Max-Flo II ™ Series Page 14 of 16 Low Flow - Generally, Check For: (cont'd.) 2. Undersized pool piping. Solution: Correct piping size. 3. Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). Solution: Sand filters - backwash as per manufacturer's instructions; D.E. filters - backwash as per manufacturer's instructions; Cartridge filters - clean or replace cartridge. 4. Air leak in suction (bubbles issuing from return fittings). Solution: Re-tighten using Teflon tape. 5. Plugged, restricted, or damaged impeller. Solution: Replace including new seal assembly. Noisy Pump - Check For: 1. Air leak in suction piping, cavitations caused by restricted or undersized suction line or leak at any joint, low water level in pool, and unrestricted discharge return lines. Solution: Correct suction condition or throttle return lines, if practical. Holding hand over return fitting will sometimes prove this point or putting in a smaller eyeball fitting. 2. Vibration due to improper mounting, etc. Solution: Mount the pump on a level surface and secure the pump to the equipment pad. 3. Foreign matter in pump housing. Loose stones/debris hitting impeller could be cause. Solution: Clean the pump housing. 4. Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage which will allow chlorinated water to seep into bearings wiping out the grease causing bearing to whine. Solution: All seal leaks should be replaced at once. © Hayward Pool Products, 2005 All rights reserved. www.haywardpool.com USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
