Figure 7: Loop Connection (Indoor Compressor Section)

		NOTICE! Cabinet opening around loop piping (outdoor
		compressor section) must be sealed to prevent entry of
		rodents that could potentially damage unit wiring by chewing
		on the insulation.
		NOTICE! Outdoor compressor section may not be tilted
		more than 5 degrees from level. Damage to the compressor
		or stress on the loop piping could result if unit is tilted. A
		concrete pad, anchor posts and/or soil compaction may be
		required to avoid tilting as ground settles.
