1 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) there is any sign of oil on the skid or oor
(c) the refrigerant gauge shows NO pressure
(Upper right side – look for hole in packing)
File these claims with the carrier immediately!
Otherwise, proceed with unpacking/uncrating the unit.
1.1 Environmental & Location Considerations
Following these guidelines will help insure that your new dryer will provide safe and
reliable service.
• Unless supplied for special conditions, all SCP dryers must be located indoors in
an area with an ambient temperature between 41 - 100ºF (5-37.7ºC) and free from
explosive and corrosive fumes. Three (3) feet (92cm) of space must be allowed
between all open grills, walls, or other objects.
If the dryer is installed in a conned area, an exhaust system must be provided to
eliminate re-circulation of hot atmospheric air.
• High ambient temperatures affect the outlet dew point of the dryer. For every
10º of ambient temperature over 100ºF (37.7ºC) a decrease of 10% 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 (37.7º), water cooled dryers are recommended.
• Unit must be installed indoors.

4 - REV. B
SCP 1200 - 3000 USER GUIDE
2. 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 about 15-20
minutes)
2.1 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 ow must be observed for proper installation.
• Use unions or ange joints on inlet and outlet pipe connections.
• If vibration is present, exible metal hoses must be installed to prevent the
vibration from being transmitted to the dryer.
• Install a bypass line and gate valves 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) WRENCEHS WHEN CONNECTING DRYER TO PIPING. THIS
WILL PREVENT DAMAGE TO INTERNAL AIR LINES.

2.2 Electrical Connections
To be performed by a qualied 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 severe electrical shock.

2.3 Electrical Hook-up
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.
Wire the dryer separately from the air compressor. The dryer must not cycle
with the air compressor.
Phase rotation is important if the dryer has a 3 phase condenser (SCP3000).
Fans must pull air through condenser coil.
Crankcase heaters are pre-wired from the factory to the line side of the
compressor contactor. When power is applied to the dryer, the heater will
energize. Heater must be energized for 12 hours prior to start–up and after
prolonged shut down. The power must be left on at all times except when
servicing.

combination of very bad dew point and or overloaded. The other side of the spectrum
would be only one GREEN LED illuminated; indicating less then (<10%) ten percent
capacity is being utilized and all is OK.
(10) – MAINTENANCE MONITOR:
The controller will remind the user to perform maintenance on the dryer every six
month. The Display will indicate (and the ALARM LED will ash), the statement
“CHANGE FILTER.” IMPORTANT – The user should change the coalescing lter on a
regular basis. Also do all other recommended maintenance (see maintenance section
of the Operating Manual) at this time.

4. Start-Up Procedure
There should be NO air ow through the dryer before or during start-up. It is recommened
that the dryer be installed with bypass piping to better service the unit.
4.1 Smart Cycle Plus 1200 – 3000
1. After electrical connection (Refer to Section 3), apply power.
2. 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.
3. Remove side panel from unit.
4. Some units are shipped with the refrigeration service valve tagged. These
tagged service valves must not be opened until the dryer is ready to be
started and the main power is permanently applied. Only tagged service
valves must be opened.
5. Locate tagged service valves and remove end cap from valve stem.
(Fig. 3 below)

14 - REV. B
SCP 1200 - 3000 USER GUIDE
6. Using a refrigeration service or small crescent wrench, turn the valve stem
counterclockwise until it stops. Occasionally, it may be necessary to re-tighten
the packing nut (turn clockwise) if a leak is noticed. The valve will now be fully
opened. (Fig. 3)
7. Replace cap.
8. Once the crankcase heater has been pre-heated, pressure the RUN SELECT
button on the control panel to start the dryer.
9. If the storage conditions were adverse (for example very cooled) the refrigeration
compressor may make a loud metallic hammering noise. If this happens, turn
the dryer off at the panel and wait 60 seconds. Then turn the dryer back on.
Repeat this procedure until the refrigeration compressor runs smoothly. The
dewpoint should start to drop towards the set point.
Do not pass air through the dryer until it is stabilized.
(Unit cycles 2 – 3 times)
10. With the dryer turned on from the control panel, and is stabilized, you can now
introduce compressed air to the dryer.
11. Check the automatic drain for proper operation. Drain should open at regular
intervals based on the drain control settings.
Clean Y-Strainer on drains after the rst 4 hours of operation. (See Section 5.0, Fig. 4)
12. Restart dryer using this procedure after maintenance, power outage or prolonged
periods of shutdown.
4.2 When Operating Dryer
1. Turn dryer On and Off at control panel only.
2. Keep power to unit at all times except when servicing.
3. Start dryer prior to allowing air ow through unit.
4. Clean condenser when necessary.
5. Maintain ambient temperature between 41-100ºF (5-37.7ºC)
6. Keep inlet temperature under 101ºF (38ºC)
7. Check and clean Y-strainer regularly.
8. NEVER allow dryer to cycle ON/OFF with air compressor.

15 - REV. B
SCP 1200 - 3000 USER GUIDE
5. Routine Maintenance
The air cooled condenser must be kept clean. Inspect on a regular basis for dirt or
debris that might accumulate. Remove any debris immediately.
It is recommended that the drain and solenoid be checked weekly for proper functioning.
The Y-strainer should be checked and screen cleaned monthly. (Fig. 4)
It is not advisable to tamper with the other adjustments unless you are familiar with
refrigeration. The controls interact with each other and, although the effect of an adjustment
may not be immediately obvious, it will affect the dryer’s performance.
CHARGE LIQUID REFRIGERANT ONLY, DO NOT CHARGE WITH VAPOR!
• See tag for correct refrigerant charge.
• Unit needs to be pulled into vacuum 500 micron (minimum)
• The full charge might not be accepted. If this occurs, the unit can be started and then
the remainder of the charge should be slowly metered into the suction side (Suction side
is always the inlet to compressor side).
