The plate exchanger is always protected by a protective heating cable for the secondary circuit containing water.
If there are pumps installed on the secondary circuit, and it is an outdoor unit, the volutes are always protected by a heating
cable as well as pre-installed pipes.
The installer must protect any connecting pipe sections between the indoor system and AQUA Link
For temperatures below -15°C (i.e. for glycol perce ntages between 30% and 40%) a series of heating elements designed to
protect the main parts (pump motors, valve bodies...) and the electrical control board must be set up
For operation at temperatures outside the aforementioned range, it is necessary to contact our Technical Office.
Units without glycols:
No glycol units in the indoor and outdoor version of the primary circuit are designed and built to operate at outdoor air
temperatures between +3°C and +45°C which therefore do not subject the water in the circuit at risk of freezing. For
operation at temperatures outside of the aforementioned range, it is necessary to contact our Technical Office. Heating
cables are part of the standard supply of units installed outdoors, against accidental low temperatures to protect: pump
volutes, mixing manifolds, pipes inside the machine. WARNING: it is the installer's responsibility to protect the sections of
the machine's infeed and outfeed pipes that lead to the chilled beam circuit and chiller, including the inertial tank.
Warning: Before performing any operation on the unit make sure the power supply has been
disconnected.
Any operation on the unit must be performed by qualified personnel.
Failure to comply with the instructions in this manual and any change made to the unit without prior written consent, will
immediately render the warranty null and void.
2. INSPECTION, UNPACKING, TRANSPORT
2.1 INSPECTION
After receiving the unit, check its integrity: the machine left the factory in perfect condition, so any damage must be
immediately reported to the carrier and noted in the Delivery Sheet before signing it.
Blue Box or your Agent should be made aware of the extent of the damage as soon as possible. The Customer must fill in a
written, photographic report concerning any relevant damage.
2.2 UNPACKING
The packaging of the unit must be removed carefully to avoid causing damage to the machine.
The packaging materials are of a different nature; wood, cardboard, nylon, etc. It is good practice to store them separately
and deliver them to specialised companies for disposal (or recycling), which must be done according to standards in force in
the Country in which installation is being carried out, thereby reducing environmental impact.
2.3 LIFTING AND TRANSPORT
Avoid any abrupt movement while unloading and positioning the unit; when transporting the equipment indoors, pay the
utmost care. Do not use the machine components as anchors. The unit must be lifted using steel pipes inserted in the
eyelets indicated on relevant plates (yellow arrow shaped plates): check the documentation supplied to identify proper
lifting points. The unit must be lifted by harnessing it as shown in the below figure: use long enough ropes or belts, and
spacer bars so as not to damage the sides and lid of the unit.
Alternatively, units can be lifted using a forklift by inserting the lifting forks into the support pallet (see figure 1)
