GENERAL INSTALLATION GUIDELINES
Outdoor Unit Location Selection
Planning for Snow and Ice, continued.
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 will create unsafe conditions. Properly install and insulate any drain hoses to prevent the hose from freezing, crack-
ing, leaking, and causing unsafe conditions from frozen condensate.
Choose an area where run-off water from defrost cycle will not accumulate and freeze on sidewalks or driveways. Properly install and insulate any drain
hoses to prevent the hose from freezing, cracking, leaking, and damaging the outdoor unit.
The indoor unit will take longer to provide heat, or heating performance will be reduced in winter if the unit is installed:
1. In a narrow, shady location.
2. Near a location that has a lot of ground moisture.
Tie-Downs and Lightning Protection
Tie-Downs
• The strength of the roof must be checked before installing the
outdoor units.
• If the installation site is prone to high winds or earthquakes, when
installing on the wall or roof, securely anchor the mounting base
using a field-provided tie-down configuration approved by a local
professional engineer.
• The overall tie-down configuration must be approved by a local
professional engineer.
Always refer to local code when using a wind restraint system.
Lightning Protection
• To protect the outdoor unit from lightning, it must be placed within
the specified lightning safety zone.
Table 5: Safety Zone Specifications.
Building Height (feet)
• Power cable and communication cable must be installed five (5) feet away from lightning rod.
• A high-resistance ground system must be included to protect against induced lightning or indirect strike.
If the building does not include lightning protection, the outdoor unit will be damaged from a lightening strike. Inform the customer of this possibility in
advance.
