LMCN078HV Engineering Manual

Selecting the Best Location
Do’s
• Place the unit where air circulation will not be blocked.
• Place the unit where drainage can be obtained easily.
• Place the unit where noise prevention is taken into consideration.
• Ensure there is sufficient space from the ceiling and floor.
• Ensure there is sufficient maintenance space.
• Locate the indoor unit in a location where it can be easily connected to the outdoor
unit/branch distribution unit.
Don’ts
• Do not install the unit near a heat or steam source, or where considerable amounts of oil, iron powder, or flour are used.
• Do not install the unit where sulfuric acid and flammable or corrosive gases are generated, vented into, or stored.
• Do not install the unit near high-frequency generators.
• Do not install the unit near a doorway.
The unit will be damaged, will malfunction, and/or will not operate as designed if installed in any of the conditions listed.
Installation and Best Layout Practices
Using the Installation Guide
1. Choose an appropriate location for the indoor unit. To hang the installation guide, verify that it is
level and plumb, and then tape it to the wall.
2. Drill four (4) 1/4-inch diameter holes with a depth of 1-3/16 to 1-3/8 inches for the mounting
screws. Drill one (1) two (2) inch-diameter hole for the field-installed refrigerant and drain piping.
3. Insert a plastic anchor into each of the mounting holes.
4. Screw the top two (2) screws into the wall. Do not flush them to the wall; leave a 7/16 inch
space for hanging the indoor unit.
Figure 39:Using the Installation Guide.
Note:
If the unit is installed near a body of water, certain components are at risk of being corroded.
Appropriate anti-corrosion methods must be taken for the unit and all components.

Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas (oors, walls) in some rooms will be exposed to unconditioned
air (room will be above or next to an unheated garage or storeroom). To countermeasure:
• Verify that carpet is or will be installed (carpet will increase the temperature by three degrees).
• Add insulation between the floor joists.
• Install radiant heat or another type of heating system to the floor.
• Indoor units (IDUs) must not be placed in an environment where the IDUs will be exposed to
harmful volatile organic compounds (VOCs) or in environments where there is improper air make
up or supply or inadequate ventilation. If there are concerns about VOCs in the environment where
the IDUs are installed, proper air make up or supply and/or adequate ventilation must be provided.
Additionally, in buildings where IDUs will be exposed to VOCs, consider a third party factory-applied
epoxy coating to the fan coils for each IDU where the entire coil is dipped, not sprayed.
• If the unit is installed near a body of water, the installation parts are at risk of corroding. Appropriate
anti-corrosion methods must be taken for the unit and all installation parts.
