INTRODUCTION

The dryers use mechanical refrigeration to dry compressed air. See Table 4 for rated

capacity and other dryer specifications.

To ensure continuous good performance and safe operation, everyone who installs, uses

or maintains the dryer must read and carefully follow the instructions in this manual.

SAFETY

The dryers are designed and built with safety as a prime consideration; industry-

accepted safety factors have been used in the design. Each dryer is checked at the factory

for safety and operation. All necessary adjustments are made before shipment.

Follow the maintenance schedules outlined in this manual for good performance and safe

operation. Maintenance should be done only by qualified personnel with proper tools.

Carefully read the following safety rules before proceeding with installation, operation or

maintenance. The rules are essential to ensure safe dryer operation. Failure to follow

these rules void the warranty or result in dryer damage or personal injury.

1. Do not install or try to repair a dryer that has been damaged in shipment.

See Receiving and Inspection for instructions.

2. Compressed air and electricity have the potential to cause personal injury or

equipment damage. Before doing any work in the dryer, be sure the electrical supply

has been locked and tagged and the internal pressure of the dryer has been vented to

the atmosphere.

3. Do not operate the dryer at pressures or temperatures above the maximum conditions

shown on the data plate.

4. Always supply electrical power that complies with the voltage shown on the data plate.

5. Do not readjust the dryer without factory authorization.

6. Work on the refrigeration system must be done only by a competent refrigeration

mechanic.

7. Use only manufacturer’s genuine replacement parts. The manufacturer bears no

responsibility for hazards caused by the use of unauthorized parts.
