37MGHAQ: Installation Instructions
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

A. INSTALLATION INSTRUCTION
• A location which is convenient to installation and not exposed to
strong winds.
• A location which can bear the weight of the outdoor unit and where
the outdoor unit can be mounted in a level position.
• A location which provides appropriate clearances (See Fig. 7 — on
page 16).
• Allow sufficient space for airflow and service of the unit. See Fig. 7
— on page 16 for the required minimum distances between the unit or
walls.
NOTE: DO NOT install the indoor or outdoor units in a location
with special environmental conditions. For those
applications, contact your Ductless representative.
NOTE: Basepan built-in with multiple holes for proper draining
during defrost. For applications where it is required to seal
these holes, and re-direct the condensate drain, rubber
plugs are available through RCD.
Table 9 — Base Pan Rubber Plugs
IMPORTANT: Both refrigerant lines must be insulated
separately. Use refrigeration grade tubing ONLY. No other
type of tubing may be used. Use of other types of tubing will
void the manufacturer's warranty.
• The minimum refrigerant line length between the indoor and outdoor
unit is 10 ft. (3m).
• When paired with Ductless indoor units, size the line sets based on the
connection size of the indoor unit unless specified.
• When paired with conventional or multi-family fan coils, size the line
sets based on the liquid and gas connection size of the outdoor unit; a
field supplied reducer may be required.
• All outdoor units have an electronic expansion valve to manage the
refrigerant flow of the fan coil connected.
• Do not open the service valves or remove the protective caps from the
tubing ends until all connections are made.
• Bend the tubing with bending tools to avoid kinks and flat spots.
• Keep the tubing free of dirt, sand, moisture, and other contaminants to
avoid damaging the refrigerant system.
• Avoid sags in the suction line to prevent the formation of oil traps.
• Insulate each tube with a minimum 3/8-in. (10 mm) wall thermal pipe
insulation. Inserting the tubing into the insulation before making the
connections saves time and improves installation quality.

PRODUCT INSTALLATION
Installation must be performed by an authorized dealer or specialist.
A defective installation can cause water leakage, electrical shock, or
fire.
The installation must be performed according to the installation
instructions. Improper installation can cause water leakage,
electrical shock, or fire. (In North America, installation must be
performed in accordance with the requirements of NEC or CEC by
authorized personnel only.)
Contact an authorized service technician for repair or maintenance
of this unit. This appliance must be installed in accordance with
local codes.
Only use the included accessories, parts, and specified parts for
installation. Using non-standard parts can cause water leakage,
electrical shock, fire, or unit failure.
To prevent exposure to wind, install the outdoor unit with its air
inlet side facing the wall
Install drainage piping according to the instructions in this manual.
Improper drainage may cause water damage to your home and
property.
DO NOT install the unit in a location that may be exposed to
combustible gas leaks. If combustible gas accumulates around the
unit, it may cause a fire.
DO NOT turn on the power until all work has been completed.
When moving or relocating the system, consult experienced service
technicians for the disconnection and re-installation of the unit.
WA R N I N G
All field piping must be completed by a licensed technician and
must comply with the local and national regulations.
When the system is installed in a small room, measures must be
taken to prevent the refrigerant concentration in the room from
exceeding the safety limit in the event of refrigerant leakage. If the
refrigerant leaks and its concentration exceeds its proper limit,
hazards due to lack of oxygen may result.
When installing the refrigeration system, ensure that air, dust,
moisture or foreign substances do not enter the refrigerant circuit.
Contamination in the system may cause poor operating capacity,
high pressure in the refrigeration cycle, explosion or injury.
Ventilate the area immediately if there is refrigerant leakage
during the installation.
Leaked refrigerant gas is hazardous. Ensure there is no refrigerant
leakage after completing the installation work.
WAR N I N G
DO NOT install the connecting pipe until both the indoor and
outdoor units have been installed.
Insulate both the gas and liquid piping to prevent condensation.
