Users and applications
Proheat II Indoor is intended for large facilities where the heat pump should not be visible outside or where there is no space for an outdoor unit. It is installed in the plant room of hotel and large facility pools. The airflow is directed outside the building through a centrifugal fan and a duct connection. The model is selected for the winter demand by looking at the heating output at 5°C air. Operating values are read on the digital display.
- Pools of hotels and large facilities with a plant room
- Urban facilities without space for an outdoor unit
- Large residential complex pools with a basement plant room
- Pools with a 400 V three-phase supply needing more than 43.6 kW of heat

// 04 · Maintenance
Maintenance checkpoints
On an enclosed unit, maintenance focuses on keeping the air path open. The duct opening and coil are cleared of dust, and it is checked that the fan turns freely. The pH and hardness of the pool water are kept in balance. Operating values are monitored on the digital display or through the remote connection. The R410A circuit is opened only by an authorised service.
- The duct opening and coil are cleared of dust.
- The water inlet and outlet connections are checked for leaks.
- Operating values are monitored on the display or through the remote connection.
- Only an authorised service works on the R410A circuit.

+90 216 475 39 37A ducted heat pump is installed in an enclosed space; AstralPool Proheat II Indoor comes with a centrifugal fan for this purpose. The fan carries the air outside the building through a duct. Without a duct, the unit draws back the air it has cooled and the heating output falls. The duct section and length are calculated in the installation project.

At 25°C air and 26°C water, Proheat II Indoor delivers 43.6 kW to 125.5 kW of heating. At 15°C air this range becomes 34.9 kW to 114.9 kW, and at 5°C air 27.4 kW to 90.3 kW. The model is selected according to the demand of the facility in its coldest operating month.

The step names and the 0°C lower limit are the same in both families. Proheat II Indoor is installed in a plant room with a duct-connected centrifugal fan; its noise level is between 59.2 dBA and 61.5 dBA. On AstralPool Proheat II Standard/Chiller the noise is between 66.2 dBA and 72.5 dBA, and a Chiller version with cooling is available. At 25°C air, Indoor-35 delivers 43.6 kW and Standard 35 delivers 36.2 kW.

Proheat II Indoor requires a 400 V, 3 phase, 50 Hz supply. The rated current is between 14.6 A and 45.6 A, and the maximum current between 23.9 A and 81.4 A. The cable section is given separately for each model and increases markedly on the larger models. The panel and fuse are selected according to the maximum current.
Çilek Havuz Corporate
The recommended water flow is 12-15 m³/h on Indoor-35, 25-35 m³/h on Indoor-60 and 50-70 m³/h on Indoor-120. It is checked during commissioning that the filtration pump provides this range. If necessary, a by-pass is installed in the line. The connection diameter is 63 mm on the smaller models and 75 mm on models 90 and 120.
Çilek Havuz Corporate
Proheat II Indoor is compatible with remote connection (Fluidra Connect), and its operating values are monitored remotely. The digital display of the unit shows the same values in the plant room. In a facility with more than one pool, the unit is monitored without going down to the plant room. The network and equipment needed for the connection are planned separately during installation.
Çilek Havuz Corporate
The refrigerant is R410A. The refrigerant charge is 6 kg on Indoor-35, 9 kg on Indoor-45, 12 kg on Indoor-60, 2 x 7 kg on Indoor-90 and 2 x 9 kg on Indoor-120. The first three models have one fan, the last two models two fans. The heat exchanger is G2 titanium and the casing magnesium-coated aluminium.
