Installation
All plumbing must conform to local codes.
Inspect unit carefully for carrier shortage or shipping damage.
Location Selection
1. The distance between the unit and a drain should be as short as possible.
2. If it is likely that supplementary water treating equipment will be required, make
certain adequate additional space is available.
3. Since salt must be added periodically to the brine tank, the location should be
easily accessible.
4. Do not install any unit closer to a water heater than a total run of 10 feet (3 m) of
piping between the outlet of the conditioner and the inlet to the heater. Water
heaters can sometimes overheat to the extent they will transmit heat back down
the cold pipe into the unit control valve.
Hot water can severely damage the conditioner. A 10-foot (3-m) total pipe run,
including bends, elbows, etc., is a reasonable distance to help prevent this
possibility. A positive way to prevent hot water from flowing from heat source to
the conditioner, in the event of a negative pressure situation, is to install a check
valve in the soft water piping from the conditioner. If a check valve is installed,
make certain the water heating unit is equipped with a properly rated
temperature and pressure safety relief valve. Also, be certain that local codes
are not violated.
5. Do not locate unit where it or it’s connections (including the drain and overflow
lines) will ever be subjected to room temperatures under 34
o
F (1
o
C) or over 120
o
F
(49
o
C).
