Some of the benefits of the Carrier MPH Series multi-zone system include:
Fast Installation: This compact ductless system is simple to install. A mounting bracket is included with the indoor units and only wires and piping need to run between the indoor and outdoor units. These units are fast and easy to install ensuring minimal disruption to customers in homes or the workplace. This makes the 38MAR systems the equipment of choice for retrofit applications.
Simple Servicing and Maintenance: Removing the top panel on outdoor units provides immediate access to the control compartment, providing a service technician access to check unit operation. In addition, the draw-thru design of the outdoor section means that dirt accumulates on the outside surface of the coil. Coils can be cleaned quickly from the inside using a pressure hose and detergent. On all indoor units, service and maintenance expense is reduced due to easy-to-use cleanable filters. In addition, these high wall systems have extensive self-diagnostics to assist in troubleshooting
Built−in Reliability: Ductless system indoor and outdoor units are designed to provide years of trouble−free operation.
The high wall indoor units include protection against freeze-up and high evaporator temperatures on heat pumps.
The condensing units on heat pumps are protected by a three minute time delay before the compressor starts the over-current protection and the high temperature protection.
Easy−To−Use Controls: The multi−zone systems have microprocessor−based controls to provide the ultimate in comfort and efficiency. The user friendly wired and wireless remote controls provide the interface between the user and the unit.
