6.3 Location

6.4 Free room

When installing the unit leave enough free room to allow opening, correct use and easy maintenance in safe
conditions.

6.5 Installation

The unit is supplied filled with nitrogen to be discharged only when connecting the refrigerating system.
Connect the refrigerating system keeping dry nitrogen under a slight pressure; seal the pipes so that air humidity
can not contaminate the pipe inside (Note: POE oil is highly detergent. For this reason prevent any dirt from
getting into the pipes during installation).
for more than 15 minutes. Should this time be exceeded, replace the lubricant. (Note: when in contact with POE
oil, air humidity gives rise to a chemical reaction that can not be reversed under any vacuum conditions).
ATTENTION
Connect the discharge pipe of the safety valve (when available) using a copper pipe with
suitable diameter and dimensions as provided by law. Make sure that valve operation is not
hindered. The safety valve is provided with a joint with connection to be welded. Any gas
blowing out shall not cause any damage to people or things. Gas should be preferably
conveyed outwards.

6.5.1 Vacuum and charge

After the refrigerating pipes have been installed, act as follows:
Carry out a pressure test to check that all components are tight. Testing pressure should be higher than max.
operating pressure, as provided by law; in addition no permanent deformations should appear during the test.
To obtain optimal operation of the unit act as follows:
A) Place the unit in a well ventilated room, far from heat sources.
B) Limit the number of door openings.
C) Make sure that the unit has good air supply and discharge.
The compressor lubricant must not be in contact with the atmosphere
