7. STABLE COOLING EVEN AT OUTDOOR TEMPERATURES AS LOW AS 23˚F MAKES YEAR-ROUND AIR-CONDITIONING POSSIBLE
The microprocessor automatically adjusts fan speed in accordance with outdoor temperature to maintain the coolant at an
even condensing temperature. The result is smooth, efficient cooling even when temperatures outdoors drop as low as 23˚F.
This makes the unit ideal for a wide range of specialised cooling needs, such as rooms with many office machines or com-
puters and areas subject to strong sunlight.
5. IMPROVING EFFICIENCY OF PIPING WORK
11Removed the knockout work by separating the piping
space from the air outlet for efficiency of the piping work.
wKnockout work is needed for the top part. When option-
al drain-up machine is installed, the refrigerant pipe
exits out from the top.
wPlease move the rubber plug for the unit to the right joint
when drainage pipe exits from the left side.
22Improved the flexibility by making it possible for
drainage pipe to exit not only from the right side
back but also from the left side back.
