1.0 INTRODUCTION
The unit you have purchased has been designed and manufactured following high quality
standards, in order to achieve the best performances over the time. Parts and materials have been
selected to give the highest reliability. Every single unit has been checked and tested after
production, verifying performances in heating and cooling mode, acoustic levels and electrical
safety, EN 60204-1.
2.0 EQUIPEMENT INSPECTION
2.1 UNPACKAGING AND INSPECTION
Inspect all cartons and packages for damages during
transport. Remove shipping cartons and boxes and check for
concealed damages.
To unpack the unit follow these steps:
1.
Cut the plastic straps that hold
the shipping carton closed;
2.
Pull up and remove the shipping
carton and the polystyrene
protections;
3.
Remove the fixing screws of the 4
fixing brackets that lock the
machine to the wooden pallet;
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.
