Precautions for Selecting the Location 1) Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified. 2) Choose a location where the hot air discharged from the unit or the operation noise, will not cause a nuisance to the neighbors of the user.
Indoor/outdoor Unit Installation Drawings For installation of the indoor units, refer to the installation manual which was provided with the units. (The diagram shows a wall-mounted indoor unit.) Caution 1) Do not connect the embedded connect piping and the outdoor unit when only carrying out piping work without connecting the indoor unit in order to add another indoor unit later.
Outdoor Unit Installation Guideline • Where a wall or other obstacle is in the path of outdoor unit intake or exhaust airflow, follow the installation guidelines below. • For any of the below installation patterns, the wall height on the exhaust side should be 1200 mm or less. Wall facing one side Walls facing two sides More than 50...
Refrigerant piping work Installing Outdoor Unit 1) When installing the outdoor unit, refer to “Precautions for Selecting the Location” and the “Indoor/outdoor Unit Installation Drawings.” 2) If drain work is necessary, follow the procedures below. Drain Work 1) Use drain plug for drainage. 2) If the drain port is covered by a mounting base or floor surface, place Drain-water hole additional foot bases of at least 30 mm in height under the outdoor...
Refrigerant piping work Purging Air and Checking Gas Leakage Warning 1) Do not mix any substance other than the specified refrigerant (R410A) into the refrigeration cycle. 2) Refrigerant gas leaks during air purging, ventilate the room as soon as possible. 3) To prevent air pollution, a vacuum pump should be used for air purging wherever possible.
Charging with Refrigerant • If the total length of piping for all rooms exceeds 20m, additionally charge with (R410A) 20 g of refrigerant for each addi- tional meter of piping. When extra refrigerant is added, write down the total length of the piping and the amount added on the nameplate for recording how much refrigerant has been added on the back of the service lid on the outdoor unit.
