What pressure in the condenser will cause the condenser fan motors to start?
The condenser fan motor will start when the pressure in the condenser reaches between 190 to 200 PSI fan speed control motor will start modulating. What is the factory setting for the water-regulating valve? Standard factory setting is between 215 and 250 PSI discharge pressure. What is the GPM requirement for my Data Aire chilled water unit? Chilled water equipment can have varying water flows, but a reasonable rule of thumb would be 2.5 GPM per ton. Under typical operating conditions, such as 72 degrees with 45 degree entering water temperature (EWT), this will yield a water temperature differential of about 10 degrees (LWT equals 55 degrees) For instance, model DACU 1834 is a nominal 18 ton unit so a water flow of 2.5 x 18 equals 45 GPM, can be calculated. What is the factory setting of the thermal expansion valve (TXV)? The factory setting for the TXV valve is the mid-range of the valve adjustment stem. The table below shows the settings per valve model. The model number is stamped
