Sand Filter.
WARNING — THIS FILTER OPERATES UNDER HIGH PRESSURE
When any part of the circulating system, (e.g., closure, pump, filter, valve(s), etc.), is serviced, air can enter the system and become
pressurized. Pressurized air can cause the top closure 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 heater.
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 closure FOLLOW THE FILTER CLOSURE WARNINGS EXACTLY.
4. Once service on the circulating system is complete FOLLOW INITIAL START-UP INSTRUCTIONS 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 filter is properly mounted and positioned according to instructions provided.
Note: Turn off power to unit prior to attempting service or repair.

before backwashing.
3. Improper amount or wrong sand size. Check sand bed depth and sand size or consult a pool
service technician.
4. Inadequate turnover rate. Run system for longer time or consult dealer or pool
service technician.
High filter pressure 1. Insufficient backwashing. Backwash until effluent runs clear.
2. Sand bed plugged with mineral deposits. Chemically clean filter.
3. Partially closed valve or restriction in return. Open valve or remove obstruction in return line.

3. Plugged sand bed. Manually remove top 1” surface of sand bed, replace with new
sand and chemically clean entire sand bed as described in the
Chemical Cleaning Procedure.
