2 SAFETY PRECAUTION

2-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply circuits must be disconnected.

2-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilising refrigerant R410A

Use new refrigerant pipes.

Make sure that the inside and outside of refrige- rant piping is clean and it has no contaminants such as sulfur, oxides, dirt, shaving particles, etc, which are hazards to refrigerant cycle.

In addition, use pipes with specified thickness.

Contamination inside refrigerant piping can cause deterio- ration of refrigerant oil etc.

Store the piping to be used indoors during installation, and keep both ends of the piping sealed until just before brazing. (Leave elbow joints, etc. in their packaging.)

If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of com- pressor.

The refrigerant oil applied to flare and flange connections must be ester oil, ether oil or alkylbenzene oil in a small amount.

If large amount of mineral oil enters, that can cause deterio- ration of refrigerant oil etc.

Use a vacuum pump with a reverse flow check valve.

Vacuum pump oil may flow back into refrigerant cycle and that can cause deterioration of refrigerant oil etc.

Use the following tools specifically designed for use with R410A refrigerant.

The following tools are necessary to use R410A refrigerant.

	Tools for R410A
Gauge manifold		Flare tool
Charge hose		Size adjustment gauge
Gas leak detector		Vacuum pump adaptor
Torque wrench		Electronic refrigerant
		charging scale

Handle tools with care.

If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of com- pressor.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refrigera- nt will change and the efficiency will be lowered.

Charge refrigerant from liquid phase of gas cylinder.

If the refrigerant is charged from gas phase, composition change may occur in refrigerant and the efficiency will be lowered.

Do not use refrigerant other than R410A.

If other refrigerant (R22 etc.) is used, chlorine in refrige- rant can cause deterioration of refrigerant oil etc.

Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released.

Use the specified refrigerant only.

Never use any refrigerant other than that specified. Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.

Correct refrigerant is specified in the manuals and on the spec labels provided with our products.

We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by failure to follow the instructions.

PKA-A36KA4.TH, PKA-A30KA4.TH, PKA-A24KA4.TH specifications

Mitsubishi Electronics introduces its PKA series of commercial air conditioners, comprising models PKA-A24KA4.TH, PKA-A30KA4.TH, and PKA-A36KA4.TH. These units are designed to meet the growing demand for energy-efficient and reliable climate control solutions in commercial spaces. Each model in the series is equipped with advanced features that set them apart in the competitive air conditioning market.

One of the main features of the PKA series is the innovative inverter technology. This technology enables the air conditioning units to adjust their cooling or heating output according to the indoor temperature, leading to significant energy savings. By operating at varying speeds rather than a constant rate, the inverter system provides a more consistent and comfortable environment while reducing energy consumption by up to 30% compared to traditional fixed-speed systems.

Another standout characteristic of the PKA-A24KA4.TH, PKA-A30KA4.TH, and PKA-A36KA4.TH models is their compact design. These units are designed for easy installation in various commercial settings while taking up minimal space. This is particularly beneficial for businesses looking to optimize their floor space without compromising climate control efficiency.

The PKA series features advanced filtration technology, including a highly efficient air purification system. This enhances indoor air quality by removing dust, allergens, and other airborne pollutants, creating a healthier environment for occupants. The inclusion of a self-cleaning function also contributes to maintenance ease, as the unit automatically cleans the heat exchanger, preventing dust buildup and ensuring efficient operation.

Mitsubishi's commitment to whisper-quiet operation is another critical feature of these models. They are engineered to operate at sound levels as low as 19 dB(A), making them ideal for environments where noise control is essential, such as offices, hotels, or healthcare facilities.

Moreover, the PKA series is compatible with Mitsubishi's sophisticated control systems, allowing users to manage their air conditioning remotely via smartphone or tablet. This level of control enhances user convenience and maximizes system efficiency by enabling real-time adjustments based on occupancy and other factors.

Overall, the Mitsubishi Electronics PKA-A24KA4.TH, PKA-A30KA4.TH, and PKA-A36KA4.TH units represent a perfect blend of modern technology and user-centric design, providing businesses with effective, efficient, and quiet climate control solutions. With their advanced features, energy-saving capabilities, and emphasis on air quality, these models stand out as premier choices for managing environmental comfort in commercial applications.
