WARNING:
Y Strainer MUST be installed on Intake of Chiller!
If any debris travels thro gh the connecting pipes from the
Fan Coils to the Braze PlateChannels of the Chiller, the will
ca se a "Frozen Spot" on the Plate and may ca se it to
r pt re.
To prevent this, a Y Strainer m st be installed on the Intake
of the Chiller. The Flow Switch and Low Press re Switch will
show normal reading. It is especially important to make s re
Marine Glycol / Marine Antifreeze to Water ratio is always
maintained at 30% Antifreeze to 70% Water.
Debris entering the Braze Plate Channels will res lt in
catastrophic damage and will not be covered by the
Warranty.

Warning: The Air Conditioning Unit is a
pressurized system; potential hazards can
cause serious injury. DO NOT ignore any
warnings in this manual.
Warning: It is required that trained and certified
professional personnel with experience in the
HVAC field to do the installation and service of
this system.
Warning: Never use Oxygen to pressurize a
refrigeration or Air Conditioning System.
Oxygen can explode on contact with oil and will
cause personal injury. When using nitrogen for
this purpose, use a regulation device that can
control pressure down to 1 or 2 PSIG.

Pre Installation:
Ocean Breeze equipment must be installed by a
certified HVAC Technician.
Determine installation location for each piece of
equipment. Note that each AC unit will require 2
feet of surrounding space to be free for access
to and from the unit.
Warning: Not allowing sufficient ventilation
around the unit will minimize performance, and
can cause potential damage to the equipment.
Next, locate all needed connections going to the
Condenser unit, Electrical box, Condensate
Drain, etc.
Make certain there is no power to any section of
the installation site. .
Electrical installation must be performed by a
license electrical contractor. It is highly
recommended to use a UL Approved Outdoor
Weatherproof Rated Electrical Panel Enclosure
for the Unit Breaker and Marine Grade Copper
Tin Electrical Wiring rated for 600 Volt.

Make sure the mounting surface is clean. When
installing the Condenser Unit, there must be a
minimum clearance to service the Condenser
Coil, Electric Box.
Lay out the power cables to the unit.
Use conduit or seal tight flexible conduit.
Lay out the Condensate Drain Piping as close to
overboard as possible. If you are reclaiming
condensate water run the pipe to the collection
area.
When the installation of the AC Unit Is complete,
be sure to clean up the area before continuing to
the Evaporator installation. Keep all
interconnection pieces sealed until needed to
avoid debris deposit in the tubes. If there is
more than one unit, repeat the above process.

INSTALLATION:
Reserve space for the electrical lines. Lay a
clear path for the Electrical lines to and from the
AC Unit.
Mounting the AC unit can be done in various
ways. If Ceiling Mount, make sure unit is level.
Clear paths for Discharge Air, Return Air and
condensate drain line with adequate space
around the Unit.
If installing Filter, make certain to reserve space
for easy access for intake of evaporator.
Once again keep the interconnections sealed
until ready to use.
ELECTRICAL INSTALLATION: Make sure all
electricity is powered off to the area before
installing the Fan Coil. A dedicated Circuit
Breaker should be used for the Fan Coil.
Install the power wires and the conduit to the fan
coil(s).

When mounting is complete, and electrical
connections are made, install the copper
refrigerant lines between each of the systems.

Check all line runs to and from each unit from
each Unit, inspecting the completed layout
carefully for any potential hazards that may pose
a problem in system operation. If laying duct
work, inspect surrounding space and allow
ducting to be flat and straight as possible from
point to point. Use UL Approved Ducting.
After all of the installation process is complete,
including correct connection of proper electrical
connections, and condensate drain lines,
ducting, return, proceed to the layout test.

WARNING:
READ THESE INSTRUCTIONS BEFORE
PROCEEDING
For 3 Phase Electrical...
I Compressor Makes Loud Noise, Power OFF
the Unit and Switch the Phase on the wires
connected to the Compressor Contactor
Output, (L1, L2, becomes L2, L1) etc.
Unit comes Precharged rom the actory.
DO NOT TAMPER with charge.
Please re er to any part o this Manual or best
results.
For urther assistance, please contact:
Ocean Breeze at 772 2200038.

Testing Procedure.
The layout test will prove the installation is
successful or if corrections need to be made.
Test each wire from point to point which will
provide added assurance that all the electrical
connection is correct. For Single Phase,
Common, Neutral and Ground are used.
Note: Wiring in Common and Neutral (Single
phase) can be interchangeable; however, not
recommended. Wiring in 3 Phase, must be
absolute: (L1 to L1, L2 to L2, L3 to L3, Ground
to Ground and so forth)
If Voltage Phase Monitor is installed in AC
equipment, check settings (480 Volt, 240 Volt,
etc).
A water test in the condensate line system will
prove the drain line will evacuate the water
safely to its destination whether reclamation,
sump, or overboard. The drain should be
constructed to have a dip and an air pilot tube to
maintain flow throughout.

The final test will be the refrigerant line pressure
test. One method is low pressure at 175 PSI
Nitrogen, a few ounces of refrigerant, and leak
detection hardware. Another method is only
with high pressure Nitrogen. High pressure
method is used at the factory up to 600 PSI
Nitrogen for One Hour with thermo graphic tools,
point sensors, visual inspection (safety pressure
impact attire must be worn on this test). On the
field, the low pressure test is preferred. For low
pressure and visual inspection, liquid detergent
soap can be used to check for bubbles on all
joints. If there are bubbles, a leak has been
discovered. If a leak has been identified on a
joint, use soft solder to seal it.

When using the low pressure testing method,
the process must be done carefully and the
inspection must be made at every connection
point. If all the tests are satisfactory, proceed to
final stages of installation. If there are any
problems, correct each problem and test each
solution, reinspect all problem points to make
certain the correction has been made and
successful. Repeat the above testing
procedures on the entire system.
When all tests are complete and there are
absolutely no issues, installation has been
complete.
Clean up the work areas, and apply weather
seals from both sides of throughways for lines.

After Leak Test, relieve all the pressure in the
system. If only Nitrogen was used evacuate into
the air by removing the stem valve from the
connection port. If you have not installed a stem
valve, disconnect the hose carefully. High
pressure Nitrogen is in the system and will
forcefully evacuate, posing a danger to the
installer (an impact of flying hose at such high
pressure can cause injury)
If the Low Pressure method was used, recover
the refrigerant with vacuum pump. Allow time
for the recovery process (20 minutes per ton) to
complete. The vacuum scale should be up to 30
HG negative pressure at sea level.
When ready to Power the system on for the first
time, the installer must charge the system with
refrigerant.
The Low Pressure Switch may have to be
bypassed for this process as the compressor will
most likely be shut down due to low pressure.
The Thermostat will also need to be bypassed
for the unit to maintain functioning until the
charging process is complete. When charging
the unit, the installer will meter refrigerant, check
electrical characteristics, measure air

temperatures, all in combination of the specified
scales for this system. There is a Sight Glass
installed on the unit to verify moisture in the
system. If there are unrelated problems
encountered, the installer is asked to contact
Ocean Breeze at 772 220 0038 for available
assistance to complete the installation.
