System Installation
Pre-Installation Considerations
• A minimum of 25psi of water pressure is required for regeneration
valve to operate effectively.
• A continuous 115 volt, 60 Hertz current supply is required.
Make certain the current supply is always hot and cannot be
turned off with another switch.
• Condition of existing plumbing should be free from lime and
iron buildup. Piping that is built up heavily with lime and/or iron
should be replaced. If piping is clogged with iron, a separate
iron filter unit should be installed ahead of the water softener.
• The softener should be located close to a drain.
• Always provide for the installation of a bypass valve.
• The full weight of the plumbing system must be supported by
pipe hangers or other means.
• Do not install the system where it would block access to the water
heater, main water shutoff, water meter, or electrical panels.
• Install the system in a place where water damage is least likely
to occur if a leak develops.
• If applicable, use di-electric unions where dissimilar metals
are present.
The main control valve and all plumbing connections have
right-hand threads. Turn clockwise to install.
NOTICE
If O-ring lubricant is required, only use a silicone based
compound formulated for potable water O-ring applica-
tions. Watts recommends Ordering Code #68102757 Silicone
Lubricant. The use of other types of lubricants may attack
the control’s plastic or rubber components. Petroleum-based
lubricants can cause swelling in rubber parts, including
O-rings and seals.
NOTICE
WARNING
!
Do not exceed water pressure of 125psi (8.6 bar). Do
not exceed 110°F (43°C). Do not subject unit to freezing
conditions.
General Installation Instructions
1. Turn off water heater(s).
2. Turn off the main water supply to the building and open a treated
water faucet (cold and hot) to relieve any pressure within the
plumbing system.
3. Place the mineral tank into its final position for installation.
Make sure that the location is level and sturdy enough to sup-
port the weight of the system once it is in operation.
4. Unloaded mineral tanks will need to be loaded with resin and
gravel media following the instructions below:
4a. Inspect the distributor screen for damage, and make
sure the screen is present before loading the mineral tank
with media. Before proceeding with installation, replace any
damaged components immediately.
4b. Cap the top open end of the distributor tube with tape and
plastic sheeting to keep all media and foreign debris from
entering the distributor tube. This cap must be secure and
not come off during media loading.
4c. Place the distributor tube, screen end down, into the mineral
tank and center it in the bottom. The top of the distributor
tube should be flush with the top of the tank. Test the tape
cap to make sure it can not come off during the media
loading process.
4d. Make sure the plastic and tape cap is secure to the top of
the distributor tube, place a funnel on the top of the tank
and load first the gravel then the softening resin into the
tank. The cap must not come off of the distributor tube
during the loading of the media.
4e. Remove the funnel from the top of the tank and plastic
cap and tape from the top of the distributor tube. DO NOT
PULL UP ON THE DISTRIBUTOR TUBE when removing
the cap. The distributor tube top must remain flush with
the top of the tank.
4f. Clean any media from the threads and top of the mineral
tank. Media in the threads and on the O-ring sealing sur-
face of the tank can cause tank thread damage and pre-
vent the control valve’s O-ring seal from sealing properly.
4g. Lubricate the O-rings on the bottom of the control valve
(distributor tube port O-ring and top of tank O-ring). Use
nonpetroleum based silicone lubricant only.
4h. Place the control valve on top of the tank. When perform-
ing this step, seat the top of the distributor tube inside the
distributor port located on the bottom of the control valve
first, then press the control valve down until the control valve
threads come in contact with the tank threads. This ensures
that the distributor tube is properly seated into the bottom of
the control valve.
4i. Tighten the control valve onto the tank with a clockwise
rotation. Be careful not to cross thread the control valve to
tank connection or over tighten it. A hand tight fit is appro-
priate for the control valve torque. DO NOT use a wrench.
Tank or control valve damage could result. DO NOT apply
thread sealant or plumbing tape on the control valve to
tank threaded connection.
5. Apply a suitable thread sealant to the male threads of the flow
meter and with the meter’s direction of flow arrow pointing in
the direction of water flow, install the meter directly into the
outlet port of the system control valve.
6. Rotate meter clockwise to tighten, by gripping the meter on the
end connector that attaches to the control valve with a wrench,
and continue to tighten the flow meter end connector until tight.
Then rotate plastic meter body so the meter cable can be aligned
and inserted into the meter’s cable port. DO NOT grip on the plas-
tic meter body with the wrench when installing the flow meter.
If a 4" X 21/2" PVC tank bushing is included with the system
to adapt the control valve base to a larger control valve tank
connection, ensure the bushing is tightened, fully hand tight,
into the tank at this time.
