Fresh Air Supply Requirements _______
This appliance may only be installed in a room that meets the
appropriate ventilation requirements specified in the national
installation regulations.
When the dryer is operating, it draws in room air, heats it,
passes this air through the tumbler, and exhausts it out of the
building. Therefore, the room air must be continually
replenished from the outdoors. If the make-up air is
inadequate, drying time and drying efficiency will be adversely
affected. Ignition problems and sail switch “fluttering” problems
may result, as well as premature motor failure from
overheating. The dryer must be installed with provisions for
adequate combustion and make-up air supply.
Air supply (make-up air) must be given careful consideration
to ensure proper performance of each dryer. As a general
rule, an unrestricted air entrance from the outdoors of 70 inch
2
(451 cm
2
) for each SD35, 125 inch
2
(806 cm
2
) for each SD50,
and 135 inch
2
(870 cm
2
) is required for each SD80. (Based
on 1-inch
2
[6.5 cm
2
] per 1,000 Btu [252 kcal].)
It is not necessary to have a separate make-up air opening
for each dryer. Common make-up air openings are acceptable.
However, they must be set up in such a manner that the make-
up air is distributed equally to all the dryers.
To compensate for the use of registers or louvers used over
the openings, this area must be increased by approximately
33%. Make-up air openings should not be located in an area
directly near where exhaust vents exit the building.
Allowances must be made for remote or constricting
passageways or where dryers are located at high altitudes or
predominantly low pressure areas.
NOTE:
Component failure due to dry cleaning solvent
fumes will void the warranty.
EXAMPLE: For a bank of four SD35 dryers, two unrestricted
openings measuring 12-inches by 12-inches (30.5 cm by 30.5
cm) are acceptable.
IMPORTANT:
Make-up air must be free of dry cleaning
solvent fumes. Make-up air that is contaminated by dry
cleaning solvent fumes will result in irreparable damage to
the motors and other dryer components.
A = 12-inches (30.5 cm)
B = 12-inches (30.5 cm)
A The requirement to allow the lint door to open completely for the
SD35 is 33-inches (83.8 cm), SD50 is 36” (91.4 cm), SD80 is
40-inches (101.6 cm).
B A minimum overhead clearance of 12-inches (30.48 cm) is required.
18-inches (45.72 cm) is recommended.
C Dryer should be positioned a minimum of 12-inches (30.48 cm)
away from the nearest obstruction. 24-inches (60.96 cm) is
recommended for ease of installation, maintenance, and service.
D 1/16” (1.5875 mm) minimum is required.
E Flooring in front of the dryer must be lower than the dryer cabinet to
allow the lint door to open.
F Dryers may be positioned sidewall to sidewall, however a 1/16”
(1.5875 mm) minimum allowance must be made for the opening
and closing of the lint door, along with the removal of panels during
maintenance.
G Dryer must protrude 1-inch (2.54 cm) from the surface of any
bulkhead or partition around the dryer to allow the control door to
open.
H The maximum thickness of any bulkhead or partition from the header
down to the top of the dryer is 1-inch (2.54 cm).
I
The minimum clearance from the top of the dryer to the header of
any bulkhead or partition located directly above the dryer is
4-inches (10.16 cm).
J The maximum thickness of any bulkhead or partition above the
header is 4-inches (10.16 cm).
13. Reinstall the bottom main door hinge block. This was
the top hinge block and now has the plastic washer on it.
14. Reinstall the main loading door, and the top hinge block.
The top hinge block was the bottom hinge block, with no
plastic washer.
15. Check that the doors swing properly.
16. Close all doors and panels. Then reconnect the power to
the dryer.
17. Check that the dryer starts with no errors.
18. Check that the dryer stops when either door is opened.
NOTE:
Some doors have a custom logo bar inside. While
the door is off the dryer, the door pan can be removed (6)
1/4 nuts, to access the logo bar. The bar can then be
removed and flipped. Reinstall the door pan.
Dryer Enclosure Requirements _______
Commercial Type II (SD35, SD50, SD80)
Bulkheads and partitions should be made of noncombustible
material.
NOTE:
Allowances must be made for opening the control door.
