OPERATION
THIS FILTER OPERATES UNDER HIGH PRESSURE
When any part of the circulating system, (e.g.,lock ring, pump, filter, valve(s), etc.), is serviced, air can enter the system and
become pressurized. Pressurized air can cause the tank lid to separate which can result in severe injury, death, or property
damage. To avoid this potential hazard, follow these instructions:
1. If you are not familiar with your pool filtering system and/or heater:
a. Do NOT attempt to adjust or service without consulting your dealer, or a qualified pool technician.
b. Read the entire Installation & User's Guide before attempting to use, service or adjust the pool filtering system or
2. Before repositioning valve(s) and before beginning the assembly, disassembly, or any other service of the circulating
system: (A) Turn the pump OFF and shut OFF any automatic controls to ensure the system is NOT inadvertently started
during the servicing; (B) open the manual air bleeder valve; (C) wait until all pressure is relieved.
3. Whenever installing the filter lock ring, FOLLOW THE LOCK RING INSTALLATION INSTRUCTIONS (PAGE 3)
EXACTLY.
4. Once service on the circulating system is complete, FOLLOW INITIAL SYSTEM RESTART INSTRUCTIONS (PAGE 3)
EXACTLY.
5. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., closure, pressure gauge,
valve(s), o-rings, etc).
6. Be sure that the separation tank is properly mounted and positioned according to instructions provided.
General Information
1. The Sep 100
D.E. Separation Tank operates under pressure. When the lock ring is installed properly and operated
®
without air in the water system, the separation tank will operate in a safe manner.
The maximum working pressure of the separation tank is 50 psi. Never subject the tank to pressure in excess of this
amount - even when conducting hydrostatic pressure tests. Pressures above 50 psi can cause lid separation, which can
result in serious 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.
2. The pressure gauge is the primary indicator of how the separation tank is operating. Maintain your pressure gauge in
good working order.
Your separation tank 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.
3. 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.
4. Change valve positions;
• if using a multi-port valve, set to backwash position.
• if using a two position valve, reposition the valve to backwash position.
• if separation tank is plumbed to return water to pool, open by-pass valve.
• open manual air bleed on top of separation tank.
5. Stand clear of filter and separation tank. Start pump, this will circulate water backwards through the filter and flush
D.E. cake and contaminants into the separation tank. Close the manual air bleed on the top of the separation tank
when a steady stream of water emerges.
