Defrost Terminator Removal
(700TC/I-2, 700TF/I-2, 700TF/I-2V)
The defrost terminator in the 700TC/I-2, 700TF/I-2 and
700TFI-2V is attached to the second tubing pass from
the top of the evaporator.
To access and remove the defrost terminator, first
remove the two drawers, the heat exchanger cover, the
evaporator cover and the evaporator fan shroud. Then,
remove the screws at the top of the evaporator and pull
the top of the evaporator forward slightly. Disconnect
the defrost terminator electrical leads and pull the termi-
nator towards the back of the unit so that the clip disen-
gages from the evaporator tubing.
NOTE:
When reinstalling the defrost terminator, it must
be attached to the second tubing pass of the evaporator.
Installing the terminator on the first pass will place it too
close to the defrost heater, causing shortened defrost
times which will lead to incomplete defrost.
Defrost Heater Removal
(700TC/I-2, 700TF/I-2, 700TF/I-2V)
The defrost heater in the 700TC/I-2, 700TF/I-2 and
700TFI-2V is pressed into the evaporator fins at the
front. Heater clips are then hooked from one evapora-
tor tube to another, over the heater.
To access and remove the defrost heater, first remove
the two drawers, the heat exchanger cover, the evapo-
rator cover and the evaporator fan shroud. Then, dis-
connect the heater electrical leads. Grab the return
bend of the heater clips with a needle-nose pliers and
pull that end of the clip away from the evaporator.
Unhook the other end of the heater clip from the evapo-
rator tubing. Cut the heater wire near the electrical
connector and pull the heater from the evaporator.
NOTE:
When installing replacement heater, do not place
heater clips over top heater pass. Doing so will interfere
with evaporator fan shroud.
Switch Enclosure Assembly Removal (All Tall Units)
The switch enclosure assembly is held in the back right
corner of the lower compartment with screws, one at
the top and bottom left corners, and depending on the
model, one or two along the right side.
To access and remove the switch enclosure assembly,
first remove the two drawers, the heat exchanger cover,
the the evaporator cover, as well as the drain trough
heater on applicable models. Then, disconnect all elec-
trical leads from at the top left side of the enclosure.
On applicable models, the fill tube and fill tube heater
assembly will also need to be pulled from the right wall.
Extract the switch enclosure mounting screws and pull
the assembly from the back wall.
