American Dryer Corp ML-122D installation manual Compressed AIR, Preparation for OPERATION/START-UP

I. COMPRESSED AIR

The ML-122 is manufactured with a pneumatic Air Jet damper system, which requires an external supply of compressed air. The air connection is made at the rear of the top console.

1. Air Requirements

COMPRESSED	AIR PRESSURE
AIR SUPPLY
Normal	80 PSI	5.51 bars
Minimum Supply	70 PSI	4.82 bars
Maximum Supply	90 PSI	6.21 bars

Shaded areas are stated in metric equivalents

2.Air Connection

Air connection to system --- 1/8” F.P.T.

3.No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 PSI (5.51 bars) must be provided. It is suggested that a regulator/filter gauge arrangement be added to the compressed air line just before the dryer connection. This is necessary to insure that correct and clean air pressure is achieved.

J.PREPARATION FOR OPERATION/START-UP

The following items should be checked before attempting to operate the dryer:

1.Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.

2.Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label that is affixed to the left side panel area behind the top control (access) door (refer to the illustration on page 9). In the case of 208 VAC or 240 VAC, THE SUPPLY VOLTAGE MUST MATCH THE ELECTRIC SERVICE EXACTLY.

3.GAS MODELS - check to assure that the dryer is connected to the type of heat/gas indicated on the dryer data label.

4.GAS MODELS - the sail switch damper assembly was installed and pre-adjusted at the factory prior to shipping. However, each sail switch adjustment must be checked to assure that this important safety control is functioning.

5.GAS MODELS - be sure that ALL gas shutoff valves are in the open position.

6.Be sure that ALL electric box covers have been replaced.

7.Check ALL service doors to assure that they are closed and secured in place.
