8 Preparing for Installation Accessories In addition to product literature, the following accessories are supplied with this unit. The type and quantity may differ, depending on the model. Flexible hose Template Insulation A Insulation B Insulation C clamp Flexible hose Cable tie Conduit bracket Note: The required panel is not included with the indoor unit. It must be ordered separately (Model #TVEPANPC4 NUSET). Location Considerations When deciding on a location for the indoor unit, the following factors must be considered: The air inlet and outlet must be unobstructed. The wall or ceiling must support the weight of the unit. The wall or ceiling must not be subject to vibration. Pre-plan for easy and short routing of the refrigerant tubing and wiring to the outdoor unit. The air must circulate freely in the area to be cooled/heated. Sufficient clearance must be maintained around the unit.

9 Condensate must be managed correctly and safety away from the unit. The unit should be installed in a way that prevents unauthorized access. The unit must not be installed in an area that is damp or could come into contact with water (such as a laundry room). The unit must not be exposed to direct sunshine or to other direct heat sources. The filter must be able to be removed and cleaned easily. The unit should be placed as far as possible from fluorescent lights so the remote control is not subject to interference. Care should be taken to prevent harmonics generated by loose or unsupported material in close proximity to a running unit. The unit must not be installed in an area that is exposed to salt, machine oil, sulfide gas, or corrosive environmental conditions. MS-SVX039A-EN 5.
