2.12 Fire detection thermostat
As standard, the unit is fitted with an air supply probe that stops at 80 °C and switches to "lock out" mode,
in which case the control must be manually reset.
Using this option, a set temperature probe and manual reset are located in the unit supply area. If the
selected temperature is reached in this area, the unit stops and switches to "lock out" mode, in which
case where the probe and control must be manually reset before it can be restarted.

This includes all of the hydraulic and control components required for operating, such as the 0-10 V
proportional actuator mixer valve and the antifreeze probe.
2.14 Heating element
Available for ARC cold-only models and the ARH heat pump at powers of 37, 50 and 60 kW.
The power supply to the heating resistor must be independent to the general power supply to the unit
and must be fitted with its own circuit breaker (not supplied). See sections
ARC / ARH units with auxiliary
heating element

use for maintenance purposes.
2.16 Anti-vibration kit
This is formed by the shock absorbers and the necessary nuts and bolts for on-site assembly when fitting
the unit.
2.17 Copper fin coils
Copper fin coils to give the best corrosion protection for installations in coastal areas, maintaining full
efficiency. This is applied to the condensers (outdoor units) and evaporators (indoor units). See section
Weight options and accessories
, see on page 8 for the increase in weight in relation to standard.
2.18 Roofcurb mounting base, fixed type
For installation on flat and levelled building roofs.
Structure made of galvanised sheet steel supplied in kit form for on-site assembly and installation.
Allows for installation of the ducts directly from inside the building following fitting of the rooftop unit and
