2 Setting up the HygroGen2
2.1 Physical Location
To ensure correct operation please ensure that:
1. The unit is level and stable;
2. There is at least 15mm clearance underneath and at least 100mm at the back of the unit to
enable adequate air flow;
3. There is adequate access to the electrical mains connection at the rear of the unit.
Note: The feet on the rear panel are for standing the unit for service purposes and to ensure a sufficient
air gap behind the unit. The unit will not operate in the vertical position.
2.2 Electrical Supply
Power Isolation
The unit is supplied with a mains cord set. The unit should be disconnected from the electrical supply
before the unit is moved, cleaned or has water added or removed.
Earthing
This unit must be earthed. Provision for the safety earth is made through the electrical mains connection
(see Figure 2(8) below) to which all parts of the unit requiring earthing are internally connected. An
earthed electrical supply is required.
Earth Leakage Current
Due to RF filtering, there is an earth leakage current, within the limits specified in EN 61010-1:2001. This
may affect mains power circuits protected by Residual Current Device (RCD) or Ground Fault Detector
(GFD) type circuit breakers (particularly if used in multiples or with other equipment with an earth
leakage current on the same supply circuit).
Overcurrent Protection
To protect the internal circuitry against excess currents, the mains supply to the unit must be connected
with the mains cord set provided with the unit and to an appropriate mains supply.
Voltage Rating
The unit is designed to work within the limits of a 110-230VAC 50-60Hz mains supply with voltage
fluctuations up to ± 10% of the nominal voltage. The unit is rated impulse-withstand (overvoltage)
