OPERATION (Detailed)
CAUTION:
To avoid fouled machinery, extensive unit clean up, and to maintain 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.
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.
To ensure correct operation, centralized equipment located within the building mechanical room is
automatically controlled to provide each heat pump unit with water that is at the appropriate
temperature and flow rate.
