B. Air compressor intake–Locate air compressor so that contaminants potentially harmful to the dryer (e.g. ammonia) are not drawn into the air system.

C. Clearances

Free air flow - Allow at least 12 inches (305 mm) on the front and each side of the cabinet and 6 inches

(152 mm) at the back of the cabinet for free air flow.

Service - To facilitate maintenance leave 24 inches

(610 mm) of clearance in front of dryer.

D. Standard units are designed to operate in ambients from 45 to 110 ° F (7 to 43 ° C).

E. Installations in altitudes above 4500 feet (1370 meters)

– Dryer is adjusted to operate in altitudes up to 4500 feet (1370 meters). If dryer is installed in an altitude above this, and has not been preset at the factory for this altitude, contact manufacturer’s Service Department.

1. Connect cooling water supply to cooling water inlet.

2. Connect cooling water return line to cooling water outlet connection.

1.5 Moisture separator

A. Separator has an internal drain which automatically discharges collected condensate. It may be desirable to pipe the condensate from the Automatic Drain outlet to a suitable drain.

NOTE:

Discharge is at system pressure. Drain line should be anchored.

NOTE:

Condensate may contain oil. Comply with applicable laws concerning proper disposal.

B. Separator has a knurled fitting with flexible drain tubing attached. Be sure knurled fitting is tightened by turning it counter-clockwise before operating dryer.

Sizing

Determining dryer capacity at actual operating conditions

To determine the maximum inlet flow capacity of a dryer at various operating conditions, multiply the rated capacity from Table 1 by the multipliers shown in Table 2.

Example: How many scfm can an air-cooled model 125 handle when compressed air to be dried is at 80 psig and

90

°

F; ambient air temperature is 80

°

F; and a 35

°

F dew point temperature is desired?

Answer: 125 x 1.17 x 1.12 x 1.0 = 163.8 scfm.

TROUBLESHOOTING GUIDE

SYMPTOM

A.

Water downstream of dryer

B.

High pressure drop across dryer

POSSIBLE CAUSE(S)

1. Residual free moisture remaining in downstream pipelines

2. Air by-pass system is open

3. Inlet and Outlet connections are reversed

4. Temperatures surrounding air lines downstream of dryer have dropped below dryers dew point rating

5. Excessive free moisture (bulk liquid) at dryer inlet

6. Condensate not being automatically drained

Drain mechanism is clogged or inoperative.

Drain line is restricted or frozen.

Electric drains–timer not set to allow for sufficient condensate removal

7. Dryer overloaded resulting in elevated dew point.

8. Refrigeration system not functioning properly resulting in elevated dew point.

1. Excessive air flow

2. Freezing of moisture in evaporator because of refrigeration system improperly functioning.

3. Separator filter element clogged.

CORRECTIVE ACTION

Warranty

The manufacturer warrants the product manufactured by it, when properly installed, operated, applied and maintained in accordance with procedures and recommendations outlined in the manufacturer’s instruction manuals, to be free of defects in material and workmanship for a period of one (1) year from date of purchase at the retail level by the end user, not to exceed eighteen (18) months from the date of manufacture, provided such defect is discovered and brought to the manufacturers attention within the aforesaid warranty period.

The manufacturer will repair or replace any product or part determined to be defective by the manufacturer within the warranty period, provided such defect occurred in normal service and not as the result of misapplication, misuse, abuse, neglect, incorrect maintenance, accident, or normal wear. Normal maintenance items requiring routine replacement are not warranted.

The warranty covers parts and labour for the warranty period. Repair or replacement shall be made at the sole option of the manufacturer. Any service performed on the product by anyone other than the manufacturer must first be authorized by the manufacturer. Unauthorized service voids the warranty and any resulting charge or subsequent claim will not be paid.

Products repaired or replaced under warranty shall be warranted for the unexpired portion of the warranty applying to the original product, based on the original date of purchase and/or date of manufacture, as outlined above.

There is no other expressed warranty. Implied warranties including those of merchantability and fitness for a particular purpose are limited to one (1) year from date of purchase to the extent permitted by law and any and all implied warranties are excluded. This is the exclusive remedy. Liability for consequential damages under any and all warranties are excluded to the extent exclusion is permitted by law.

This warranty gives you specific legal rights, and you may also have other rights within your jurisdiction.

This warranty does not cover:

1.

Merchandise that has become inoperative because of ordinary wear, misuse, negligence, accident, or improper and unauthorized repair or alteration.

2.

Costs occasioned by the removal, replacement, or repair of merchandise (other than by Devair) without previous written authorization.

3.

Expenses incurred in travel or lodging beyond a 40 kilometer (25 mile) distance from the nearest Devair

Authorized Service Centre, unless approved by Devair in advance.

4.

Products, parts, materials, components, or accessories manufactured by others or supplied in connection with the sale of the manufacturers products.

5.

Repair and transportation costs of merchandise determined not to be defective under the terms and conditions of this warranty.

All decisions by Devair Inc. with regard to this policy shall be final. Devair will not be responsible for any claimed defective materials returned other than in accordance with this statement of policy or without our prior authorization.
