Positioning

Preliminary warnings
The unit must be fixed to the supporting surface.

Positioning

1. Unit fixing bracket

• Make sure that:
  the supporting surface supports the weight of the appliance

• place the unit on a perfectly level surface

• fix the brackets to the supporting surface
  Make sure that:

•  it is levelled

• easy access is allowed to facilitate maintenance

Hydraulic connections

Preliminary warnings

The engineer is responsible for choosing the right wa-ter lines and their size, in accordance with good installation practices and the applicable law.
The hydraulic system is made by the installer and must be carried out with reference to the diagrams in this manual or on the website.
The hydraulic pipes connecting to the appliance must be suitably sized for the actual water flow rate required by the plant during operation. The water flow rate to the heat exchanger must always be constant.

Position and dimensions

1. Hydraulic connections 3/4″ (19 mm)

Hydraulic connection diagram

• A seawater circuit must be installed with a slope upwards.
• The unit overboard discharge must be installed as close as possible to the waterline to reduce noise and to be able to check visually the flow/output of the water circuit running.
• The seawater electric pump is needed to circulate the amount of water required in the heat exchanger.
• The pump should be installed in a sound-insulated environment.
• The pump must be mounted so that it is always at least 20 cm below the waterline
• Fix the pump on elastic supports.

Preliminary warnings

• T o allow maintenance or repair operations, each hydraulic connection must be equipped with the respective manual shut-off valves.
• Before connecting the piping, make sure that it do not contain stones, sand, rust or foreign matter that could damage the plant.
• The minimum nominal diameter of the connecting pipes must be 3/4″ (19 mm). Keep in mind that undersized piping determines malfunctions and/or loss of heating and cooling performance.
• The connection piping must be suitably supported so as not to bear on the appliance with its weight.
• Flush the plant thoroughly before connecting the unit. This cleaning process removes any residue, such as welding drops, slag, rust or other fouling from the pipes. These substances may otherwise settle inside and cause the appliance to malfunction.
• It is necessary to install a filtration system at the inlet of the appliance in an area accessible for maintenance, in order to protect the appliance from impurities in the water.
• Operating the unit without the water filter installed and clean is forbidden.

Condensation drain preparation

This appliance is complete with a tray for collecting the condensation produced during operation, which must be channeled to a suitable place for drainage.
The size and positioning of the drainage tube are shown below.

Preliminary warnings

• The condensate must be discharged in the bilge or in a special tank.
• If the line flows into a container (e.g. a tank), do not close the container hermetically and avoid immersing the draining pipe into the water.
• Since while operating the air conditioner sucks and then creates a slight vacuum in the environment, the drain pipe that goes directly or in the bilge or in a tank, it could suck it up and bring unpleasant smells into the cabin. To avoid this, it is appropriate to make a trap for blocking the air.
• When connecting the condensation drain, be careful not to squeeze the rubber duct.
• The direct discharge at side is not recommended because of sucking bad smells from the outside caused by the exhaust gas of its own or other engines.
• Do not discharge directly to the side.

Positioning

The unit is equipped with two drainage outlets. Use both outlets for faster drainage.

• Use plastic drainage pipes.

• Avoid pipes made of metallic material.

• Make sure all joints are sealed to prevent leakage of water.
  If using a tank for collecting the condensation:

• Avoid the hermetic closure of the container.

• Prevent the end of the drainage tube from falling below the water level.

Aeraulic connections

Preliminary warnings

• The engineer is responsible for choosing the right aer-aulic connections and their size, in accordance with good installation practices and the applicable law.
• The aeraulic system is made by the installer and must be carried out with reference to the diagrams in this manual or on the website.
• The air ducts connecting to the appliance must be suit-ably sized for the actual air flow rate required by the plant during operation.

2. Air delivery

Air outlet orientation

Connection to the system
Preliminary warnings

• Before connecting the piping, make sure that it do not contain stones, sand, rust or foreign matter that could damage the plant.
• The connection piping must be suitably supported so as not to bear on the appliance with its weight.
• The air ducts must be insulated and well stretched to allow good air flow.
• Avoid partial insulation of the pipes.
• Avoid installing the unit near heat sources.
• The system needs a correct air flow in order to work effi-ciently. It Is therefore important to get the correct distri-bution without bottlenecks , by maintaining the original nozzle diameter and not exceeding the recommended length of pipes.
