Step 7)
Attach DRAIN LINE to DRAIN LINE FITTING. To prevent back pressure from reducing fl ow
rate below minimum required for backwash, DRAIN LINE MUST be sized according to run
length and relative height. Be careful not to bend fl exible drain tubing sharply enough to
cause “kinking” (if kinking occurs DRAIN LINE MUST BE REPLACED). Typical examples of
proper DRAIN LINE diameters are:
1) 1/2” ID up to 15 ft. when discharge is lower than INLET.
2) 5/8” ID up to 15 ft. when discharge is slightly higher than the INLET.
3) 3/4” ID when drain is 25 ft. away and/or drain is installed overhead.
Some areas prohibit the use of fl exible drain lines. Check with local code offi cials prior to
installation.
Step 8)
Position DRAIN LINE over drain and secure fi rmly. To prevent backsiphoning of sewer
water, provide an air-gap of at least 2” or 2 pipe diameters between end of drain hose and
drain (Figure 3). DO NOT raise DRAIN LINE more than 10 ft. above fl oor.
Step 9)
Connect one end of the included 3/8” black Polyethylene tub-
ing to the brine fi tting located on the left side of the CONTROL
VALVE. Connect the other end to the SAFETY BRINE VALVE EL-
BOW inside of the brine well in the brine tank. To do so remove
the retaining clip from the brine line fi tting on the control valve.
The retaining clip is holding a plastic insert sleeve and needs
to be inserted into the polyethylene tubing before installing the
tubing into the fi tting elbow and hand tighten only.
CAUTION:
Do not use pliers or wrenches to tighten as damage may oc-
cur and will void the manufacturer’s warranty.
Step 10)
Install OVERFLOW LINE to brine tank OVERFLOW FITTING (Figure
2). Discharge of line must be lower than OVERFLOW FITTING. DO
NOT INTERCONNECT OVERFLOW LINE WITH VALVE DRAIN LINE.
Step 11)
Make certain BYPASS VALVE INLET and OUTLET KNOBS ARE IN
“BYPASS” position. After all plumbing connections have been
completed, open main water shut-off valve and restore power
to well pump. Check for leaks and correct as necessary.
Step 12)
Plug CONTROL VALVE POWER CORD into 110v/60Hz, non-switched
power source. Program the control valve (refer to page 3-1).
NOTE: Regeneration settings for the control valve are factory
preset. The control valve design permits adjustment of the salt
setting. This adjustment may be necessary when unusual op-
erating conditions exist, such as high concentrations of iron,
manganese or hardness and/or high fl ow rates or daily water
consumption.
Step 13)
Manually stage control to BACKWASH POSITION. Press and hold
REGEN button for 3 seconds. The valve will advance to BACKWASH POSITION. Unplug power cord to prevent the unit from advancing automatically.
Step 14)
Partially open INLET knob on bypass valve (Figure 4). This will allow the unit to fi ll slowly from the bottom up, reducing air entrapment. Allow unit
to fi ll slowly, failure to do so could result in loss of resin to the drain. Once a steady stream of water, no air, is fl owing to drain the inlet and outlet
knobs on the bypass can be fully opened (refer to Figure 4).
Step 15)
Plug the power cord back into the power source. Press the REGEN button and wait for the valve to advance to the next regeneration position.
Repeat the process until the valve is in Service Position (Time will be on the display).
Step 16)
Refer to
Section 3: Control Valve Programming and Regeneration Instructions
, on how to set control valve for proper set up and regeneration
settings.
SPECIAL SERVICE INSTRUCTIONS:
Under normal circumstances removal of valve should not be required. However, if it must be removed, it can be done by rotating the valve head assem-
bly to the left or counter-clockwise. Pressure should be relieved before attempting any disassembly. 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.
