GENERAL
System Description
Outdoor-mounted, air-cooled, split-system air conditioner
unit suitable for ground or rooftop installation. Unit consists
of a hermetic compressor, an air-cooled coil, propeller-type
condenser fan, and a control box. Unit will discharge supply
air upward as shown on contract drawings. Unit will be used
in a refrigeration circuit to match up to a packaged fan coil
or coil unit.
Quality Assurance
Unit construction will comply with latest edition of ANSI/
ASHRAE and with NEC.
Unit will be constructed in accordance with UL standards
and will carry the UL label of approval. Unit will have c-UL
approval.
The condenser coil will be capable of withstanding the
following test method standards: Salt Spray test, ASTM
B117 1,000 hrs, and the Prohesion Test ASTM G85-A5
1,000 hrs.
Air-cooled condenser coils will be leak tested at 150 psig
(1034 KPa) and pressure tested at 300 psig (2068 KPa).
Unit constructed in ISO 9001 approved facility.
Delivery, Storage, and Handling
Unit will be shipped as single package only and is stored
and handled per unit manufacturer’s recommendations.
