12. Standard Specifications

UNIT - The unit shall be a multi-split system inverter-
driven heat pump air conditioner for application with
R410A or R32 refrigerants, and shall be composed of
ceiling type indoor units and an outdoor unit, with a
distributed refrigeration cycle, electrical components
and enclosing cabinets. Optional accessories shall
also be provided upon customer request. The indoor
unit shall be constructed for installation, and the
outdoor unit shall be completely weather-proofed for
outdoor installation. Both indoor unit and the outdoor
unit shall be properly assembled, internally piped and
wired, throughly tested, and charged with R410A or
R32 refrigerant at the factory and shall comply with
Japanese Industrial Standards and other Japanese
standardization statues.

galvanized steel sheet or finished steel sheet, baked
with synthetic resin-paint, with a plastic air panel
assembly for cassette type unit, and be constructed of
galvanized steel sheet for the in-the-ceiling duct type
unit.
REFRIGERATION CYCLE - The refrigeration
cycle shall be equipped with a heat exchanger, an
electronic expansion valve, solenoid valves and flare
connections.
INDOOR FAN AND FAN MOTOR - The indoor fan

OUTDOOR UNIT
CABINET - The cabinet shall be constructed of
galvanized steel sheet, baked with synthetic resin
paint. The service panel shall be easily removable for
service access to the electrical components and the
compressor section.
REFRIGERATION CYCLE - Each refrigeration cycle
shall be equipped with a scroll compressor, a solenoid
valve, a heat exchanger, a 4-Way valve and flare
connection parts.
COMPRESSOR PROTECTION - The compressor
shall be protected against breakdown by a quick
response overcurrent relay, a high pressure switch,
a wrap-around type oil heater and a discharge gas
thermistor.
OUTDOOR FAN AND FAN MOTOR - The outdoor
fan(s) shall be the plastic propeller type, dynamically
balanced, and the fan shall be directly driven by a
W motor for horizontal-flow air discharge. The
fan motor shall be permanently lubricated and be
protected from ingress of water.
OUTDOOR HEAT EXCHANGER - The heat
exchanger shall be the multi-pass, cross-finned tube
type, equipped with highly-efficient aluminum fins,
mechanically bonded to oxygen-free copper tubes.
The coil shall be cleaned, dehydrated and tested for
leakage at the factory.
CONTROL - All electrical control devices, shall be
enclosed in the indoor and outdoor units.
In addition to the compressor protection devices, the
indoor fan motor shall be equipped with an internal
thermostat. The outdoor fan motor shall be protected
by an internal thermostat. The indoor fan motor shall
be directly supplied with the power source from the
control circuit. The functions of these control devices
shall compose an electrical sequence of manual
starting and stopping, automatic continuous operation
whenever the room thermostat requires, and the
protection devices allow the operation.
CABINET - The cabinet shall be constructed of
galvanized steel sheet.
REFRIGERATION CYCLE - The refrigeration cycle
shall be equipped with solenoid valves and flare
connections to changeover the cycle in mediating
between outdoor unit and indoor unit.
