condensate pump safety-switch connection. With this feature the control monitors the condensate pump safety switch
and displays an error code if a fault occurs. The unit shall also provide non-volatile back up memory, where control
settings are maintained for an indefinite period during a power outage. When power is restored the equipment will
resume operation after a 3 minute compressor time delay. The controlVoltage shall be 24V AC generated from the
indoor units transformer.
part six “OutDOOr unit”
The outdoor unit shall be completely factory assembled, piped and wired. The cabinet shall be fabricated of 18 and 20
gauge aluminized steel, finished in off white. The paint shall be a corrosion inhibiting polyester powder-coated paint
tested to 2000 hours of salt spray. The cabinet shall also incorporate a black scratch and dent resistant injection mold-
ed from access panel. The unit shall be furnished with (1) large diameter, direct drive, high efficiency propeller type
fan. The motor shall be PSC type with internal overload protection and shall be permanently lubricated and resiliently
mounted for quiet operation. The fan shall be provided with a guard to prevent contact with moving parts. The compres-
sor shall be of the high performance rotary type with Duratec package consisting of an oversized accumulator, factory
installed solid core filter drier and thermal overloads. The compressor shall be mounted as to avoid the transmission
of vibration. The condenser shall have easy access hose connections at 45° from valve body. The refrigeration system
shall be equipped with loss of charge switch, and have the capability to operate with a maximum height difference of 35
feet and overall refrigerant tubing length of 100 feet between indoor and outdoor sections without the need for line size
changes of additional oil. The condenser coil shall be U-shaped and protected by a wire coil guard. Coil construction
is seamless copper tubing with enhanced aluminum fins. The tubes are mechanically expanded for secure bonding to
the fin. The heating expansion is controlled by a TXV in the outdoor unit. The unit electrical power shall be 208/230V or
115V, 1 phase, 60 Hertz. The system shall be capable of operation withinVoltage limits of 208/230V or 115V +/- 10%.
