SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service,
maintenance, or use can cause explosion, fire, electrical shock,
or other conditions which may cause death, personal injury or
property damage. The qualified installer or agency must use
factory-authorized kits or accessories when modifying this
product.
Follow all safety codes. Wear safety glasses, protective
clothing, and work gloves. Use quenching cloth for brazing
operations. Have fire extinguisher available. Read these
instructions thoroughly and follow all warnings or cautions
included in literature and attached to the unit. Consult local
building codes and the current editions of the National
Electrical Code (NEC) ANSI/NFPA (American National
Standards Institute/National Fire Protection Association) 70. In
Canada, refer to the current editions of the Canadian Electrical
Code CSA (Canadian Standards Association) C22.1.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Medium Static Duct Indoor Unit for
Variable Refrigerant Flow (VRF) Systems
Understand the signal words - DANGER, WARNING,
and CAUTION. DANGER identifies the most serious hazards
which will result in severe personal injury or death.
WARNING signifies hazards that could result in personal
injury or death. CAUTION is used to identify unsafe practices,
which would result in minor personal injury or product and
property damage.
Recognize safety information. This is the safety-alert
symbol ( ). When this symbol is displayed on the unit and in
instructions or manuals, be alert to the potential for personal
injury. Installing, starting up, and servicing equipment can be
hazardous due to system pressure, electrical components, and
equipment location.
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all
disconnect locations to alert others not to restore power
until work is completed.
When installing the equipment in a small space, provide
adequate measures to avoid refrigerant concentration
exceeding safety limits due to refrigerant leak. In case of
refrigerant leak during installation, ventilate the space
immediately. Failure to follow this procedure may lead to
personal injury.
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and
goggles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from
system using high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen
and work area should be well ventilated. Refrigerant
in contact with an open flame produces toxic gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when
necessary. Oil can ignite when exposed to torch
flame.
Failure to follow these procedures may result in personal
injury or death.
