3TEST RUN

[1]Before Test Run

(1) Check points before test run

1

Neither refrigerant leak nor loose power source/ transmission lines should be found.

 

 

2

Confirm that the resistance between the power source terminal block and the ground exceeds 2MΩ by measur-

 

ing it with a DC 500 V megger. Do not run if it is lower than 2MΩ .

 

Note: Never apply the megger to the MAIN board. If applied, the MAIN board will be broken.

3Confirm that the Ball valve at gas and liquid, oil balance sides are fully opened. Note: Certainly close the cap.

4Be sure that the crankcase heater has been powered by turning the main power source on at least 12 hours before starting the test run. The shorter powering time causes compressor trouble.

5If any of the power supply wires (L1, L2, L3, N, .) are mistakenly connected, it is possible to damage the unit. Please exercise caution.

6A transmission booster (RP) is required when the number of connected indoor unit models in a cooling system exceeds the number of models specified in the chart below.

Note: The maximum number of units that can be controlled is determined by the indoor unit model, the type of remote controller and their capabilities.

 

Remote controller type

Remote controller PAR-F 25MA

(*1)

 

 

 

Capability of the

Number of connected indoor units that

Prior to Ver. E

After Ver. F

connected indoor units

can be connected without a RP.

 

 

 

200 or lower

16 (32)

20 (40)

 

200 or higher

16 (32)

16 (32)

The number of indoor units and the total number of remote controllers is displayed within the parenthesis ( ).

(*1) If even one unit that is higher than 200 exists in the cooling system, the maximum capacity will be “200 or higher”.

*Please refer to the installation manual for more details.

*Before turning power on to the outdoor unit, first turn on the transmission booster. (If the outdoor unit are mistakenly turned on first, turn on the transmission booster and then reset the outdoor unit power.)

(2) Caution at inverter check

Because the inverter power portion in outdoor unit electrical part box have a lot of high voltage portion, be sure to follow the instructions shown below.

1During energizing power source, never touch inverter power portion because high voltage (approx. 580 V) is applied to inverter power portion.

2When checking,

1Shut off main power source, and check it with tester, etc.

2Allow 10 minutes after shutting off main power source.

3Open the MAIN board mounting panel, and check whether voltage of both ends of electrolytic capacitor is 20 V or less.

PURY-P400, P500YMF-C specifications

Mitsubishi Electronics has long been a leader in the HVAC industry, known for its innovative technology and reliable performance. Among its notable offerings are the P500YMF-C and PURY-P400 models, designed to address the diverse needs of commercial and residential applications.

The Mitsubishi P500YMF-C is a high-performance outdoor unit that showcases energy efficiency and advanced refrigerant technology. It employs a sophisticated inverter-driven compressor, which optimizes energy usage by adjusting its speed based on the specific heating and cooling demands of the environment. This flexibility helps to minimize energy consumption while ensuring optimal comfort.

One of the standout features of the P500YMF-C is its ability to provide consistent heating and cooling even in extreme outdoor temperatures. The unit can operate effectively in low-temperature conditions, making it ideal for regions with harsh winters. Furthermore, the system is designed with a robust build, ensuring durability and longevity.

On the other hand, the PURY-P400 is an indoor multi-split system that complements the outdoor unit perfectly. It's designed for versatility and efficiency, capable of accommodating multiple indoor units connected to a single outdoor unit. This feature is particularly beneficial for larger spaces or buildings where different zones require individual climate control.

The PURY-P400 incorporates Mitsubishi's advanced filtration technology, which significantly improves indoor air quality. It features a multi-layer filtration system that effectively removes dust, allergens, and other particulates from the air, ensuring a healthier environment for occupants.

Both systems utilize R-32 refrigerant, which has a lower global warming potential compared to traditional refrigerants. This not only makes them more eco-friendly but also complies with emerging environmental regulations. The ease of installation and operation of these units is another noteworthy characteristic, with intuitive controls and user-friendly interfaces that facilitate seamless integration into existing systems.

In summary, the Mitsubishi P500YMF-C and PURY-P400 represent a fusion of technology, efficiency, and user-centric design. With a range of features aimed at enhancing performance and environmental sustainability, these models are an excellent choice for anyone looking to invest in a reliable and efficient HVAC system. Whether for residential or commercial use, Mitsubishi’s offerings continue to set the standard in comfort and efficiency.
