In Heating mode the HP alarm reason could be a poor air flow outlet. Check the air ducts are clean and free
from obstructions, check and clean the inlet air filter
The LP alarm reason is usually a refrigerant leak, check the refrigerant circuit to detect eventual leaks
The LT alarm reason could be a poor sea water flow, or a very low sea water temperature ( below 5 C° ).
Check first the sea water flow as described above.
6. 0 WORKING LIMITS
The unit operates correctly within the following ranges:
·
Summer cooling mode: 15°C < sea water temperature < 40°C
·
Winter heating mode: 5°C < sea water temperature < 20°C
Should working conditions be out of these ranges, in your particular application, please contact Uflex
before installation in order to find a suitable solution.
·
Localized situations: in some regions, it is common to experience a tremendous presence of jellyfish or
seaweed concentrated in back bay marinas for some periods of time. This can clog strainers, water pumps
and heat exchangers in a little while, causing shut-down faults and sometimes equipment damage. In such
particular conditions, please seek the advice of a local Uflex service representative. Any possible
modification to the overall system (self-contained, pumps, strainers, etc.) that could overtake the problem
must be approved by Uflex, otherwise warranty coverage will decline.
·
The pump is not self-priming: any damage incurred due to a pump running dry is not covered under
warranty. Air conditioning system must be switched off, as well as pumps, whenever there is a risk of pump
unpriming, due to particular seawater conditions related to the boat type and its speed. The compressor
could be damaged if the seawater flow through the heat exchanger is considerably reduced.
This air conditioning system is designed to work under normal operation conditions. Where failure or
malfunctions could lead to an abnormal operating condition that could cause injury or damage to any
equipment or other property, additional precautions must be designed into the control system. Other
devices (limit or safety control) or systems intended to warn of, or protect against failure or malfunction,
must be incorporated into and maintained as part of the system.
