2.3. Easy installation
2.3.1. Easy suspension
•
• •
• A suspension bolt fixing bracket with 4-point support is
attached to the main unit, which increases the space
available for installation.
2.3.2. Two installation methods :
standard and wall
•
• •
• In addition to the standard (1) ceiling installation, a wall (2)
installation method (using a wall-hanging bracket) is
available for cases where the ceiling is too high for the main
unit to be suspended.
2.4. Piping
2.4.1. 3-direction pipe lead-out
•
• •
• The refrigerant piping can lead out in one of three directions
(right, rear-right and top-right), and the drain pipe direction
can be selected from four directions (right, rear-right, left
and rear-left).
2.5. Easy maintenance
2.5.1. Long life filter (standard
equipment)
•
• •
• In general office environments, cleaning (maintenance) is
not required until after approximately 2,500 hours of
operation, thus reducing maintenance work.
•
• •
• For optimum comfort, it is recommended to clean the air
filter every 1-1/2 months.
2.5.2. Maintenance is possible from
underneath the unit.
•
• •
• If the bottom panel is detached, the drain pan can then be
removed and installed from underneath the unit, and
inspection and servicing of component such as the control
panel also becomes easier.
2.6. Auto fan mode (indoor unit)
•
• •
• Auto fan mode is added besides high, medium and low. It
automatically adjusts the fan speed according to the indoor
unit’s temperature.
2.7. Hot start system (heat pump
models)
2.8. Automatic changeover
function (heat pump models)
•
• •
• The unit automatically switches between cooling and
heating in accordance with operating load in order to
maintain a comfortable indoor temperature.
2.9. Greatly improved workability
increases system renewal
capability
•
• •
•
Pipes that are one size larger can also be connected for
renewal.
−
− −
− If renewing the system, existing refrigerant pipes can be
utilized so that only the indoor and outdoor units need to
be replaced.
−
− −
− For example, liquid and gas pipes from 10 years ago
can be connected to current pipes with the same size or
one size larger. Effective utilization of materials reduces
working time and trouble. (Adaptor sockets are not
supplied.)
