DESCRIPTION The 558D/559F electric cooling rooftop units are designed to deliver optimum performance and reliability in a commercial rooftop unit. The 3 to 25 ton units are one-piece electric cooling units that are prewired and precharged with R-22 at the factory , making jobsite installation easy .
DUAL COMPRESSORS AND DUAL REFRIGERA TION CIR- CUITS (090-150 and 216-300 Units) are provided. T wo com- pressors, each on its own independent circuit, provide standby reliability and high operating eff iciency . ADV ANCED DESIGN of evaporator and condenser coils pro- vides optimum heat transfer and cooling eff iciency .
Controls Upgrade Kit (036-150 Units) — The controls kit in- cludes high-pressure, loss-of-charge/low-pressure, and freeze protection cutout switches. The high-pressure and loss-of- charge/low-pressure switches can be easily added by screwing the switches onto Schrader-type fittings provided on the refrig- erant lines.
Head Pressure Control — Kit consists of an outdoor-air ther- mostat that permits adequate head pressure control during cooling operation at low outdoor-ambient temperatures. Refer to T rade Prices for more details or contact your local representative.
