Hydraulic connection
A safety valve must be added by the installer to the coolant circuit (hydraulic circuit).
The regulations require the installer, on the coolant network, to set up a degassing safety device
appropriate for the R290 (propane). The goal is to prevent R290 from entering or spreading in a
public or confined space or otherwise.
Use flexible couplings (adapted to the operating system) to reduce vibration transmission.
Thermally insulate the piping to reduce the condensation and heat loss.
Insulation must be implemented continuously to avoid any thermal bridge that can generate problems of
condensation and corrosion.
The thickness and insulating materials must be selected according to location, installation, operating
temperature and maximum ambient temperature to avoid any risk of condensation,
Depending on the installation circumstances, mechanical protection, anti UV or wind protection (for
example) is recommended.
When filling with glycolated water and before operating the pump, it is necessary to purge air from the
system. Use different steam traps available in the chiller hydraulic system. The complete installation must
be designed, built and fitted with air purge points at the highest point of the circuit. (See Section 4
Commissioning).
