Troubleshooting Guide - 3M AP902 Serie Instrucciones De Instalación Y Funcionamiento

To reduce the risk associated with property damage due to water leakage:
The disposable fi lter cartridge MUST be replaced every 12 months or at the rated capacity or if a noticable reduction
•
in fl ow rate occurs.
The contaminants or other substances reduced by this water filter are
not necessarily in all user's water.
Filter life depends on local water conditions and the volume of water
used. We recommend you change your filter as prescribed by the filter
documentation. However, it can be replaced earlier if there is a drop in
water pressure.
NOTE: Before changing cartridge, turn off water supply. Place a bucket
under filter to catch the small amount of water that will run out after
housing removal.
1. Close shut-off valves before and after filter head (upstream and
downstream valves 2 and 3).
2. Slide cartridge locking latch to the right and lift up.
3. With both hands, twist out filter cartridge by turning unit 90° to the
left and down.
4. Install new replacement cartridge into head by pushing
cartridge up and turning to the right until locking latch clicks into place.
5. Open faucet downstream of filter.
6. Open valves 2 and 3. Let water flush for 15 minutes, check for leaks.
Water Leaks at Fittings:
Repeat install procedure.
If Leaks Persist:
Check solder joints, unions and SQC connection. Shut off water at the main water supply shut-off valve, remove thread-
ed fittings, reapply PTFE tape in a clockwise (to the right) direction and screw back onto head assembly.
