1.2.1 - Installation safety considerations
After the unit has been received, and before it is
started up, it must be inspected for damage. Check
that the refrigerant circuits are intact, especially
that no components or pipes have shifted or been
damaged (e.g. following a shock). If in doubt, carry
out a leak tightness check. If damage is detected
upon receipt and before signature, immediately
le a claim with the shipping company.
In case of damage, carry out a leak detection test
before removing the cardboard box.
The unit must be stored outside or in a controled
environment (R290 sensors and non ignition
source area).
The units can not be stacked.
The unit must be installed outdoors following
clearance from §1.4.2. A minimum distance of one
meter around the unit must be cleared of any
obstacles for safe use.
This appliance can be used by children aged from
8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of
experience and knowledge if they have been given
supervision or instruction concerning use of the
appliance in a safe way and understand the
hazards involved.
Children shall not play with the appliance.
Cleaning and user maintenance shall not be made
by children without supervision.
Do not remove the pallet or the packaging
until the unit is in its nal position. These units
can be moved with a fork lift truck, as long as
the forks are positioned in the right place and
direction on the unit see gure 3.
The units can also be lifted with slings (refer to
Figure 1 and 2).
Use slings with the correct capacity, and
always follow the lifting instructions on the
certied drawings supplied for the unit.
The coil of this unit can reach a temperature
above 50 °C and can present a burn risk.
The water pipings can also reach temperatures
up to 75 °C and be a source of burn if touched.
Safety is only guaranteed, if these instructions
are carefully followed. If this is not the case,
there is a risk of material deterioration and
injuries to personnel.
DO NOT COVER ANY PROTECTION DEVICES.
This applies to relief valves and rupture disks
in the refrigerant or heat transfer medium
circuits. Check if the original protection plugs
are still present at the valve outlets. These
plugs are generally made of plastic and
should not be used. If they are still present,
please remove them. Install devices at the
valve outlets or drain piping that prevent the
penetration of foreign bodies (dust, building
debris, etc.) and atmospheric agents (water
can form rust or ice).
These devices, as well as the drain piping,
must not impair operation and not lead to a
pressure drop that is higher than 10% of the
control pressure.
Control
When the unit is subjected to re, the uid may
then be decomposed into toxic residues when
subjected to the ame :
■Stay away from the unit as far as possible.
■Set up warnings and recommendations for
personnel in charge to stop the re.
■Make sure to precise that the unit contain
propane refrigerant as well as lubricant oil.
■Fire extinguishers appropriate to the system
and the refrigerant type must be easily
accessible.
All precautions concerning handling of
refrigerant must be observed in accordance
with local regulations.
Accumulation of refrigerant in an enclosed
space can displace oxygen and cause
asphyxiation or explosions.
