STEP 1:
Carefully remove all components from packaging. DO NOT DISCARD PACKAGING until all
water softener components and fittings have been located.
STEP 2:
Use clips and screws provided and attach bypass valve to the inlet/outlet of the control valve.
See figure 2 below.
IMPORTANT: Mechanical metered (NMS Series) units require the installer to insert the meter cable into
the top of the meter module.
STEP 3:
Place unit at desired installation position.
DO NOT plug into electrical outlet at this time
(see STEP 15 on page 6 or see STEP 10 on page 5). DO NOT put salt in the brine tank at
this time (see STEP 14 on page 6).
STEP 4:
Shut off water at main supply. Relieve pressure by opening nearest faucet. On private well
systems, turn off power to pump and drain pressure tank.
SHUT OFF POWER OR FUEL
SUPPLY TO WATER HEATER
.
STEP 5:
Cut main supply line as required
to fit plumbing to inlet and outlet of bypass valve.
DO NOT
PLUMB INLET AND OUTLET BACKWARDS
. Piping should be supported. Do not apply
heat to any fitting attached to the bypass or control valve.
STEP 6:
Use polyethylene drain line tubing provided (
NO VINYL TUBING
) to run drain line from control
valve discharge fitting to floor drain or sump pit capable of handling the backwash rate of the
softener (refer to specifications and flow rate on page 12).
DISCHARGE END OF THE
DRAIN LINE MUST BE FIRMLY SECURED!
There must be an air gap at the end of the
drain line to prevent siphoning of waste water and meet plumbing code. Total length of drain
line should be
15’ or less. AVOID OVERHEAD DRAINS.
