COMPONENT ACCESS AND REMOVAL
This section explains how to adjust, access and/or remove Under Counter Series components. If different models
have similar procedures, they are grouped together under the appropriate heading. The units covered in the proce-
dures are listed between brackets after the heading.
An attempt has been made to arrange these procedures in such a way as to simulate which components would
need to be removed first in order to gain access to other components. When following a component removal proce-
dure, it may be necessary to reference another component removal procedure listed earlier in this section.
This section is arranged as follows: .............................................................................................................. Page:

NOTE: Before continuing, please take note of the WARNINGS and CAUTIONS below.
•IF IT IS NECESSARY TO REMOVE A UNIT FROM ITS INSTALLATION, REMEMBER THAT THE UNIT
COULD TIP FORWARD WHEN PULLED FORWARD BEYOND THE ANTI-TIP COMPONENTS, RESULTING
IN SERIOUS INJURY OR DEATH. PULLING A UNIT FROM ITS INSTALLATION SHOULD ONLY BE PER-
FORMED BY AN AUTHORIZED SERVICE TECHNICIAN OR INSTALLER.
•TO AVOID ELECTRIC SHOCK, POWER TO THE UNIT MUST BE DISCONNECTED WHENEVER ACCESS-
ING AND/OR REMOVING COMPONENTS POWERED BY ELECTRICITY OR COMPONENTS NEAR OTHER
ELECTRICAL COMPONENTS. IF THE UNIT IS PLUGGED IN, BUT HAS NOT BEEN SWITCHED ON BY
PRESSING THE POWER KEY, AC VOLTAGE IS STILL PRESENT AT THE MAIN CONTROL BOARD.
•IF REMOVING A DOOR REMEMBER THAT DOORS ARE HEAVY. IF THEY WERE TO FALL, THEY COULD
CAUSE SERIOUS PERSONAL INJURY.
•If working in the compressor area, remember that compressor and tubing may be hot.
•If working on or around the evaporator or condenser, remember that evaporator and condenser fins are
sharp.
