The PUGH condensing units are Heat Pump models that are designed specifically for use with Mitsubishi Electronics PKH, PCH, and PLH MR. SLIM indoor units of matching nominal capacities. Models from 1.5 through 3.5 tons are available.
•QUALITY CONDENSER COILS - The coil is con- structed of enhanced copper tube and aluminum fins.
•COIL PROTECTION - Coils are protected from dam- age by a polymer mesh applied between the coil face and the PVC coated steel coil guard.
•PROTECTED COMPRESSOR - The compressor is internally protected against high pressure and temper- ature. This is accomplished by the simultaneous oper- ation of high and low pressure switches and a temperature sensor that protects the compressor if undesirable operating conditions occur. A liquid line fil-
•DURABLE FINISH - The cabinet is made of pre- painted steel. The
•LOWER INSTALLED COST - Installation time and costs are reduced by easy power and control wiring connections. Discharge line heat exchanger knock- outs are provided, if required. The unit contains enough refrigerant for matching indoor units and 25 feet of interconnecting piping. The small base dimen- sion means less space is required on the ground or roof.

•TOP DISCHARGE - The warm air from the top mounted fan is blown up away from the structure and any landscaping. This allows compact location on
•ADVANCED CONTROL BOARD - Each unit is equipped with an advanced electronic control board. This board controls the function of the outdoor unit and improves the operation and protection of the unit. The control board also provides operational and diagnostic information to the service technician through multiple LED’s.
•LOW OPERATING SOUND LEVEL - The upward air flow carries the normal operating noise up away from the living area. The rigid top panel effectively isolates any motor sound. Isolator mounted compressor and the rippled fins of the condenser coil muffle the normal fan motor and compressor operating sounds.
•LOW MAINTENANCE - Long life permanently lubri- cated
•EASY SERVICE ACCESS - Fully exposed refrigerant connections, a single panel covering the electrical con- trols and a plug in the control box connecting the con- denser fan, make for easy servicing of the unit.
•SECURED SERVICE VALVES - Secured reusable ser- vice valves are provided on both the liquid and vapor connections for ease of evacuating and charging.
•ETL LISTED - Approved for outdoor application.
•Certified in accordance with the Unitary Small Equip- ment certification program, which is based on ARI Standard 210/240.
