AIR CONDITIONER INSTALLATION

When installing air conditioner at glass window or thin partition,
fix the vertical and side supporting bar to the concrete wall in order to
support the weight of the air-conditioner and reduce the vibration that
is being transferred to the glass window or thin partition.
This can minimize the noise problem caused by improper installation.
Proposed to use 1/8” x 1-1/4” “angle-aluminium for
installation frame and side supporting bar.
This air conditioner employs a “Slinger-Up System” which is designed to splash the condensed water on the condenser coil
for maximum cooling efficiency, thus producing a splashing sound. If the splashing sound annoys you, you can provide an
outside drainage by using the following the procedure which may, cause a small loss of performance.
NOTE: If the unit is installed at a coastal area, drainage of condensed water is recommended to prevent easy condenser corrosion.
