MODEL 6700 Downflow
General Residential Installation Check List
WATER PRESSURE: A minimum of 25 pounds of water pressure is required for regeneration valve to operate
effectively.
ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is required. Please make sure your
voltage supply is compatible with your unit before installation.
EXISTING PLUMBING: Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up
heavily with line 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.
LOCATION OF SOFTENER AND DRAIN: The softener should be located close to a clean working drain and
connected according to local plumbing codes.
BY-PASS VALVES: Always provide for the installation of a by-pass valve if unit is not equipped with one.
CAUTION: Water pressure is not to exceed 120 p.s.i., water temperature is not to exceed 110°F, and the unit cannot
be subjected to freezing conditions.
Installation and Start-up Procedures
1. Place the softener tank where you want to install the unit, making sure the tanks are level and on a firm base.
2. During cold weather it is recommended that the installer warm the valve up to room temperature before operating.
3. All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain should be a
minimum of 1/2
″
. Backwash flow rates in excess of 7 gpm or length in excess of 20
′
require 3/4
″
drain line.
4. The 1
″
distributor tube (1.050 O.D.) should be cut flush with top of each tank. Note: Only use silicone lubricant.
5. Lubricate the distributor O- ring seal and tank O- ring seal. Place the main control valve on tank.
6. Solder joints near the drain must be done prior to connecting the Drain Line Flow Control fitting (DLFC). Leave at
least 6
″
between the DLFC and solder joints when soldering pipes that are connected on the DLFC. Failure to do
this could cause interior damage to DLFC.
7. Teflon tape is the only sealant to be used on the drain fitting.
8. Make sure that the floor is clean beneath the salt storage tank and that it is level.
9. Place approximately 1
″
of water above the grid plate. If a grid is not utilized, fill to the top of the air check in the salt
tank. Do not add salt to the brine tank at this time.
10. On units with a by-pass, place in by-pass position. Turn on the main water supply. Open a cold soft water tap
nearby and let run a few minutes or until the system is free from foreign material (usually solder) that may have
resulted from the installation. Once clean, close the water tap.
11. Place the by-pass in service position and let water flow into the mineral tank. When water flow stops, slowly open a
cold water tap nearby and let run until the air is purged from the unit.
12. Plug the valve into an approved power source. Once the valve is powered it will drive to the Service Position.
