I Operation - Zodiac Z950 Instructions For Installation And Use Manual

3.3 I Operation

3.3.1 Starting up the appliance
• Check that there are no tools or other foreign objects in the appliance,
• Refit the panel providing access to the technical part (see § "1.3 I Dimensions and marking"),
• Set the valves as follows: valve B wide open, valves A, C, D and E closed.
• An incorrect by-pass setting may cause the heat pump to malfunction.
• Check that the hydraulic connections are correctly tightened and that there are no leaks.
• Check that the appliance is stable.
• Turn on the water flow (by activating filtration).
• Close valve B gradually so that the filter pressure is increased by 150g (0.150 bars).
• Open valves A, C and D fully then valve E by half (the air which has built up in the heat pump condenser and the
filtration circuit will bleed out). If valves D and E are not present, open valve A wide and close valve C by half.
• Connect the power supply to the heat pump.
• Power up the device by connecting the external general switch to the appliance. Once the appliance is connected,
check the phase currents.
• The appliance is fitted with a crankcase heater: it must be powered for at least one hour
before it is switched on so that the compressor oil reaches optimal operating condition and
can lubricate the components that it contains.
• Press to switch the appliance on.
• Check the currents of the electric motors, ensuring that they do not exceed the specified
values.
• Check the gas load (high and low pressure gauges must be installed in the cooling circuit).
3.3.2 Configuring the setpoint

• Press to exit the temperature setting mode.
• The setpoint temperature is displayed on the screen:
After the start-up steps for your heat pump:
• Shut down the water circulation temporarily (by stopping the filtration or closing valve B or C) to check that your
appliance stops after a few seconds (via the activation of the flow switch).
• Reduce the temperature setpoint to below the water temperature to check that the heat pump stops operating.
• Switch off the heat pump by pressing
