4 ELECTRICAL CIRCUIT
4.5 - MULTIPLE INSTALLATION
The CABIN air-conditioner is particularly suggested for a multiple installation. A multiple installation has these
specific features:
- One only sea water pump supplies water to all units.
- Each unit must have its own setting of compressor starting delay ( see 4.6 ).
4.5.1 - PUMP CONNECTION IN A MULTIPLE SYSTEM - C 307
In order to run the same pump from several units, it is available as option a pump relay box. Each air-condi-
tioner is connected to the pump relay box. The mains supply to the pump relay box must be independent from
the air-conditioners and protected by an independent fuse. The pump supply will come in parallel from each
relay controlled by each air-conditioner.
