Center of Gravity
Due to our policy of continuous product innovation, some specifications may change without notification.
• Use appropriate moving equipment to transport each frame; ensure the equipment is capable of supporting the weights listed above. If the
equipment is not properly secured, it may result in an accident that causes physical injury or death.
• Wear protective gloves when handling equipment. Sharp edges may cause personal injury.
• Some products include polypropylene bands around the unit for packaging.
risk of the product falling and causing physical injury.
• Tear apart and throw away plastic packaging bags so that children may not play with them and risk suffocation and death.
• Consider the unit’s center of gravity is before lifting. Hoist the unit with the center of gravity centered among the lifting straps. There is a risk
of the product falling and causing physical injury.
• Lift the outdoor unit from the base at specified locations. Support the outdoor unit at a minimum of six (6) points to avoid slippage from the
rigging apparatus, and use a minimum of three (3) lifting straps. There is a risk of the product falling and causing physical injury.
• Use caution when using forklift to transport an unpackaged unit. Do not drop the unit when carrying it with a forklift. There is a risk of the
product falling and causing physical injury.
Place a protective cloth or other soft material at the locations where the casing comes in contact with the lifting straps to prevent damage to painted
surfaces.

Selecting the Best Location for the Outdoor Unit(s)
Selecting the Best Location for the Outdoor Unit(s)
• Do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak. These conditions can cause a fire, result-
ing 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.
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 may 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.
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”.
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 outdoor 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(s) / heat recovery units are 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’ts
• 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
MULTI V 5 Outdoor Unit Installation Manual
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
system 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 anticipated 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. Install a hail guard kit and air guide accessories (sold separately) to prevent snow or rain from accumulating on the fan inlet / outlet guards.
8. Consider tie-down requirements in case of high winds or where required by local codes.
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 may 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.
