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 is 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. (¼ -20screws, flat washers
& 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.

Dantherm Air Handling Inc Air Conditioner Preventative Maintenance Schedule
The internal/external filter (if applicable) shall be checked on a regular basis dependent on environmental conditions and replaced as necessary.
Periodically the coils should be cleaned. Once the coils become visibly coated with dust it is recommended that they be cleaned with a brush or
compressed air. Both sides of the coils should be inspected. The condenser coil may be washed with a commercial coil cleaning solution.
Under no circumstance must the access port covers be removed, adjusted, or tampered with other than by a certified technician.
All maintenance inspections must be recorded with time, date & details of activity.
Perform Self Test Function in acordance with Operation Manual. Complete general check of component mounting.
Condenser and evaporator blowers require no maintenance other then periodic inspection. In the event of dust build-up clean the blowers.
Rotating component bearings must be lubricated using SAE20 weight non detergent oil.
The cabinet can be cleaned with a sponge and warm, soapy water or a mild detergent. Do not use bleach, abrasive chemicals or harmful solvents.
Check for signs of corrosion and treat as necessary.
Check the drain and drain tube for obstructions. If a commercial drain solvent is used, flush out the drain pan and system with fresh water to prevent
corrosion.

iA/C T-Series Installation, Operating & Maintenance Manual
AC-6 iAC 6K 8K Manual Rev B Page 14 of 22
6.2 Evaporator and Condenser Coil Cleaning
Periodically the coils should be cleaned. No fixed period for cleaning can be provided due to the varying
environments in which the air conditioner may be installed. However once the coils become visibly coated
with dust it is recommended that they be cleaned with a brush or compressed air. Both sides of the coils
should be inspected regularly.
6.3 Compressor & Refrigerant System
The compressor is a hermetically sealed and factory lubricated unit and therefore requires no maintenance. If
the compressor fails it is recommended that the unit be returned to Dantherm Inc. for servicing. In the event
that the unit cannot be returned it is possible, using suitably qualified personnel, to repair the unit in the field.
If the refrigerant charge is lost the means of leakage should be established and repaired by a reputable
refrigeration repair company. Ports are provided for checking suction and discharge pressures and recharging
if required. The type of refrigerant and charge amount is detailed on the product label attached to the unit.
Note: Under no circumstance must the access port covers be removed, adjusted, or tampered with
other than by a certified technician.
6.4 Blowers
Condenser and evaporator blowers require no maintenance other then periodic inspection. In the event of
dust build-up clean the blowers.
6.5 Filters
The external filter shall be checked on a regular basis dependent on environmental conditions and replaced as
necessary.

6.6 Troubleshooting
The air conditioners are designed for trouble free life as long as the ambient filter (if applicable) is maintained
in a clean condition. To aid in service definition the service personnel can initially identify probable cause by
referring to the following trouble shooting chart.
