INVERTER Technology


INVERTER-driven compressor technology gives Mr. Slim systems a higher degree of cooling and heating abilities that outperform and are more energy efficient than conventional systems. Desired room temperature is reached more quickly and maintained more consistently. This eliminates the peaks and valleys of temperature swings that we're used to with older, conventional units.

Flexible Control Options

Convenient and efficient zone control means you can cool or heat only the spaces in use. You can even have single or dual controllers connected to one system. The controller does not even have to be in the space shared with the indoor unit, which measures the room temperature. Features include a larger mode display, weekly timer, temperature range setting, setting lock, auto-off, expanded fault codes, and service call number display.

Advanced Microprocessor Controls

Built-in electronics ensure efficient operation and maximum performance for optimum comfort.

Low Ambient Cooling Down to 0 Degrees Outdoors

This feature is perfect for computer network centers and telecom equipment rooms that need help to stay cool even during winter months.

Environmentally Friendly

Mr. Slim systems use an environmentally friendly refrigerant.

This feature, along with the addition of a low-ambient wind baffle, allows for a space to be air-conditioned even when it is as low as 0 degrees outside. This cooling ability is important when dealing with electronic equipment rooms, telecom substations, surveillance mechanical rooms, restaurant kitchens, fitness centers, and more. Redi-charged Systems P-Series outdoor units come with enough refrigerant to be installed up to 100 feet away from the indoor units. Line sets can be run up to a maximum distance of 100 feet for PUY(Z)12-18 outdoor units and 165 feet for PUY(Z)24-42 outdoor units when additional charge is added. These systems are easier to fit into any space thanks to unique design profiles and R410A refrigerant. R410A is environmentally friendly with zero Ozone Depletion Potential (ODP).

Installation Service and Maintenance

Ease P-Series outdoor units are designed with easy service and maintenance in mind. Maintenance points are located behind easy-access panels, to make installation and service a breeze for a trained technician. Four way piping access allows connection in four directions: front, rear, right, and bottom (all PUY/PUZ models). Using the new A-Control system, just three polarity sensitive wires, plus a ground conductor, run from the outdoor to the indoor unit providing both power and communication connections. Two non-polar wires connect the indoor unit and wall-mounted controller. This wiring design helps avoid installation errors. An optional wireless remote controller kit is available for the P-Series ceiling-mounted indoor units.
