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 will be rated in accordance with the latest edition of
ARI Standard 240.
Unit will be certified for capacity and efficiency, and listed
in the latest ARI directory.
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.
Unit cabinet will be capable of withstanding Federal Test
Method Standard No. 141 (Method 6061) 500-hr salt spray
test.
Air-cooled condenser coils will be leak tested at 217 psig
and pressure tested at 450 psig.
Delivery, Storage, and Handling
Unit will be shipped as single package only and is stored
and handled per unit manufacturer’s recommendations.
Warranty (for inclusion by specifying engineer)
U.S. and Canada only.
