4. Technical features
(figures F. 14 and F. 15 )
The unit’s technical features and CE marking are given on the data plate attached to the cooling unit.
5. Transport and handling
During transport and storage the cooling unit must be kept in a vertical position, as indicated on the packaging (figure
F.01 ), and must not be exposed to temperatures above 70°C or below -20°C. Upon receipt, check that the packaging has
not been damaged during shipping. To lift the cooling unit in a safe manner the two supplied M6 eyebolts may be used;
these should be fitted into the threaded inserts located on the top of the cooling unit (figure
F.03 ).
6. Installation
Installation of the unit should only be performed by qualified and authorised personnel. The cooling unit must be
installed with the enclosure air intake hole in the highest possible point. Ensure the fixing elements and couplings will
not interfere with the equipment inside the enclosure itself. If the cooling unit is to be installed on a door, make sure
the door can take the weight. The unit must be installed in the vertical position indicated. Maximum permitted deviation
from the vertical is 2°. Disconnect power before starting any work inside the switchboard. The cooling unit must be
installed on the outside of the electrical switchboard. If semi-recessed installation is required (fig.
F.06 ), the
corresponding accessory must be used. This is available upon request as an optional extra. Depending on the installation
option, drill the holes and make the necessary cuts in the switchboard (figure
F.06 ) using the drilling template supplied
with the unit. Fit the sealing strip on the cooling unit on the side connected to the enclosure and follow the assembly
diagram (figure
F.06 ).
7. Condensate discharge hose
The condensate which, depending on the ambient temperature and humidity conditions, forms on the heat exchanger
which cools the enclosure air, is not a malfunction but a normal phenomenon of the cooling unit. In models
EGO04-
EGO06 , this condensate is taken outside through a hose at the bottom of the cooling unit. The transparent plastic hose,
supplied with the unit, must be connected to this outlet (figure F.10 ). This plastic hose can be connected to another one
with the same diameter to carry the condensate to another point, allowing it to be discharged where there can be no
slipping hazard for personnel. In this case, make sure the condensate flows without any hindrance. Avoid horizontal
lengths of more than 0.5 metres, uphill sections and the accidental formation of traps (figure
F.07 ). The end of the
condensate discharge hose must always be free and not underwater, so never place the end of the discharge hose inside
a condensate collection container (figure
F.08 ). Models EGO08 to EGO40 are fitted with a condensate evaporation
device which operates via the hot (outlet) tube of the compressor (Fig. F.13 ). These models nevertheless have an
emergency condensate outlet which can be carried outside as described above. If the cooling unit is used with the doors
of the enclosure open, excessive quantities of condensate will form and this is an unauthorised condition of use (figure
F.09 ). We suggest using a position switch on the door connected to the cooling unit’s digital input to stop the unit if the
door is opened. (See section 8.3 )
8. Electrical connection
8.1 Safety
Warning! Electrical connections must only be performed by specialised and authorised personnel. Switch power off
to the enclosure before making the connection.
Check that there is no power to the switchboard and that the supply
voltage corresponds to the characteristics given on the cooling unit’s data plate. The power supply must be protected
using appropriate time-delay fuses (type T) or circuit breakers with K-curve, per the indications given in table F.14 .
Connect the power-supply cables to the black connector included with the unit, following the indications given in figure
F.04 . Disconnect the cooling unit before performing testing on the enclosure.
8.2 Two-phase models with autotransformer
(EGO06G / EGO08G / EGO10G / EGO12G /EGO16G)
These two-phase models can operate with two different supply voltages: 440V 2~50-60Hz and 400V 2~50-60Hz. If the
available power supply is 440V 2~50-60Hz, connect terminals L1(0) and L3(440) on the terminal board (figure
F. 04 ). If,
on the other hand, the available supply voltage is 400V 2~50-60Hz, connect terminals L1(0) and L2(400) on the same
terminal board.
