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 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.
Check for voids and ensure sealing compound
completely fills the space.

STEP 3. Silicone Seal (RTV type)
Check for complete silicone seal of:
• Joint where rear wall meets ceiling
• Around evaporator coil compartment
STEP 4. Floor Drain
Check that interior floor drain plug is in place if not
plumbed to external drain and completely
tightened. Figure 6-2.
Check that the evaporator condensate trap is
looped and full of water. Figure 6-3.
