Outdoor Unit - LG LH247HV Engineering Manual

Selecting the Best location for the outdoor unit
Select a location for installing the outdoor unit that will meet the following general conditions:
• A location strong enough 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 are within allowable limits.
• Where it will not be subjected to direct thermal radiation from other heat sources, nor an area that would not 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 operating sound from the unit will not disturb inhabitants of surrounding buildings.
• Where the unit will not be exposed to direct, strong winds.
• Where high-frequency electrical noise / electromagnetic waves will not affect operation.
• 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.
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost mode will not
accumulate and freeze on sidewalks or driveways.
• To avoid the possibility of fire, do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak.
• Don't install the unit in a location where oil, acidic solutions, sprays, or dust (sulfur, carbon, other corrosive materials) are present / often used.
• Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it.
Snow and Ice Conditions
In climates that experience snow buildup, place the unit on a suitably high platform to ensure proper condenser airflow. The raised support
platform must be high enough to allow the unit to remain above possible snow drifts. Mount the unit on a field-provided snow stand at a
minimum height that is equal to the average annual snowfall, plus 20 inches. Design the mounting base to prevent snow accumulation on
the platform in front or back of the unit case. If necessary, provide a field fabricated hood to keep snow and ice and/or drifting snow from ac-
cumulating on the coil surfaces. Use inlet and discharge duct or hoods to prevent snow or rain from accumulating on the fan inlet and outlet
guards. Best practice prevents snow from accumulating on top of the unit. Consider tie-down requirements in case of high winds or where
required by local codes.
The system may take longer to provide heat, or heating performance will be reduced in winter if the outdoor unit is installed:
1. In a narrow, shady location.
2. Near a location that has a lot of ground moisture.
3. In a highly humid environment.
4. In an area in which condensate does not drain properly.
