Firmly insert connector into the valve body. Press locking clip 

into position. Make certain the clip is fully engaged.
To remove a clip:
1.  Turn off water and release water pressure at the valve.
2.  Push the water line connectors into the valve body. 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 4 Connector 

Assembly).

WARNING:

  Do not use pliers to remove a clip. It is likely 

the clip will break. 

Drain Line Flow Control

The drain line flow control (DLFC) requires assembly  

(Figures 4 and 5).

Install washer with printed 

lettering facing the valve body.

EQUIPMENT INSTALLATION 

continued

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.

4.  Use appropriate fittings to connect tubing to the DLFC 

connection on valve.

5.  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 filter 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.

6.  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.

7.  Secure the discharge end of the drain line to prevent it from 

moving.

Right Way

Figure 7  Drain Line Connection

NOTE: 

Waste connections or drain outlet shall be designed 

and constructed to provide for connection to the 

sanitary waste system through an air gap of two 

pipe diameters or one inch (22 mm), whichever is 

larger. 

WARNING:

 Never insert drain line directly into a drain, 

sewer line, or trap (Figure 7 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 filter.

Electrical Connection

WARNING:

  This valve and control are for dry location use 

only unless used with a Listed Class 2 power 

supply suitable for outdoor use.

The 363 controller operates on 12-volt alternating current 

power supply. This requires use of the an AC adapter with your 

system.
Make sure power source matches the rating printed on the AC 

adapter.
