Battery Replacement
Always replace the four “AA” alkaline batteries in the control
box when changing the prefilter and postfilter cartridges. Good
batteries are needed to assure proper indicator light operation.
Weak batteries may give a false indication. Changing the batteries
also resets the six month or 900 gallon period.
Postfilter Cartridge Replacement
Continuing from Prefilter Replacement Procedure (feedwater off, pressure
relieved):
Disconnect tubing at both ends. See figure 1, page 9.
Pull the filter from the holder and remove fittings from both
ends.
Remove the protective cap and depress the vacuum relief
valve stem, allowing air to enter the tank. Release the valve stem
AFTER
flow from the tank shutoff slows to a slight drip. Replace
the protective cap.
WARNING:
This valve stem is for vacuum relief only. Pressurizing
the tank may cause it to rupture. Do not attempt to pressurize the tank
.
Replace filter into the holder and reconnect the tubing at both
ends.
NOTE:
Be sure the flow arrow points downward.
