Installing alarm
1. Mount alarm in desired location with screws (supplied
by others) through back of housing. Do not place
undue strain on probe cable.

not measure temperature correctly if wire length is
changed.
2. Plug power cord into 110 outlet.
3. Push center tab of short bottle bracket into top of rear
left pilaster (Fig. 15).
Note: Use longer bottle bracket for REF5 refrigerators
using cut-out upper shelf accessory.
4. Fill bottle with glycerin or other liquid to increase
accuracy of readings by simulating the internal
temperature of medications.
5. Insert bottle into bottle bracket.
6. Route probe through hole in refrigerator back and push
probe down through gasketed bottle top.
Note: Alarm probe must be placed in bottle for
proper system operation. Refer to Fig. 16 if attaching
