IF SAFETY PRECAUTIONS
FOR INSTALLING AND
RELOCATING THE UNIT:
WARNINGS!
1. When installing or relocating the unit, be sure to
keep the refrigerant circuit free from air and other
substances other than the specified refrigerant.
Presence of air or other foreign substance in the
refrigerant lines will cause the system pressure to
rise and could cause the compressor to rupture –
causing injury.
2. When installing or moving the unit, DO NOT charge
with refrigerant other than the specified type listed
on the nameplate of the unit.
This will cause abnormal operation, improper actions
and mechanical malfunction and may result in
serious injury.
3. Refrigerant recovery during relocation or repair:
Ensure unit is running in cooling mode. Fully close
valve at high pressure side (liquid valve). After 30
seconds, fully close valve at low pressure side (gas
valve). Immediately stop the unit and disconnect
power. Total time for refrigerant recovery should not
exceed 1 minute.
If refrigerant recovery takes too much time, air may
be sucked in causing the pressure to rise and the
compressor to rupture which can lead to severe
injury or death.
4. During refrigerant recovery, make sure the liquid and
gas lines are fully closed and power is disconnected
before detaching the connection pipe.
If the compressor starts running while stop valve is
open and connection pipe is not affixed, air will be
sucked in causing pressure to rise and potentially
causing compressor rupture which may lead to
severe injury or death.
5. When installing the unit, make sure the connection
pipe is securely connected before the compressor
starts running.
If the compressor starts running while stop valve is
open and connection pipe is not affixed, air will be
sucked in causing pressure to rise and potentially
causing compressor rupture which may lead to
severe injury or death.
6. DO NOT install the unit in an area exposed to (or
potentially exposed to) corrosive or flammable gas
leaks.
Leaking gas near the unit may cause fire or
explosion leading to property damage, severe injury
or death.
7. DO NOT use extension cords for electrical
connections. If the electrical wire in not long
enough, contact a local service authorized center to
install the proper length wiring.
Poor connections may lead to electrical shock or fire.
8. Use manufacturer specific wires for connections
between indoor and outdoor units. Firmly clamp
wires between indoor and outdoor units. Ensure
terminals receive NO external stress.
Electric wires with insufficient capacity, improper
connection points, and/or improperly secure
terminals may cause electric shock or fire.
