Ensure that all panels can be removed for service as required.
CAUTION! Using old refrigerant lines with new Air Conditioner installation
This air conditioner adopts the new HFC refrigerant (R410A) which does not destroy ozone layer. R410A
refrigerant operates at approximately 1.6 times the pressure of refrigerant R22. Accompanied with the
adoption of the new refrigerant, the refrigeration lubricating oil has also been changed. During installation work
be sure that water, dust, former refrigerant, or refrigeration lubricating oil does not enter into the new type
refrigerant R410A air conditioner system. The system must not be left open to the atmosphere for any reason
for any period of time as the systems oil quickly absorbs moisture and will contaminate and damage the system.
To prevent mixing of refrigerant or refrigeration lubricating oil, the sizes of connecting sections of charging port
on main unit and installation tools are different from those used for the conventional refrigerant units.
Accordingly, special tools are required for the new refrigerant (R410A) units. For connecting pipes use new
and clean piping materials with high pressure fittings made for R410A only. The best and recommended
solution is not to use the existing line sets because there may be some problems with pressure fittings and
possible impurities in the existing piping.
Certification
AII Ductless Mini Splits are certified by ETL under UL standard 1995, 4th Edition, Rev. Oct 14, 2011.
Performance is certified by CSA standard C22.2 No. 236-05, 4th Edition, Rev. Oct 14, 2011
Operating Limit
Outdoor operating temperature range: 5°F to 122°F
– Cooling, 5°F to 86°F – Heating.
Controls and Components
Units are supplied with a wireless remote controller, which communicates with the unit microprocessor
controller. The return air temperature sensor mounted on the unit then controls the unit operation.
Several modes of operation are available to the end user depending on the type of comfort required. AII unit
operating functions are controlled via the remote controller.
Optional Controls and Components
Low Ambient Controller is included for use in Server Rooms or in Commercial applications.
Condensate Pump:
Condensate pump can be used when gravity drain is not practical.
To power a condensate pump connect to outdoor unit input power supply ONLY. Do not connect to indoor unit.
Decorative Channel:
Route the bundled piping and wiring to the outdoor unit and connect per the OUTDOOR
UNIT installation instructions.
Our
Plastic-Duct
piping and wiring duct work provides a convenient and professional looking system to route
and protect the pipes and wires. Please see the illustrations below:
