Basic Installation and Start up Procedures
Installation Instructions
1.Prepare the Media Tank.
a.Place the Media tank where you want to install the system making sure the tank is plumb and on a firm base.
b.During cold weather warm the valve to room temperature before installing.
c.Perform all plumbing according to local plumbing codes. Drain line size should be the same as the drain line flow control. A vacuum relief valve is recommended.
d.If needed glue distributor basket to one end of the distributor tube.
e.Place tube with basket into center of tank and if needed, cut the distributor tube flush with top of tank (A) and deburr the outside of the tube (B) after cutting.
f.Lubricate the distributor 0 ring seal (C) and tank 0 ring seal. Use only silicone based lubricant.
g.Temporarily block top opening of distributor tube to prevent media from entering the tube while filling tank.
h.Load media keeping distributor basket and tube centered in tank. When using multiple media be sure to load in the recommended order.
i.Remove temporary block from distributor tube.
2.Install 7G2x Control Valve and position Media Tank.
a.If a locking upper distributor basket is included with your system place and lock the distributor to the bottom of the valve.
b.Place the valve over the distributor tube and spin the valve onto the tank
ensuring the threads are not cross threaded. Rotate the valve freely without force until it comes to a stop. Rotate valve an additional ¼ to ½ turn. The valve is now properly tightened.
c.If needed, rotate or reposition the tank with unit to its final position.
NOTE:
All soldering MUST be done on any connections requiring soldering prior to connecting the main control. The main control will be damaged if it is connected at the time of soldering.
3.Connect Plumbing and electrical.
a.Make plumbing connections to Inlet, Outlet and drain fittings on valve assembly. A vacuum relief valve is recommended. Note: Teflon tape is the only sealant to be used on valve fittings.
b.If the buildings electrical system is grounded to the plumbing make certain ground is continuous after installation. Plumbing must be done in accordance with all applicable local codes.
c.Place unit Bypass into the Bypass Position (see page 21) and slowly turn on the main water supply and check for leaks.
d.Slowly open a cold treated water tap nearby and let water run a few minutes or until the system is free of foreign material resulting from the installation. Close the water tap when water runs clean.
e.Plug the valve into an approved un switched power source. NOTE: make all electrical connections according to codes.
4.Prepare and connect Brine Tank (7G2i controls only).
a.Make sure the floor is clean below the Brine (salt) Tank location and that it is level. Since salt must be periodically added to the brine tank it should be located where it is easily accessible.
b.Place approximately 1” of water above the grid plate. If a grid is not utilized, fill to the top of the Air Check (see page 8) in the salt tank. Do not add salt to the brine tank at this time.
c.Install the ⅜” O.D. Polyethylene tube from the brine line fi ng on the 7G2i Control Valve to the brine valve (see page 22) on in the brine tank.
d.An overflow drain line is recommended where a brine overflow could damage furnishings or the building structure. Your CASCADIAN® system is equipped with a brine tank safety valve which greatly reduces the chance of an accidental brine overflow. In the event of a malfunction an overflow line connection will direct the “overflow” to the drain instead of spilling on the floor where it could cause considerable damage. This connection is an elbow fitting on the side of the brine tank.
i.Attach a length of ½” I.D. tubing to the fitting and run to drain.
ii.Do Not elevate overflow line to more than 3” below the bottom of the fitting.
iii.Do Not connect this tube to the drain line of the control valve. Overflow line must be a direct separate line from fitting to drain.
iv.Allow an air gap.

5.Bring the system online.
a.Manually cycle the 7G2i control valve to the Backwash Position (see page 10). Open the inlet side of the Bypass just enough to hear water flow and air escape the unit and let the water flow slowly into the media tank until the air is purged from the unit. After air is purged slowly open the Bypass inlet all the way.
b.7G2i Controls Only:
i.Manually step the valve to the Brine Draw position (see page 10), verify water is being drawn from the brine tank and allow the valve to draw water from the brine tank until it stops. NOTE: The air check will check at approximately the midpoint of the screened intake area.
ii.Manually step the valve past the 2nd Backwash and Rapid Rinse cycles to the Brine Tank Fill cycle (see page 10), verify water is being added to the brine tank and allow the valve to return to In Service automatically.
iii.With the valve In Service, check that there is at least 1" of water above the grid in the brine tank (if a grid is used) or to the top of the Air Check.
iv.Fill the brine tank with salt and place cover on tank. Solar salt in pellet form is recommended, DO NOT use rock salt.
6.Open the Bypass outlet and manually initiate a regeneration cycle.
a.Clean filter media: If your systems is a filter with the 7G2b control the media contains fines that must be backwashed out of the media, continue backwashing the unit until backwash water running to drain is clear. Gently tap the side of the tank while in backwash cycle just enough to vibrate the media. Caution: Tapping too hard may damage the media tank, a damaged tank do to excessive force will not be warranted. If tapping the side causes the backwash water turn color wait till it runs clear again and repeat this process until it does not turn color after tapping. This step is essential for proper installation and system function, it must not be skipped.
b.After a complete regeneration your CASCADIAN® softener / filter unit is now in service.
7.Inform owner about reading operating and display instructions. Point out that the clock may need to be re set if the power goes out and will need to be reset for changes in daylight savings time.
