A qualified technician should
change the exhaust air outlet to the
optional connection location.
Ductwork
To ensure optimum performance,
the ducting system of the dryer
should be as short as possible with
a minimum number of elbows.
Your dryer will work best when the
venting system has as few air flow
restrictions as possible. Exhaust
ducting which is longer than
recommended may extend drying
time, cause tint to accumulate and
affect dryer performance and dryer
life.
Four inch (approx. 100 mm)
diameter ducting should be used.
Use either rigid metal or flexible
metal ducting material. DO NOT
use plastic or non metal duct with
this dryer.
/
All joints should be tight to avoid
leaks. The mate end of each duct
section must point away from the
dryer.
Whether connecting to an existing
venting system or a new venting
system, make sure that atI ducting
is clean and free of tint.
The maximum permitted length for
both rigid and flexible metal duct is
shown in the table betow.

the chart.
