Section 2.0 - Getting Started
Before unpacking/uncrating your new dryer, inspect the carton/crate for damage. Note any damage on the
freight bill. File notice of concealed damage if:
(a) there are any dents in the cabinets
(b) the air and drain pipes are not straight
(c) there is any sign of oil on the skid or floor
(d) the refrigerant gauges show NO pressure
File these claims with the carrier immediately!
Otherwise, proceed with unpacking/uncrating the unit.
Environmental & Location Considerations
Following these guidelines will help insure that your new dryer will provide safe and reliable service.
Unless supplied for special conditions, air cooled dryers must be located in an area with an ambient
temperature between 50…100ºF (10…35ºC) and free from explosive and corrosive fumes. Three
(3) feet (92cm) of space must be allowed between all open grills, walls, or other objects.
Dryers for below freezing (31º, -0.5ºC) ambient temperatures are available with an optional
additional refrigeration condenser bypass valve.
If the dryer is installed in a confined area, an exhaust system must be provided to eliminate
recirculation of hot atmospheric air.
High ambient temperatures affect the outlet dew point of the dryer. For every 10º of ambient
temperature over 100ºF (35ºC) a decrease of 9% of dryer performance is encountered with air cooled
dryers. The unit must not operate in an ambient of over 115ºF (46ºC). If ambient temperature
conditions are over 100ºF (35º), water cooled dryers are recommended.
CAUTION

Section 3.0 – DRYER INSTALLATION
NEVER work on unit under pressure
NEVER work on unit when power is connected.
DO NOT over pressurize unit.
DO NOT pass air through the unit until it has been stabilized (operating 2 - 15 minutes).
The larger the dryer, the longer it takes to stabilize. Let unit cycle 2 – 3 times to stabilize.
Plumbing the Air Lines
The dryers are shipped ready to run. All connections are made to the outside of the cabinet.
Air piping must be supported independently of the dryer.
Direction of the air flow must be observed for proper installation. (Fig. 1)
General Layout
For Connections
(all connections are labeled)
H20 In/Out
(if water cooled)
Drain
Use unions or flange joints on inlet and outlet pipe connections. (Fig. 2)
If vibration is present, flexible metal hoses must be installed to prevent the vibration from being
transmitted to the dryer.
Install a bypass line and gate valve to permit isolation of the dryer from the air system. This is
done to provide easy service and/or removal of the dryer without interruption of air to the system.

USE TWO (2) WRENCHES WHEN CONNECTING DRYER TO PIPING. THIS WILL
PREVENT DAMAGE TO INTERNAL AIR LINES.
Recommended tools for Start-up
1. Roto-lock packing wrench (special)
2. Refridge service wrench
3. Small adjustable wrench
4. 6” adjustable wrench
5. Philips screw driver
6. Nut driver for panel removal

ELectrical Connection
Service Switch (On Models SMART CYCLE PLUS 300 to 3,000)
1. Remove side cover and locate electrical box.
2. Remove electric box cover from inside unit.
3. Locate the wires.
4. Locate hole on side of box, place and tighten connector, run wires through connector.
5. Using wire connectors, connect Black to Hot wire, White to Neutral and Green to Ground wire.
Refer to table above for voltage and wire colors.
6. Make sure no bare wire is exposed; replace box cover and screw closed.
7. Turn Service Switch “ON”.
8. Replace side covers.
Electrical Hook-up
Voltage Phase Wire Colors
115V Single Black, White, Green
230V Single Black, Red, Green
230V 3 Phase 3 Black, 1 Green
460V 3 Phase 3 Black, 1 Green
575V 3 Phase 3 Black, 1 Green
To be performed by a qualified person only.
Risk of serious injury or death. Before
connecting electrical power to the dryer check
for correct voltage and phase at the connection
box. All units must be externally grounded to
protect against sever electrical shock.
Toggle Switch shown in the “OFF” position as
shipped. Switch must remain in the “OFF”
position until ALL electrical wiring has been
completed.

Wire the dryer separately from the air compressor. The dryer must not cycle with the air
compressor. Refer to Section 6.0 – Start up Procedure.
Phase rotation is important if the dryer has a 3 phase condenser fan and/or the unit is
equipped with a scroll compressor (SMART CYCLE PLUS 500 – 1200). Fans must pull air
through condenser coil.
Read special TAG on scroll compressors fro proper rotation.
Observe dewpoint reading to verify rotation. If dewpoint reading does not drop within 30
seconds, turn unit off and reverse two electrical leads.
Crankcase heaters are pre-wired at the factory to line side of terminal box or contactor.
Heaters must be energized at all times, therefore the main disconnect must be left on at all
times except when servicing.

Section 4.0 - Controls
REFRIGERANT DRYER CONTROLLER
FEATURES AND OPERATIONS
(1) – RUN SELECT KEY: (MODE SELECTOR)
Push Key to toggle through the four modes of operation (‘AUTO’ Run Mode, ‘LOAD/UNLOAD’ Mode,
‘CYCLING’ Mode, and ‘OFF’). The Display ‘main screen’ will indicate all modes of operation along with the
current Dew Point measurement.
(2) – ALARM KEY: (RESET ALARMS)
When the ALARM Key red ‘LED’ is flashing, the system has experienced an alarm event. The Display will
indicate all alarms when they occur. Pushing the ALARM Key will attempt to clear the fault. Note with some
alarms, the system will need to be restarted.
(3) – DRAIN KEY: (OPERATE DRAIN)
When the ‘DRAIN’ Key is pressed, the drain solenoids will operate for the programmed time duration. (see
Settings, Drains). The green LED will illuminate indicating the drains are open.
(4) – LOAD KEY: (VIEW LOAD %)
Pushing the ‘LOAD’ Key will toggle the Display between indicating ‘Mode & Dew Point’ (standard), and,
‘Percent of Load’ (optionally) that the dryer is experiencing. The green LED will illuminate indicating the
display option is active.
