Installation Instructions
TURN OFF WATER SUPPLY
1. Close the main water supply valve, located near the
well pump or water meter.
2. Shut off the electric or fuel supply to the water
heater.
3. Open all faucets to drain all water from house pipes.
NOTE: Be sure not to drain water from the water
heater, as damage to the water heater ele-
ments could result.
ASSEMBLY
1. Viessmann softeners are factory assembled. During
installation, remove the salt lid and set it aside to
prevent damage. Check the brinewell to be sure it
is secured and vertical (See Figure 11). Slide the
faceplate cover forward to expose the softener valve
assembly.
2. Lift the brine valve out of the brinewell. Make sure
the float stem is parallel to the stand tube so the
seals will seat properly during operation. Place the
brine valve back into the bottom of the brinewell and
reinstall the brinewell cover.
3. Install the brine tank overflow grommet and elbow
into the 2 cm diameter hole in the back of the salt
storage tank wall.
MOVE THE UNIT INTO PLACE
1. Move the water softener into the desired location.
Set it on a solid, level surface.
IMPORTANT: Do not place shims directly under the
salt storage tank to level the softener.
The weight of the tank, when full of
water and salt, may cause the tank to
fracture at the shim.
