DANGER
Self-contained units or evaporators of split systems should never be installed in engine rooms or other
areas where fuel, battery or bilge vapors may be introduced to the living quarters on board.
These components do not meet federal requirements for ignition protection. Do not install in spaces
containing gasoline engines, tanks, LPG/CPG cylinders, valves, fuel line fittings, or regulators. Failure
to comply may result in injury or death.
Do not terminate condensate drain line within four feet of any outlet of engine or generator exhaust

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(s). Follow all safety codes.
Marvair recommends that you use only factory certified, EPA licensed refrigerant technicians and
qualified marine electricians. ABYC certification in both HVAC and Marine electrical trades is
desirable. In receiving these certifications, a technician and his employer has made a statement of
commitment to professional, technically proficient and reliable service.
CAUTION
Certain components will run at fairly high temperatures. Exercise care in working around operating
equipment. Do not touch operating machinery without the aid of qualified personnel, as referred to
above.
