IMPORTANT WARNING AND SAFETY INSTRUCTIONS
HAZARDOUS PRESSURE: STAND CLEAR OF
PUMP AND FILTER DURING START UP
Circulation systems operate under high pressure.
When any part of the circulating system (i.e.
clamp ring, pump, filter, valves, etc.) is serviced,
air can enter the system and become pressurized.
Pressurized air can cause the pump housing cover filter lid and valves
to violently separate which can result in severe personal injury or death.
Filter tank lid and strainer cover must be properly secured to prevent
violent separation. Stand clear of all circulation system equipment when
turning on or starting up pump.
Before servicing equipment, make note of the filter pressure. Be sure
that all controls are set to ensure the system cannot inadvertently start
during service. Turn off all power to the pump.
IMPORTANT: Place filter
manual air relief valve in the open position and wait for all pressure
in the system to be relieved.
Before starting the system, fully open the manual air relief valve and place
all system valves in the “open” position to allow water to flow freely from the
tank and back to the tank. Stand clear of all equipment and start the pump.
IMPORTANT: Do not close filter manual air relief valve until all air
has been discharged from the valve and a steady stream of water
appears.
Observe filter pressure gauge and be sure it is not higher than
the pre-service condition.
The following information should be read carefully
since it outlines the proper manner of care and
operation for your filter system. As a result of following these instructions
and taking the necessary preventative care, you can expect maximum
efficiency and life from your filtration system.
For Installation of Electrical Controls at Equipment Pad (ON/OFF
Switches, Timers and Automation Load Center)
Install all electrical controls at equipment pad, such
as on/off switches, timers, and control systems,
etc. to allow the operation (startup, shut-down, or
servicing) of any pump or filter so the user does not
place any portion of his/her body over or near the
pump strainer lid, filter lid or valve closures.
This installation should allow the user enough space to stand clear of
the filter and pump during system start-up, shut down or servicing of the
system filter.
General Installation Information
The following information should be read carefully since it outlines the
proper manner of care and operation for your filter system.
You can expect maximum efficiency and life from your filtration system by
following these instructions and taking the necessary preventative care.
• Have a trained pool professional perform all pressure tests.
• Do not connect the system to a high pressure or city water system.
• Trapped air in the system can create a hazardous condition. BE
SURE to purge all air from the system before operating or testing
equipment.
• DO NOT pressure test with compressed air!
• Piping must conform to local/state plumbing and sanitary codes.
• Support piping independently to prevent strains on filter or valve.
• Fittings restrict flow; for best efficiency, use the fewest possible
fittings.
• A check valve installed ahead of the filter inlet will prevent contaminants
from draining back into the pool.
• A check valve installed between the filter and heater will prevent
hot water from backing up into the filter and deforming the internal
components.
• All wiring, grounding and bonding of associated equipment must
meet local and/or National Electrical Code standards.
Only a qualified plumbing professional should install this filter. Refer to
the “Important Warning and Safety Instructions on pages i-ii for additional
installation and safety information.
SERIOUS BODILY INJURY OR DEATH CAN
RESULT IF THIS FILTER IS NOT INSTALLED
AND USED CORRECTLY.
INSTALLERS, POOL OPERATORS AND POOL
