1GENERAL SAFETY & WARNING INSTRUCTIONS
Certain parts of electrical systems are inevitably live or have a high operating temperatures. Observe
caution at all times.
Failure to observe these conditions and installation instructions can cause injury and damage.
The system is to be installed and maintained only by trained and qualified personnel.
Do not apply power until all ground connections have been made.
The unit is fitted with pressed and folded metal parts, which could have sheared metal edges. Be cautious
handling the unit, especially when working in poorly accessible places.
Check that no tools, test equipment, torches etc. have been left in or on the equipment on completion of
work.
Ensure the cover(s) and all mounting hardware are firmly secured before leaving installation.
All cable and connectors must conform to UL standards.
Most models are UL recognized and tested to UL484. It will comply where necessary with the safety
requirements as defined in UL484.
When servicing the unit, do not remove the cover(s) for 5 minutes after switching the unit off to allow
pipe work (compressor discharge) to cool.
2UNPACKING, HANDLING & INITIAL INSPECTION
The air conditioner should be inspected on initial delivery and any damage to packaging noted. The unit
should be maintained in the upright position at all times. Special consideration should be given to correctness
of external packing damage or abrasion, loose components, surface marks and oil leakage. Any damage
should be noted on the freight bill and a claim should be immediately filed with the freight company. All
packaging materials should be retained for inspection.
Under no circumstances must the unit be inverted, as the oil will drain from the compressor into the
refrigerant piping system.
Do not attempt to operate the unit if it appears to be damaged from being dropped.
Do not attempt to operate the unit in a horizontal position (on its side, back or front). Place the unit in an
upright or vertical position for at least 5 minutes before operating.

4.3 Gasket installation
4.4 Installation and Connections
The enclosure shall be checked for correctness of cutouts, mounting holes and electrical supply.
Install the gaskets as shown in section 4.3. A gasket kit is provided with each unit.
Utilize an appropriate and safe lifting device.
Mount the Air Conditioner to the cabinet using hardware supplied with unit. (8 ¼-20screws, 8 flat
washers & 8 lock washers). Custom air conditioner may require different size of bolts and washers.
The maximum torque is 130 in-lbs with a recommended assembly torque of 75 in-lbs.
Connect the Air Conditioning Unit power lead to the mains supply located in the cabinet/enclosure.
Refer to the product label on the bottom right hand side panel of the unit for the proper voltage/amp
requirement. Make sure a properly grounded power supply is used. All installations are to be
completed in accordance with local NEC codes and guidelines.
The electrical circuit should be protected by a slow blow breaker or fuse of suitable rating.
The alarm is a Form C type relay (50 VDC / 0.1A Max). The connections for alarm are the red
(Common), black (Normally open) and white (Normally closed) wires only. The green wire is not used.
If the interconnect function is to be used, connect the black and red wires on the small two wire
interconnect cable to the corresponding interconnect cable supplied with each unit. Contact Dantherm
for additional information.
The Air Conditioning Unit is supplied with a condensate drain hose. Secure the hose to the drain nipple
and route away to suitable position/location.
4.5 Unit Operation
Turn the main power on to unit, the evaporator fan (internal circuit) should run immediately.
Functionality may be verified by initiating “TEST” sequence located in section 5.5.2 of this manual.
Access the controller by removing the unit front cover.
Check for the following:
Airflow through both condenser and evaporator
Abnormal vibration

Temperature of cabinet supply air should be less than 70oF (21oC) when the
ambient air is 80oF (27oC) or below.
Replace the cover after completion.
5USACG-6 INTELLIGENT CONTROLLER OPERATION
The intelligent controller installed in the air conditioner has two levels of operation. Limited functionality
from the integrated four position LED display allows the user to debug the system, change heating set point,
change cooling set point, and change unit of measure (ºF or ºC). More settings are available to customize a
unit for an application by accessing the controller via the RS-232 serial port connected to a PC with
HyperTerminal. Access the controller by removing the unit front cover.
Adjusting the factory controller settings may alter performance and affect warranty.

displayed. The following faults may be shown:
F=01 (missing compressor current)
F=02 (High Pressure)
F=03 (Low Pressure after start up)
F=04 (Low Pressure before start up)
F=05 (High Temperature)
F=06 (Low Temperature)
F=07 (Missing Sensor)
