Attention: before repairing or servicing the unit, ensure that the electrical
supply is disconnected.
Any work on the unit must be carried out by trained people only.
2. APPLICATION FIELD
SIGMA 2002 units have been designed for cooling water or water-glycol and are generally used in air conditioning
or refrigeration applications.
See chapter 6 for recommended operating ranges.
2.1 GENERAL
- When installing or servicing the unit, it is necessary to strictly follow the rules described in this manual, to
conform to all the items detailed on the unit labels and take any necessary precaution.
- Pressure in refrigerant circuits and danger from electrical shock can be hazardous when installing or servicing the
unit.
3. INSPECTION, TRANSPORT, SITE HANDLING
3.1 INSPECTION
After receiving the unit, immediately check its integrity. The unit will have left the factory in perfect condition.
Therefore on receiving the unit any damage must be verbally described to the carrier and recorded on the
Delivery Note before it is signed by both parties. Blue Box or their Agent must be informed as soon as possible of
the extent of the damage.
The Customer should prepare a written statement and photographic evidence regarding any severe damage.
3.2 LIFTING AND SITE HANDLING
Avoid sudden movements and jolts when unloading and positioning the unit. Internal handling procedures must
be conducted with care. Do not exert leverage on the components of the machine. The unit must be lifted by
inserting steel tubes through the lifting attachments shown by the relative signs (yellow arrow).
The unit must be lifted by harnessing it as shown in figure 1: use ropes or straps of sufficient length and spacer
bars to avoid damage to the unit’s side panels and cover. Alternatively, the unit (with a maximum length less than
3.5 m) can be lifted by a forklift truck, inserting the forks under the pallet.
The warranty will be invalid if the rules described in this manual are not observed and if any modifications are
made to the unit without prior authorisation of the manufacturer.
