Thank you for choosing a Gram Commercial CO
2
product.
This manual is made to aid the following:
• The installer when integrating the Gram CO
2
product into a remote CO
2
installation.
• The service technician when servicing the cabinet.
BE AWARE:
Only technicians who have the right skill level regarding how to work on a CO
2
system and who have the
sufficient knowledge regarding the chosen controller, are allowed to carry out the installation regarding
connecting to the external system and adapting the controller parameters to fit the installation.
In order to make sure that the cabinet is connected and used as it is intended the below points must be
taken into consideration:
• Not to exceed PS on neither of the system sides (PS limits to be secured by the installer/safety
valves):
o PS
LP-side
= 60 bar
o PS
HP-side
= 90 bar
• Be aware of and instruct the end user only to use the cabinet as described under intended use.
• If the controller parameters are not adapted/adjusted correctly it can lead to severe damage to the
refrigeration system. This is the reason why sufficiently skilled personal is needed in order to be
able to correct/adapt the controller settings, making the cabinet and the external system run in
harmony. (All controller parameters should be checked by the installer prior to starting up the
product).
This product is intended for professional use, meaning storing packed food stuff at a constant temperature.
The product may not be used to chill or freeze food stuff. For that purpose, use a blast-chiller or a blast-
freezer.
The product is only to be used for the purpose it was designed for (storing already chilled or frozen food
stuff, which is packed or in closed containers).
Any unintended use can result in the food stuff inside the product, not being kept at the right temperature.
