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: Copeland high efficiency, scroll compressor, with a suction
line accumulator, liquid sub-cooler, a liquid line strainer, cap tube refrigerant control, indoor coil

freeze protection, built-in auto restart after power failure, high pressure switch, short cycle time
delay, automatic low ambient fan operation, low ambient cooling operation to zero degrees
(selected systems), automatic indoor fan speed determined by system microprocessor, washable
long-life anti-mold poly filters, indoor mounted operation selector & lamp showing operation,
standby & timer modes, with start up test mode & manual on/off switch. System(s) shall be
capable of utilizing Fresh Outside Air (OSA).
Low Ambient System 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 manufacture r’s instructions & 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 on Heat Pump & Low Ambient specified
system(s). Electrical wiring shall be sized & instal led according to manufacturer’s instructi ons &
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 Model– C4232A, CL4232A
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,
Copeland scroll 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. Unit(s) shall include a suction line accumulator, a condenser coil temperature sensor, a
liquid, high side sub-cooler, as well as a high pressure switch. Dual (2) fan motor(s) shall be direct
drive with internal overload protection, permanent lubrication, multi-speed for low ambient
operation, with propeller type fans, mounted for horizontal air discharge. Brass valves with
refrigeration flare connections & flare nuts, & service ports shall be factory mounted for easy
access. The unit(s) shall be test started by the manufactu rer at their factory prior to shipment for
installation.
Low Ambient outdoor section(s) shall contain a printed circuit board, factory mounted & wired.
Unit(s) shall be able to operate in the A/C mode down to zero (0) degrees Fahrenheit outdoor
temperature. A factory installed, 30 watt crankcase heater shall provide additional compressor
protection.
3) INDOOR EVAPORATOR SECTION – SANYO MODELS – TS4232
