Cooling / heating Correction Factors For the Art Cool Premier system, calculate the equivalent length of the liquid line from the outdoor unit to the indoor unit. Also, determine the elevation difference of the indoor unit above or below the outdoor unit. Find corresponding cooling or heating capacity correction factors as shown in Figure 5 and Figure 6.

building VEntilation dESign guidE Method 2: unconditioned outdoor air (non-ducted, natural Ventilation) natural ventilation devices, such as operable windows or louvers may be used to ventilate the building when local code permits. The open area of a window or the free area of a louver must meet the minimum percentage of the net occupied floor area. Advantages disadvantages • occupants control the volume of the ventilation air manually.
ConSidErationS Single Zone Art Cool Premier Selecting the best location Select a location for installing the outdoor unit that will meet the following conditions: • Where the unit will not be subjected to direct thermal radiation from other heat sources.
Wind restraints The strength of the Single Zone Art Cool Premier frame is adequate to be used with field-provided wind restraint tie-downs. The overall tie- down configuration must be approved by a local professional engineer. Always refer to local code when designing a wind restraint system.

Components such as oil traps, solenoid valves, filter-dryers, sight glasses, tee fittings, and other after-market accessories are not permitted on the refrigerant piping system between the outdoor unit and the indoor unit. Art Cool Premier Wall Mount air-source systems are provided with redundant systems that assure oil is properly returned to the compressor.
Sleeves at penetrations LG requires that all pipe penetrations through walls, floors, and pipes buried underground be properly insulated and routed through an appropriate wall sleeve of sufficient size to prevent compression of refrigerant pipe insulation and free movement of the pipe within the sleeve.
