Never wire directly, or connect any additional wires, to the compressor
junction box. This will cause severe system malfunction.
CAUTION
7.5 INITIAL START-UP
• Turn customer fused disconnect to the “ON” position. The dryer “SYSTEM
ENERGIZED
”
light will illuminate.
• After the 3 minute safety delay, depress the dryer “ON/OFF” button.
• The “DRYER ON” light will illuminate.
• Provided the chiller temperature is above the Chiller Temperature Set Point, the
“REFRIG ON” light will illuminate and refrigeration system will operate.
• The “HIGH TEMP ALARM” light will illuminate upon start-up and remain that way
until the thermal mass fluid in the chiller reaches 50°F. After the temperature is
reduced below 50°F, the “HIGH TEMP ALARM” light will go out.
• After the refrigeration system shuts off, air flow may be introduced to the dryer.
• Drain settings should be checked as described in Section 6.3.
For water cooled models, the water valve must be manually opened to
ensure that the condenser is full of water prior to start-up.
N O T I C E
Exchanger temperature should never be set lower than 35° as system
malfunction could occur.
N O T I C E
Slowly pressurize dryer after start-up
CAUTION
After installation or a prolonged shutdown, start the dryer with no air load (no air
flow). This enables the dryer to reach its proper operating temperature in the
shortest time possible (typically within 30 minutes).
