A. GENERAL INFORMATION
1. This 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. Pressures above 50 psi can cause the lid
to be blown off, which can result in severe injury, death or property damage.
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 for the lowest working pressure of any of the components in the
system.
3. The pressure gauge is the primary indicator of how the filter is operating. Maintain your pressure gauge in
good working order.
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.
4. Clean your filter when pressure reads between 8-10 psi higher than the original starting pressure. Your
filter pressure reading will increase as it removes dirt from your pool. However, this buildup of pressure
will vary due to different bathing loads, temperature, weather conditions, etc.
a. MY ORIGINAL STARTING PRESSURE IS ___________ psi (pounds per square inch).
I SHOULD CLEAN THE FILTER CARTRIDGES AT __________ psi.
When the cartridge element filter is used on new pools and after cleaning the elements, introduce into the system .5 pounds
of diatomaceous earth per every 100 square feet of filter area, (a one-pound coffee can equals .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.
B. LOCK RING INSTALLATION INSTRUCTIONS
These instructions MUST BE FOLLOWED EXACTLY to prevent the lid from blowing off during system restart or
later operation.
1. Perform the following steps before working on any part of the circulating system (e.g., lock ring, pump,
filter, valves, etc.).
a. Turn the pump off and shut off any automatic controls to ensure that the system is not
inadvertently started during servicing.
b. Open the High Flow™ manual air relief valve.
c. Wait until all pressure is relieved. Never attempt to assemble, disassemble or adjust the
filter lock ring while there is any pressure in the filter.
