IMPORTANT NOTES
These precautions are essential and must be strictly observed.
DO NOT pull on the power cord or refrigeration lines.
Install them in a secured position. A line set plastic
cover is recommended.
DO NOT install the unit in places where there is
exposure to flammable materials or gas leakage.
DO NOT use wire or circuit breakers that do not meet
electrical safety standards. Several circuits cannot
be connected to one breaker.
DO NOT wire or open the unit while it is running.
Make sure to shut off all circuits prior to inspecting or
servicing the unit.
DO NOT install unit in a damp laundry room or near
flammable gas. All units must be protected by
certified electrical circuit breakers and in accordance
with all safety codes.
DO NOT use the unit in cool or dry mode for
prolonged periods where humidity is higher than 80%.
SAFETY WARNINGS
READ THESE SAFETY WARNINGS COMPLETELY PRIOR TO ANY USE.
DO NOT install the indoor unit close to cooking
surfaces or ventilation systems. Poor placement
could inhibit peak performance.
DO NOT blow cold air directly towards people for
extended periods. It may get you a bad cold.
DO NOT use chemical solvents, flammable
insecticides, or abrasive materials. Clean the unit
only with a soft dry cloth or rag.
DO NOT continue to operate the unit if there is any
abnormal odor, burning, scorching, or smoke. Stop
and disconnect the unit immediately.
DO NOT use the system for anything other than what
it was designed for or any non-HVAC purposes. Do
not store near food, paint, or other chemicals.
DO NOT operate the unit for prolonged periods
without refreshing ambient air. Opening a door or
window periodically will suffice.

DO NOT draw on the power cord or refrigeration
lines. Install them in secured positions. Plastic
cover of line set is recommended.
DO NOT blow the cold air directly towards people
for prolonged period. Otherwise, people may get
cold.
DO NOT use smaller than enough wires. Do not
put several circuits to one breaker. Don't use
smaller than enough circuit breakers. Otherwise
power failure or fire may be caused.
DO NOT wire or open unit while unit is running.
Sparks or fire may occur. It may cause a shock to
people.
Mini Split Wall Mount 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 multiple
sets of interconnection refrigerant pipes and electric wires.
As shown in the following sample picture of outdoor unit, air is drawn through the coil from the rear side and then
discharged from the front side. In cooling mode, air passing through coil is heated; in heating mode, air passing
through coil is cooled.

Outdoor unit(s) provides the electrical and thermal power for the whole system. Electrical and thermal
components such as compressors and motors and heat exchange coils and others, are incorporated into the
cabinet in an optimized order. They 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 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 named or unnamed.
Indoor unit(s) delivers the thermal and acoustical comfort to the rooms. Air is drawn through the coil from the
front or topside and then discharged from the bottom. 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).

NOTES: Since ductless system is not designed to incorporate or use with ducted return or discharge tunnels, one
single-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 proper in this regard.
These units are designed for applications at:
* Residential
* Light commercial
* Commercial
* Hospital
* Institutional
* Industrial
