WARNING
Important!
Please Read Before Starting
This air conditioning system meets strict safety and operating
standards. As the installer or service person, it is an
important part of your job to install or service the system so it
operates safely and efficiently.
For safe installation and trouble-free operation, you must:
Carefully read this instruction booklet before beginning.
Follow each installation or repair step exactly as shown.
Observe all local, state, and national electrical codes.
Pay close attention to all warning and caution notices given
in this manual.
If Necessary, Get Help
These instructions are all you need for most installation
sites and maintenance conditions. If you require help for
a special problem, contact our sales/service outlet or
your certified dealer for additional instructions.
In Case of Improper Installation
The manufacturer shall in no way be responsible for
improper installation or maintenance service, including
failure to follow the instructions in this document.
Do not supply power to the unit until all wiring and tubing
are completed or reconnected and checked.
Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and
inadequate grounding can cause accidental injury or death.
Ground the unit following local electrical codes.
Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.
Install a protective leakage breaker depending on the
installation location (especially a damp or humid
location). If a leakage breaker is not installed, electric
shock can occur.
When Transporting
Be careful when picking up and moving the indoor and
outdoor units. Get a partner to help, and bend your knees
when lifting to reduce strain on your back. Sharp edges or thin
aluminum fins on the air conditioner can cut your fingers.
When Installing
In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the unit’s
weight. It may be necessary to construct a strong wood or
metal frame to provide added support.
In a Room
Properly insulate any tubing run inside a room to prevent
"sweating" that can cause dripping and water damage to walls
and floors.
In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a
solid, level foundation for the outdoor unit. This prevents water
damage and abnormal vibration.
In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal
frame. Provide a suitable air baffle.
In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than
drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
Use the flare method for connecting tubing.
Apply refrigerant lubricant to the matching surfaces of the
flare and union tubes before connecting them, then tighten
the nut with a torque wrench for a leak-free connection.
Check carefully for leaks before starting the test run.
When Servicing
Tu rn the power off at the main power box (mains) before
opening the unit to check or repair electrical parts and
wiring.
Keep your fingers and clothing away from any moving parts.
Clean up the site after you finish, remembering to check
that no metal scraps or bits of wiring have been left inside
the unit being serviced.
Others
Ventilate any enclosed areas when installing or testing the
refrigeration system. Escaped refrigerant gas, on contact
with fire or heat, can produce dangerously toxic gas.
Confirm upon completing installation that no refrigerant gas
is leaking. If escaped gas comes in contact with a stove,
gas water heater, electric room heater or other heat source,
it can produce dangerously toxic gas.

4. REFRIGERANT FLOW DIAGRAM
4-1. Refrigerant Flow Diagram
Outdoor Unit CMH1972
Insulation of Refrigerant Tubing
Because capillary tubing is used in the outdoor unit, both the
wide and narrow tubes of this air conditioner become cold. To
prevent heat loss and wet floors due to dripping of
condensation, both tubes must be well insulated with a
proper insulation material. The thickness of the insulation
should be a min.5/16"(8 mm).
After a tube has been insulated,
never try to bend it into a narrow
curve because it can cause the tube
to break or crack.
