ATTENTION: It is recommended to connect the safety valve vent in an appropriate conveyor / discharge.
Otherwise the discharged water could stagnate around the unit and become a source of danger due to slipping / falling.
5.8.3 Drainage system
The units all of them adopt drainage holes on the basement for the condensate draining which can leach from the pipes of hydraulic and refrig-
erant circuits, and to discharge the generated water during defrosting cycles.
