Sweep floor clear of nuts, bolts and other protrusions which
may damage the unit.

Do not drop or jar the filter carton.

1. Remove new filter from carton

a. Place carton on floor.
b. Tilt the carton on one corner. Handle the carton at opposing corners.
c. Remove sealing tape and fold back flaps of carton.
d. Gently upend the filter to place the exposed end of the filter on the floor. Do not jar the

filter.

e. Pull the carton from the filter unit. Be careful to not pull the filter from the carton.

2. Inspect the filter.

a. Visually inspect the new gasket(s) for damage during handling.
b. Use a strong lamp to examine the exposed areas of both faces for evidence of breaks,

cracks, or pinholes (Figure 10).
If a strong lamp is unavailable,
use a flashlight in a darkened
room.

c. Look for visible defects with

the light projected along the
full length of each channel
created by the separators.
Translucent spots may not
necessarily indicate holes or
cracks but may simply be
variations in thickness of the
filter medium.

d. Check that the adhesive seal

around the filter unit faces are
complete and unbroken.

e. Check frame corner joints for

adhesive sealing and tightness.

f. Check that gaskets are

cemented firmly to the filter
frame and that gasket pieces
are undamaged and butted or
mated at the joints.

Notice

Do not attempt to repair a damaged filter unit

—particularly the

medium. Any unit so repaired must be retested to assure that
hidden damage does not exist which might reduce filtering
efficiency. Repair and retest is not economical for most users.
