CAUTION 1. Connect the (evaporator) indoor unit first then the outdoor unit and bend and arrange the pipe carefully. 2. Ensure there is no slack in the drain hose. 3. After removing drain hose, be sure not to forget mounting drain cap. 4. Be sure to fix the drain hose with tape to the bottom of piping. 5. Prevent drain water from freezing in low temperature environments. When installing evaporator (indoor) unit’s drain hose outdoors, necessary mea- sures for frost protection should be

CONDENSOR INSTALLATION (OUTDOOR) 1) Condensor (Outdoor) Unit Installation Precaution Install the outdoor unit on a rigid base to prevent increasing noise level and vibration. Determine the air outlet direction where the discharged air is not blocked. In the case that the installation place is exposed to strong wind place the unit lengthwise along the wall or use dust or shield plates. If need suspended installation, the installation bracket should accord with technique requirement in th
