Piping Limitations and Placement Considerations

Due to our policy of continuous product innovation, some specications may change without notication.

DANGER

Selecting the Best Location for the Water Source 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.

• Water source units are not weatherproof. Always install water source units indoors. Failure to follow this installation guideline can create an

electrical hazard that can result in bodily injury or death.

Select a location for installing the water source unit that will meet the following conditions:

• Where the floor is waterproof and can bear the weight of the unit(s). The floor must contain a liquid drainage system and must have a slight

slope to aid in liquid drainage.

• Where there is enough strength to bear the weight of the water source unit.

• A location that allows for optimum air flow and is easily accessible for inspection, maintenance, and service.

• Where piping between the water source unit and indoor unit(s) / heat recovery units are within allowable limits.

• Install the unit(s) in a separate machine room not exposed to external air.

• Install the unit(s) in a space where the ambient temperature is within 32 to 104°F.

• Have an anti-freeze plan for the water supply if the unit(s) is stopped during cold weather.

Don’ts

• Where it will be subjected to direct thermal radiation from other heat sources, or an area that would expose the water source 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 not affect operation.

• Where operating sound from the unit will disturb inhabitants of the building.

• Where there is carbon fiber or combustible dust.

PLACEMENT CONSIDERATIONS

For placement considerations for Heat Recovery Units, refer to the applicable Engineering Manual on www.lghvac.com.

For detailed placement considerations and installation requirements for indoor units, refer to the applicable Indoor Unit Engineering and / or

Installation Manuals.
