GENERAL INSTALLATION GUIDELINES

Location Selection

Selecting the Best Location
DANGER
• Do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak. These conditions can cause a fire, resulting
in bodily injury or death.
• Do not install the unit in a location where acidic solution and spray (sulfur) are often used as it can cause bodily injury or death.
• Do not use the unit in environments where oil, steam, or sulfuric gas are present as it can cause bodily injury or death.
Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. Follow the placement guidelines set forth in
"Clearance Requirements."
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off water from defrost cycle will not accumulate and
freeze on sidewalks or driveways, which may create unsafe conditions. Properly install and insulate any drain hoses to prevent the hose from freez-
ing, cracking, leaking, and causing unsafe conditions from frozen condensate.
Indoor units (IDUs) must not be placed in an environment where the IDUs may 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 factory-applied epoxy coating to the fan coils for each IDU.
Select a location for installing the outdoor unit that will meet the following conditions:
• Where there is enough structural strength to bear the weight of the unit.
• A location that allows for optimum air flow and is easily accessible for inspection, maintenance, and service.
• Where piping between the outdoor unit and indoor unit is within allowable limits.
• Include space for drainage to ensure condensate flows properly out of the unit when it is in heating mode. Avoid placing the outdoor unit in
a low-lying area where water could accumulate.
• If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), ensure that the site is well-ventilated and has a lot
of natural light (Example: Install on a rooftop).
Don't
• Where it will be subjected to direct thermal radiation from other heat sources, or an area that would expose the outdoor unit to heat or steam
like discharge from boiler stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumbing vents, and other sources
of extreme temperatures.
• Where high-frequency electrical noise / electromagnetic waves will affect operation.
Where operating sound from the unit will disturb inhabitants of surrounding buildings.
• Where the unit will be exposed to direct, strong winds.
• Where the discharge of one outdoor unit will blow into the inlet side of an adjacent unit (when installing multiple outdoor units).
Planning for Snow and Ice
To ensure the outdoor unit operates properly, certain measures are required in locations where there is a possibility of heavy snowfall or
severe wind chill or cold:
1. Prepare for severe winter wind chills and heavy snowfall, even in areas of the country where these are unusual phenomena.
2. Position the outdoor unit so that its airflow fans are not buried by direct, heavy snowfall. If snow piles up and blocks the airflow, the sys-
tem may malfunction.
3. Remove any snow that has accumulated four (4) inches or more on the top of the outdoor unit.
4. In climates that may experience significant snow buildup, mount the outdoor unit on a raised, field-provided platform or stand. The raised
support platform must be high enough to allow the unit to remain above possible snow drifts, and must be higher than the maximum antici-
pated snowfall for the location.
