Each unit is pressurized with a holding charge of refrigerant R-410A for storage and/or shipping. The compact design, clean styling, small footprint, and quiet operation make these condensing units and heat pumps suitable for almost any outdoor location. On rooftops... because they weigh much less than a single package unit of similar capacity and are much easier to rig and support. On the ground... because the footprint is compact allowing a variety of applications. Both the UP condensing units

An anti-short cycle delay (ASCD) is utilized to prevent operation of a compressor too soon after its previous run. The ASCD is initiated on unit start-up and on any compressor reset or lockout. The Simplicity™ control board monitors the following inputs for each cooling system: • A high-pressure switch is factory installed to protect against excessive discharge pressure due to a blocked condenser coil or a condenser fan motor failure. During cooling operation, if a high-pressure limit switch o

The equivalent length of the vent system is the total length of straight pipe PLUS the equivalent length of all of the elbows. The following rules must also be followed: 1. Long radius (sweep) elbows are recommended. Standard elbows may be used, but since they have a longer equivalent length, they will reduce the total length of pipe that will be allowed. Short radius (plumbing vent) elbows are not allowed. The standard dimensions of the acceptable elbows are shown below. 2. The maximum equiv
