DUCT KITS AND POWERDUCT KITS
To achieve cool airflow through your ColdMachine, we offer four
different packages to improve ventilation:
FOR THE COLDMACHINE:
Part # C8079
Ventilation Duct Kit with adapter shroud, 3 ft. of 4” flex duct, 1
adapter flange and trim grille. Attaches to the condensing unit
with four screws. Can be used in two ways:
(1) To bring air to the unit from a cooler location—bilge, yacht
accommodation, cool ventilated locker, etc.,
or
(2) The condensing unit’s fan can be physically reversed and the
duct kit can be used to extract air from the unit and discharge
it into another space. This is preferred if the location has cool
air available, but has no way to get rid of the warmer air after
it has passed through the condensing unit.
Part # C8075
Power Duct Booster Duct Kit—as above, with 5 feet of 4” flex
duct, 3 adapter flanges and additional booster fan. Used exactly
like above, plus the longer length and push-pull fans” allow you
to go to a greater distance through the boat to pick up cool air or
get rid of heated air.
FOR THE SUPERCOLDMACHINE:
Part # C8070
Ventilation Duct Kit with 3 ft of flex duct, 1 adapter flange and
trim grille. Attaches to the SuperColdMachine condensing unit
with 4 existing fan mount screws. Can be used in 2 ways:
(1) To bring air to the unit from a cooler location—bilge, yacht
accommodation, cool ventilated locker, etc.,
or
(2) The condensing unit’s fan can be physically reversed and the
duct kit can be used to extract air from the unit and discharge
it into another space. This is preferred if the location has cool
air available, but has no way to get rid of the warmer air after
it has passed through the condensing unit.
Part # C8071
Power Duct Booster Duct Kit—as above, with 5 feet of 4” flex
duct, 3 adapter flanges and additional booster fan. Used exactly
like above, plus the longer length and push-pull fans” allow you
to go to a greater distance through the boat to pick up cool air or
get rid of heated air.
LOCATION CONSIDERATIONS
IMPORTANT:
Find the coolest possible location in the largest
compartment available. However, many other locations are
acceptable provided the appropriate ventilation duct kit is
installed (see below).
ENGINE COMPARTMENT
DUCT KIT OR POWER DUCT KIT MANDATORY.
Mount the condensing unit as far as possible from the engine,
particularly the hot exhaust pipe sections. Route the connecting
tubing from the evaporator away from the hot spots such as the
engine, manifold or hot water pipes. If the tubing must be run
close enough to local hot spots to become noticeably heated,
protect it with insulated sponge tubing (“Armaflex” or similar,
available from home improvement outlets).
IMPORTANT:
The condensing unit must be mounted
horizontally, base down.
NO EXCEPTIONS. It will tolerate up to
30° off-level but must not be mounted off-level initially.
SAIL BIN, LARGE LAZARETTE, OR ANY CLOSED COMPARTMENT
Generally adequate without ducting, if there is 100 cubic feet of
volume and half of the outside surfaces are below the waterline
for heat dissipation. In such a case, heat will transfer outside the
compartment via conduction. Be sure that airflow into and out of
the condenser is not obstructed by sail bags, lines, etc. Position
the unit so that it can still move air freely despite an occasionally
sail bag or two dropped nearby.
If above conditions cannot be met or if compartment air
temperature exceeds 100°F, you
MUST
install a duct kit.
UNDER A SETTEE, GALLEY COUNTER, BERTH OR LOCKER
(or any
space under 100 cubic feet)
Position the unit so that it can positively draw air from one space
and discharge it into another. Simply cutting holes or grilles into
the space will not accomplish this.
The best results are archived by cutting a rectangular opening in
the bulkhead equal to the size of the condenser (8” x 8”). Mount
the unit with its condenser against the opening for air intake.
Provide another opening of at least equal size at the other end
(or either side) of the unit so that warm air can exhaust. Small
slots or air holes generally are not satisfactory. One big opening
is much better. However, if visible finished joinery must be cut
into, plan to use teak louvered grilles (available in many stock
sizes from teak woodwork and marine hardware catalogs).
Increase the size of the outlet opening by at least 1/3 (ie: to
about 100 square inches or more) to compensate for the teak
louver obstruction.
