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.
FOR HEAT PUMP UNITS, IN PARTICULARLY COLD CLIMATES, INSTALLATION ON ELEVATION SUPPORTS IS RECOMMENDED TO ALLOW ICE TO
FORM UNDER THE UNIT WITHOUT DAMAGING IT.
Any condensation that may leak from the plumbing pipes remains on the base of the unit and dries naturally. As the pipes are well insulated,
condensation production is minimal and therefore there is no need to install drainage systems.
CAUTION: for heat pump units, in the event that the prepared ducting system is not used, a limited amount of water (possi-
ble ice in the winter period) from the condensate drainage system may be deposited in the vicinity of the unit, with conse-
quent danger of slipping/falling.
5.8.4 Filling / Discharge of the plant
CAUTION: Supervise all filling/top-up operations.
CAUTION: Before filling/topping up the system disconnect power to the units.
CAUTION: The system must always be filled/topped up in controlled pressure conditions (1÷3 bar). Make sure that a pres-
sure reducer and safety valve have been installed on the filling/top-up line.
CAUTION: The water on the filling/top-up line must be appropriately pre-filtered from any impurities and suspended parti-
cles. Make sure that a removable cartridge filter and dirt separator are installed on the line.
CAUTION: Regularly check and vent the air built up in the system.
CAUTION: Install an automatic air venting valve at the highest point of the system.
