There is risk of product damage or failure, or
unintended operation.
n Take care to ensure that nobody could step on or fall
onto the outdoor unit.
This could result in personal injury and product
damage.
Ø CAUTION
n Always check for gas (refrigerant) leakage after
installation or repair of product.
Low refrigerant levels may cause failure of product.
n Install the drain hose to ensure that water is drained
away properly.
A bad connection may cause water leakage.
