SECTION 5: MAINTENANCE
Plumbing System Clean-Up
For your new system to operate properly, you may need to clean the entire plumbing system of the precipitated iron that has collected in it or iron “bleed”
(staining) will continue to be a problem. The plumbing system includes all water treatment equipment (such as iron reduction systems), water heaters, toilets,
and dishwashers. Please refer to the appropriate equipment owner’s manual for instructions.
General Maintenance
Periodic media replenishment will be required if your raw water has a pH below 7 and/or a manganese content over 0.2 ppm. The frequency of replenishment
will depend on raw water pH; hardness; iron; manganese; amount of water used; and the size of the fi lter selected.
Should your raw water have a low pH, it is recommended that you check the media level every 6-12 months. To check the level follow these steps:
1) Place light behind media tank and observe media level. If media is down 2-3 inches below line on side of tank, disconnect control valve from bypass
valve. Remove control valve from media tank by grasping the control valve and turn counter clockwise. Cover the distributor tube with centering tool to
prevent media from entering the distributor tube. Add ph-Plus
® and reattach valve. Manually backwash fi lter to mix ph-Plus into media bed.
If you are unable to see through tank with light proceed to #2.
2) Turn bypass valve to “bypass” position.
3) Manually stage fi lter into “backwash” to relieve water pressure.
4) Disconnect control valve from bypass valve. Remove control valve from media tank by grasping the control valve and turn counter clockwise.
5) Using a yard stick, measure media level. Remember media should be down 16-17 inches from the top of the media tank.
6) If media is down 2-3 inches, siphon water from tank and add ph-Plus to return the level to the proper depth.
When the media level is below 20 inches from the tank top, replenish it with the original media blend.
IMPORTANT NOTE IMPORTANT NOTE
When adding media, cover the distributor tube with centering tool to prevent media from entering the distributor tube.
Over time it is best to schedule maintenance frequently enough so only a couple of bottles of ph-Plus is required to replenish the fi lter. ph-Plus is sold in 3.5
pound bottles by your dealer.
Always backwash fi lter immediately following media replenishment.
Another maintenance step which may be required is resetting the timer to the proper time of day. It may be in error due to power outages and/or changes due
to daylight savings time. This should be checked at least every six months.
Special Service Instructions:
Under normal circumstances removal of the valve should not be required. However, if it must be removed, disconnect the plumbing attached to the bypass valve
fi rst. Then, rotate the valve head assembly to the left or counter-clockwise. Before attempting any disassembly, pressure should be relieved by shutting off water to
the system and opening a faucet. Upon reassembly, all o-rings should be lubricated with silicone grease. Reattach valve head assembly by rotating to the right or
clockwise until valve head assembly is seated to the tank hand tight. Reconnect the plumbing to the bypass valve.
