6.4.1. SETTING UP
After unpacking the condensing unit, follow the instructions for a proper installation:
•Set up the unit straight and on a solid surface.
•The refrigeration unit is suitable for an indoor and outdoor installation.
•For an outdoor installation, appropriate weatherproof housing must be provided.
•A suitable weatherproof housing can also be found in our accessories pricelist.
•The distance between the condensing unit and the blast chiller should be as close as possible.
•Do not install in direct sunlight or close to heat sources.
•A minimum clearance of 500 mm must be maintained on the air intake side and a minimum
clearance of 1500 mm on the air exhaust side.
•The refrigerant lines should be installed with a downward slope to the refrigeration unit.
•Appropriate oil recirculation must be provided in riser lines.
•The units are delivered without any refrigerant charge.
6.4.2. ELECTRICAL CONNECTION
Connect the blast chiller to the switch panel in the condensing unit via 2 electrical cables (the
minimum cross-section of which is specified in the technical data sheet) according to the
specifications in the wiring diagram. When connecting the condensing unit to the switch panel, adhere
to the wire and terminal numbers.
6.4.3. CONNECTION TO REFRIGERANT LINE
•Connect the liquid line of the condensing unit to the liquid line of the blast chiller.
•If the refrigeration unit is installed at a higher level than the blast chiller, the pipes must be
equipped with appropriate siphons.
•Connect the suction line of the condensing unit to the suction line of the blast chiller.
•Open all shut-off valves of the system and evacuate the entire refrigeration circuit and check
for leaks. Fill the refrigeration system with R452A.
Note the following when connecting the two units:
•Avoid reductions.
•Reduce possible bends to a minimum.
•Fit and attach the pipe in a suitable way.
•Provide the suction pipe with a suitable insulation.
6.5. INSTRUCTIONS FOR THE INSTALLING TECHNICIAN
After the blast chiller has been installed and connected, the technical personnel must check that the
installation has been carried out correctly.
•Check the correct operation of the electrical connection.
•Before commissioning, the unit should be cleaned (see chapter 8.2).
•Insert accessories, such as support rails, grids, etc. at the appropriate height, as required.
•Make sure that the power consumption is according to the standard.
•Make sure that the gas pressures of the cooling system are correct.
•Run at least one complete cooling cycle to ensure that all parts of the unit are functioning
properly.
