Water Line Connections
Detergent Valve
1. Connect 1/4” O.D. flexible copper tubing from the building water supply
to the inlet side of the solenoid valve, located at the bottom of the Apex2
I/O enclosure.
2. Connect 1/4” O.D. flexible copper tubing from the outlet side of the
solenoid valve to the Apex Detergent Dispenser.
Note: Refer to the Installation and Operation Manual of the Apex Detergent
Dispenser for water temperature and flow rate requirements.
Pressure Switch (Optional)
If the dishmachine does not offer a separate rinse signal to activate the rinse
additive, a pressure switch will need to be installed. The rinse injector will then
be activated when the switch closes from the pressure created by the flow of
the final rinse water.
1. Locate hexagon feature on the bottom of the I/O enclosure, located in
front of the detergent valve. See figure 4.10.
2. From the outside of the enclosure, knock out the plastic piece that covers
this hexagon hole.
3. From the inside of the enclosure, insert pressure switch in the hexagon
hole. Secure pressure switch using mounting nut.
Note: See Figure 4.11 for wiring instructions.
4. Connect 1/4” copper tubing between the pressure switch on the outside of
the enclosure and the injection fitting on the final rinse line.
Note: Pressure switch is not included in the installation kit, order if needed.
