a. To be in accordance with I.E.E. standards, latest issue, or local codes of
practice as applicable.
b. Protected supply to incorporate fuses or motor rated circuit breakers to
specified rating, (see Data Sheet). H.R.C. fuses are recommended. An isolator
which disconnects all poles must be fitted adjacent to the dehumidifier.
c. All units must be correctly earthed/grounded. An earth leakage trip of the
current operating type is recommended to be fitted to all electrics. (If a heater
box is fitted, the same R.C.D. (residual current device) must feed both supplies.
d. IMPORTANT:- Inconsistent Electrical Supply.
The following Iimits of operation list not be exceeded if Calorex dehumidifiers
are to be guaranteed either in performance or warranty terms:
N.B. This voltage must be available at the dehumidifier whilst it is running under
full load.
The dehumidifier should be installed in accordance with EMC2004/108/EC.
Note: DH300 & DH600 dehumidifiers are fitted with a phase protection
relay and will not run if the phases are not connected in correct order (phase
sequence) or if the supply voltage is 15% less than the nominal voltage. (415V
for 3~N 50Hz). The lamp on the phase rotation relay, situated in the electric
box, is illuminated when the phases are correctly connected and the voltage is
sufficient.
