700-2 TALL UNIT SEALED SYSTEM
COMPONENTS
Upper Refrigerator Compartment Evaporator
Removal (700TCI-2, 700TR-2)
The upper refrigerator evaporator in the model 700TC/I-2
and 700TR-2 is concealed by the evaporator cover and
is attached to the back wall with screws.
NOTE:
Before attempting to remove the evaporator,
evacuate the refrigerant from the sealed system.
To access and remove the upper evaporator, first
remove the light diffuser and evaporator cover. Then,
extract the screws securing the thermistor to the evapo-
rator and the evaporator to the back wall. With a tube
cutter, cut the inlet tube approximately one inch from the
end and cut the outlet tube approximately two inches
from the end.
NOTE:
Sweating the joints apart is not recommended
as this may induce moisture into the sealed system and
could cause a solder restriction in the capillary tube.
NOTE:
When installing a new evaporator, be sure to
thoroughly clean the tubing before brazing. After brazing
and inspecting the joint for leaks, it is recommended to
apply an acrylic-based paint to the joints to protect the
exposed metals from oxidation.
Lower Compartment Evaporator Removal
(All Tall Units)
The lower evaporator in the tall units is concealed by the
evaporator cover and is attached to the back wall with
screws.
NOTE:
Before attempting to remove the evaporator,
evacuate the refrigerant from the sealed system.
To access and remove the lower evaporator, first remove
the heat exchanger cover, evaporator cover and switch
enclosure. In the model 700TC/I-2, the evaporator fan
shroud will also need to be removed.
(If reusing the
existing defrost heater, defrost terminator and evaporator
thermistor, they can be removed from the evaporator
after it is removed from the unit.)
Then, extract the
screws securing the evaporator to the back wall. With a
tube cutter, cut the inlet tube approximately one inch
from the end and cut the outlet tube approximately two
inches from the end.
NOTE:
Sweating the joints apart is not recommended
as this may induce moisture into the sealed system and
could cause a solder restriction in the capillary tube.
