  Replacement Kit Instructions    Jandy® JS Sand Filter Inlet and Outlet Fitting Parts Replacement Kit WARNING FOR YOUR SAFETY: This product must be installed and serviced by a professional service techni- cian, qualified in pool/spa pump and filter installation and maintenance. Improper installation and/ or operation can create dangerous high pressure which can cause product failure or also cause the filter lid to be blown off, possibly causing death, serious injury or property damage. Improper installation and/or operation will void the warranty. These instructions are to be used with the following Jandy Replacement Kit: R0487900 -- JS100-SM Nuts, Springs, and Inner Spacers Replacement Kit R0488600 -- JS100-SM Complete Outlet Fitting Replacement Kit R0488700 -- JS100-SM Complete Inlet Fitting Replacement Kit WARNING Before installing this product, read and follow all warning notices and instructions that accompany this filter replacement kit. Failure to follow warning notices and instructions may result in property damage, personal injury, or loss of life. This document gives instructions for replacing all of the Inlet and Outlet Fittings and related parts in WARNING all Jandy JS100-SM Model Side Mount Sand Filters.

Stand clear of the filter and start the pump. When a steady stream of water starts to come out of the air release valve, close the valve. There will be a steady stream of water flowing out of the backwash valve piping. Continue to backwash until the backwash water is clear (three (3) to five (5) minutes). 10. Turn the pump off. 11. If the multiport backwash valve has a Rinse position do the following: a. Set the selector handle in Rinse position. b. Start the pump and run for 30 to 40 seconds. This helps settle the sand bed and removes fine particles in the bottom of the sand bed. c. Stop the pump. 12.
