UNIT INSTALLATION
EXPLOSION HAZARD
Do not apply flame or steam to a refrigerant
cylinder. If heat is needed to change faster,
partially immerse the cylinder in warm water.
> A cyclinder should never contain more than 80%
of liquid refrigant.
> Add only R-410A to an R-410A cylinder.
It operates at much higher presures than R-22.
Service equipment used with R-410A must be
listed.
>Do not use a cylinder as a platform or roller.
Always store a cylinder in a cool, dry place.
ELECTRICAL SHOCK HAZARD
> Ensure power source is OFF or disconnected at
main panel before opening any electrical boxes.
Failure to comply may cause serious injury or
death.
>It is imperative that the components of this
system are properly grounded to minimize any
electrical shock hazard and / or personal injury.
REFRIGERANT SAFE HANDLING
Because refrigerants are heavier than air, they can
push out oxygen from your lungs or from
enclosed spaces. To avoid death or difficulty
breathing, take the following precautions:
1- You should never sniff a refrigerant
2- No refrigerant should ever be purged into an
enclosed space or room. By law, all refrigerants
must be reclaimed.
3- If you suspect an indoor leak, you must
thoroughly ventilate the area before you begin
work.
4- If you do get contact with liquid refrigerant,
wear gloves and goggles to avoid frostbite or
blindness. If liquid refrigerant does get in your
eyes or on your skin, seek medical attention
immediately.
5- Refrigerant can cause poisonous gas to be
released if it is burned.
6- Always follow EPA regulations.
Read these instructions completely and then plan all connections
which must be made to the unit including ducting, condensate
drain line, seawater inlet and outlet hoses, electrical power
connection, location of control, and seawater pump placement, to
assure easy access for routing and future servicing for both
chilled water and air handler units.
Installation and servicing of this system can be hazardous due to
system pressure and electrical components. When working on this
equipment, always observe precautions described in the literature,
tags and labels attached to the unit. Follow all safety codes.
Wear safety glasses and work gloves and place a fire extinguisher
close to work area.

CTM Marine Chilled Water Systems Installation & User Manual
1 - The chiller unit is usually installed in the engine room.
Make sure to install the chiller unit in a horizontal surface strong
enough to hold the unit when the boat is in motion, choose a location
where it will be dry and able to be serviced easily. Allow at least between
3 - 4 feet (0.9 - 1.2m) of space around the unit and at least 3 feet (0.9 m)
above the unit.
2 - The control panel or electrical box which contains all the controls to
operate the chiller should be installed on a dry and flat horizontal or
vertical surface where it could be accessed easily for installation and
servicing. Make sure the location of the control panel is free of water
spray and moisture.
