Q-SERIES Cartridge Style D.E. Filter Installation and User’s Guide
GENERAL INFORMATION
Filter Overview
• Four easily removable, large-capacity cartridges provide
maximum filter surface area for greater dirt-trapping
capacity and longer periods between cleanings.
• Full 2-1/2” x 3” bulkhead unions for improved hydraulic
efficiency and easy piping installation.
• HiFlow™ Manual Air Relief Valve for rapid air release.
• Conveniently located 2” drain for easy and complete
draining.
• Durable 8 oz. polypropylene cartridge media has
superslick surfaces, making them easier to clean than
conventional cartridge filters.
General Operation Information
Read and follow all instructions and warnings before
installing or servicing your filter. Proper installation and
operation can prevent unnecessary repairs and maintenance.
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. The maximum working pressure of this filter is 50 psi.
Never subject this filter to pressure in excess of this
amount - even when conducting hydrostatic pressure
tests.
3. Ensure the maximum working pressure of the filter
system does not exceed the maximum working
pressure of any components within the system during
hydrostatic or external leak tests. Consult the maximum
pressure stated on each component of the system.
4. The pressure gauge is the primary indicator of how
the filter is operating. Maintain your pressure gauge in
good working order (refer to
Maintaining the Pressure
Gauge
).
5. Never operate filter in excess of three minutes without
use of diatomaceous earth. Diatomaceous earth is the
substance that filters the water, the filter cloth merely
supports the diatomaceous earth. Operating without
diatomaceous earth will damage filter cartridges and
shorten filtering cycles.
Maintaining the Pressure Gauge
The pressure gauge is the primary indicator of how
the system operates. It is critical to keep the pressure
gauge in good condition.
Replace pressure gauge (P/N 190058) if any of
the requirements below are not met:
1. Pressure gauge at zero (0) when pressure is
relieved and system is turned off.
2. Pressure gauge reads correctly while system is
in operation.
3. The pressure gauge is readable and not
damaged in any way.
Pressure Tests
When performing hydrostatic pressure tests or when
testing for external leaks of the completed filtration
and plumbing system, ensure that the Maximum
Pressure that the filtration system will be subjected
to
DOES NOT EXCEED THE MAXIMUM WORKING
PRESSURE OF ANY OF THE COMPONENTS
CONTAINED WITHIN THE SYSTEM.
In most cases, the maximum pressure will be
stated on each component of the system. If doubt
exists as to the pressure to which the system will
be subjected, install an ASME approved automatic
Pressure Relief or Pressure Regulator in the
circulation system set to the lowest working pressure
of all of the components in the system.
THIS SYSTEM OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system (e.g., Lock Ring, Pump, Filter, Valves, etc.) is serviced, air can enter the system and become
pressurized. Pressurized air can cause the lid to separate which can result in serious injury, death, or property damage. To avoid this
potential hazard, follow the instructions below.
Your filter is a piece of machinery, do not tamper with it,
attempt to disassemble it or otherwise adjust it unless you
fully understand it's operation. Serious injury or death can
occur if the equipment is improperly handled. Consult a pool
service professional for maintenance and service assistance.
