5.1.- SEA WATER PUMP CHECK
1.- Set the thermostat knob on "24" all clockwise.
2.- Push the "Cool" button.
3.- Check that pump is running smoothly and that the water flow meets the unit specifications. The fan runs
at the chosen speed.
5.2.- COOLING MODE CHECK
With the unit, as at 5.1:
1.- Turn slowly the thermostat (TEMP) knob counter clockwise towards "18" until the compressor starts.
2.- Check that after few minutes the air out starts cooling. If the unit is left running for a while the thermostat
setting and the condensate drain can also be checked. In fact, if the air is sufficiently humid, the unit will soon
start to produce condensate water, which must be discharged over board.
5.3.A- HEATING MODE CHECK
With the unit OFF, turn the temperature knob clockwise towards "24", put the fan switch on "MAX" and push
the "HEAT" button. Check that after few minutes the air out begins to warm up. If the unit is left running for a
while, the thermostat setting can also be checked.
5.3.B- HEATING MODE CHECK
With the unit OFF, turn the temperature knob clockwise towards "24", put the fan switch on "MAX" and push
the "HEAT" button. Check that after few minutes the air out begins to warm up. If the unit is left running for a
while, the thermostat setting can also be checked.
NOTE: With electrical heating the compressor and the pump do not run. The air out will be warmer if the fan
runs on minimum speed.
5.4.- SEA WATER CIRCUIT CHECK
During any running cycle, both cooling and heating, one should check the tightness of all the water fittings
and pipings with special care to the parts of the circuit below thw water line. The water flow check (request-
ed at 5.1) can be done at the outlet over board or in line with a water meter.
5.5.- SEA WATER PUMP AMP CHECK
Because of water circuit being different from one to another installation, one must check that the pump is run-
ning within its range. During the pump running, check the amp draw with an amp meter. The amp draw should
never exceed the figure printed on the pump. If it exceeds, stop the unit and check the water circuit (see 3.7)
5.6.- CHECKING AND BALACING THE SYSTEM
It is extremely important to check and eventually to balance the air distribution system. This is necessary to
get the maximum efficiency from the air-conditioner. This test is only an air flow test: you don't need to run the
compressor but only the fan and it will be possible to check the system in the same yard, out of water, only
connecting it to mains supply. The measure should be taken at the return grill in order to obtain the total air
flow of the system using an adequate anemometer.
