Checking for Leaks
Over time, fittings can loosen as the unit is used and moved. During normal
use, inspect the unit for leaks at a minimum of every three months (or as
specified by current federal, state, and local regulations). Use the following
steps to check the unit for leaks.
NOTE: The manufacturer does not reimburse for lost refrigerant.
1. Remove the power cord from the outlet.
High voltage electricity inside the unit has a risk of electrical shock. Disconnect
the power before opening the back door or servicing the unit.
2. Remove the four screws that secure the hood.
3. Remove the hood.
4. Open the back door of the unit’s protective covering, and lift the door off
the unit. To unlock the door, turn the two screws 1/4 turn counterclockwise.
5. Remove the five screws that secure the front section of the unit’s
protective covering, and remove the covering.
6. Use a leak detector to trace all lines, and check all connections for
refrigerant leaks. Tighten any fittings or connections if a leak is indicated.
7. Replace the unit’s protective covering as follows:
a. Replace the front section, and replace the five screws that secure the
covering.
b. Replace, close, and lock the back door. To lock the door, turn the two
screws 1/4 turn clockwise.
c. Replace the hood and the four screws that secure the hood.
DO NOT use compressed air to pressure test or leak test the unit. Some mixtures of
air and refrigerant are combustible at elevated pressures. These mixtures are
potentially dangerous and may result in fire or explosion.
