A.6.1 FEATURES
●Indoor (Main) Unit In case of PMH-P2BA
1. QUIET AS A MOUSE AND AS INCONSPICUOUS AS ONE TOO, THE PMH-P SERIES IS AN ATTRACTIVE, LIGHT-
WEIGHT MODEL THAT MOUNTS DIRECTLY INTO THE CEILING, BLENDING ALMOST SEAMLESSLY WITH NEARLY
ANY INTERIOR.
2. FRESH AIR INTAKE
Air recycled indefinitely can become stale and stagnant with air quality suffering significantly. Fresh air is the answer
and it is for this reason that the PMH-P series takes in air directly from outdoors. This fresh air intake allows you to
enjoy the comfort of crisp, refreshing air in the confines of your living or working space.
3. LIGHT AND COMPACT
The main unit weighs a measly 14kg and the panel a mere 3kg. This makes the PMH-P series one of the lightest in the
industry. The unit size is also quite small, having been standardized to a strikingly compact 854mm. All of this helps
make the chore of installation and maintenance that much simpler and easier.
4. AESTHETICALLY PLEASING
Nothing ruins the look of a carefully decorated room more than a poorly designed, bulky air conditioner. With the PMH-
P series, there is no need to worry. The unit mounts directly into the ceiling barely protruding into the living space for a
pleasant, stylish aesthetic.
Horizontal Air Outlet
Filters
Remove dust
and pollutants
from inhaled air.
Air intake
Inhales air from room.
Auto Air Swing Vane
Disperses air flow up and
down and adjusts the angle
of air flow direction.
Guide vane
Air flow can be changed to
horizontally by moving the Guide
vane to the left or right.
