6. High Pressure Switch Access:
All Mermaid marine air conditioners utilize a manual High Pressure safety switch. This
switch monitors the system’s high pressure any time the compressor is running. If a
condition occurs that causes the system high pressure to rise to a level that could damage
the compressor, the switch will activate and remove power from the compressor and
pump. Once activated, this switch must be manually reset. The switch is a green
cylindrical object with a red button . You must provide enough space to reach your
hand into the compartment or cut an access hole in the cabinet above or alongside
the switch to reset it after activation.
When the air conditioner is operating in the cooling mode only the lack of sufficient
cooling water can cause high pressure. In reverse cycle heat pump units operating in the
heating mode, high pressure can only be created by over heating of the evaporator which
is generally caused by insufficient return air or restricted supply air. The trouble
shooting guide covers these and other problems.
7. Condensation Removal:
Depending on the btu rating of your unit and the actual run time, the air conditioner will
remove from one to five gallons of water (condensation) from the air in a 24 hour period.
This water collects in the condensation pan to be drained out. Most boat owners will
drain this water into the bilge for removal overboard by the existing bilge pumps. When
running your condensation hose remember that condensation flows only by gravity and
the hose must never rise up any where along the way or condensation will backup into
the pan and overflow. This will not sink your boat, but it can get the surrounding area
very wet. In many boats it is not possible to drain to the bilge, and the condensation must
be removed by other means, such as a “Mermaid Condensator Kit”. Please contact your
Mermaid dealer or the factory for other options to remove condensation.

MANUAL FOR INSTALLATION AND INSTRUCTIONS PERTAINING TO THIS
PRODUCT. THIS MANUAL WILL BE INCLUDED UPON THE PURCHASE OF
THIS PRODUCT
The 24v thermostats come with a 20 foot power cable. One end of the cable attaches to
the BLACK terminal board on the side of the air conditioner electrical box. The other
end is wired into the black teminal board inside the thermostat itself.
The thermostat may be mounted on any flat wall surface with space behind the wall to
run the thermostat power cable out of view and still reach the air conditioner electrical
box. Ideally, the thermostat will be about 2/3 up on an interior wall, out of direct sun
