Location Selection; Equipment Installation - Pentair PERFORMA CV Series Service Manual

LOCATION SELECTION

Location of a water treatment system is important. The
following considerations must be taken into account when
selecting the location for the water conditioning system:
• Level platform or floor.
• Constant electrical supply to operate the controller.
• Locate drain or tub for discharge as close as possible.
• Water line connections with shutoff or bypass valves.
• Must meet any local and state codes for site of
installation.
• Do not install the unit near acid or acid fumes.
• Do not expose the unit to petroleum products.
• 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 the plastic valve to the plumbing.
• If supplementary water treating equipment is required,
make sure that adequate additional space is available.
Locate the brine tank in an accessible place so that salt
can be easily added.
• Do not install any system with less than 10' (3 m) of
piping between the outlet of the conditioners and the
inlet of the water heater. Water heaters can transfer heat
down the cold water pipe into the control valve. Hot water
can severely damage the conditioners.
• A 10' (3 m) total pipe run (including bends, elbows, etc.)
is a reasonable distance to prevent hot water damage.
A positive way to prevent hot water from flowing from a
heat source to the conditioners is to install an expandable
accumulator tank before the hot water heater. Always
conform to local codes.
Outdoor Locations
When the water conditioning system is installed outdoors,
several items must be considered.
• Moisture — The valve and 700 controller are rated
for NEMA 3 locations. Falling water should not affect
performance. The system is not designed to withstand
extreme humidity or water spray from below. Examples
are: constant heavy mist, near corrosive environment,
upwards spray from sprinkler.
This unit is for dry location use only unless used
CAUTION
with a Listed Class 2 power supply suitable for
outdoor use.
• Direct Sunlight — The materials used will fade or
discolor over time in direct sunlight. The integrity of the
materials will not degrade to cause system failures. If it
is necessary to locate the conditioner in direct sunlight, a
protective outdoor cover (P/N 1267811) over the valve and
controller is necessary.
• Temperature — Extreme hot or cold temperatures
may cause damage to the valve or controller. Freezing
temperatures will freeze the water in the valve. This
will cause physical damage to the internal parts as
well as the plumbing. High temperatures will affect
the controller. The display may become unreadable but
the controller should continue to function. When the
temperature drops down into normal operating limits
the display will return to normal. A protective cover,
P/N 1267811, should assist with high temperature
applications.
• Insects — The controller and valve have been designed to
keep all but the smallest insects out of the critical areas.
Any holes in the top plate can be covered with a metal
foil duct work tape. The top cover should be installed
securely in place.
• Wind — The Logix cover is designed to withstand a 30
mph (48 Kph) wind when properly installed on the valve.

EQUIPMENT INSTALLATION

All plumbing must conform to local codes. The two tanks
should be plumbed to an interconnecting manifold (see Figure
1 Typical Plumbing for Twin Tank Systems below). It is highly
recommended that separate brine lines be used for each tank.
It is critical for the resin, resin volume, inlet piping, etc. to be
identical for both tanks.
