1. REDI-CHARGED REFRIGERANT SYSTEM
The industry’s first redi-charged refrigerant system.
There is no need to adjust the amount of refrigerant to match the piping length
on- site unless lines exceed 100ft.
You will see a major reduction in installation time and labor costs.
2. HIGH RELIABILITY AND EASY SERVICING
In addition to the self-diagnostic function, units are also equipped with a 3-minute time delay mechanism (cooling), an auto
restart function, an emergency operation function, a test run switch, etc., to assure high reliability and easy servicing.
3. FOUR-WAY PIPING ACCESS MAKES
INSTALLATION LAYOUT EASY
Piping on the outdoor unit may be connected from either of
four directions: front, rear, side or beneath the base.
This easy-access design makes it possible to install a
number of units in a compact arrangement at a single site.
The outdoor unit allows for unheard-of flexibility in
determining a piping layout, thus greatly simplifying
installation.
4. FRONT-ACCESS FACILITATES
MAINTENANCE
The outdoor unit has been designed with a front-access
service panel that allows easy access to all maintenance
point, regardless of the installation layout. What’s more, this
front panel may be removed by loosening only two screws.
It all adds up to greatly simplified maintenance work.
