1. Pre-Installation
1.1 Inspection, Handling and Setup
Inspect the dryer carefully upon arrival and note any damage on the freight bill. File a notice of
concealed damage if: (1) there are any dents in the cabinet; (2) the air and drain pipes are not
straight; (3) there is any sign of oil on the skid oor. File these claims with the carrier immediately!
Cautions and Operating Warnings:
• Never work on unit under pressure
• Never work on unit when power is connected.
• Do not over-pressurize unit.
• Install unit in a clean, cool (50º - 95ºF / 10º - 35ºC); well lighted location
• Do not shut unit off at disconnect switch except during service. Unit must be
turned on and off by the panel switch located on the dryer.
• Do not operate dryer at abnormal conditions (high ow, high inlet temperature,
high ambient, high inlet pressure, etc.)
2. Dryer Installation
2.1 Location of Dryer
Unless supplied for special conditions, the air-cooled dryers must be located in an area with an
ambient temperature between 10ºC (50ºF) and 38ºC (100ºF), and free from explosive and corrosive
fumes. High ambient temperatures affect the outlet dew point of the dryer. For every 4ºC (39ºF)
of ambient temperature over 38ºC (100ºF), a decrease of 6% of dryer performance is encountered
with air-cooled dryers. The unit must not operate in an ambient of over 38ºC (100ºF). For ambient
conditions of over 38ºC (100ºF), water cooled dryers are suggested and are available upon
request.
2.2 Outdoor Installation (Sheltered)
There are certain items that should be incorporated into the system to help ensure trouble-free
operation.
The dryer should be on a concrete pad, which is designed to drain water away from it. If the
concrete pad is sloped, then the dryer must be mounted so that it is level. The base of the skid
must be sealed where it contacts the concrete pad.
If local weather conditions can be extreme such that direct rain or snow may fall on the unit, it
should be in a full enclosed room or building. The dryer must be protected from the elements.
If installed under a shelter, air-cooled machines must be positioned in a way that prevents air
recirculation.
If installation include more than one component, hot air exhaust should not be directed toward the
fresh air intake of the dryer.
A standard machine installed outside must not be started or run if the ambient temperature in and
around the dryer drops or may drop below 50ºF (10ºC).
CAUTION – Three feet of space must be allowed between all open grills and walls or other
objects. If the dryer is installed in a conned area, an exhaust system must be provided to avoid
excessive recirculation of hot room air.

MSC4000 - MSC15000 USER GUIDE
2.3 Airline Plumbing
All connections are made to the outside of the cabinet as follows:
• Plumbing must be supported independently of the dryer.
• If vibration is present, exible metal hoses must be installed to prevent it from being
transmitted to the dryer.
• Use unions or ange joints.
• Bypass piping around the dryer is recommended for ease in servicing or removal of unit if
necessary.
• Direction of ow through the dryer must be observed. A check valve on the outlet of the
dryer to prevent back ow and false loading is recommended.
NOTE: Use two wrenches when connecting to dryer piping so as to prevent damage to internal
air or water lines.
On water-cooled units, install a strainer. Minimum water pressure is 30 psi (2.1 bar g). Maximum
water inlet pressure is 150 psi g (10.4 bar g). Dryers are designed for inlet water temperature.
Higher water temperature reduces dryer capacity (consult the factory for water temperatures
above 85ºF (29ºC).
2.4 Electrical Connections
Before connecting electrical power to the dryer if applicable
• Check for correct voltage and phase at electrical connection box.
• Install a fused disconnect switch near the dryer.
• Connect power to the stripped leads located in the electrical connection box or to main
lugs of contactor, whichever is necessary.
• (NOTE: All units must be externally grounded to protect against the possibility of
severe electrical shock)
• CAUTION: Wire the dryer separately from the air compressor. The dryer must NOT cycle
on and off with the air compressor.
• Phase rotation is only important if the dryer has a 3-phase condenser fan. Fans must
PULL air through the condenser coil.
• Crankcase heaters are pre-wired at the factory to the line side of the terminal box or
contactor. Heaters must be energized at all times, therefore the main disconnect must be
left on except when servicing the dryer.

3. Principle of Operation
The dryer is designed to operate automatically and continuously from no load to full load without freeze up.
Air System
The major air system components are the air-to-air PRECOOLER / REHEATER, the EVAPORATOR, and the
MECHANICAL SEPARATOR.
Hot, wet air enters the inlet of the precooler/reheater where it is cooled by the outgoing air. The air then
enters the evaporator where it is cooled by the refrigerant causing the air’s humidity to condense into liquid
water.
Next, the air travels to the separator. The air enters the separator where bulk oil and moisture are removed
from the air stream through a combination of centrifugal action and velocity reduction. After removal from
the air stream, all contaminants are ejected from the air system by automatic solenoid or oat drains.
From the separator, the cold dry air enters the outgoing side of the precooler/reheater where it is reheated
by the hot incoming air.
The precooler/reheater serves a triple purpose. By precooling the incoming air, it conserves refrigeration
use and by reheating the outgoing air, it serves to eliminate sweating of pipes in the plant air system. Most
important, it increases the temperature dew point split, preventing moisture from condensing out of the
compressed air when the air is expanded.

4. Start Up Procedure
4.1 Preliminary Checks
Before starting the dryer, verify that the compressed air valves are closed so there is no airow
through the dryer, the dryer supply voltage is correct, and there is sufcient water supply to the
unit (water cooled). Also ensure unit is level at this time.
4.2 Refrigeration Service Valves
Open all valves marked with a “VALVE CLOSED” label.
Note: Always use a refrigeration service valve wrench on the spindles.
Remove the black plastic cap and completely backseat the valve spindle (counter clockwise) on
service valves and turn all 90 deg valves to the open position.
Note: Before replacing the caps, tighten the packing on all service valves.
4.3 Starting the Dryer
• Open the electrical panels and verify all electrical connections prior to powering up the dryer.
• Check and verify the service switch is in the “OFF” position.
• Close panels and supply power to the dryer.
• After power has been applied the control panel should say “OFF” and the crankcase heater
will now start heating.
• THE CRANKCASE HEATER MUST BE SWITCHED ON 12 HOURS BEFORE STARTING THE
DRYER. Failure to comply with this rule may cause serious damage to the compressor.
• Open the condenser water supply and return valves on water-cooled units.
• If necessary, bleed the air from the condenser water shell.
START THE DRYER BEFORE SUPPLYING AIR!
• Turn the service switch to the “ON” position. The refrigeration compressor may run
momentarily.
• Depress the “LOAD / UNLOAD” button to start the dryer.
• Verify correct rotation of fans on air-cooled units. There is no rotation that needs to be
checked on water-cooled units.
• Wait until the dryer reaches cycling temperatures and pressures.
Note: If the dryer overshoots the “OFF” temperature 30-32ºF (-1-0ºC) and you experience an
“E-1” alarm, SLOWLY pressurize the dryer by opening the compressed air inlet valve and verify
the cable connection as outlined in the operation and troubleshooting manual. Due to the thermal
bank effect of the ooded evaporator, it is normal for the dew point temperature to fall below the
“OFF” temperature after the refrigeration compressor shuts down with little or no load. The alarm
should clear once the dew point probe temperature rises into its operating range.
Verify the liquid level in the expansion tank sight glass for proper oil return! Adjustment is
usually not required, and the refrigerant level must be veried after 24 to 48 hours of operation.
Adjust as necessary, using the level control valve (TXV). Counterclockwise raises the level &
clockwise lowers the level. The oil level in the refrigeration compressor should be between ¼
and ¾ in the compressor sight glass. Contact Customer Service if there are ANY questions. The
refrigerant level will rise and fall during normal operation.
CAUTION: If liquid level is not operating within this site glass, there will be insufcient oil return
and refrigerant compressor damage will result. If there is excessive liquid (overll) in the expansion
tank, there will be liquid ood-back and refrigerant compressor damage will result.
• SLOWLY open the air inlet valve gradually to pressurize the dryer if this has not already been
done.
• SLOWLY open the air outlet valve.

8
MSC4000 - MSC15000 USER GUIDE
• SLOWLY close the air bypass valve until the dryer is under an air load.
Note: Fast opening of air valves could damage the heat exchangers. At this time, complete the
following start up form.
Note: The refrigerant compressor may require additional oil added. Oil level will need to be veried
at the same time as the expansion tank refrigerant level (within 24 to 48 hours) to ensure correct
system operation and adjustment.
For units supplied with Refrigeration Oil Separator (STD on Water cooled units – MSC12000
& UP and STD on Air cooled MSC10000 & UP)
• Change oil separator element 24-48 hours after initial start-up.
• An extra element for this change out is supplied with shipment.
