d) In case that upper side obstacles exist (serial units)
0 < L ≤ 1/2 H A ≥ 500
1/2 H < L ≤ H A ≥ 1000
0 < L ≤ 1/2 A ≥ 500
1/2 H < L ≤ H A ≥ 1000
g) horizontal (multiple units)
0 < L ≤ 1/2 H A ≥ 100
1/2 H < L ≤ H A ≥ 200
≥ 1000
Do not stack more than two units in height. - Close gap (*) to avoid recirculating discharge air flow.
