IMPORTANT NOTE
If an air bubble appears in the discharge line of the feed pump, remove the discharge line at the injection point, hold the tube vertical to allow air bubble
to be discharged and replaced with sulfur reduction media. Unplug the feed pump, place fi nger over the end of the feed line, replace tubing to the injection
point quickly. taking care to minimize any fl uid loss during reconnection. Plug feed pump back into receptacle.
Step 10
Set feed pump stroke length to 50%. Make certain that fi lter bypass valve is in bypass position (Figure 3). Turn on power to well pump. Allow water system to repres-
surize. After system has pressurized check for leaks in plumbing.
Step 11
Open a cold water faucet, so that well pump continues to run at 1/2 pressure; i.e., 30 psi if system operates at 20/40 psi. Draw sample of water from test cock.
Adjust feed pump rate just enough to eliminate sulfur odor in water coming from test cock. (Dark brown color of sample water is normal and is caused by precipitated
sulfur and will be reduced by the sulfur reduction system). Refer to Section 4 on dilution procedures to fi ne tune sulfur reduction media feed rate and concentration
(dilution) for most effi cient and economical setting. Close cold water faucet.
IMPORTANT NOTE
Should a sulfur odor persist even when the dial setting is at its maximum, reread STEP 8. Also, check to determine if the odor is in the hot water only, and,
if it is, the hot water heater may need to be drained and cleaned.
Step 12
a) Make certain the 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.
b) Plug the control valve power cord into 110v/60Hz, non-switched power source. Program the control valve (refer to page 3-1).
NOTE: Backwashing 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 fl ow rates or daily
water consumption.
c) Manually set the control to backwash position. Press and hold the REGEN button for 3 seconds. The valve will advance to the backwash position. Unplug
power cord to prevent the unit from advancing automatically.
d) Partially open the inlet knob on bypass valve (Figure 3). This will allow the unit to fi ll slowly from the bottom up, reducing air entrapment. Allow the unit
to fi ll slowly, failure to do so could result in loss of resin to the drain. Once a steady stream of water, with no air sputtering, is fl owing to the drain, the
inlet and outlet bypass knobs can be fully opened (refer to Figure 3).
e) Plug the power cord back into the power source. Press the REGEN button and wait for the valve to advance to the next backwashing position. Repeat the
process until the valve is in the Service Position (Time of Day will be on the display).
f) Test for residual copper, the fi nal amount of copper that should be present in the fi lter water supply is < 0.5 ppm.
Step 13
Set the TIME-OF-DAY (see HOW TO SET TIME OF DAY). The backwashing frequency is factory preset for every other day. This frequency need not be adjusted un-
less the sulfur reduction is great enough to require daily backwashing. Refer to HOW TO CHANGE THE BACKWASHING PROGRAM SETTINGS if change is required.
NOTE: Should you experience a water system pressure loss or bleed-through of the precipitant prior to a scheduled backwash, put the system into a manual back-
wash and increase the frequency of backwashing.
IMPORTANT INSTRUCTIONS: If water is supplied by a public or community source, or water line is split-streamed anywhere ahead of the media tank (See Figure 1):
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.
