CAUTION
To reduce the risk associated with property damage due to water leakage:
• Do not use a torch or other high temperature sources near fi lter system, cartridges, plastic fi ttings or plastic plumbing.
• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic.
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur if over tightening occurs.
IMPORTANT NOTE
If installation is to be a split stream prior to media tank (Figure 1) refer to Special Service Instructions following STEP 14.
Step 6
Attach drain line to drain line fi tting. To prevent back pressure from reducing fl ow rate below minimum re-
quired for backwash, the 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 your local pluming code prior to installation.
Step 7
Position drain line over drain and secure fi rmly. To prevent back-siphoning of sewer water, provide an air-gap
of at least 2 in. or 2 pipe diameters between end of drain hose and drain (Figure 5). Do not raise drain line
more than 10 ft. above fl oor.
Step 8
CAUTION CAUTION
To reduce the risk associated with skin, eye, and respiratory tract irritation from water treatment chemicals:
• Several types of water treatment chemicals may be used in this product, depending upon the application. During installation and use, exposure may cause irritation to
skin, eyes, and respiratory tract.
• Utilize a NIOSH-approved dust fi lter mask, protective gloves, and appropriate eye protection when handling and pouring water treatment chemicals.
• To request an MSDS relating to the media included with this product, call 203-238-8965 or go to www.3M.com, select country, and use the search engine to search
MSDS. For emergencies, call 800-364-3577 or 651-737-6501 (24 hours).
Pour two (2) gallons of sulfur reduction media into the solution tank. Under most operating conditions sulfur reduction media should be diluted with an equal amount
of sulfur-free (preferably soft) water. In some situations, however, where a high sulfur concentration and/or a high pumping rate exists, the sulfur reduction media
must be used in undiluted form in order to provide a high enough feed rate to precipitate all the sulfur. To determine if the sulfur reduction media should be diluted
or undiluted, multiply the pumping rate of your well pump by the Hydrogen sulfi de gas (H
2
S) concentration as determined by your water analysis (Page 2-1):
Pumping Rate ______ x Hydrogen Sulfi de (H
2
S) ______ = __________
(gpm) (ppm) (Number)
* Refer to CHECK YOUR WATER PRESSURE PUMP RATE, Section 2 for proper method of determining pumping rate.
If the resulting number is less than 90, dilute the sulfur reduction media with an equal amount of water. If the number is 90 or above, do not dilute the sulfur reduc-
tion media. (EXAMPLE: 8 gpm pumping rate x 8 ppm sulfur = 64. 64 is less than 90 - therefore, dilute the sulfur reduction media with an equal amount of water
free of hydrogen sulfi de gas. This is the starting point for setting the correct feed rate).
Step 9
Normally the feed pump operates only when the well pump runs; however, to facilitate calibrating the feed pump, remove the feed pump power cord from the special
receptacle controlled by the pressure switch and plug it into any 110/115V power sourc. To prime pump, turn knob on bleed valve to “BLEED” position and allow
pump to run until solution appears in bleed return line. Turn knob on bleed valve to “PUMP” position and continue running feed pump until discharge tube fi lls to
injection assembly, then plug feed pump power cord into special receptacle controlled by the pressure switch.
