•
For SD compressor units (which have potable domestic water connections) where the
surrounding air temperature remains above 40°F.
•
Where suggested clearance is 3 feet on both sides, top and front, for access. However, local
codes and applicable regulations take precedence. Clearance from back panel to wall and
minimum side clearance should be at least one foot. See Figure 4 for details.
•
Where the total length of refrigerant line sets (from manifolds to compressor and from
compressor to air handler) do not exceed 125 feet, as shown in Figure 2.
•
Where the compressor unit is no more than 20 feet higher than the earth loop manifolds.
Compressor unit may be located lower than the earth loop manifolds. See Figure 2.
•
For SCW, HCW and HWW compressor units providing radiant panel hydronic hot water, where
the hydronic primary circuit is adequately protected from freezing by controlling the surrounding
lowest air temperature to 40
o
F minimum and/or providing an industry approved anti-freeze and
water mixture for the surrounding lowest air temperature.
