units. Electrical wire & connections to outdoor section, and between indoor & outdoor section(s),
shall be sized, installed & grounded by the installer in conformance with the National Electrical
Code (N.E.C.), local codes, as well as, manufacturer’s instructions.

System(s) shall be equipped with a microprocessor control system, utilizing an infrared remote
controller with LCD display that provides access to all system functions, and transmits room
conditions & programs to the indoor microprocessor every 3 minutes. Infrared remote controller
shall be capable of operating system mounted up to 26’ from the indoor section, according to
manufacturer’s recommendations & instructions. System(s) shall have the capability of continuous
operation in the case of a lost or damaged remote controller, utilizing a factory installed, integral
manual switch in conjunction with the system microprocessor.

1A) System Infrared Remote Controller Functions will include: system mode selection,
programmable temperature control, 24 hour programmable timer, one (1) hour off timer,
automatic three (3) speed indoor fan speed control, constant fan speed selection, night setback
mode, automatic sweep/flap control, user selectable room temperature sensor located on either
infrared remote controller or indoor unit, multiple system control using a single controller.

1B) System Features will include: Sanyo high efficiency, rotary compressor, with suction line
accumulator, cap tube refrigerant control, light duty condensate pump, indoor coil freeze
protection, built-in auto restart after power failure, short cycle time delay, low ambient cooling
operation to zero degrees outdoor air temperature (selected systems), automatic indoor fan speed,
washable anti-mold poly filters, indoor mounted operation selector & lamp showing operation,
standby & timer modes, with start up test mode & manual on/off switch.

Low Ambient System(s) shall be capable of operating in the cooling mode down to zero (0)
degrees F. outdoor temperature.

1C) INSTALLATION

System(s) shall be installed according to manufacturer’s instruct ions & recommendations, as well
as, all governing local & national codes. System(s), as well as the infrared remote controller, shall
be mounted & placed as shown on plans within all minimum clearances as specified by
manufacturer’s instructions, & secured to provide for safe operation. Refriger ant tubing size shall
not vary from manufacturer’s specifications, and shall be properly secured & insulated. Installer
shall insulate both liquid & suction lines individually. Electrical wiring shall be sized & installed
according to manufacturer’s instructions & in conformance with the National Electric Code (NEC)
& local codes. Outdoor condensers shall be mounted & secured to accommodate for extreme
weather conditions. Distance between indoor & outdoor unit(s) shall not exceed manufacturer’s
specifications.

2) OUTDOOR CONDENSING SECTION – SANYO MODELS – C1852, CL1852
Outdoor condensing section(s) shall be factory assembled, wired, piped & pre-charged with a start

up amount of R-22 refrigerant. Unit(s) shall be constructed of G90 galvannealed steel with
corrosion inhibiting, powder coated paint. Unit(s) shall be furnished with a high efficiency, Sanyo
rotary compressor with internal overload protection, securely mounted with vibration isolators to
reduce noise & vibration. Condenser coil heat exchanger shall be constructed of nonferrous, rifled
copper tubing with enhanced aluminum slit fins mechanically bonded to the copper. A suction line
accumulator, a coil temperature sensor & c ap tube metering device shall be factory installed. Fan
motor(s) shall be direct drive with internal overload protection, permanent lubrication, with
propeller type fans, mounted for horizontal air discharge. Brass valves with refrigeration flare
connections & flare nuts, & service ports shall be fa ctory mounted, externally for easy access. The
unit(s) shall be test started by the manufacturer at their factory prior to shipment for installation.

Low Ambient outdoor section(s) shall contain a printed circuit board, factory mounted & wired,
to assist in control of low ambient operation. Unit(s) shall be able to operate in the A/C mode
down to zero (0) degrees Fahrenheit outdoor temperature. A factory installed 20 watt crankcase
heater shall provide additional compressor protection.
