WARNING:HAZARDOUSVOLTAGE

Failure to follow this warning could result in property

damage, severe personal injury, or death.

Disconnect all electric power, Including remote disconnects

before servicing. Follow proper lockout/tagout procedures

to ensure the power cannot be inadvertently energized.

WARNING:REFRIGERANTOIL

Any attempt to repair a central air conditioning product may

result in property damage, severe personal injury, or death.

These units use R-410A refrigerant which operates at

50 to 70% higher pressures than R-22. Use only R-410A

approved service equipment. Refrigerant cylinders are

painted a “Rose” color to indicate the type of refrigerant

and may contain a “dip” tube to allow for charging of liquid

refrigerant into the system. All R-410A systems with variable

speed compressors use a POE oil (VG74 or equivalent )

that readily absorbs moisture from the atmosphere. To

limit this ‘hygroscopic“ action, the system should remain

sealed whenever possible. If a system has been open to

the atmosphere for more than 4 hours, the compressor oil

must be replaced. Never break a vacuum with air and always

change the driers when opening the system for component

replacement.

WARNING:HOTSURFACE

May cause minor to severe burning. Failure to follow this

Caution could result in property damage or personal injury.

Do not touch top of compressor.

CAUTION:CONTAINS REFRIGERANT

Failure to follow proper procedures can result in personal

illness or injury or severe equipment damage.System

contains oil and refrigerant under high pressure. Recover

refrigerant to relieve pressure before opening system.

This product can expose you to chemicals including Lead

and Lead components, which are known to the State

of California to cause cancer and birth defects or other

reproductive harm. For more information go to www.

P65Warnings.ca.gov.

CAUTION:GROUNDINGREQUIRED

Failure to inspect or use proper service tools may result

in equipment damage or personal injury. Reconnect all

grounding devices. All parts of this product that are capable

of conducting electrical current are grounded. If grounding

wires, screws, straps, clips, nuts, or washers used to

complete a path to ground are removed for service, they

must be returned to their original position and properly

fastened.

Cold climate considerations (heat pump only)

Precautions must be taken for units being installed in areas where

snow accumulation and prolonged below-freezing temperatures occur.

Units should be elevated 3-12 inches above the pad or rooftop,

depending on local weather. This additional height will allow drainage of

snow and ice melted during defrost cycle prior to its refreezing. Ensure

that drain holes in unit base pan are not obstructed, which could prevent

the drainage of defrost water (Fig. 5).

If possible, avoid locations that are prone to snow drifts. If not possible,

a snow drift barrier should be installed around the unit to prevent a build-

up of snow on the sides of the unit.
