GENERAL SAFETY INFORMATION
1.
Pressurized devices
This equipment is a pressure containing device.
• Do not exceed maximum operating pressure as
shown on equipment serial number tag.
• Make certain equipment is depressurized before
servicing.
2.
Electrical
This equipment requires electricity to operate.
• Install equipment in compliance with national and
local electrical codes.
• Standard equipment is supplied with NEMA 1 electrical enclosures and is not intended for installation
in hazardous environments.
• Disconnect power supply to equipment when performing any electrical service work.
3.
Breathing air
• Air treated by this equipment may not be suitable
for breathing without further purification. Refer to
OSHA standard 1910.134 for the requirements for
breathing quality air.

1.0 INSTALLATION
1.1 Location
2. Location in the compressed air system
A. Air compressor intake - Locate air compressor so that
contaminants potentially harmful to the dryer are not
drawn into the air system.
A.
B. Free air flow - Do not block either side of the cabinet. Observe minimum installation clearances as shown.
1) For maximum capacity, install unit in air system
at highest pressure possible (e.g. before pressure
reducing valves)
36"
wall
6"
Maximum working pressure - 250 psig,
17.6 kgf/cm2. Do not exceed unit’s Maximum Working
Pressure.
2) For maximum capacity, install unit at coolest compressed air temperature possible. Maximum inlet
compressed air temperature: 180°F, 82°C. If inlet
air exceeds this temperature, precool the air by
extending the piping between the compressor and
the dryer.
12"
B. Air Outlet - Connect air outlet to downstream air lines.
24"
C. By-pass piping - If servicing the unit without interrupting the air supply is desired, piping should include inlet
and outlet isolation valves and an air by-pass valve.
1.2 Mounting
Dryer is suitable for floor or shelf mounting.
D. Condensate drain - It is advisable to connect drain
outlet to the condensate drainage system.
1.3 Piping connections
A. Air Inlet - Connect compressed
air line from air compressor to
air inlet using strainer supplied.
1. Install strainer (included in
shipping carton) prior to
dryer inlet using pipe nipple
supplied or other piping as
required.
NOTE: Drain discharge is at system pressure. Drain line
should be anchored to prevent whipping.
1.4 Electrical connections
A. Dryer is designed to operate on power supply (voltage)
listed on serial number tag located on the back of the
dryer.
B. Dryer is supplied with an electrical cord. Install in receptacle of proper voltage. NOTE: Observe flow direction arrows on strainer.
NOTE: Install strainer where it is easily accessible for cleaning.
NOTE: Use vibration dampener, if vibration exists in air line
at inlet to dryer.
NOTE: Models 50 and 75 (115v only) - Install plug
in receptacle rated for 20 amps. Units are supplied with 20 amp plug.
Plug
NOTE: Refrigeration system is designed to run continuously and should NOT be wired to cycle on/off with the air
compressor.

or not securely mounted.
CORRECTIVE ACTION
Blow out system with dry air
Check valve positions
Check for correct connection
Insulate or heat trace air lines exposed
to low ambients or dry air to lower
dew point
Install separator ahead of dryer
Replace drain mechanism if inoperative
Open drain line
Check inlet air temperature and pressure, flow rate (compressor capacity)
and ambient air temperature
See D below
Clean inlet air strainer
Check flow rate
Replace filter sleeve
See D below
See A 7
See D below
Contact qualified refrigeration repairman or manufacturer’s service department
D) Refrigeration system not functioning properly
1. When dryer on/off switch in on or
"I" position
a.
b.
c.
d.
Power failure
Line disconnect switch open
Blown fuses, open breaker
Faulty wiring, loose terminals
2. Refrigerant compressor cycles on
and off
a. High or low ambient conditions
b. Ambient air filter clogged
c. Condenser fins clogged
d. Fan motor or fan control switch
malfunction
e. Refrigerant leak
f. Low voltage
Check power to unit
Close disconnect switch
Check for continuity
Have electrician check electrical connections
Check minimum/maximum temperature ranges
Clean ambient air filter
Clean condenser
Replace fan motor or fan control
switch

WARRANTY
The manufacturer warrants the product manufactured by it, when properly installed, operated, applied, and
maintained in accordance with procedures and recommendations outlined in manufacturer’s instruction manuals, to be free from defects in material or workmanship for a period as specified below, provided such defect is
discovered and brought to the manufacturer’s 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 a result of misuse, abuse,
neglect or accident. Normal maintenance items requiring routine replacement are not warranted. The warranty
covers parts and labor for the warranty period unless otherwise specified. Repair or replacement shall be made at
the factory or the installation site, 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.
The foregoing is the exclusive remedy of any buyer of the manufacturer’s product. The maximum damages liability of the manufacturer is the original purchase price of the product or part.
THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES, WHETHER WRITTEN, ORAL, OR
STATUTORY, AND IS EXPRESSLY IN LIEU OF THE IMPLIED WARRANTY OF MERCHANTABILITY AND THE IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE. THE MANUFACTURER SHALL NOT BE LIABLE FOR LOSS OR DAMAGE BY
REASON OF STRICT LIABILITY IN TORT OR ITS NEGLIGENCE IN WHATEVER MANNER INCLUDING DESIGN, MANUFACTURE
OR INSPECTION OF THE EQUIPMENT OR ITS FAILURE TO DISCOVER, REPORT, REPAIR, OR MODIFY LATENT DEFECTS
INHERENT THEREIN.
THE MANUFACTURER, HIS REPRESENTATIVE OR DISTRIBUTOR SHALL NOT BE LIABLE FOR LOSS OF USE OF THE PRODUCT OR OTHER INCIDENTAL OR CONSEQUENTIAL COSTS, EXPENSES, OR DAMAGES INCURRED BY THE BUYER, WHETHER ARISING FROM BREACH OF WARRANTY , NEGLIGENCE OR STRICT LIABILITY IN TORT.
The manufacturer does not warrant any product, part, material, component, or accessory manufactured by others and sold or supplied in connection with the sale of manufacturer’s products.
Warranty Period
Parts and labor for two (2) years from the date of shipment from the factory; heat exchangers are covered (parts
only) for an additional three (3) years (total of five [5]). On units that manufacturer requests be returned to the
factory, a one time removal/reinstallation labor allowance as noted in the Service Warranty Policies and Procedures Handbook will apply. Freight to the factory from the installation site and to the installation site from the
factory will be paid by the manufacturer; means of transportation to be specified by manufacturer.
AUTHORIZATION FROM THE SERVICE DEPARTMENT IS NECESSARY BEFORE MATERIAL IS
RETURNED TO THE FACTORY OR IN-WARRANTY REPAIRS ARE MADE.
