General Installation - NOVO NVO465-100 Operating Manual

Control Operation During A Power Failure
In the event of a power failure, the valve will keep track of the time and day for 48 hours. The programmed settings are
stored in a non-volatile memory and will not be lost during a power failure. If power fails while the unit is in regeneration,
the valve will finish regeneration from the point it is at once power is restored. If the valve misses a scheduled regeneration
due to a power failure, it will queue a regeneration at the next regeneration time once power is restored.

General Installation

1) Locate the softener tank and brine tank close to a drain where the system will be installed. The surface should be clean
and level.
2) Perform all plumbing according to local plumbing codes.
a) Use a ½" minimum pipe or tubing size for the drain line
b) Use a ¾" pipe or tubing for backwash flow rates that exceed 7 gpm or length that exceeds 20ft (6 m)
c) ON COPPER PLUMBING SYSTEMS BE SURE TO INSTALL A GROUNDING WIRE BETWEEN THE INLET AND OUTLET
PIPING TO MAINTAIN GROUNDING.
3) Any solder joints near the valve must be done before connecting any piping to the valve. Always leave at least 6" (152
mm) between the valve and joints when soldering pipes that are connected to the valve. Failure to do this could cause
damage to the valve.
4) If the valve is not installed on the tank, cut the 1" central pipe flush with top of each tank. Lubricate the large o-ring on
the valve that seals against the tank. Screw the valve on to the tank. Be careful to not cross thread the valve into the
tank. Only use silicone lubricant.
5) Connect the drain hose to the valve and secure it with a hose clamp. Run the drain hose to the nearest laundry tub or
drain pipe. This can be ran up overhead or down along the floor. If running the drain line more than 20 ft overhead, it
is recommended to increase the hose size to 3/4". NEVER MAKE A DIRECT CONNECTION INTO A WASTE DRAIN. A
PHYSICAL AIR GAP OF AT LEAST 1.5" SHOULD BE USED TO AVOID BACTERIA AND WASTEWATER TRAVELLING BACK
THROUGH THE DRAIN LINE INTO THE SOFTENER.
6) Connect the brine line from the valve to the air check / safety elbow as per figure 7. Double check to make sure all
connections are assembled correctly and the brass and plastic nuts are tight and secure to prevent leaks.
7) Add water until there is approximately 1" (25 mm) of water above the grid plate. If the tank does not have a grid, add
water until it is above the air check in the brine tank. Do not add salt to the brine tank at this time.
8) Place the unit in the bypass position.
