Step 7) Attach DRAIN LINE to DRAIN LINE FITTING. To prevent back pressure from reducing flow rate below minimum required for backwash, DRAIN LINE MUST be sized according to run length and relative height. Be careful not to bend flexible 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 flexible drain lines. Check with local code officials prior to installation.

Step 8) Position DRAIN LINE over drain and secure firmly. 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 floor.

Figure 3

Step 9) Connect one end of the 3/8” black Polyethylene tubing to the brine fitting located on the left side of the CONTROL VALVE. Connect the other end to the SAFETY BRINE VALVE ELBOW inside of the brine well in the brine tank. To do so remove the retaining clip from the brine line fitting on the control valve. The retaining clip is holding a plastic insert sleeve and needs to be inserted into the polyeth- ylene tubing before installing the tubing into the fitting elbow and hand tighten only. CAUTION: Do not use pliers or wrenches to tighten as damage may occur and will void the manufacturer’s warranty.

Step 13)	Partially open INLET knob on bypass valve (Figure 4). This will
	allow the unit to fill slowly from the bottom up, reducing air en-
	trapment. Allow unit to fill slowly, failure to do so could result in
	loss of resin to the drain. Once a steady stream of water, no air,	Figure 4. BYPASS VALVE
	is flowing to drain the inlet and outlet knobs on the bypass can be
	fully opened.

Step 14)	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 15)	Refer to Section 3: Regeneration Instructions, on how to set control valve for proper set up and regeneration
	settings.
	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 operating conditions exist, such as high
	concentrations of iron, manganese or hardness and/or high flow rates or daily water consumption.
SPECIAL SERVICE INSTRUCTIONS:
	Under normal circumstances removal of valve should not be required. However, if it must be removed,	it
	can be done by disassembling the quick release clamp, and latch. Pressure should be relieved before attempting any
	disassembly. Upon reassembly, all o-rings should be lubricated with silicone grease. Reassemble clamp as shown in
	Figure 5. MAKE SURE ARROWS ON LATCH SIDE OF CLAMP ARE ALIGNED.
