Ceiling Mount Cassette Systems are designed for high performance, easy installation and service. Each system
consists of one or several indoor units and one outdoor unit, which are connected by one set or several sets of
interconnection refrigerant pipes and electric wires.
As shown in the following sample picture, air is drawn through the center grilles/filters and then discharged at 4
vents in 4/8 directions. In cooling mode, air passing through coil is cooled; in heating mode, air passing through
coil is heated.
INTRODUCTION
Sample Split System-Indoor and Outdoor Units
(For Continuous Engineering Improvement and Various Marketing Needs and Actual Part Availability
Reason, Unit Appearance Subject to Change or Update Continuously without Prior Notice)
The electrical and thermal power for the whole system comes from the outdoor unit. In YMGI SHCR or TTWC
series of side discharge outdoor condensing unit(s), electrical and thermal components such as compressors and
motors and heat exchange coils and others, are incorporated into the cabinet in an optimized order. These
condensing units can be either hung on the wall or installed on the ground. Once stacking or bracket kit is used,
some outdoor units can be stacked 2 or 3 units high, upon unit size and applications. Air is discharged
horizontally, quietly and smoothly. These units are a perfect fit in locations where installation and applications of
general up-flow condensing units are limited, such as apartments, condos, lofts, multi-families and high-rise
buildings and others.
Indoor unit(s) delivers the thermal and acoustical comfort to the rooms. In cooling mode, air passing through coil
is cooled; in heating mode, air passing through coil is heated. Air is filtered or treated by the built-in mechanism
(washable or enzyme equipped or electrostatic powered filter, varies from model to model), before being
delivered into the room, with more than enough comfort and care, at a wide angle (swing or not, varies from
model to model).

zone unit SHALL NOT be used to take care of the cooling or heating load of more than one-story room. Several
single-zone ductless systems or multiple-zone ductless systems shall be used in this regard.
These units are designed for applications at:
* Residential * Light commercial
* Commercial * Institutional
