should be made at the terminal blocks in the two control boxes on the rear of the unit using
conductors rated at 75 C (167 F) and a wire size adequate to handle the amperage and voltage
listed on the serial plate (see table on the next page for recommended minimum sizes). It is
absolutely necessary that the dryer be grounded to a known (earth) ground (No. 8 AWG copper
conductor recommended). Knockouts are provided for the connection of 1-inch conduit for the
power supply conductors and 3/8-inch conduit for the external grounding conductor.

For 240V power supplies, an earthed mid-point of a phase is required. The “high” leg of the 3-
phase electrical supply (delta) must be connected to terminal L3. A neutral is required for all
electrical supply variations; see the wiring diagram in the control box on the back of the dryer.
The installation must meet the electrical requirements of the country, state and locality of the
installation. The installer may be required to provide a disconnect switch which will interrupt
all 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 in the control box on the back of the dryer.
MISE À LA TERRE
Cet appareil doit être relié à une canalisation électrifique métallique fixe ou la dérivation doit
comporter un conducteur de terre connecté à la bome ou au fil de terre de l’appareil.
6. EXHAUST INSTALLATION. (Refer to Figure 3) Exhausting of the dryer(s) should be
planned and constructed so that no air restrictions occur. Any restriction due to pipe size or type
of installation can cause slow drying time, excessive heat, and lint in the room.
From an operational standpoint, incorrect or inadequate exhausting can cause a cycling of the
high limit thermostat, which shuts off the heating elements and results in inefficient drying.
The oval exhaust duct connection near the top of the dryer will accept a compressed 8” round
duct. Individual exhausting of the dryers is recommended. A pipe of the proper diameter should
be attached to the dryer adapter collar and extended out through an outside wall to exhaust all
heat, moisture, and lint outside. This pipe must be very smooth on the inside, as rough surfaces
