3.14.4 Valves
For a proper connection to the mains water supply Oxycom advises the
contractor to use the following valves in the installation:
-
An additional shut-off valve to isolate the IntrCooll® from the water supply, i.e.
during maintenance activities or when taking the system (temporary) out of
service.
- An automatic aeration valve to ensure proper drainage of the water supply
line.
- A maintenance valve and freshwater connection near the unit, for
maintenance reasons (i.e. water supply for pressure washer).
These valves are not included in the package and must be provided by the
contractor.
Note
When several units are linked together make sure each one can be shut-off from
the water supply separately for maintenance purposes.
3.15 Electrical requirements
3.15.1 Unit specifications
Refer to the specifications of the IntrCooll® on page 67 for all specifications of
the IntrCooll® Std. and Plus.
3.15.2 Power supply fuse
Oxycom demands the installation of an automated circuit breaker between the
power source and the IntrCooll®. The external fuse must comply to the following
specifications:
-
3P+N
- At least 16A
- Type C
An automated circuit breaker is not included in the package and must be
provided and installed by the contractor.
Note
The diameter of the power supply line depends on the length, position,
temperature and if the wires are bundled or not. Therefore, a calculation must
be executed to determine the correct diameter of the power supply line.
3.15.3 Power isolating switch
Danger
Risk of electrical shock. When the switch is in OFF position, mains voltage always
remains present between the switch and the mains connection.
