Component Access/Removal
Condenser Removal (All Base Units)
The condenser is secured to the unit tray by four rivets
that pass up through the unit tray into the condenser
side brackets.
NOTE: Before attempting to remove the condenser,
evacuate the refrigerant from the sealed system.
To remove the condenser, the kickplate/grill will need to
be removed first. Then, extract the two screws that
secure the unit tray to the unit and slide the tray out
(See Figure 7-49).
NOTE: It will be necessary to disconnect the compres-
sor electrical leads in order to pull the tray out far
enough to remove the condenser.
To Remove the condenser (See Figure 7-50):
1. Cut condenser inlet and outlet tubes to and from
the condenser, approximately one inch (25 mm)
from weld joints.
2. Prop front of unit tray up.
3. Drill out rivets securing condenser to tray.
NOTE: Sweating the joints apart is not recommended
as this may induce moisture into the sealed system.
NOTE: The high-side filter-drier must be replaced
whenever replacing the condenser.
NOTE: When installing the replacement condenser, be
sure to thoroughly clean the tubing before brazing.
