Mounting / Anchoring the Outdoor Unit
INSTALLATION
• Remove the wood pallet from the bottom of the outdoor unit base pan before brazing.
A fire may occur if the pallet is not removed.
• Remove the wood pallet from the bottom of the outdoor unit base pan before at-
taching the anchor bolt. If the pallet is not removed, the outdoor unit may become
unstable and heat exchanger may freeze, resulting in improper operation.
• Outdoor unit supports must be ≥3-15/16 inches wide and ≥7-7/8 inches high.
• 3/8-inch or 5/16-inch anchor bolts must be inserted at least 2-15/16 inches deep into the supports.
Remove wood pallet before
installing unit.

Figure 3: Support Options.
• When building a base support for the outdoor unit, ensure that the floor surface / location has enough strength to support the weight
of the unit, enough space for the pipes and wiring, and sufficient slope for proper drainage between the units, the condensate drain
connection, and the floor drain.
• Install the outdoor unit to protect against extremely high winds and earthquakes. Any deficiency in installation may cause unit to fall,
resulting in physical injury or death.
Securely attach the outdoor unit to a concrete pad, base rails, or other mounting platform that is anchored to the building structure. Avoid
placing the unit in a low lying area where water may accumulate. Refer to dimensional drawings in the “Product Data” section on pages 16 to
21 and pages 48 to 53, and follow the applicable local and state codes for clearances, mounting, anchor, and vibration attenuation
requirements.
