OPERATION
CAUTION:
To avoid fouled machinery, extensive unit clean up, and void warranty, do not operate units
without air filters in place, and do not operate units during the construction process.
The BULLDOG Heat Pump provides year round cooling and heating as controlled by the unit
thermostat or by a direct digital controller.
The BULLDOG Heat Pump provides cooling with a water-cooled refrigeration circuit, and
provides heating using a Hydronic coil. The compressor operates in the cooling mode only and
shuts down during the heating mode providing for quieter operation, extended compressor
life, and a reduction in energy consumption.
