Risk of leaking water. Can cause property damage.
This product may use circulating water under pressure.
This product requires a free-flowing drain.
Freezing or other abnormal conditions could cause leakage or overflow. Uncontrolled
water can cause expensive damage to buildings and other equipment. Do not locate this
product above any equipment that could be damaged by water.
NOTICE
Risk of explosive pressure release. Can cause injury or death.
This product contains refrigerant liquid and vapor under high pressure. Some
installation and service procedures could expose personnel to the risk of explosive dis-
charge. Some startup procedures could expose personnel to the risk of frostbite from
release of refrigerant.
Reclaim refrigerant to reduce the pressure to atmospheric before working on pipes,
valves, heat exchangers, compressors, pressure switches, etc.
Once opened, do not close any manual refrigerant valves that might isolate
refrigerant from the relief valve. If necessary, install relief valves (by others).
WARNING
NOTICE
Risk of uncontrolled condensation. Can cause property damage.
This product is intended to control relative humidity and temperatures. Improper
design, installation, and/or operation can lead to uncontrolled condensation of water, with
associated property damage.
Read and follow the instructions in this manual. Optional material will be noted as
being optional. All other material should be considered as important to the proper
function of the product.
Risk of contamination of breathing air. Can cause injury or death.
Application of this product may involve the intake of outdoor air. The point of intake
must be carefully chosen to prevent intake of contaminants.
Application of this product may involve air-handling equipment, e.g. ducts, cabinets,
plenums, etc., which operate below atmospheric pressure. Such equipment must be
carefully located and installed to prevent the intake of contaminants.
Follow the instructions in this manual and all applicable codes.
WARNING
Risk of frostbite. Risk of eye damage.
Improper handling of refrigerants and refrigerant hoses can allow release of liquid
refrigerant. Exposure to liquid refrigerant can cause frostbite and severe eye damage.
Wear gloves, eye protection, and any other appropriate protective equipment. Follow
all safety procedures.
WARNING
Risk of suffocation.
Improper handling of refrigerants and refrigerant hoses can allow release of refrigerant
gases. In a confined space, these heavier-than-air gases may accumulate and dis-
place oxygen, leading to suffocation.
Confirm adequate ventilation before proceeding.
