Product description

Dressed in a sleek-looking casing, the Poolex SilentJet Fi 120 flaunts its cutting edge technologies right next to your swimming pool, the rear air propulsion system and Full Inverter technology make these heat pumps ultra silent.

Full Inverter technology translates into significant energy savings of up to 35% compared to an on/off heat pump. This is enabled through functionalities such as soft-start and an operating speed which continuously adapts itself according to the pool set temperature.

Thanks to its rear ventilation, the SilentJet Fi runs at an unrivalled level of silence, noise is reduced to as little as 20 dB(A) at 10 metres.

Manage your SilentJet Fi remotely via built-in Wi-Fi which connects to your iPhone or Android smartphone using the Poolex app.

The SilentJet Fi 120 is 230v single phase unit and will require electrical installation by a qualified electrician, continuous running and soft start avoids peaks in consumption.

What is COP?

COP stands for Coefficient of Performance

COP is quoted as a number, such as 16.6

For each kW of energy input, 16.6 x kW would be output

The higher the output, the lower the running costs

Installation

Heat loss

If you are thinking of heating your pool you should cover the pool when not in use as 80% of heat loss occurs through surface evaporation, a separate solar or bubble cover is a worthwhile investment if you don’t have an existing cover.

With an above ground pool it is especially important to keep it covered as these pools are not well insulated against heat loss – additional insulation around the sides and bottom of an above-ground pool can help to retain valuable heat – in fact properly insulating your pool can extend your season or even reduce the size of heat pump required.

All heat pumps in the range will require electrical installation by a qualified electrician, the use of a separate MCB (Miniature Circuit Breaker, slow type, C or D curve) is recommended. Full installation guidelines can be found in the user manual including the required fuse rating and cable size.

The electrical connection marked water pump should not to be used for connecting your pump if using a sand filter as flow protection on the heat pump will switch the power off preventing backwash operation (flow is reversed during backwashing).

Water inlet and outlet connections are 1½ inch / 50mm across the range.

If the flow rate through your heat pump is too high it can take longer to heat your pool or you may struggle to achieve your desired temperature, our bypass kit for above ground pools optimises the flow rate to maximise the heat transfer to your pool water. A bypass kit also allows the circulation and filtering of pool water without heating and for winterising your heat pump.

The SilentJet Fi features built-in Wi-Fi connectivity as standard (requires Wi-Fi network with suitable signal strength) and can be controlled from your smartphone. The ‘Poolex’ App is available for both iOS and Android smartphones.

The App can be used to view the current pool water temperature, adjust the desired temperature, switch between heating and cooling modes, set the timer and turn the heat pump on and off remotely.

Your SilentJet Fi swimming pool heat pump should always be installed outside, the aluminium case provides necessary protection from the weather, the provided isothermal winter cover can be used to cover the unit when not in use.

The manufacturer literature may state that the heat pump should be positioned above the waterline, the assumption being that pools are in-ground, therefore the heat pump would sit at ground level.

If you have an above-ground pool please position your heat pump at ground level (therefore below the waterline), there is no need to elevate the heat pump.
