NOTE:
Refrigeration condensing unit is designed to run continuously and should NOT be wired to cycle on/off with the air
compressor.
NOTE:
Models 150 (115V only)—install plug in receptacle rated
for 20 amps.
WARNING: Refer to Serial Number Tag for maximum
working pressure. Do not exceed dryer’s Maximum
Working Pressure.
NOTE:
Install dryer in air system at highest pressure possible
(e.g. before pressure reducing valves).
NOTE:
Install dryer at coolest compressed air temperature
possible. Maximum inlet compressed air temperature:
120°F (49°C). If inlet air exceeds this temperature, precool
the air with an aftercooler.
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.
B. Air Outlet—Connect air outlet to downstream
air lines.
C. By-pass piping—
If servicing the dryer without interrupting the
air supply is desired, piping should include
inlet and outlet valves and an air by-pass valve.
D. Water cooled models—cooling water inlet and
outlet
1. Connect cooling water supply to cooling water
inlet.
2. Connect cooling water return line to cooling
water outlet connection.
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.
NOTE:

3.0 Maintenance
Sizing
3.1 Condenser coil—
Clean off accumulated dust and dirt monthly.
Determining dryer capacity at actual operating
conditions
3.2 Moisture separator—
Replace filter element when pressure drop across
dryer is excessive or annually.
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.
3.3 Check separator daily to be sure automatic drain is
discharging.
3.4 Replace drain mechanism annually.
To facilitate service, maintenance kits are available.

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.
