WINTERIZING FILTER
In areas where subfreezing temperatures can be expected, the filter should be drained to protect the filter from damage.
1. The filter should be disassembled and the filter cartridges elements cleaned or replaced.
2. Follow directions under FILTER DISASSEMBLY INSTRUCTIONS
3. Then follow REMOVING CARTRIDGES per instructions
4. Reassemble per FILTER RE-ASSEMBLY INSTRUCTIONS.
5. Be sure to leave the drain plug unattached during the winter season to avoid cracking the filter body.
Consult your local authorized Hayward dealer or service center. No returns may be made directly to the factory without the
expressed written authorization of Hayward Pool Europe.
Remedy
Low water flow
1. Check skimmer and pump strainer
baskets for debris.
2. Check for restrictions in intake and
discharge lines
3. Check for air leak in intake line
(indicated by bubbles returning to pool).
