Chapter 3: Installation

3-1 Work Rules

The installation, operation, and maintenance of this equipment must be conducted in accordance with all applicable work and safety codes for the installation location. This may include, but not limited to, OSHA, NEC, CSA, and any other local, national and international regulations.

1.Read and follow these operating instructions when installing, operating and maintaining this equipment. If the instructions become damaged or unreadable, additional copies are available from the manufacturer.

2.Only qualified personnel familiar with this equipment should work on or with this dryer.

3.Work with approved tools and devices.

4.Disconnect the electricity before maintenance or service. If the dryer is installed with a power cord that can be unplugged, unplug it. If the dryer is permanently wired to a power main, a fused power disconnect must be installed to allow the disconnect to be locked in the "OFF" position. Open and lock out the disconnect installed in the control enclosure.

3-2 Electrical Connections

The voltage, phase and amp draw information is listed on the serial tag.

;Line voltage must be within ±10% of the voltage listed on the serial tag, or damage may occur. Phase imbalance must be less than 5%.

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

;Connection should be made by a qualified electrician.

;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.

3-3 Check For Proper Blower Rotation

The blowers are rotating properly when air flows from the delivery outlet.

•Incorrect phasing of power leads will cause backward rotation of blower motors and contamination of the desiccant.

If both blowers are rotating improperly, reverse any two wires at the fused disconnect outside the dryer or at the disconnect/terminal in the control enclosure. This assures that both blowers will be rotating in the proper direction.

•Reverse the wires at the motor starters only if one blower is rotating incorrectly.

3-4 Dryer/Drying Hopper Process Air Hose Connection

;Use high-temperature flexible dryer hose or rigid tubing to connect the dryer to the drying hopper.
