Step 5
The drain line fl ow control elbow is designed to accept either 5/8” polyethylene tubing or 3/4” NPT pipe fi ttings. To utilize the NPT connection, set aside the supplied
nut and insert sleeve. Use customer supplied fi ttings to adapt drain line to elbow. Support of the drain line is required or the elbow could be damaged unexpectedly
and cause a water leak in the home or facility. Copper, PVC or CPVC pipe can be used to adapt to the 3/4” NPT threads on the elbow for long or high drain lines. Use
only thread sealing tape to seal the threads, hand tighten the fi tting.
To use polyethylene tubing as a drain line, remove the supplied nut and fi nd the insert that was shipped in the part kit box. Slide the nut over the polyethylene tubing
and insert the sleeve into the tubing. Slide the end of the tubing into the elbow and using your hand thread the nut onto the elbow and hand tighten only. Overtight-
ening could cause the nut to fail unexpectedly and cause a water leak in the home or facility.
Typical examples of proper drain line diameters are:
1/2” ID up to 15 feet when discharge is lower than the inlet.
5/8” ID up to 15 feet when discharging is slightly higher than the inlet.
3/4” ID when drain is 25 feet away and not higher than 4 feet above control valve.
Avoid installing drain line overhead or using fl exible vinyl turing; either may result in system not operating properly and reducing arsenic suffi ciently. Some areas
prohibit the use of fl exible drain lines. Check with local code offi cials prior to installation to ensure you conform to local plumbing codes.
Step 6
Position DRAIN LINE over drain and secure fi rmly. To prevent back-siphoning of sewer water, provide an air gap of at least two (2) inches or two (2) pipe diameters
between end of drain hose and drain (Figure 4). Do not raise DRAIN LINE more than ten (10) ft. above fl oor.
Step 7
Plug control valve into properly grounded 110V 60 Hz non-switched electrical outlet. Check with your local
code enforcement offi cer to determine if it meets local code.
Step 8
Set the time of day by referring to Section 2 Installation “How To Set Time Of Day” on page 2-5.
Step 9
Open the valve on the water supply as required to repressurize the water line to the home or facility. Do not
forget to turn the electricity to the water heater or water boiler on once water has been allowed to fl ow into
that device. Check for leaks on all connections, correct as necessary.
Step 10
Manually initiate backwashing of the arsenic reduction system by referring to the “How To Manually Initiate
Regeneration (Backwashing)” section of Control Valve settings on page 2-7.
Step 11
Once the valve is in the backwash position (C1 appears on the display) slowly open the inlet side of the bypass valve to allow water to fl ow into the fi lter. Water should
start to fl ow to drain. Allow for any air that might have been trapped (or vent from the titanium oxide) to leave the fi lter and go to the drain. This will be detected by
changes in noise in the drain line or is visible in the semi-transparent tubing. Once the air is gone, open a drain port, spigot or faucet slightly, slowly open fully and
run to drain. Allow the control valve to cycle on its own and return to service. This should take about 14 minutes to complete.
IMPORTANT NOTE IMPORTANT NOTE
It is normal to see milky colored water when the valve is in the backwash position (the display will read C1). If the fast rinse water continues to appear milky,
contact Technical Support Services @ 1-800-222-7880 for resolution.
Step 12: Determining Frequency of Backwash:
The frequency of backwash is factory set at 12 days. Due to the nature of any backwash fi lter it will act as a sediment reduction fi lter. If the water contains a high
sediment concentration, it is recommended to install a high fl ow inline sediment fi lter ahead of the arsenic reduction system. (Examples include the AP902 SQC
Whole House Filter). To change from factory frequency to another frequency refer to “SETTING DAYS BETWEEN REGENERATION” on page 2-5.
