b.  Maintain structural integrity.

Otherwise damage to product and/or boat
could occur.

The roof must be designed to support 60
kg when the boat is in motion. Normally
a 91 kg static load design will meet this
requirement.

c. Check inside the boat’s cabin for air distri-

bution box obstructions (i.e. space for doors
to open, room dividers, curtains, ceiling x­tures, etc.). See (FIG. 2).

2. Carefully mark and cut the required roof open­ing. See section, "C. Roof Requirements" on
page (4).

3. Using the roof opening as a guide, cut the match­ing hole in the ceiling.

4.  Maintain structural integrity. Oth­erwise damage to product and/or boat could
occur.

 NEVER create a low spot on boat
roof. Otherwise, water will pool and could cause
a leak.

The opening created must be framed to pro­vide adequate support and prevent air from be­ing drawn from the roof cavity. Framing stock
19 mm or more in thickness must be used.
Remember to provide an entrance hole for
power supplies at the front of the opening. See
(FIG. 3).

OPERATING INSTRUCTIONS

A. Controls

1. The Selector Switch has 10 positions including
“OFF”. This controls fan speed, optional heating
mode, and cooling modes. See (FIG. 18).

FIG. 18

2. The thermostat controls the temperature range
at the lter between approximately 18 °C and
32 °C.

B. “OFF” Position

1. This is to turn unit off.

C. Cooling Operation

1. Set the thermostat at the desired temperature
level.

2. Select the fan speed that best satises your
needs:

a. HIGH COOL: Selected when maximum cool-

ing and dehumidication required.

b. MED. COOL: Selected when normal or aver-

age cooling required.

c. LOW COOL: Selected when room is at de-

sired comfort level and needs to be main­tained. Normally this speed used for night time
operation.

The blower runs continuously to circu­late air and maintain an even temper­ature. The compressor will come on
as cooling is required to maintain the

selected temperature level.

D. Heating Operation (With Optional

Electric Heater Installed)

This electric heater will NOT replace a fur-
nace for heating your boat in cold weather.
The intent is to remove the chill on cool days
or mornings using a 1.6 kW heater.

1. Turn the selector switch to “HEAT”. There are
three positions: HIGH FAN, MED FAN or LOW
FAN to select from, depending upon personal
choice. See (FIG. 18).

2. Use low fan speed with the electric heat strips
(use of higher speeds will make the outlet air
feel cool, but all heating speeds deliver the same
watts of electric heat to the boat).

3. The heat strip will come on and begin heating.

4. The element will “cycle off” when the thermostat
is satised. The fan will continue to run help­ing keep the temperature throughout the boat
uniform.

E. Fan Operation

1. This will circulate the air in your boat without
cooling or heating. There are three positions:
HIGH FAN, MED. FAN or LOW FAN to select
from, depending upon personal choice.

10

MAINTENANCE

A. Air Filter

1. Periodically (a minimum of every 2 weeks of op­eration) remove the return air lter located be­hind the return air grille and wash it with soap
and warm water, let dry and then reinstall.

NEVER run the unit without return air l-
ter in place. This will plug the unit evapo­rator coil with dirt and may substantially
degrade the performance of the unit over
time.

B. Air Distribution Box Housing

1. Clean air distribution box housing and control
panel with a soft cloth dampened with a mild de­tergent. Never use furniture polish or scouring
powders.

C. Fan Motor

1. The blower motor is factory lubricated and re­quires no service.

D. Frost Formation On Cooling Coil

1. Frost on a small portion of the coil is not un­usual. Under certain conditions, ice may form
on the evaporator coil. This is indicated by very
cold output at very low air speed and the icing
can be seen through the air inlet hole with the

lter removed. If this should occur, inspect the
lter and clean if dirty. Make sure air vents are

open and not obstructed. Units have a greater
tendency to frost when the outside temperature
is relatively low. This may be prevented by ad­justing the thermostat control knob to a warmer
setting (counter clockwise). Should frosting con­tinue, operate on any FAN ONLY setting until
the cooling coil is free of frost; then resume nor­mal operation. If frost condition persist, contact
your local service center for assistance.

E. Heat Gain

The ability of the air conditioner to maintain the desired
inside temperature depends on the heat gain of the boat.
Some preventative measures taken by the occupants of
the boat can reduce the heat gain and improve the perfor­mance of the air conditioner. During extremely high outdoor
temperatures, the heat gain of the boat may be reduced by:

● Mooring the boat in a shaded area

● Using window shades (blinds and/or curtains)

● Keeping windows and doors shut or minimizing
usage

● Avoiding the use of heat producing appliances

● Adding heat-rejection lm to windows

Operation on High Fan/Cooling mode will give optimum

or maximum efciency in high humidity or high outside

temperature.
Starting the air conditioner early in the morning and giv­ing it a “head start” on the expected high outdoor ambient
temperature will greatly improve its ability to maintain the
desired indoor temperature.

F. Condensation

The manufacturer of this unit will not be responsible for
damage caused by condensation forming on ceilings,
windows, or other surfaces. Air contains water vapor which
condenses when temperature of a surface is below Dew
point. During normal operation this unit is designed to
remove a certain amount of moisture from the air, depend­ing on the size of the space being conditioned. Keeping
doors and windows closed when this air conditioner is in
operation will greatly reduce the chance of condensation
forming on interior surfaces.

This warranty gives you; the purchaser, specic legal rights, and you may also have other rights which vary from state to state. You
also have implied warranty rights, including an implied warranty of merchantability, which means that your product must be t for

the ordinary purpose for which such goods are used. The duration of any implied warranty rights is limited to the duration of
the express warranty as found in Section C. Some states do not allow limitations on how long an implied warranty lasts, so the

above limitation may not apply to you.

Installation and application of Dometic components is not warranted by Dometic, because Dometic has no control or
authority over the selection, location, application, or installation of these components.

C. COVERAGE PERIOD

What is the period of coverage?

(See Limited Warranty Periods at the end of this book).

All Dometic components bear a data plate on which there are model and serial numbers. The serial number is date coded. To
determine whether or not any Dometic component is in warranty, proceed as follows:

1. Determine the manufacture date of the component from the serial number on the data plate. If you are not familiar with the
date code, write or call the Dometic Customer Service Department to obtain the manufacture date. The hours of the Cus­tomer Service Department are 8:00 a.m. - 5:00 p.m. (USA, Eastern Standard Time Zone) Monday through Friday excluding
holidays.

2. It is possible that there might exist a considerable time lag between the date a component is manufactured and the date it
is put in service. In such instances, the date of manufacture could indicate that the item is out of warranty. However, based
on the date the equipment is rst put in service, the item may still be covered by the Dometic warranty as described in
Section A. For proof of date put in service, Dometic will require a copy of the bill of sale of the Dometic equipment from the
installer or new boat dealer to the original owner.

D. GETTING SERVICE

How do you get service?

Please read the following Warranty Procedure:

If the failure of a Dometic component is determined to be covered under the Dometic warranty and the time in service is determined
to be within the warranty time limit, the owner has the following three options:

1. Preferred option: Have a Dometic authorized Servicing Dealer, perform the work needed. The customer needs to call
Dometic Customer Service Department for a recommendation as to the closest dealer. If the customer already knows an
authorized servicing dealer, the dealer should be contacted directly.

2. Second option: If the customer contacts Dometic Service Department for a Servicing Dealer and Dometic has no one in that
particular area, Dometic will authorize the use of a local service company and Dometic will work with the local company to
assist in any way possible.

3. Third option: The customer may send his equipment back to the factory to have the repair work done. Dometic will make
every effort to return the equipment to the customer within a three week time period. If the claim represents a legitimate

warranty problem, Dometic will pay the freight both ways. Dometic prefers option one rst, option two second, and option

three only if one and two are not available.

The customer may contact the Dometic Service Department at 954-973-2477 Monday through Friday, 8:00 a.m. - 5:00 p.m. East­ern Time. After hours (evening and weekends) technical support is offered through Dometic's 24/7 Hotline at 888-440-4494.
