1 VAC System Simplicity Mitsubishi Electric Cooling and Heating of 1 6/27/2013 5:02 PM System Simplicity Design, Install, Maintain Design The system allows for design flexibility, from the simplest to the most complex. It also provides for ducted or ductless systems, including virtually any application (or a variety of applications) within a single building. With the wide range of products available in our combined Mr. Slim and CITY MULTI product lines, your design can connect 1 to 50 indoor units to a single outdoor unit. Many products use T-branches and headers for the ultimate in piping design flexibility. Modular systems with a variety of indoor and outdoor units can be put together for a system that is just right for your needs. Condensing Units (heat recovery, heat pump and water-sourced) offer vertical air discharge that allows units to be installed side-by-side in a single area, saving space and resources. They also offer long line lengths - up to 2,624 feet on R2 Series and 3,280 on Y-series (one way). Additionally, you don't need space for compressor farms because the mechanical chases take up very little space. Indoor units meet your design and space needs - ducted or ductless, ceiling, floor, wall or vertical. Install Installation includes simple two-pipe systems with easy, non-polar, two-wire control connections. This means less labor and fewer materials as well as quicker, easier installation. Copper refrigerant piping is smaller and lighter than ductwork or Schedule 40 steel water pipes, so the modular outdoor unit's compact design also simplifies transportation. Maintain / Service Many other systems require retro-commissioning and constant maintenance to preserve their installed efficiency, but VRF technology has all the logic built in. System performance is constantly modified to maximize performance and comfort. System tests are available to check wiring, sensor and the refrigerant levels. Normal maintenance consists of changing filters and cleaning coils. Many systems allow an indoor unit to be serviced while other indoor units within the same piping system are still in operation. VRF technology also allows for lower maintenance costs than water-cooled chillers since water treatment issues are avoided.

Ask authorized people to clean the filter. When resetting "FILTER" display When the [FILTER] button is pressed two times successively after cleaning the filter, the display goes off and is reset. Note: When two or more different types of indoor unit are controlled, the cleaning period differs with the type of filter. When the master unit cleaning period arrives, "FILTER" is displayed. When the filter display goes off, the cumulative time is reset. " FILTER" indicates the cleaning period when the air conditioner was used under general indoor air conditions by criteria time. Since the degree of dirtiness depends on the environmental conditions, clean the filter accordingly. The filter cleaning period cumulative time differs with the model. This indication is not available for wireless remote controller. Cleaning the filters Clean the filters using a vacuum cleaner. If you do not have a vacuum cleaner, tap the filters against a solid object to knock off dirt and dust. If the filters are especially dirty, wash them in lukewarm water. Take care to rinse off any detergent thoroughly and allow the filters to dry completely before putting them back into the unit ~ Caution: Do not dry the filters in direct sunlight or by using a heat source, such as an electric heater: this may warp them. Do not wash the filters in hot water (above 122 of), as this may warp them. Make sure that the air filters are always installed. Operating the unit without air filters can cause malfunction. Before you start cleaning, stop operation and turn OFF the power supply. Indoor units are equipped with filters to remove the dust of sucked-in air. Clean the filters using the methods shown in the followinqi sketches. Filter removal ~ Caution: In removing the filter, precautions must be taken to protect your eyes from dust. Also, if you have to climb up on a stool to do the job, be careful not to fall. When the filter is removed, do not touch the metallic parts inside the indoor unit, otherwise injury may result. PLFY-P NAMU-E, PLFY-P NCMU-E (j) Pull both the bottom corners of the intake grille to open the grille, then lift the filter. PKFY-P NFMU-E (j) Hold the filler lug (located at the bottom of the intake grille) and pull it To reinstall the filters, push the filter lug upward. PCFY-P NGMU-E (j) Open the intake grille. Hold the knob on the filter then pull the filter up in the direction of an arrow. To replace the filter after cleaning, be sure to insert the filter far enough until it fits into Intake Grille PMFY-P NBMU-E (j) Pull the knob on the intake grille in the direction indicated by the arrow and it should open. Open the intake grille. Release the knob on the center edge of the intake grille and pull the filter forward to remove the filter. <N Knob Grille Intake orille Filter (j) Pressing the PUSH button on the outer side of the intake grille causes the intake grille to open. A filter with an intake grille on it can be removed by pulling the filter forward.
