Thermostat installation and wiring of the E.I. 600
Installation of temperature control
This ice machine uses a Ranco ETC control. We recommend mounting in an accessible location
near the unit. Since this control has an LED indictor and switches which can be useful in
monitoring and testing the ice machine, a convenient location is preferred. A clean dry location
in the engine room is also acceptable, perhaps on a bulkhead near the ice machine.
See trouble shooting item #8.
Installation of the sensor
Locate the sensor just below the ice delivery hose and slightly to the left or right, approximately one
inch below the thru-hull and one inch off the center line. (This is to avoid having water and ice
hitting sensor on the way into the box.) See drawings #4 and #5. Drill a 3/8" hole in storage box to
pass sensor through. See full size yellow template in SP-32 box. Fasten sensor to inside of box with
stainless steel cover provided. This will cover the whole, upper third of sensor and wires. Fasten
cover down with two screws. If sensor will not have to be removed in lifting out storage box, it may
be caulked in place. See drawings #4, 5, and 6.
Temperature control wiring
See wiring diagram G901001 included in this manual.
Wear prevention check
Check all metal tubing to see that there is no contact. Contact might cause excessive wear when
machine is operating, thus causing a refrigerant leak. Tubes can be tapped to listen for contact. Pay
particular attention to tubes from pressure controls in electrical box.
