Drain; Filling And Discharge Circuits; Filling The Production Circuit (Heating, Cooling, Dhw And Pool) - ECOFOREST ecoGEO Serie Manual De Instalador

In addition to the option mentioned above, in ecoGEO Basic models with an HTR system, pool production can be connected to the
DHW circuit. This allows two options: exclusive pool production with the primary condenser and simultaneous heating / cooling
and pool production through the HTR system.

3.6. Drain

Condensation may occur one certain internal heat pump components during normal operation. On the other hand, antifreeze
mixture or water may spill from the heat pump's internal safety valves due to eventual circuit overpressure.
There is a drain connection at the rear of the heat pump to evacuate these liquids.

4. Filling and discharge circuits


During filling work on the hydraulic circuits, take special care to prevent liquid from spilling on the
internal electrical heat pump components, which could cause personal injury due to electrocution

and/or poor equipment operation.

4.1. Filling the production circuit (heating, cooling, DHW and pool)

The heat pump is equipped with internal filling / discharge valves for the production circuit. It is recommended to use these valves
to ensure that the internal circuits are completely bled. Take the following steps to fill the circuit.
1. Open all the valves of the production circuits.
2. Fill the circuit through the filling valve until the target pressure is reached. Make sure that the pressure does not exceed 3
bar (pressure gauge) under any circumstance.
