Start-Up Operation

Single System With Multiple Evaporators

•Check all wiring connections to be sure they are correct and tight.

•On the condensing unit

-Check the setting of time delay relay. It should be set at 1 minute (the second marker).

-Check the low pressure switch setting on freezer units. It must be set to 0 psig cut-out, 10 psig cut-in to allow positive start and operation, especially in cold ambient. This can be changed to a higher value in warmer climates. On cooler units, the low pressure switch has a fixed setting and cannot be adjusted.

•Turn power on.

•On the MASTER evaporator

-DO NOT REMOVE the room sensor from any evaporator

-Use the “PROGRAM REVIEW” button to scroll through settings.

-Check “rEF” (Refrigerant Type). Factory defaults are: air defrost R-22, electric defrost R-404A.

Change to the refrigerant being used.

-Check “bot” (Box Temperature). Factory defaults are: air defrost 35°F and electric defrost –10°F.

Change to the desired temperature.

-Review and change other setting if necessary.

-See procedures below on how to change settings.

•On the SLAVE evaporators. All Beacon II boards are shipped with the factory default as a “MASTER” evaporator.

-DO NOT REMOVE the Room Sensor from any evaporator

-Each SLAVE Evaporator must be

changed to identify it as a SLAVE. Use the “PROGRAM REVIEW” button to scroll until “SLA” appears, then use the “SELECT” knob to select

“YES” then press “ENTER.”
