1. Features

Cabinet The enclosure is built with galvanized steel and coated with a protective paint. It is convenient for transportation and installation and fully insulated from high temperature and high voltage, in order to avoid hazardous risks. Filter Factory installed filter can be cleaned and reinstalled for air filtration. Drainage Enhancing primary and second drainage design allows complete drainage to improve in-house air quality. Protection Factory installed coil temperature sensor providing effective protection of the system. Expansion Device The Valve Expansion Device is durable and guarantees stable operation. Application Multiple airflow positions design, which includes up-flow, horizontal, enables an extensive share of the air exchanged. Performance This series is designed and tested by ARI 210/240 standard. Controller This series can match Honeywell thermostat.

MCAC-UTSM-2008-02 Features

1. Features ¨ Quality condenser coils – The coil is constructed of enhanced inner-groove copper tube and

aluminum fins. ¨ Durable cabinet – Cabinet is made of galvanized steel. It provides a better paint to steel bond, which

resists corrosion and rust creeping. ¨ Lower installation cost – Installation time and costs are reduced by easy wiring connections. The

small base dimension means less space is required on the ground or roof for locating. ¨ Top discharge – The warm air from the top mounted fan is blown up away from the structure and this

allows compact location. ¨ Easy service access - Fully exposed refrigerant connections and a single panel covering the

electrical controls makes servicing easy. ¨ Flat-roofed design–Easy to stack and transport. ¨ Compact design– Smaller dimensions and larger stuffing quantity. ¨ 24V low voltage control– Safer for person.
