System Requirements - Whirlpool COMMERCIAL DRYERS Installation Instructions Manual

EXHAUST SYSTEM REQUIREMENTS
1. CAUTION: FOR YOUR PERSONAL SAFETY DO NOT
EXHAUST DRYER INTO A CHIMNEY, FURNACE COLD
AIR DUCT OR ANY OTHER COMMON DUCT, ATTIC OR
CRAWL SPACE. ACCUMULATED LINT COULD BECOME
A FIRE HAZARD OR MOISTURE COULD CAUSE DAM-
AGE.
DO NOT USE 3 INCH EXHAUST DUCT
2. You can get the parts you need for installation
from your Whirlpool parts distributor or your local
plumbing and heating store.
3. We strongly recommend exhausting the dryer to
the outside to prevent large amounts of moisture
and lint from being blown into the room.
4. If you cannot exhaust your dryer to the outside,
use Exhaust Deflector Kit LCK4000 available from
your Whirlpool Dealer.
5. Exhaust outlet at rear of the dryer is located as
shown in Figure 16. Detailed instructions on spacing
for side and rear clearances can be found in the sec-
tion "Instructions for Recessed or Closet Instal-
lations." Information on minimum spacing side to
side and to the rear is also found on a label located
on back panel.

6. We strongly recommend exhausting with 4 inch
diameter rigid METAL duct. We strongly recom-
mend METAL flexible duct if you use flexible duct.
Flexible aluminum duct is available from your
Whirlpool dealer or parts distributor. NEVER
USE SMALLER THAN 4 INCH EXHAUST DUCT.
7. The exhaust may be routed up, down, left,
right or straight through the wall.
8. The exhaust duct should terminate with an ex-
haust hood to prevent back drafts. The outlet of
the hood must be at least 12 inches from the
ground or any obstruction. A louvered exhaust
hood, Part Number 279399 is available from your
Whirlpool dealer or parts distributor. An exhaust
hood with a 2% inch outlet creates more back pres-
sure, but may be used with shorter systems. Never
use an exhaust hood with a magnetic latch.
9. The maximum length of the exhaust system de-
pends upon the type of duct used, the number of
elbows and the type of exhausted hood. The max-
imum length for both rigid and flexible duct is
shown in the chart, FIG. 17.

10. Use duct tape to seal all joints. Never use
screws to assemble the ductwork, screws can catch
lint.
11. Exhaust systems longer than specified will short-
en the life of the dryer and result in reduction of
performance such as longer drying time and in-
creased use of energy. Lint may also accumulate
creating a possible safety hazard. The exhaust sys-
tem should be cleaned periodically, at least every
two years.
12. We do NOT RECOMMEND non-metallic flex-
ible duct. If you use non-metallic flexible duct you
must connect a METAL elbow and at least 2 feet
of METAL duct to the dryer outlet. The length of
the non-metallic flexible duct should not exceed 7
feet, and it must be adequately supported to pre-
vent sagging or kinking. See FIG. 18.

DUCT CONCEALED IN WALLS OR CEILING

For your personal safety, a metal elbow and at least 2 feet of
metal duct must be used at the outlet of the dryer. This
reduces the possibility of lint blocking the exhaust,system
and minimizes the potential of a fire hazard. The 2 feet of
metal duct also helps make any service that may be needed
easier and prevents crushing the flexible duct when the dryer
is moved to its final operating location.
