INSTALLATION AND OPERATING INSTRUCTIONS
Note: Before installation, check that the local distribution conditions, nature of gas and pressure, and the
adjustment of the appliance are compatible.
Note: A forklift, or a hand pallet truck or jack, must lift the dryer and only from the front or rear of the dryer with
the washer bolted to the pallet and supported the full length of the dryer.
UNCRATING
Tools required: 3/4 in. (19 mm) hex socket and ratchet driver, knife, and groove-joint pliers that opens to 1 3/8
in. (35 mm).
1. Remove the plastic wrap with the knife. Remove the cardboard rails, the fillers and the top cap.
2. Using a ratchet driver and a 3/4 in. (19 mm) hex socket, remove the (4) bolts attaching the wooden skid to
the dryer cabinet. Save the bolts for future moving of the dryer.
3. With a walking motion, move the dryer forward completely off the wooden skid. Save the skid for future
moving of the dryer.
Note: If the dryer is ever moved again, the dryer should be re-mounted on its pallet and its crating bolts reinserted and tightened, in the reverse order as above.
DRYER ONLY INSTALLATION
1. Using the groove-joint pliers, install the leveling legs where the shipping bolts were removed when the
shipping bolts held the skid.
STACK WASHER / DRYER INSTALLATION
1. Place the dryer on the top of the washer and align with the (4) mounting holes. The front (2) mounting holes
are located inside the lint compartment 5½ in. (140 mm) from the front of the machine. The back (2)
mounting holes are located on the right/left side of the machine, at the base of the back panel. Removing the
rear guard is necessary to access the back mounting hole located opposite the duct work.
2. Use the (4) supplied 5/16 in. (8 mm) x 1-1/4 in. (32 mm) dog tip bolts to secure the dryer on the top of the
washer.
DRYER INSTALLATION
This appliance must be installed in accordance with the rules in force and used only in a sufficiently ventilated
space. Consult instructions before installation of this appliance.
1. CODE CONFORMITY. All commercial dryer installations must conform to local and the national codes for the
location of the installation and the venting requirements.
The appliance must not be installed behind a lockable door, a sliding door or a door with a hinge on the opposite
side to that of the tumble dryer, in such a way that a full opening of the tumble dryer door is restricted.
2. INSTALLATION CLEARANCES. This unit may be installed at the following alcove clearance. (millimeters)
I. Left Side 0 in.
II. Right Side 0 in. *
III. Back 18 in. (457) (Certified for 1 in. (25) clearance; however, 18 in. (457) clearance is
necessary behind the belt guard to allow servicing and maintenance.)
IV. Front 48 in. (1220) (to allow use of dryer)
V. Top Refer to figure on the next page labeled “Vertical Clearance Dimensions”. Certification
allows 0 in. clearance at the top 4 in. (100) back from the front. However, a 1/4 in. (6)
clearance should be allowed in case the dryer needs moving.
A 10 in. (254) clearance is required from the top at all other points.
VI. Floor This unit may be installed upon a combustible floor.
Do not obstruct the flow of combustion and ventilation air.
8514-272-002 Rev PR page 8
Maintain minimum of 1 in. (25mm) clearance between duct and combustible material.
Refer to installation label attached to the rear guard of the dryer for other installation information.
VERTICAL CLEARANCE DIMENSIONS
3. MAKE-UP AIR. Adequate make-up air must be supplied to replace air exhausted by dryers on all types of
installations. Refer to specifications for the minimum amount of make-up air opening to outside for each dryer. This is a
net requirement of effective area. Screens, grills or louvers, which will restrict the flow of air, must be considered.
Consult the supplier to determine the free area equivalent for the grill being used. The source of make-up air should be
located sufficiently away from the dryers to allow an even airflow to the air intakes of all dryers. Multiple openings
should be provided.
NOTE: The following considerations must be observed for gas dryer installations where dry cleaners are installed.
The sources of all make-up air and room ventilation air movement to all dryers must be located away from any
dry cleaners. This is necessary so that solvent vapors will not be drawn into the dryer inlet ducts. Dry cleaner
solvent vapors will decompose in contact with open flame such as the gas flame present in clothes dryers. The
decomposition products are highly corrosive and will cause damage to the dryer(s) ducts and clothes loads.
The operation of this appliance may affect the operation of other types of gas appliances, which take their air for
safe combustion from the same room. Adequate ventilation must be provided to avoid back flow of gasses from
other appliances in the same room. All other gas appliances should be tested with the Dexter dryer in operation
and all the windows and doors closed. If in doubt, consult the appliance manufacturer(s).
4. ELECTRICAL REQUIREMENTS.
The electrical installation must be performed by a qualified electrical technician.
The electrical power requirements necessary to operate the unit satisfactorily are listed on the serial plate located on
the back panel of each dryer and in the specifications section of this manual. The electrical connection should be
made to the terminal board, on the rear of the unit using copper conductors of 15A minimum capacity. A 22 mm
8514-272-002 Rev PR page 9
(7/8 in.) hole is provided for the connection of conduit for the power supply conductors. It is absolutely necessary
that the dryer be connected to a known earth. Individual circuit breakers for each dryer are required.
Introduction of supply wiring must not increase the Ingress Protection (IP) rating.
The installation must meet the National Electrical Requirements of the country, state, or locality of installation.
The installer must provide a disconnect switch which will interrupt both lines. It may be a local or national
requirement to provide an electrical interruption switch visible and accessible from the room in which the dryer is
installed. The wiring diagram is located on the belt guard on the back of the machine.
For destination countries where CE requirements must be met, individual 230V supply disconnecting devices for
each dryer are required and must be one of the following types:
a. switch-disconnector with fuses per IEC 60947-3 utilization category AC-23B;
b. disconnector with fuses per IEC 60947-3 having an auxiliary contact that in all cases causes switching devices
to break the load circuit before the opening of the main contacts of the disconnector;
c. a circuit-breaker suitable for isolation per IEC 60947-2;
d. any other switching device in accordance with an IEC product standard for that device and which meets the
isolation requirements of IEC 60947-1 as well as a utilization category defined in the product standard as
appropriate for on-load switching of motors or other inductive loads;
The supply disconnecting devices must
a. provide a means allowing the supply disconnecting devices to be locked in the OFF position;
b. be mounted 0.7 m to 1.7 m above the floor, within 2 m from the dryer, and within 8 m from the operator
position;
c. have a red actuator to indicate that it serves a dual Emergency Stop function;
d. be rated for branch circuit operation;
e. be approved for use in the country where installed;
CONTROL TRANSFORMER CONNECTIONS Adjustment for different voltages of supply mains.
IMPORTANT: TRANSIENT VOLTAGE SURGE SUPPRESSORS
Like most electrical equipment, your new machine can be damaged or have its life shortened by voltage surges
due to lightning strikes which are not covered by factory warranty. Local power distribution problems also can
be detrimental to the life of electrical components. We recommend the installation of transient voltage surge
suppressors for your new equipment. These devices may be placed at the power supply panel for the complete
installation and don’t require an individual device for each machine.
These surge protectors help to protect equipment from large spikes and also from small ongoing spikes in the
power that occur on a day to day basis. These smaller surges can shorten overall life of electrical components of
all types and cause their failure at a later date. Although they can’t protect against all events, these protective
devices have a good reputation for significantly lengthening the useful life of electronic components. Electronic
8514-272-002 Rev PR page 10
components are helped to have a longer useful life when they are supplied with the clean stable electrical power
they like.
