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 floor
(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 &amp; 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 - 100&ordm;F (5-37.7&ordm;C) 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 confined 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
10&ordm; of ambient temperature over 100&ordm;F (37.7&ordm;C) a decrease of 10% of dryer
performance is encountered with air cooled dryers. The unit must not operate
in an ambient of over 115&ordm;F (46&ordm;C). If ambient temperature conditions are over
100&ordm;F (37.7&ordm;), water cooled dryers are recommended.
•
Unit must be installed indoors.

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 flow must be observed for proper installation.
•
Use unions or flange joints on inlet and outlet pipe connections.
•
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 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.

SCP 1200 - 3000 USER GUIDE
2.2
Electrical Connections
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 severe electrical shock.

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.

Start-Up Procedure
There should be NO air flow 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)
13 - 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 first 4 hours of operation. (See Section 5.0, Fig. 4)
12.
4.2
Restart dryer using this procedure after maintenance, power outage or prolonged
periods of shutdown.
When Operating Dryer

3.
4.
5.
6.
7.
8.
Turn dryer On and Off at control panel only.
Keep power to unit at all times except when servicing.
Start dryer prior to allowing air flow through unit.
Clean condenser when necessary.
Maintain ambient temperature between 41-100&ordm;F (5-37.7&ordm;C)
Keep inlet temperature under 101&ordm;F (38&ordm;C)
Check and clean Y-strainer regularly.
NEVER allow dryer to cycle ON/OFF with air compressor.
14 - 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).

STARTUP NULL SCREEN-----------------------------------------------------------------Upon initialization, the display shows the “type” of dryer the Control Center is configured to control.
An example:
Company
REFRIG DRYER (R404A)
S/N B00001 V2.12IR4
This is a fixed configuration. Once assigned to a dryer: the Control Center will never be
changed to any of the other configurations. Note that the Control Center Serial Number,
Refrigerant Type and Firmware Version are also displayed on the null, initialization screen.
PRE-SETUP
Prior to starting up the dryer, the DISPLAY VALUES button may be selected to
view groupings of sensors (use the up/down arrows to scroll through the list)
Depress the Display Values button a second time, or the Alarm RESET button to
return to the Main Screen. Also, all of the other screens and menus can be viewed
by using the up/down arrows. Simply position any particular menu choice into
view and advance a menu level by depressing the SET button. Returning to the Main
Screen can be achieved at any time by depressing the Alarm RESET button.
These screens may be viewed at any time, and at any state of operation.

If Timed is selected, the drain will activate to the “Interval” time setting for the period of time indicated in the `Duration’ time setting.
If DEMAND is selected, the drain will operate for the period of time indicated in the `Duration’ time setting, when a drain input signal is sensed from the demand drain float. A DRAIN FAULT Alarm can occur if float doesnot respond as expected. When a fault is detected, the drain solenoid will be `pulsed’ for ten minutes in attempt to clear the faulted drain.
The `Auto Test’ feature will operate the drain for the period of time indicated in the Duration setting at the specifiedInterval. This feature is intended to prevent sediment buildup by activating the drain periodically and `blowing out’ any possible debris.

Maintenance Procedures
Before performing any maintenance on the machine ensure that air pressure is vented from the system. Also make sure that personnel performing the mainte
nance have read the maintenance section of the manual.
Some of the maintenance tasks will require the refrigeration system to run, but when not required, turn the unit off before proceeding.
Upon completion of the maintenance tasks be sure that the machine has been properly reassembled prior to restarting and reintroducing air.

Routine Maintenance
This section covers the various components that require periodic maintenance
and/or replacement.
Coalescing Filter Element
The coalescing filter element should be check Bi-Annually. On units with the standard
control panel, check the pressure drop across the unit by using air pressure gauges
upstream and downstream of the dryer using the closest possible gauges to the dryer. If
it is determined that there is a high pressure drop across the machine, remove the filter
element from the machine and inspect it. If the filter is dirty, replace it. Ensure that air
pressure is removed from the machine prior to removing the filter element. On units that
have the Control Center option installed the filter differential can be checked on the control
board.
The coalescing element should be changed annually. To change the filter element:
•
•
•
•
•
•
•
•
De-pressurize the dryer.
Remove the bolts that secure the filter housing cover.
Remove the wing nut that secures the filter cap to the element.
Remove the filter cap.
Remove the existing element from the housing.
Install the replacement element.
Reinstall the filter cap and wing nut
Reinstall the filter cover.
Condensing Coil (Air Cooled Units)
The condensing coil should be cleaned weekly. Ensure that air pressure is removed from
the system prior to cleaning the condenser. The condenser can be cleaned by using a vacuum or compressed air. If the condenser is not clean after it is blown out with compressed
air or vacuumed, contact the factory for assistance.
Condenser (Water Cooled Units)
The water cooled condenser should be checked and cleaned annually if necessary. To
check the condenser, water flow to the condenser should be shut off, air flow to the machine should be shut off, and the unit should be taken out of a run mode. The end bonnets
then need to be removed exposing the tube side of the condenser. The tube side should be
inspected for any debris and cleaned. If soft deposits are found they can be cleaned using
a pneumatic tube cleaning gun which forces plugs down the tubes. Some have a brush
between two rubber plugs and others are specially designed plugs which scrape the tube
walls as they travel down the tube. If scale is found special equipment is required to clean
the tubes. These cleaning systems utilize a flexible shaft which rotates a brush as it is fed

down the tube, they can also simultaneously flush out the tubes with water. There is a wide
variety of brushes and tools available that attach to the shaft to clean both soft and hard
deposits.
Drain Line Y-Strainer (See Section 5.0, Fig. 4)
The drain line y-strainer should be cleaned weekly. Air flow and air pressure should be removed from system before proceeding. To clean the y-strainer:
•
Turn the ball valve on the strainer assembly to the closed position
•
Remove threaded cap at the end of the ball valve assembly.
•
Clean the screen inside of the cap by rinsing it under water.
•
Reinstall the screen and cap
•
Return the ball valve to the open position
High Pressure, Low Pressure, &amp; Fan Control (AC units only)
The refrigeration pressure switches should be checked monthly to ensure that they are adjusted to the proper settings. Please refer to the applicable electrical drawings for your unit.
Compressor Oil Level
The oil level in the compressor should be checked daily. The refrigeration system should
never need oil unless the system is leaking or has been recently repaired. If it is determined
that the system needs oil, do the following:
•
Run the dryer for a minimum of 2 minutes, if there is not a visible level of oil in the
sight glass, proceed to the next step, if there is an oil level, DO NOT add oil to
the system.
•
Using the appropriate oil pump add the proper oil (POE forR134 and R404
refriger ant) using the Schrader valve on the suction side of the compressor.
•
Add oil until there is a visible level in the sight glass with the compressor running.
