Drain Line Connection; Overflow Line Connection - Pentair Omnifilter OM34K Instructions D'installation

EQUIPMENT INSTALLATION continued
The bypass assembly connects to the water system by means
of a connector assembly . The connector is secured to the
plumbing and then inserted into the bypass . A clip is used to
hold it in place .
Figure 8 Connector Assembly
Before inserting the connector:
• Check that all O-rings are in place and not damaged .
• O-rings are pre-lubricated . Sliding surfaces should be
lubricated with 100% silicone grease .
Firmly insert connector into bypass . Press locking clip into
position . Make certain the clip is fully engaged .
NOTE: Before turning on the water to the valve, rotate the
two handles on the bypass valve 2-3 times. This
will help seat O-rings and prevent leaking.
To remove a clip:
1 . Turn off water and release water pressure at the valve .
2 . Push the water line connectors into the bypass and valve .
This will help release O-rings that may have seated in
place .
3 . Remove the clip by inserting a flat blade under the top
center of the clip and lifting (prying up) (Figure 8 Connector
Assembly) .
WARNING: Do not use pliers to remove a clip. It is likely
the clip will break.

Drain Line Connection

NOTE: Standard commercial practices are expressed here.
Local codes may require changes to the following
suggestions. Check with local authorities before
installing a system.
1 . The unit should be above and not more than 20 feet (6 .1 m)
from the drain. Use an appropriate adapter fitting to connect
1/2-inch (1.3 cm) plastic tubing to the drain line connection
of the control valve .
2 . If the unit is located 20-40 feet (6 .1-12 .2 m) from drain, use
3/4-inch (1.9 cm) tubing. Use appropriate fittings to connect
the 3/4-inch tubing to the 3/4-inch NPT drain connection on
valve .
3 . The drain line may be elevated up to 6 feet (1 .8 m)
providing the run does not exceed 15 feet (4 .6 m) and
water pressure at the softener is not less than 40 psi (2 .76
bar) . Elevation can increase by 2 feet (61 cm) for each
additional 10 psi ( .69 bar) of water pressure at the drain
connector .
8 •
4 . Where the drain line is elevated but empties into a drain
below the level of the control valve, form a 7-inch (18-cm)
loop at the far end of the line so that the bottom of the loop
is level with the drain line connection . This will provide an
adequate siphon trap .
Where the drain empties into an overhead sewer line, a
sink-type trap must be used .
NOTE: The drain line connects to the elbow previously
installed. It is located between the water line
connections at the rear of the valve.
5 . Use pliers to expand a clamp . Slide the clamp up one end
of the longer length drain line tubing about 1-2 inches and
release .
6 . Push the tubing over the ribbed drain line fitting.
7 . Expand the clamp and move it up the tube to pinch the tube
to the ftitting .
8 . Secure the discharge end of the drain line to prevent it from
moving .
Figure 9 Drain Line Connection
Waste connections or drain outlet shall be
NOTE:
designed and constructed to provide for
connection to the sanitary waste system through
an air-gap of 2 pipe diameters or
1 inch (22 mm) whichever is larger.
WARNING:
Never insert drain line directly into a
drain, sewer line, or trap (Figure 9 Drain
Line Connection). Always allow an air gap
between the drain line and the wastewater
to prevent the possibility of sewage being
back-siphoned into the softener.

Overflow Line Connection

In the event of a malfunction, the salt TANK OVERFLOW will
direct "overflow" to the drain instead of spilling on the floor. This
fitting should be on the side of the cabinet.
To connect the overflow line, locate the tubing connector on the
side of the tank (Figure 10 Tubing Connections) . Attach length
of 1/2-inch (1.3-cm) I.D. tubing to fitting and run to drain. Do
not elevate overflow line higher than overflow fitting.
Do not tie into drain line of control unit. Overflow line must be a
direct, separate line from overflow fitting to drain, sewer or tub.
Allow an air gap as per drain line instructions .
