1. Transport / Inspection
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, air cooled dryers must be located in an area
with an ambient temperature between 41 - 100ºF (5-38ºC) and free from explosive and
corrosive fumes. Three (3) feet (92cm) of space must be allowed between all open grills.
If the dryer is installed in a conned area, an exhaust system must be provided to
eliminate re-circulation of hot atmospheric air.
• With air cooled dryers, high ambient temperatures affect the outlet dewpoint of the dryer.
The unit must not operate in an ambient of over 115ºF (46ºC). If ambient temperature
conditions are over 100ºF (38ºC), dryer capacity will be reduced. To get dryer capacity at
elevated ambient temperature use the correction factors.
• Unit must be installed indoors.
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
5 minutes)
2.1 Plumbing the Air Lines
The dryers are shipped ready to run.

4 - Rev. E
PNC200 - PNC1200 USER GUIDE
• Air piping must be supported independently of the dryer.
• A properly sized Parker pre-lter is recommended ahead of the dryer to maintain
optimal performance and warranty validation. It should be installed as close to the
dryer as possible. Any piping between the pre-lter and inlet of the dryer must be
stainless steel, copper, galvanized, aluminum or other non-corroding material. A
union between the pre-lter and the dryer is recommended for ease of assembly
and change-out of lter element. Please refer to section 10.1 for proper pre-lter
selection.
• Direction of the air ow must be observed for proper installation.
• 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.
• Make the connection to the draining system, avoiding connection in a closed circuit
shared by other pressurized discharge lines. Check the correct ow of condensate
discharges. Dispose of all condensate in conformity with current local environment
regulations.
• Set drain time intervals to ensure complete condensate removal from dryer.
2.2 Electrical Connections
To be performed by a qualied person only. Risk of serious injury or death. Observe
Lock out/Tag Out Procedure: Disconnect, lock out and tag all power at source prior
to attempting repairs or adjustments to rotating machinery and prior to handling any
ungrounded conductors.
Provide breach and short circuit protection as well as disconnect means per local and
national codes.
Before connecting electrical power to the dryer check for correct voltage at the
connection box. Panel Removal: To remove front or side panels, remove screws and lift
panel up, then pull out the bottom.
All units must be externally grounded to protect against severe electrical shock.
1. Remove electric box cover from inside unit.
2. Locate the wires.
3. Locate hole on side of box, place and tighten connector, run wires through
connector.
4. Make sure no bare wire is exposed; replace box cover and screw closed.
5. Line input wiring connections are made to line side on compressor contactor
6. Should the compressor not start, see start up procedure.
Wire the dryer separately from the air compressor. The dryer must not cycle
with the air compressor.
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 8 hours prior to start–up and after prolonged shut down. The power must
be left on at all times except when servicing.

3. Controls - Standard on all models
• Dryer ON/OFF Switch
• Dryer POWER Light
• HIGH REFRIGERANT PRESSURE ALARM
• LOW REFRIGERANT PRESSURE ALARM
• DEWPOINT TEMPERATURE INDICATOR
• Adjustable time drain module mounted directly on drain solenoid
• Refrigerant Suction Guage

PNC200 - PNC1200 USER GUIDE
4. Start Up Procedures
There should be NO air ow through the dryer before or during start-up. It is recommended that
the dryer be installed with bypass piping to better service the unit. Inlet & outlet valves to the
dryer should be closed with the by-pass valve open.
1. After electrical connection (Section 2), apply power.
2. Leave power on for 8 hours before attempting to start (POWER light on). This allows the
crankcase heater time to warm the refrigerant compressor oil and dissipate any refrigerant
migration that can occur during storage. Failure can result in damage to the compressor
and will void the warranty.
3. Verify suction pressure gauge reads above 80 psi (5.5 bar). If it is less, the dryer may have a
refrigerant leak. This may be the result of shipping damage – see section 1.0.
4. Switch unit on. ON/OFF indicator will light.
5. Do not pass air through the dryer until it stabilizes (Typically 5 minutes).
6. Once the dryer stabilizes, you can now introduce compressed air to the dryer.
SLOWLY pressurize the dryer. Once completed slowly open the outlet valve, then close the
bypass valve. The dryer is now on line.
7. Clean the condensate drain strainer after the rst 8 hours of operation.
(See section 5.0 Routine Maintenance)
8. Restart dryer using this procedure after maintenance, power outage or prolonged periods of
shutdown.
4.1 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 (5-38ºC)
6. Keep inlet temperature under 101ºF (38ºC)
7. Check and clean condensate drain strainer regularly.

7 - Rev. E
PNC200 - PNC1200 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.
• The strainer should be checked weekly.
Pre-filtration per installation instructions:
• Parker pre-lter should be installed directly upstream from the dryer.
• The pre-lter should be changed every 6-12 months to prevent dryer fouling and
prevent damage.

6. Maintenance Schedule
The maintenance chart below indicates the components that should be checked while per-
forming routine maintenance on the dryer. The chart also indicates how often a specic check

6.1 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.
Refer to lock-out/tag-out procedures.
Upon completion of the maintenance tasks be sure that the machine has been
properly reassembled prior to restarting and reintroducing air.

Adjustments should only be made under the guidance of a certied refrigeration technician. 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.
7.1 Refrigerant Charging Procedure
• Charge liquid refrigerant only. Do not use vapor.
• The dryer needs to be pulled into a vacuum (500 micron minimum) for 30 minutes.
• Charge liquid refrigerant into the high side refrigeration access valve located in the line
on the outlet of the condenser.
• The full charge may not be accepted. If this occurs, the dryer can be started and the
remainder of the charge should be metered into the compressor suction service valve.
