Installation; Qualified Oils & Refrigerant - Emerson KHZ506 User Manual

Installation

The condensing unit should be located in such a place to prevent any dirt, plastic bag, leaves or papers from
covering the condenser and its fins. The unit must be installed without restricting the airflow. A clogged condenser
will increase the condensing temperature, thus reduce the cooling capacity, and lead to a high-pressure switch
tripping. Clean the condenser fins on a regular basis.
