After the unit has been unpacked, perform the following procedure:
• Set the equipment on a stable ground.
• Set the unit under an appropriate cover that will protect it against the weather and at the distance
of 10 m from the blast chiller-freezer.
• Avoid putting the equipment close to a direct source of heat or in an area directly exposed to
sunlight.
• Maintain a distance of 500 mm from the air inlet and 1,500 mm from the air outlet.
• Connect the coolant hoses to the equipment.
• Ensure an appropriate circulation of oil in the vertical ducts.
• The equipment is delivered without the coolant.
6.4.2. ELECTRICAL CONNECTION
• The blast chiller-freezer must be connected with 2 electrical cables (the cross-section is stated
in the technical data) in accordance with the data specified in the wiring diagram on the
connections board in the condenser module. When connecting the condenser to the
connections board, observe the line number and the terminal number.
6.4.3. CONNECTION OF COOLANT HOSES
• Connect the liquid hose of the condenser to the liquid hose of the blast chiller-freezer.
• Connect the hot gas duct of the condenser to the hot gas duct of the blast chiller-freezer.
• Connect the suction duct of the condenser to the suction duct of the blast chiller-freezer.
• Open all closing valves in the system, leave the common cooling cycle, and check the tightness.
Fill the cooling equipment with the R404a/R507 coolant.
• If the condenser is set higher than the blast chiller-freezer, equip the system with appropriate
air traps.
When connecting both units:
• avoid reducing pieces;
• reduce all bends to a minimum;
• protect the pipes as appropriate, and
• provide the suction duct with appropriate insulation.
6.5. TIPS CONCERNING INSTALLATION
After the blast chiller-freezer has been set and connected, the technical staff should check if the
installation has been performed properly.
• Check proper operation of electrical connections.
• Make sure that the input power complies with the applicable standard.
• Make sure that the gas pressure in the cooling system is correct.
• Conduct at least one full cooling cycle in order to make sure that all parts of the equipment are
working properly.
• Before the startup, the equipment should be cleaned (see item 8.2).
• Such accessories as guides, frames, etc. should be installed as required at an appropriate
height.
