EQUIPMENT INSPECTION
Inspect all cartons and packages for damages during transport. Remove shipping cartons and boxes
and check for concealed damages.
IMPORTANT!
the unit must be always kept upright.
Inspect refrigerant circuits for fractures or breaks. The presence of refrigerant oil usually indicates a
rupture in the refrigerant circuit.
WARNING!
The chiller heat pump unit is factory charged with refrigerant fluid R410A, having ODP=0
and GWP=1890 kg. The circuit is completely sealed by soldering therefore a gas leakage is very
unlikely to happen. However the R410A hazard identification is the following: Colourless, volatile
liquid with ethereal and faint sweet odour. Non-flammable material. Overexposure may cause
dizziness and loss of concentration. At higher levels CNS depression and cardiac arrhythmia may
result from exposure. Vapour displaces air and can cause asphyxiation in confined spaces. At
higher temperatures (>250°C) decomposition products may include Hydrofluoric Acid (HF) and
carbonyl halides.
Units that have been turned upside down or on their sides may have concealed damage to the
compressor, other parts or to the refrigerant system. If the unit is not upright when you receive it,
immediately file a claim with the freight carrier for concealed damages and follow these steps:
Set unit upright and allow to stand 24h on rest.
Attempt to start the unit after 24h.
If the unit does not start or makes excessive noise, return it to the freight carrier.
