Frequently Asked Questions - MMK-AP0153H TOSHIBA

Is the Toshiba MMK-AP0153H compatible with all outdoor units?

No. The MMK-AP0153H is a wall-mounted indoor unit designed for Toshiba VRF multi-split systems (SMMS and SMMSi ranges). It must be connected to a compatible Toshiba outdoor unit by a qualified installer. It is not intended to operate in a traditional single-split setup.

What is the cooling and heating capacity of this device?

The MMK-AP0153H delivers 4.5 kW in cooling and 5 kW in heating. These capacities make it suitable for rooms of about 40 to 45 m2 with standard ceiling height.

What refrigerant does the MMK-AP0153H use?

This device uses R410A, an HFC refrigerant with no impact on the ozone layer. The pressure of this fluid is about 1.6 times higher than that of R22: specific R410A tools are required during installation or maintenance.

At what height should the indoor unit be installed?

The top of the unit should be at least 2 m above the floor. You should also provide a clearance of 850 mm above the device and 170 mm on the sides to ensure air circulation and facilitate maintenance.

In how many directions can the piping be routed?

The piping can be routed in 6 directions: right, left, rear right, rear left, bottom right, bottom left. This flexibility greatly simplifies installation in various room configurations.

Is the wireless remote control included with the device?

Yes. The MMK-AP0153H comes with a wireless remote control, a wall mount for the remote, and two batteries (R03 / AAA). The reception range is about 7 m in axial. Avoid placing the remote near a fluorescent light source or heat.

Is the air filter easily accessible?

Yes. The filter is accessible through the front air intake grille that opens upward without tools. It is recommended to clean the filter regularly (every 2 weeks in intensive use) with warm water and let it dry before replacing it.

The remote control is not working, what should I do?

First, check the condition of the batteries (type R03/AAA) and replace them if necessary. Ensure there is no obstacle between the remote and the unit's IR receiver, and that you are not more than 7 m away. Inverter-type fluorescent lights and direct sunlight can interfere with reception.

Can this device be installed in a kitchen or an area highly exposed to oil?

Installation is not recommended in a restaurant kitchen or near industrial machines using a lot of oil. Greasy vapors can clog the heat exchanger, reduce performance, and damage resin parts. Prefer installation in a clean and well-ventilated space.

What does VRF mean and how is it different from a standard split system?

VRF (Variable Refrigerant Flow) refers to a technology where several indoor units like the MMK-AP0153H are connected to a single powerful outdoor unit, with a variable refrigerant flow. Unlike a simple split system, a VRF system allows air conditioning of multiple zones independently and offers better energy efficiency on a large scale.

What precautions should be taken in case of a refrigerant leak?

In the event of an R410A leak, immediately ventilate the area and keep away from any flame. Contact a certified technician: handling refrigerant is regulated and reserved for qualified professionals. Never attempt to refill the circuit yourself.

What is the maximum recommended area for this model?

The MMK-AP0153H is sized for an area of about 45 m2 under standard conditions (adequate insulation, ceiling height of approximately 2.5 m). For poorly insulated rooms or those with large glass surfaces, it is advisable to request a thermal assessment.

• After the installation work, perform a trial operation (test run) to check for any problem. Follow the Owner's Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner's Manual.

WARNING

• Ask an authorized dealer or qualified installation professional to install (including moving)/ maintain the air conditioner.

Inappropriate installation may result in water leakage, electric shock or fire.

• Be sure to connect earth wire. (grounding work)

Incomplete grounding cause an electric shock.

Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.

• Turn off the main power supply switch or breaker before attempting any electrical work.

Make sure all power switches are off. Failure to do so may cause electric shock.

• Install the refrigerant pipe securely during the installation work before operating the air conditioner.

If the air conditioner is operated with the valve open and without the refrigerant pipe, the compressor sucks air and the refrigeration cycle is over pressurized, which may cause a burst or injury.

• When moving the air conditioner for the installation into another place, be very careful not to enter any gaseous matter other than the specified refrigerant into the refrigeration cycle.

If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally high and it resultingly causes pipe burst and injuries on persons.

• Perform installation work properly according to the Installation Manual.

Inappropriate installation may result in water leakage, electric shock or fire.

• When the air conditioner is installed in a small room, provide appropriate measures to ensure that the concentration of refrigerant leakage occur in the room does not exceed the critical level.

• Install the air conditioner securely in a location where the base can sustain the weight adequately.

• Perform the specified installation work to guard against an earthquake.

If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.

• If refrigerant gas has leaked during the installation work, ventilate the room immediately.

If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.

• After the installation work, confirm that refrigerant gas does not leak.

If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas might generate.

• Electrical work must be performed by a qualified electrician in accordance with the Installation Manual. Make sure the air conditioner uses an exclusive power supply.

An insufficient power supply capacity or inappropriate installation may cause fire.

• Use the specified wires for wiring connect the terminals securely fix.

To prevent external forces applied to the terminals from affecting the terminals.

• Conform to the regulations of the local electric company when wiring the power supply.

Inappropriate grounding may cause electric shock.

• For the refrigerant recovery work (collection of refrigerant from the pipe to the compressor), stop the compressor before disconnecting the refrigerant pipe.

If the refrigerant pipe is disconnected while the compressor is working with the valve open, the compressor sucks air and the refrigeration cycle is over pressurized, which may cause a burst or injury.

15.9	19.7

• In case of flaring for R410A with the conventional flare tool, pull it out approx.

0.5 mm more than that for R22 to adjust to the specified flare size.

The copper pipe gauge is useful for adjusting projection margin size.

Tightening connection

CAUTION

• Do not apply excessive torque. Otherwise, the nut may crack depending on the conditions.

(Unit:N·m)

Outer dia. of copper pipe	Tightening torque
6.4 mm (dia.)	14 to 18 (1.4 to 1.8 kgf*m)
9.5 mm (dia.)	33 to 42 (3.3 to 4.2 kgf*m)
12.7 mm (dia.)	50 to 62 (5.0 to 6.2 kgf*m)
15.9 mm (dia.)	68 to 82 (6.8 to 8.2 kgf*m)

Tightening torque of flare pipe connections

Pressure of R410A is higher than that of R22.

(Approx. 1.6 times) Therefore, using a torque wrench, tighten the flare pipe connecting sections which connect the indoor and outdoor units of the specified tightening torque.

Incorrect connections may cause not only a gas leak, but also a trouble of the refrigeration cycle.

Align the centres of the connecting pipes and tighten the flare nut as far as possible with your fingers. Then tighten the nut with a spanner and torque wrench as shown in the figure.

Work using double spanner

REQUIREMENT

Tightening with an excessive torque may crack the nut depending on installation conditions.

Check of Concentration Limit

The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its concentration will not exceed a set limit.

The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of floor space, individual control, energy conservation by curtailing heat and carrying power etc. Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur).

In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device.

The concentration is as given below.

Total amount of refrigerant (kg)

Min. volume of the indoor unit installed room (^3) ≤ Concentration limit (kg/m)

The concentration limit of R410A which is used in multi air conditioners is 0.3kg / m^3

NOTE 1

If there are 2 or more refrigerating systems in a single refrigerating device, the amounts of refrigerant should be as charged in each independent device.

For the amount of charge in this example: The possible amount of leaked refrigerant gas in rooms A, B and C is 10kg The possible amount of leaked refrigerant gas in rooms D, E and F is 15kg

NOTE 2

The standards for minimum room volume are as follows.

(1) No partition (shaded portion)

(2) When there is an effective opening with the adjacent room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15% or larger than the respective floor spaces at the top or bottom of the door).

(3) If an indoor unit is installed in each partitioned room and the refrigerant piping is interconnected, the smallest room of course becomes the object. But when a mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.

NOTE 3

The minimum indoor floor area compared with the amount of refrigerant is roughly as follows: (When the ceiling is 2.7m high)

CONFIRMATION OF INDOOR UNIT SETUP
