3. Heat Pump checks
Flare Nuts
Ensure the flare nuts are tight, use two spanners and apply pressure, one spanner countering
the force of the other.
Compressor Sitting Squarely
This image shows the Heat
Pump without the casing
revealing the compressor.
Note the compressor sits in a
tray under its own weight and
can occasionally shift its
alignment during transit and/or
installation.
If there is any metallic vibrating
or rattling sound present, try
shifting the compressor with
your hands to ensure it squarely
seated in the tray.
III¡Technical Guide
1. Starting Current and Peak Current
When the Heat Pump starts up for the first time, when the tank has cold water, the power
input will be approximately 700 watts / 220 volts = 3.1 amps. The current will gradually
rise over the heating cycle until it reaches the maximum power input of 1.38kW/230
volts = 6.2 amps, just before the thermostat cuts out the Heat Pump compressor. The
power input ranges between 0.8kw to 1.38kW, 1.1kW average, and will produce Heat
Output of 3.3kW at 20 deg C and 4.4kW at 30 deg C ambient temperature at lower humidity.
