EnviroComfort Installation Manual Very Important Safety Considerations
L-2657 ENGLISH 3
INSTALLATION PROCEDURES
VERY IMPORTANT SAFETY CONSIDERATIONS
This manual contains essential safety information concerning the safe and proper installation and operation of the
EnviroComfort direct-expansion air conditioner. It is very important that you read and understand the contents of this
manual thoroughly before attempting to install any Dometic equipment.
AVOID HARMFUL VAPORS
Consideration should be given to installing a trap in the condensate drain line(s) so that normal discharge of condensate can fill
the trap and prevent the ingress of carbon monoxide (CO) or other potentially harmful vapors.
ELECTRICAL SHOCK HAZARD
OTHER HAZARDS
Installation and servicing of this system can be hazardous due to system pressure and electrical components.
• 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.
INSTALLATION CHECKLIST
Review this list prior to and after installation.
AIR CONDITIONER UNIT MOUNTING
• Not in engine room or bilge areas, must be sealed away from exhaust or fumes.
• Proper spacing allowed around unit.
• Attached to solid, level platform with four hold-down clips provided.
• Condensate drain line routed aft and down hill to a sealed sump (not bilge), and should have a trap.
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 three feet 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
This component does not meet Federal requirements for ignition protection. Do not install in spaces containing
gasoline engines, tanks, LPG/CPG cylinders, regulators, valves or fuel line fittings. Failure to comply may result in
injury or death.
CAUTION
Electrical shock hazard. Disconnect voltage at main panel or power source before opening any cover. Failure to
comply may result in injury or death.
To minimize the hazard of electrical shock and personal injury, this component must be effectively grounded. Refer to
the installation guidelines for further information.
NOTE
United States federal law prohibits the intentional release of refrigerant gases into the environment, including the
refrigerant used in this air conditioning system. Special care must be taken when installing, charging and servicing
Dometic equipment to prevent any loss of refrigerant.
Dometic does not recommend the practice of using refrigerant to purge air and moisture from the system at
installation. This formerly used practice of purging is in violation of United States federal law.
