2.4Introduction to Slide-In Refrigerator Service
The SIR Module is designed to mount under a Prep Table. It has two refrigerator compartment doors to provide easy access to contents, from either side. The unit FRONT is considered the side with the power switch and temp. display.
The Basics:
1)Technicians should be authorized to work on Franke Equipment and be EPA Certified and qualified to diagnose and repair refrigeration equipment.
2)This Slide-In Refrigerator Module operates on 120-volt power and is provided with a grounded plug and 8’ power cord, which typically plugs into a table outlet.
WARNING:
Unplug unit from its120-volt table mounted power source whenever servicing electrical components or removing service access panels. Failure to unplug unit may result in electric shock, burns or death.
3)The SIR refrigeration system is charged with 23 ounces (650 gm) of ozone-safe R404A refrigerant. Only use R404A refrigerant when recharging this unit.
4)A fully functional SIR will operate at safe food holding temperatures between: 34 F minimum and 40 F maximum (1 C and 4 C).
5)It is typical for this unit to take from 30 to 45 minutes to reach the normal operating temperature range, after a prolonged shutdown. The compressor will cycle on-and- off during this cool-down period.

2.5SIR Door Gasket Replacement [Part No. 3587645]
1)The Slide-In Refrigerator should be unplugged and the compartment emptied, before proceeding.
2)Open and inspect the one-piece magnetic gasket on both doors. If a gasket is torn or crushed so that it doesn’t completely seal around the full door perimeter, it should be replaced. To replace:
3)Remove the one-piece gasket from the slotted plastic extrusion built into the back of each refrigerator door. [NOTE: Plastic extrusion can be damaged using a razor knife to separate the old gasket from its retaining tailpiece. If a brittle tailpiece separates from the main gasket, remove it by pulling toward each corner using small needle nose pliers.]
4)Clean any grime from area under the old gasket.
5)Take the new gasket [P/N: 3587645] and insert the tailpiece into the gasket-mounting slot. Align the corners and start at the top of the door. Continue around the door perimeter until it is completely seated.
6)Test the replacement SIR Door Gasket by:
7)Close the door and visually check the door seal and fit.
8)Plug power cord into120-volt outlet and turn ON power switch. Allow compressor to draw down Refrigerator Compartment temperature. Check with your hand around the full door perimeter for any cold air leaks.
Tools Required:
Needle nose pliers

2.6Digital Temperature Display Replacement [Part No. 3586246]
1)Turn OFF power switch.
2)Disconnect power at table outlet. [Pull 120-Volt plug.]
3)Using a 1/8” [3-4 mm] flat blade screwdriver, remove the three screws from the temperature display bezel and pull out display assembly to extent of wire harness.
4)From inside the refrigerator compartment [bulb is mounted near evaporator cover], use a small ratchet with a Phillips screwdriver bit to loosen and remove the two screws on the temperature bulb mounting clip.
5)Remove bulb from mounting clip and pull connecting wire and bulb out through cabinet front.
6)Remove new Digital Temperature Display [P/N 3586246] from any protective packaging, uncoil 6-8” (15-20 cm) of bulb wire and insert bulb thought penetration in interior compartment wall.
7)From inside compartment pull out bulb, position down into mounting clip and secure clip to wall using two screws removed earlier. (See Photo 4 for bulb position)
