General Installation Warnings
The following general warnings should be observed when
installation and/or general service maintenance is performed.
• Plumbing connections should be done in
accordance with state and local plumbing codes.
• Do not use with water that is microbiologically
unsafe or of unknown quality without adequate
disinfection before or after the system.
• Drain lines should be ” minimum for drain line
flows up to 7 gpm. Flows above 7 gpm or runs in
excess of 20 feet require ” drain line.
WARNING: Never connect drain line directly into a drain, sewer line or
trap. Plumbing code requires installation to allow an air gap* between the
drain line and the wastewater to prevent the possibility of sewage back-
siphoning into the conditioner. (See Figure 6.) Sewage backup can have
harmful health effects.
* Plumbing code air gap is one inch above the flood plane.
• All electrical connections must be connected
according to local codes. The electrical source
must be uninterrupted. Install grounding strap on
metal pipes.
• Do not use pipe dope or other types of liquid
sealants on any threads. Teflon tape must be used
on the drain line ” threads and also on the
3
/8”
brine-line connections.
Note: Factory has teflon taped these fittings.
• Use caution if soldering inlet, outlet, or drain lines.
Excess heat will damage the control valve and/or
bypass valve.
• A Brine Tank over-flow line of ” ID
5
/8” OD is
recommended for the brine tank. This line should
run from the barb fitting on the side of the tank to
an unobstructed drain. (See Figure 7.)
• Each system comes standard with a high-pressure
injector.* It may be necessary to change the
injector (see Figure 8) to match your incoming
water pressure. (See Table 2 for injector sizes.)
