5.2.3. Mechanical
• Do not use petroleum-based lubricants such as vaseline, oils, or hydrocarbon-based lubricants.
Use only 100% silicone lubricants.
• All plastic connections should be hand tightened. PTFE (plumber’s tape) may be used on
connections that do not use an O-ring seal. Do not use pliers or pipe wrenches.
• All plumbing must be completed according to local codes.
• Soldering near the drain line should be done before connecting the drain line to the valve.
Excessive heat will cause interior damage to the valve.
• Observe the drain line requirements:
Maximum 1 m (3 ft 3 in) high at 2 bars (29 psi) inlet pressure. Add 50 cm (1 ft 7 in) for each
additional 1 bar (14.5 psi) inlet pressure.
• Do not use lead-based solder for sweat solder connections.
• The drain line must be a minimum of 12.7 mm (½") in diameter. Use 19 mm (¾") pipe if the
backwash flow rate is greater than 26.5 lpm (5.83 gpm) or the pipe length is greater than 6 m
(19 ft 8 in).
• Do not support the weight of the system on the control valve fittings, plumbing, or the bypass.
• It is not recommended to use sealants on the threads. Use PTFE (plumber’s tape) on the threads
of the 25.4 mm (1") NPT elbow, the drain line connections, and other NPT/BSP threads.
5.3. Integration constraints
Location of a water treatment system is important. The following conditions are required:
• Level platform or floor;
• Room to access equipment for maintenance and adding brine (salt) to tank;
• Constant electrical supply to operate the controller;
• Total minimum pipe run to water heater of 3 m (10 ft) to prevent backup of hot water into system;
• Always install check valve to protect the softener from hot water return;
• Local drain for discharge as close as possible;
• Water line connections with shut off or bypass valves;
• Must meet any local and state codes for site of installation;
• Valve is designed for minor plumbing misalignments. Do not support weight of system on the
plumbing;
• Be sure all soldered pipes are fully cooled before attaching plastic valve to the plumbing.
