INSTALLATION PROCEDURES
CAUTION: Improperly sized or installed exhaust duct work can create a potential fire hazard.
Where possible, it is desirable to provide a separate exhaust air duct for each dryer. The duct
should go as directly as possible to the outside air. Avoid sharp 90
o
ducting; use 30 or 45
the diameter of the duct. To protect the outside end of the duct from the weather, it may be bent
downward as indicated. Leave at least twice the diameter of the duct as clearance between the duct
opening and the nearest obstruction. If the exhaust duct goes through the roof, it may be protected
from the weather by using an 180
of the duct as clearance from the nearest obstruction. DO NOT use screens or caps on the outside
opening of the exhaust duct. The ducting should be smooth inside with no projections from sheet
metal screws or other obstructions which will collect lint. When adding, ducts, the duct to be added
should overlap the duct to which it is to be connected. Provide inspection doors for periodic clean –
out of lint from the main duct.
If it is not feasible to provide separate exhaust ducts for each dryer, ducts from the
individual dryers may be channeled into a common main duct. Each dryer is provided with a back
draft damper. The individual ducts should enter the bottom or side of the main duct at an angle not
o
more than 45 . The main duct should be tapered with the diameter increasing before each
individual duct is added.
Inadequate exhaust facilities may cause high temperature limit switches or airflow switches
to shut off the dryers. DO NOT disables the switches, which are provided for your safety. Instead,
investigate the exhaust ducting. Any obstruction or air friction due to numerous elbows / fittings in
the ducting will slow the passage of air through the system with resulting inefficiency and potential
fire hazard.
F. ELECTRICAL INFORMATION
1. Electrical Requirements
It is your responsibility to have all electrical connections made by a properly licensed and
competent electrician to assure that the electrical installation is adequate and conforms to local and
state regulations or codes. In the absence of such codes, all electrical connections, material, and
workmanship must conform to the applicable requirements of the National Electrical Code
ANSI/NFPA NO. 70 – LATEST EDITION.
IMPORTANT: Failure to comply with these codes or ordinances and / or the requirements
stipulated in this manual can result in personal injury or component failure.
NOTE: Component failure due to improper installation VOIDS THE WARRANTY. A separate
circuit serving each dryer must be provided. The dryer must be connected to copper wire
only. DO NOT use aluminum wire which could cause a fire hazard.
NOTE: The use of aluminum wire VOIDS THE WARRANTY.
