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.
