CONDENSATE DRAINS
The condensate drain pan is 2” (50mm) high with two drain locations. During conditions of high humidity,
condensate may be produced at a rate of approximately a 1/2 gallon per hour (1.9 liters per hour). With this in mind,
it is important to route condensate drains downward to a sump pump. It is not recommended to route condensate
drains to the bilge. After the condensate drain installation is complete, test the installation by pouring water into the
pan and checking for proper flow.
For installation of the condensate drain:
● Attach a 5/8” I.D. reinforced hose to the hose barb and secure with stainless steel hose clamps.
● Install the condensate drain hose downhill from the unit and aft to a sump.
● Two drain fittings may be used and the hoses (teed) together using a tee fitting provided there is a
minimum 2" drop from the bottom of the base pan to the tee connection.
Do not terminate condensate drain line within three 3’ (914mm) of any outlet of engine, generator
exhaust systems, compartment housing an engine or generator, nor in a bilge, unless the drain is
connected properly to a sealed condensate or shower sump pump. Seal all condensate hose
penetrations.
BLOWER ASSEMBLY
You can achieve multi-directional supply air discharge from a single unit by rotating the blower to the desired
position. It is ideal for tight installations as 180° of rotation is available with which to position the blower. Its
advanced design allows the blower to be easily removed for rotating or servicing by removing 4 screws. Rotate the
blower to allow the most direct flow of air to the supply air grille.
MOUNTING BRACKETS
The a/c unit is supplied with a base pan that also serves as a condensate
pan. Mounting clip brackets (4) are provided to secure the base pan to a flat,
horizontal surface.
SUPPLY & RETURN AIR GRILLES AND TRANSITION BOXES
Install the supply air grille as high as possible in a location that will provide uniform air distribution throughout the
cabin. Grille louvers should be directed upward. The return air grille should be installed as low and close to the a/c
unit as possible to ensure direct uninterrupted airflow to the evaporator. The return air grille should have a
minimum four inches (4”) of clearance in front of it, free from any furniture or other obstructions. In no instance
should a supply air discharge be directed towards a return air grille, as this will cause the system to short cycle.
Allow for adequate clearance behind the supply air grille(s) for the transition box and ducting connection. See the
MAINTENANCE section of this manual for return air filter cleaning instructions.
