GENERAL INSTALLATION GUIDELINES
Selecting the Best Location for the Outdoor Unit
DANGER
•Do not install the unit in an area where combustible gas will 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.
WARNING
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on
sidewalks or driveways, which will create unsafe conditions. Properly install and insulate any drain hoses to prevent the hose from freezing, cracking,
leaking, and causing unsafe conditions from frozen condensate.
WARNING
Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. Vermin and unauthorized individuals will

Select a location for installing the outdoor unit that will meet the following conditions:
• Where there is enough 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).
Do Not’s
• 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 windchill 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 will malfunction.
3. Remove any snow that has accumulated four (4) inches or more on the top of the outdoor unit.
4. In climates that will 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.
5. Design the mounting base to prevent snow accumulation on the platform in front or back of the unit frame.
6. Provide a field fabricated snow protection hood to keep snow and ice and/or drifting snow from accumulating on the coil surfaces.
7. To prevent snow and heavy rain from entering the outdoor unit, install the condenser air inlets and outlets facing away from direct winds.
8. Consider tie-down requirements in case of high winds or where required by local codes.
