Outdoor Unit (Compressor)
• Set the unit on a stable, level surface.
• Use adjustment risers to prevent debris and snow
build-up and allow better drainage.
• Secure outdoor units to the pad, risers and/or
surface using bolts and/or adhesives.
Line Set Insulation and Protection
• Insulation must cover entire line set length to
avoid condensation and decreased efficiency.
• Once insulated, protect the outdoor portion of
the line set with Line Hide to avoid premature
insulation damage.
• Add UV tape as needed on areas without Line
Hide to ensure entire length is protected.
Refrigerant Charge
• Adjust refrigerant charge ONLY IF NECESSARY;
most installations do not require adjustments.
• Gauges are not needed to verify refrigerant levels.
Only if adjustments are necessary, be sure to use
a scale when adding/removing refrigerant.
Condensate Drain
• Must slope downhill and can be routed with line
set and run to a suitable termination point, away
from crawl spaces and walkways.
Cold Climate Recommendations
• Use a pan heater to avoid defrost discharge
freezing inside the compressor.
• Increase clearance under the outdoor unit to
promote easy drainage and reduce snow and
ice buildup.
• Consider wall-mount brackets to maximize
outdoor unit clearance.
Tools
• Ratchet Flaring Tool
• Programmable Refrigerant Charging Scale
• Torque Wrench
• R410A Gauge and Hose Set
INSTALLATION BEST PRACTICES
Installation Tips for Maximum Efficiency—Indoors
• For homes with electric furnaces, consider shutting off the furnace at the breaker or set back
the furnace thermostat so that it does not compete with the Mitsubishi Electric system.
• For homes with zonal electric heat, consider shutting off the heaters at the breaker or set back
the zonal heater thermostats so they do not compete with the Mitsubishi Electric system.
• For temperature set back, set programmable thermostat to HEAT with the fan in ON position
for air distribution and setting the temperature 4° F below the Mitsubishi Electric system.
