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.
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.
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.
1. The Posi-Clear™ RP Cartridge Filter operates under
pressure. When the lock ring is installed 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. Be sure the maximum pressure of the filter system
does not exceed the maximum 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.
5.
Clean your filter when pressure reads between
8-10 psi higher than the "Original Starting
Pressure", or when significant reduction in flow
is noticed. The pressure reading increases as it
filters dirt from your pool. This build up of pressure
will vary due to different bathing loads, temperature,
environmental conditions, etc.
Note: When using a variable speed pump the
"Original Starting Pressure" will be dependent on
the pump speed (RPM) when recording the original
operating pressure. Record the "Original Pump
RPM" in Table 1.
Note: When the cartridge element filter is used on
new pools and after cleaning the elements, introduce
into the system 0.5 pounds of diatomaceous earth per
every 100 square feet of filter area, (a one-pound coffee
can equals 0.5 pounds of diatomaceous earth). Mix
the diatomite with water and pour it into the skimmer
after the pump is primed and the system is operating.
This will enhance the filtration of your water.
GENERAL INFORMATION
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 you do not know the pool or spa system operating
pressure, install an ASME approved automatic
Pressure Relief or Pressure Regulator in the
circulation system set to the lowest working pressure
of any of the components in the system.
