L-2086 Installation
Site Location Checklist
• Unit is not located in an engine room or near an internal
combustion engine
• There is no obstruction of airow from return air grill to coil
• Seawater can be piped to the unit with no loops, dips, or
kinks
• Accessible for service and maintenance, including the return
air lter
• Adequate space for seawater and condensate drain connec
-
tions
•
Flat, horizontal and sturdy mounting location
• Condensate drain can be run continuously downhill from
unit to overboard tting or sump
• Space is sealed from the bilge or outside air
Mounting the Self-Contained Unit
Before mounting the unit, rotate the blower for discharge in
the desired direction by removing the screws from the blower
mounting ange and any supporting the rear of the blower,
then replacing all screws and remounting the electrical box (if
needed).
Mount the unit on a horizontal surface, and fasten securely
with the hold-down clips provided. If the unit has a detachable
electrical box and you wish to mount it remotely, it should be
securely fastened to a bulkhead or deck.
Route the condensate drain so that it ows freely to an over
-
board tting or sump. Do not permit condensate to puddle in
the bilge
. Note that most Cruisair self-contained units have two
condensate drains, one at each end. It is recommended that
you use both drains for best results, but if you choose to use
only one condensate drain, place the included plug in the other
hole.
Once the unit is correctly mounted, proceed to section titled
“Installing The Seawater Cooling System.”
Installing The Condensing Unit
This section applies only to remote condensing unit systems. If
you are installing a self-contained unit, skip this section and go
to “Installing The Seawater Cooling System.”
Selecting the Site
Cruisair condensing units are designed to be installed in any
convenient location. The unit is normally placed in the engine
room or other machinery space, but it can be located in the
living areas. The condensing unit will produce condensation so
a drip pan may be needed. The space around the unit can be
insulated to reduce noise if desired. The unit is internally cooled
and does not require ventilation.
Ignition Protection Warning
Most Cruisair remote condensing units meet federal
requirements for ignition protection. However, there are
some condensing units, such as those with 3 -phase
compressors, that are not ignition protected. Do not
install non-ignition protected units in spaces containing
gasoline engines, tanks, LPG/CPG cylinders, regulators,
valves or fuel line ttings. Failure to comply may result in
injury or death.
Site Location Checklist
• Adequate space for access to refrigerant, and seawater and
electrical connections
• Accessible for service and maintenance
• Flat, horizontal surface
• Away from direct spray from engine air intakes or water
washdown
• Maximum refrigerant tube run is 50ft (15m)
Mounting the Remote Condensing
Unit
Orient the unit so the refrigerant, electrical connections and
service ports are accessible.
On models with a plywood base, simply drill 4 mounting holes
through the base in appropriate locations and fasten the unit
with screws or bolts. Do not remove the plywood base or shock
mounts as they are part of the vibration and noise isolation
built into the unit.
Some models utilize a drain pan with bottom or side conden
-
sate drains. Screw or bolt through all corner holes of the pan to
mount the unit.
Do not remove any covers, caps or ttings that may expose any
wiring or refrigerant. Only remove these items when you are
ready to complete the installation. Removal of any covers may
result in damage to the electrical components. Removal of the
caps or ttings may result in refrigerant loss.
