3. HANDLING
3.1 Opening the packaging
• Check that the unit is intact upon delivery and notify the carrier
immediately, in writing, of any damage that may be due to improper or
negligent transport;
• move the unit to the place of installation before removing it from the
packaging, lifting the package with the wooden pallet. Use lifting
equipment, avoid handling the load manually. Residual risk of the unit
falling during installation if an improper hoisting device/accessory is
used;
• position the unit near the place where it is to be installed (still packaged
on the pallet);
• remove the packaging, open the cardboard box and remove the screws
fixing it to the pallet.
It is recommended to store the packaging (cardboard box, pallets and
bolts) in a dry environment so that they can be reused.
3.2 Positioning the unit
The unit must be firmly anchored to the system it is part of using the “L”
shaped anchoring sections on the sides of the structure.
The unit must be positioned so as to allow the following operations:
• opening and removal of the front panels on the refrigerant compartment
and electrical compartment;
• accessibility to the internal parts for checks and maintenance (observe
the clearances);
• connection of the refrigerant supply lines;
• connection of the safety valve outlet to the discharge line;
• connection of the water supply lines;
• power and control electrical connections;
• temperature probe and optional kit connections;
• communication serial line connections.
The unit must be positioned in the immediate vicinity of the single
showcase served (single evaporator unit) or in a favourable position for
correct distribution of the refrigerant to the entire group of showcases
(multi evaporator unit), ensuring both the minimum length of piping
between the unit and the evaporator, and oil return to the unit. To ensure
correct operation of the product, it should be installed on top of the
showcase, on a flat surface, in a suitable position so that the weight of
the unit is supported by the showcase. The showcase must designed to
support the weight of the unit when operating.
HEOS BOX can also be installed on the floor, observing the clearances
and making sure that there is natural ventilation to the unit. Always avoid
positioning/installing the unit:
• outdoors, in a place where it is exposed to the weather;
• in positions where the relative humidity is > 80% and condensing;
• in positions where there the temperature is >40°C (104°F) or <5°C (41°F);
• in positions that may affect the showcase support structure or its other
parts;
• in positions where liquids may be spilled or drip;
• in positions where accidental impact may occur;
• in positions that can obstruct passageways/exit routes or, in general,
interfere with the transit of people.
Caution: the maximum distance between the unit and the showcase
must not exceed 6 m. If the maximum distance is exceeded, appropriate
measures must be taken, such as traps in the refrigerant connections to
ensure oil return to the compressor and at the same time limit the pressure
drop on the refrigerant suction line due to the part of the refrigerant circuit
outside of the unit.
Caution: position the Heos Box in such a way that there is adequate
room for manoeuvre if needing to access disconnect switch QS1
Positioning procedure:
• open the packaging. Check that the unit’s panels are not damaged and
keep the covers closed and secured;
• remove the unit from the pallet only using the brackets on the structure
as lifting points. Always use all four lifting brackets (pos. 2 in Fig. 3.a) to
lift the unit, according to the two possible arrangements shown below.
It is forbidden to lift the unit by hand; residual risk of the unit falling
during installation if an improper hoisting device/accessory is used;
• when lifting, keep the unit in horizontal with the covers closed and
secured. Residual risk of the unit falling during installation if it is lifted
without the covers;
• place the unit in its final position, horizontally, avoiding knocks
and making sure not to deform/damage the refrigerant and water
connections;
• firmly secure the unit using screws through the “L” sections (position
1 in Fig. 3.a) on the structure. It is forbidden to make the refrigerant,
water or electrical connections without first having secured the unit in
its final position; residual risk of the unit falling if installed at a height and
accessed using unsuitable equipment.
