2. INSTALLATION

Arrow Regenerative Air Dryers are shipped as completely assembly packages, filled with

desiccant ready to install.

Visually check the dryer to make certain that all air lines and electrical connections are

securely fastened and were not damaged in transit. If there is evidence of damage,

immediately enter a claim with the carrier, and notify your Arrow representative.

A. APPLICATION CHECK AND ANALYSIS

To achieve the best dryer performance, you should carefully check that the design and

installation requirements outlined below are satisfied.

1. Operating pressure of your Arrow Dryer can range from 75 min to 150 max PSIG. Check

dryer label and ASME nameplate to verify maximum service pressure. Air available for

your air usage will vary with operating pressure.

2. The dryer should not be installed where compressed air and/or ambient temperature

exceeds 120°F or drops below +32°F. Locate dryer to avoid extremes of heat and cold

from other conditions. Best results occur when dryer is located as close to point of use

as practical. Where applicable, dryer towers should be insulated to reduce heat loss.

Avoid locating dryer outside or where it is exposed to the elements.

3. Dryers are sized according to airflow not pipe size. Dryer requires 10% to 15% of inlet

air (SCFM) for regeneration. The difference between the inlet and outlet flow is the

amount of purge air required. This air is purged to atmosphere and is not available for

use downstream. Make certain air supply to dryer meets your air demand plus purge air

requirements.

NOTE

DRYERS MUST BE SIZED FOR USABLE AIR REQUIRED PLUS PURGE AIR

WHICH EQUALS REQUIRED INLET AIR FLOW TO DRYER.

B. MOUNTING SPECIFICATIONS AND DRYER LOCATION

1. Electrical connection must be hard piped with an external fused disconnect switch with

proper overload protection.

2. Frame must be suitably ground.

WARNING

ARROW DRYERS ARE WIRED FOR HIGH VOLTAGE. ONLY QUALIFIED

ELECTRICIANS ARE AUTHORIZED TO SERVICE THIS ELECTRICAL

EQUIPMENT.
