3. PROTECTIVE SAFETY ZONE
ᘐ WARNING: The product contains the hydrocarbon
refrigerant R290 which is very ammable. The refrigerant
may mix with air to form a ammable atmosphere
increasing the risk of re and/or explosion.
Work that requires the removal of the exterior casing of the
Heat Pump must only be carried out by competent persons
who are familiar with the risks of R290 refrigerant.
Work on the refrigeration circuit must only be carried out
by a Cat I or Cat II F-gas certied engineer with a City and
Guilds 6187-21 certicate or equivalent. Work done on the
heat pump should be done in accordance with industry
standard safety procedures and practices for working with
hydrocarbons.
The refrigerant circuit of the outdoor heat pump is charged
with R290 refrigerant, which is an odourless, colourless, and
accordance with ISO 817 and ANSI/ASHRAE standard 34.
When selecting an installation area, it should be considered that
R290 has a higher density than air and therefore in the event of
leakage from the heat pump, will displace air and pool in low-
to prevent explosive and asphyxiating atmospheres, by avoiding
the following within this area:
1. Building openings, e.g., doors, windows, air intakes,
exhausts, cellar entrances, etc.
2. Ignition sources, e.g., electrical switches, plugs sockets,
drills, heaters, etc.
3. Areas outside of the property lines e.g., public areas,
adjacent buildings.
4. Ditches, troughs, or depressions in the ground.
5. Surfaces exceeding 400°C in temperature.
The protective safety zone is dependent on the installation areas
and adjacent structural installations. See Figure 1, Figure 2 and
Figure 3 to determine the extent of the protective safety zone.
In this area no further works should be carried out which would
zone.
A - Safety Zone
For all shown types of installations, the top of the protective
safety zone is in line with the top face of the heat pump.
ⓘ IMPORTANT: Dimensions shown in See Figure 1, Figure 2
and Figure 3Figure 30 below are the minimum dimensions for
the extent of the protective safety zone.
