symbols. Failure to heed safety information increases the risk of personal injury, property damage, and/or product damage.
OPERATIONAL SAFETY
Installation and servicing of this system can be hazardous due to system pressure, moving parts, heat, and electrical
components. Only trained and certified service personnel should install, repair, or service equipment. When working on this
equipment, always observe precautions described in the literature, tags, and labels attached to the unit. Follow all safety codes.
Wear safety glasses and work gloves and place a fire extinguisher close to the work area. Do not work alone.
HOW IT WORKS
Your tempered water air conditioning system consists of the chiller, airhandlers installed throughout the vessel, freshwater
piping connecting the chiller to the airhandlers, and the seawater system. The chiller consists of three major components: the
compressor, the condenser, and the evaporator (or heat exchanger). The chiller is charged with a refrigerant that circulates
throughout these components. The airhandlers consist of two major components: the blower and coil. Fresh water circulates
through the piping from the chiller to each airhandler and back.
In cooling mode, warm cabin air is drawn (or blown) across the airhandler coil by the blower. Heat is removed from the air as it
passes across the coil. The cooled air is then blown back into the cabin. The heat from the cabin air is transferred to the fresh
water circulating through the coil. The warmed water is pumped back to the chiller. The water is circulated through the chiller's
WARNING
The word “WARNING” indicates hazards or unsafe practices which COULD result in severe personal injury or death.
CAUTION
The word “CAUTION” indicates hazards or unsafe practices which COULD result in minor or moderate personal injury,
product damage, or property damage.
WARNING
Never install your air conditioner in the bilge or engine room areas. Ensure that the selected location is sealed from
direct access to bilge and/or engine room vapors.
Do not terminate condensate drain line within 4 feet (1.2 m) of any outlet of engine or generator exhaust systems, nor
in a compartment housing an engine or generator, nor in a bilge, unless the drain is connected properly to a sealed
condensate or shower sump pump.
Failure to comply may allow bilge or engine room vapors to mix with the air conditioner’s return air and contaminate
living areas which may result in injury or death.
WARNING
Electrical shock hazard. Disconnect voltage at main panel or power source before opening any cover.
WARNING
To minimize the hazard of electrical shock and personal injury, chillers, airhandlers, and all electrically powered
equipment must be effectively grounded. Refer to installation guidelines for further information.
