Shipping and Packing List
General
Check the components for shipping damage. If you

-
rier. Package 1 of 1 contains the following:
1 - Assembled Mini-VRF heat pump outdoor unit
1 - Outdoor unit installation instruction
The Mini-VRF heat pump outdoor units are matched
with up to nine indoor units to create a VRF (variable
refrigerant flow) system that uses R-410A refrigerant.
Refer to the Product Specification bulletin (EHB) for
the proper use of these heat pumps with matching
indoor units, header pipes, branch pipes, line sets
and controls.
These instructions are intended as a general guide
and do not supersede local or national codes in any
way. Authorities having jurisdiction should be con-
sulted before installation.
WARNING
Improper installation, adjustment, alteration, ser-
vice or maintenance can cause property damage,
personal injury or loss of life.
Installation and service must be performed by a li-
censed professional HVAC installer, service agency
or the gas supplier.
Failure to follow safety warnings and these instruc-
tions exactly could result in property damage, dan-
gerous operation, serious injury, or death.
Any additions, changes, or conversions required in
order for the appliance to satisfactorily meet the ap-
plication needs must be made by a licensed profes-
sional HVAC installer (or equivalent) using factory-
specified parts.
Do not use this system if any part has been under
water. A flood-damaged appliance is extremely dan-
gerous. Immediately call a licensed professional
HVAC service technician (or equivalent) to inspect
the system and to replace all controls and electrical
parts that have been wet, or to replace the system, if
deemed necessary.
CAUTION
As with any mechanical equipment, contact with sharp
sheet metal edges can result in personal injury. Take
care while handling this equipment and wear gloves and
protective clothing.
IMPORTANT
The Clean Air Act of 1990 bans the intentional venting
of refrigerant (CFC’s and HCFC’s) as of July 1, 1992.
Approved methods of recovery, recycling or reclaiming
must be followed. Fines and/or incarceration may be
levied for non-compliance.
CAUTION
To ensure proper system performance and reliability,
Lennox does not recommend operation of VRF sys-
tems during any phase of construction. Construction
debris, low temperatures, harmful vapors, and opera
-
tion of the unit with misplaced filters can damage the
units. Failure to follow these guidelines will result in the
warranty being voided.
