7.
If the system is to be installed below water level,
valves should be on both the suction and return
lines to prevent back flow of pool water during
any routine servicing that may be required.
3C. Filter Installation
1.
This filter operates under pressure. When
clamped properly and operated without air in the
water system, this filter will operate in a safe
manner.
2.
If doubt exists as to the pressure which the
system will be subjected to, install an ASME
approved automatic Pressure Relief Valve or
Pressure Regulator in the circulation system for
the lowest working pressure of any of the
components in the system.
Caution
The pressure gauge is the primary indicator of how
the filter is operating. Maintain your pressure gauge in
good working order.
3.
Place on the concrete pad, lined up with the
inlet/outlet pipes (see Fig. 5).
4.
To reduce pressure losses, 2" (minimum) piping
is recommended.
5.
For best efficiency use the fewest possible
fittings. This will prevent a restriction in the
water flow.
6.
Make all plumbing connections in accordance
with local plumbing and building codes. Filter
connections are provided with an o-ring seal. Do
not use pipe joint compound, glue or solvent
on bulkhead connections.
7.
Keep piping tight and free of leaks. Pump
suction line leaks may cause air to be entrapped
in filter tank or loss of prime at the pump. Pump
discharge line leaks may show up as dampness
or jets of water.
8.
Support the inlet/outlet pipes independently to
prevent any undue strains on the filter valve.
9.
Connect the pipes using the unions supplied
with the filter. Do not use teflon tape or pipe
dope on any unions. Assemble the unions dry
and hand tighten.
10.
Be sure that all provisions for waste water
disposal meet local, state or national codes. One
hundred gallons or more of pool water will be
discharged during filter backwashing. Do not
discharge water where it will cause flooding or
damage.
WARNING
Water discharged from an improperly positioned filter
or valve can create an electrical hazard which can
cause death, serious injury or property damage.
SECTION 4.
Start-Up and Operation
WARNING
NEVER operate the filter system at more than 50
pounds per square inch pressure.
system in excess of 50 psi can cause the filter lid to
be blown off, which can cause death, serious
personal injury or property damage.
WARNING
NEVER start pump while standing within five (5) feet
of the filter.
Starting the pump while there is pressur-
ized air in the system can cause the filter lid to be
blown off, which can cause death, serious personal
injury or property damage.
Caution
Do not operate filter at water temperatures above
120° F (65.5° C).
4A. New Pool and Seasonal Start-Up
1.
With the pump off, set MPV to "Backwash"
position. Remove the hair/lint pot lid and fill
with water. Replace the hair/lint pot lid
2.
Open pressure release valve on filter or MPV.
3.
Stand clear of the filter, start the pump and
circulate the water backwards through the filter
to waste.
4.
Close pressure release valve when a steady
stream of water is moving through the filter.
5.
Run the pump for approximately five minutes or
until waste water is clear (this purges excess fine
particles from the system).
6.
Turn the pump off, and move valve handle to the
"Rinse" position. Stand clear of the filter, turn
pump on and circulate the water for 10 seconds.
7.
Turn pump off, move the valve handle to
"Filter". Stand clear of the filter, and start the
pump.
