Operational Expectations 

 

The BULLDOG KlassKepper Heat Pump is designed to provide reliable heating and cooling right out of the 
box. However, transportation and handling damage, service valve leakage, or system problems may cause 
less than optimum operation. In the event that the qualified commissioning agents suspect there is an 
operational problem with the heat pump, they need to inform the factory immediately for direction. In 
certain instances, the factory may request a manifold refrigeration gauge be attached to the heat pump 
along with thermo-couples to determine the operating parameters of high and low pressure, and super 
heat and sub cooling. Based on this information the factory may request the charge be adjusted or the 
refrigeration components be adjusted to optimize cooling operation.
