Safety Warnings
4
• Use copper wires only for power supply
• Risk of electric shock can cause injury or death. Disconnect all electric power supplies
before servicing or installation.
• Do not use excessive torque on flare nuts during connection of the refrigeration tubes, or
service valve on discharge line may be damaged.
• Do not put indoor unit in a location where it could get wet.
• Electrical installation must be done by a qualified technician according to instruction
manual and in accordance with local electrical standards
• Certified power supply conductors must be used.
INSTALLATION KITS
Installation kits are available for all NCP Mini-Split systems. These kits contain a 20’ line
set appropriate for each model, connecting wires, PVC tape, drainage hose, and wall
sleeve(s).
Contact your local dealer for availability.

Select Installation Locations

Indoor Unit:
• The air intake and outlet should not be obstructed.
• The wall the unit is mounted on should allow for a clear hole for the condensation drain
line and the refrigeration lines.
• The wall the unit is mounted on should be strong enough to bear the weight and vibration
of the unit.
• Allow for proper clearances around the unit - see installation dimension diagram (page 3).
• Location should allow easy access for maintenance and removal of air filter.
• Position unit and remote control at least 3 feet from electric appliances such as televi-
sions, radios, etc.
• Keep unit and remote out of direct sunlight and/or flourscent lighting and away from any
excessive heat source, steam, or flammable materials.
Outdoor Unit:
• Allow sufficient ventilation around the unit - see installation dimension diagram (page 3).
• The air intake and outlet should not be obstructed.
• Position unit so that noise and outlet airflow will not inconvenience neightbors.
• Position unit on a solid foundation.
• Location should be able to withstand the full weight and vibration of the unit.
Both Indoor and Outdoor Units:
Installation of either unit in the following locations may cause malfunction. Locations exposed to:
• machine oil
• flammable or corrosive gases
• high-frequency waves (i.e. from radio equipment, medical equipment, etc.)

Indoor Unit Installation
1. Install the Rear Panel (mounting plate)
• Always mount rear panel horizontally.
• Hold the rear panel on the wall where you want the unit to be located and ensure that it is level
using a plumb line or level. Once leveled, mark the screw locations on the wall.
• Fasten the rear panel to the wall at the location marked using the screws supplied with the unit.
• Ensure that the panel has been mounted firmly to withstand the weight of the unit, with the weight
being evenly shared by each screw.
2. Install the Piping Hole
• Select location for piping hole - either left-positioned or right-positioned (see installation dimension
diagram on page 3).
• Make piping hole in the wall approximately 2.5 inches in diameter at a slight downward slant (this
ensures proper drainage).
• Insert a piping-hole sleeve in the hole (i.e. PVC pipe) to prevent the connection piping and wiring
from being damaged
3. Install Drainage Hose Extension (optional)
• Drainage hose extension is included with unit, for use if attached drainage line is not long enough
for your application.
• Please note that the extension can be installed after existing drainage pipe is fed through wall later
in the installation process, if it is determined later that it is necessary.
• Do not wrench or bend drainage hose or extension.
CAUTION! - Failure to connect wiring as indicated below will result in damage to
the unit and/or personal injury. Mis-wiring will also void warranty. DO NOT inter-
change any wiring connections!
4. Wire the Unit.
• Note: All electrical wiring must be done by a qualified technician in accordance with local electrical
standards
• An independent circuit breaker should be used.

5. Prepare Refrigeration Lines
• Refrigeration lines and wiring can be routed from the indoor unit to the outdoor unit sev-
eral different ways, using the cut-out access pieces on the back of the unit.
• Bend the refrigeration lines carefully to the position needed to align with the drilled piping
hole.

Note: Grounding between the indoor unit and the outdoor unit is accomplished through the coolant
line set.

Indoor Unit Installation (cont.)
6. Hang Indoor Unit
• Bundle the refrigeration lines, drainage hose, and
wiring conduit attached to the indoor unit and
wrap them securely for enough length to extend
through the piping hole to the exterior of the
building. (Note: leave remainder unwrapped to
allow for remaining steps in installation of the
outdoor unit and connecting the indoor unit to the
outdoor unit.)
• Carefully push bundled lines through the piping
hole.
• Hang the unit on the wall by hooking the mounting
slots of the unit over the upper tabs of the rear
panel.
• Check to make sure the unit is properly secured --
it should feel firmly attached to the wall, and you
should not be able to slide it to the right or left.

Outdoor Unit Installation
1. Connect Refrigeration Lines to Bundled Lines from Indoor Unit
• Use standard A/C practices to attach the connection pipes to the proper pipes of the
bundled lines coming through the wall from the indoor unit.
• Tighten the flare nut of the connection pipes using a spanner
and torque wrench. (see diagram)
• Note: Do not over-tighten flare nuts, or the connection may be
damaged.
2. Insulate/Bundle Refrigeration Lines and Wiring
• Individually insulate all refrigeration lines and condensation drainage hose to ensure that
they do not sweat. This will help to maintain the unit at its proper capacities.
• Once all lines have been properly insulated, bundle the refrigeration lines with the wiring
conduit and wrap securely to complete the run to the outdoor unit.
• Note: The condensation drainage hose should be left free of the bundled lines in order to
drain properly.
3. Install Outdoor Condensation Drainage Hose (Heat Pump Models Only)
• When the heat pump unit is heating or defrosting, wastewater forms in
the outdoor unit. This can be drained off using the outdoor drain elbow
and hose provided.
• Insert the drain elbow into the hole on the base plate as shown.
• Joint the drain hose to the elbow and turn so that the water
drains in the desired location.
