6.1 Air Infiltration
Air infiltration can occur in several locations.
NOTE: Unit may manifest longer than normal
run times caused by the additional loads that air
infiltration presents.
Signs of air infiltration include:
• Presence of water, moisture or ice
Condensation on glass or metal surfaces
•
STEP 1 - Door Gaskets
Check door gaskets for rips, cracks, or other
damage.
The door gasket should be pushed in firmly and lay
flat.
Ensure gasket forms a complete seal around the
door.
STEP 2 - Sealing Compound
Sealing compound is used to seal wiring and line
set pass-through between the condenser and the
evaporator compartments. See Figure 6-1.1 and
6-1.2.
Additionally, sealing compound is used to seal door
switch wiring pass-through holes at top of cabinet.
See Figure 6-1.3 and 6-1.4.
Check for voids and ensure sealing compound
completely fills space (both on interior and exterior
openings (if both tubes and wires pass-through and
opening, ensure sealing compound is used between
the items).
