure from inside the
tank and system. On models with a top mounted
valve, the pressure release valve is on the
multiport valve.
4.
Remove the filter drain plug from the bottom of
the tank and drain any water remaining in the
system.
5.
Unscrew the multiport valve (on top mounted
models) and remove. On side mounted models
unscrew the cap on top of the filter tank.
6.
Before filling the filter tank with sand, make sure
that the correct grade and quantity is used (see
Section 2D).
7.
Before pouring the sand into the filter tank, do a
visual check of the laterals. Look for broken or
loose laterals. Replace if necessary.
8.
After removing the top cap, on Side Mount Filter
models, there will be one or two funnels visible.
Cover these funnels to prevent sand from
entering the laterals. Also, cover the breather
tube assembly. Be sure to uncover them after
step 10.
9.
To eliminate stress on the laterals, fill tank
with enough water to cover the laterals. Pour
sand in slowly.
10.
Wash all sand and debris away from the threads
of the filter tank. Remove covers over the
funnels.
11.
When assembling the top cap or MPV, check the
o-ring for cracks or tears. Replace if necessary.
12.
Thread the top cap or MPV into the filter tank.
Hand tighten only.
Caution
The pressure gauge is the primary indicator of how
the filter is operating. Maintain your pressure gauge in
good working order.
