•
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;
•
existing plumbing should be in a good shape and free from limescale. In case of doubt, it is
preferable to replace it;
•
all plumbing must be completed according to local codes and installed without tension or
bending stresses;
•
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;
•
do not use lead-based solder for sweat solder connections;
•
the riser tube should be cut 5 to 7 mm below the top of the tank. Slightly bevel the ridge in order
to avoid deterioration of the seal whilst fitting the valve;
•
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 (7 gpm) or the pipe length is greater than 6 m
(19 ft 8 in);
•
do not support the weight of the system on the 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 drain elbow, and other NPT/BSP threads;
•
the installation of a prefilter is always recommended (100μ nominal);
•
valve inlet/outlet must be connected to main piping via flexible.
5.4. Integration
constraints
Location of a water treatment system is important. The following conditions are required:
•
flat and firm 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 to prevent backup of hot water into system;
•
always install check valve before water heater 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.
