Pentair Clean & Clear Plus Installation Manual page 4

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 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.
3. Clean your filter when pressure reads between 0.8 - 1 bar 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.
¾ My original starting pressure is ___________
¾ I should clean the filter cartridges at __________.
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.
This filter 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 be blown off which can result in severe injury, death, or
property damage. To avoid this potential hazard, follow these instructions.
2. Be certain the O-ring is in position in the lower tank half. Place the filter lid over the lower tank half, making sure it is fully and firmly seated on the tank half, see
Figure 1.
3. Place lock ring over the tank lid, and centering the lock ring on the threads of the tank body. Turn the lock ring clockwise until the safety latches click and the lock
ring hits the stops on the body. Do not attempt to over-tighten the lock ring after lock ring has hit the stops on the body.
4. Follow the System Restart Instructions in Section C.
C. SYSTEM RESTART INSTRUCTIONS
1. Open the High Flow TM manual air relief valve until it snaps into the full open position
(this only requires a quarter turn counter-clockwise).
Opening this valve rapidly, releases air trapped in the filter.
2. Stand clear of the filter tank, then start the pump.
3. Close the High Flow™ manual air relief valve after a steady stream of water appears.
4. The system is not working properly if either of the following conditions occur.
a. A solid stream of water does not appear within 30 seconds,
after the pump's inlet basket fills with water.
b. The pressure gauge indicates pressure before water outflow appears.
If either condition exists, shut off the pump immediately, open valves in the water return line to relieve pressure, and clean the air relief valve.
