Outdoor Unit Installation
• Install the outdoor unit on a rigid base such a
concrete slab to prevent increasing noise level and
vibration.
• Use a raised concrete pad or concrete blocks to
provide a solid, level surface. Securely anchor the
unit down with bolts.
• In a snowy area, slab should be higher than drifting
snow.
• See outdoor installation location information on page.
4 for more details and acquired clearances.
Anchoring outdoor unit
Anchor the outdoor unit to the concrete slab with lag
bolts or similiar size, may vary by model.
NOTE: Lag bolts are field provided and do not come

Condensate Drainage

• Condensate and defrosted water, created by the
unit operating in heat mode, should be routed
and drained away from the unit.
• Fit the seal onto the drain elbow, then insert the
drain elbow into the hole on the base pan of the
outdoor unit, rotate it 90° to secure into place.

hose to the hose barb end of the elbow.
