Notes: Hopper mounting flanges on 0.75 and and 1.5 cu. ft. (20 & 40 liter) hoppers are supplied blank so the customer

can drill to match existing machine throat.

3.0cu. ft. (80 liter) hoppers and larger are not supplied with a cast flange (as shown).

When using a hoist to move a machine mounted dryer, ALWAYS attach chains to the three (3) locations/lifting points on the unit! Moving the Dryer without the chains attached to all of the lifting points will cause the unit to become unstable and may cause damage to the Dryer and/or injury to personnel!

3-3 Electrical Connections

When making electrical connections to your dryer, ensure that you take into consideration and make arrangements for the following:

•A qualified electrician should make all electrical connections.

•Fulfill all national, state, and local safety and electrical code requirements.

•The serial tag lists voltage, phase, and amp draw information:

•Line voltage must be within plus or minus ten percent (±10%) of the voltage listed on the serial tag, or damage may occur. Phase imbalance must be less than two percent (2%).

•Connect main power to the dryer at the disconnect or terminals in the upper right corner of the control enclosure.

•Install a fused disconnect with a lockout feature in the power main leading to the dryer.

•The power drop must include a ground wire.

•Make sure all electrical connections are tight.
