When installing your TOSHIBA MMK-UP0301HP-E, please adhere to the following guidelines:

WARNING: Install the air conditioner at a location strong enough to withstand the weight of the unit. If the strength is not enough, the unit may fall down, resulting in injury.

CAUTION:

• Do not install in a location where flammable gas may leak. If gas leaks and accumulates around the unit, it may ignite and cause a fire.

• When an outdoor unit using R32 refrigerant is combined with an indoor unit, pay attention to the floor area in the room. Indoor units cannot be installed in rooms with a floor area less than the minimum floor area. For details, follow the Installation Manual for the outdoor unit.

Upon approval of the customer, install the air conditioner in a place that satisfies the following conditions:

• Place where the unit can be installed horizontally.

• Place where a sufficient servicing space can be ensured for safety maintenance and checks.

• Place where drained water will not cause any problem.

Installation Space Requirements:

• The indoor unit shall be installed at least 2.5 m high.

• Avoid putting anything on top of the indoor unit.

• Keep 50 mm or more for clearance between the top plate of the indoor unit and the ceiling surface.

• Provide a space of 191 mm or more on the left and 170 mm or more on the right for service clearance for the cross flow fan.

• A place where there is no obstacle near the air inlet and outlet.

• A place that allows easy installation of the piping to the outdoor unit.

• A place which allows the front panel to be opened.

Avoid installing the TOSHIBA MMK-UP0301HP-E in the following kinds of locations to ensure proper operation and prevent damage:

• Saline area (coastal area).

• Locations with acidic or alkaline atmospheres (e.g., hot springs, factories with chemicals).

• Locations with atmospheres containing mist of cutting oil or other machine oil.

• Places where iron or other metal dust is present.

• Locations where vapors from food oils are formed (e.g., kitchens).

• Locations near obstructions (e.g., ventilation openings) that can disrupt air flow.

• Locations where an in-house power generator is used for the power supply.

• On moving conveyances like truck cranes or ships.

• For special applications such as storing food, plants, or art works.

• Locations where high frequencies are generated (by inverter equipment, medical equipment, etc.).

• Locations where there is anything under the unit that could be damaged by wetness from condensation.

• For wireless systems, rooms with inverter-type fluorescent lighting or locations exposed to direct sunlight.

• Locations where organic solvents are being used.

• Locations near doors or windows with high-temperature, high-humidity outdoor air.

• Locations where special sprays are used frequently.

Installing Batteries:

1. Remove the battery cover from the wireless remote controller.

2. Insert 2 new batteries (R03 [AAA] type), following the (+) and (-) positions indicated.

Placing the Remote Controller:

• Avoid direct sunlight on the indoor unit’s wireless receiver.

• Ensure the microprocessor in the indoor unit is not too close to RF noise sources.

• Place the remote controller where there are no obstacles, such as a curtain, that may block the signal from the indoor unit.

• Do not install the remote controller in a place exposed to direct sunlight or close to a heating source, such as a stove.

• Keep the remote controller at least 1 meter away from the nearest TV set or stereo equipment to prevent image disturbances or noise interference.

• The remote controller should be located within a 7-meter range of the indoor unit, with a reception angle of 60° (side view) and 45° on each side (top view).

Cutting a hole (for rear piping):

Decide the hole position for piping at 110 mm from the arrow mark (⇨) on the installation plate. Drill a hole (approx. 80 mm diameter) at a slight downward slant toward the outdoor side.

NOTE: When drilling a wall that contains a metal lath, wire lath, or metal plate, be sure to use a pipe hole brim ring (sold separately).

Mounting the installation plate directly on the wall:

1. Securely fit the installation plate onto the wall by screwing it in the upper and lower parts to hook up the indoor unit.

2. To mount the plate on a concrete wall with anchor bolts, use the anchor bolt holes on the plate.

3. Install the installation plate horizontally.

CAUTION:

• When installing the plate with a mounting screw, do not use the anchor bolt hole. Otherwise, the unit may fall.

• Failure to firmly install the unit may result in personal injury and property damage if the unit falls.

• For block, brick, or concrete walls, make 5 mm diameter holes and insert clip anchors for the mounting screws.

• Secure the four corners and lower parts of the installation plate with 6 mounting screws to install it.

First, ensure to insulate both connecting pipes using polyethylene foam to prevent dewing, which can cause machine trouble.

1. Die-cutting front panel slit:

Depending on the piping direction (left, right, bottom-left, bottom-right), cut out the corresponding slit on the front panel with a pair of nippers.

2. Changing drain hose (for leftward connections):

For leftward, bottom-leftward, and rear-leftward piping, you must change the drain hose and drain cap positions.

• To remove the drain hose: Remove the securing screw and pull out the drain hose. Be careful of sharp edges on the steel plate.

• To install the drain hose: Insert the drain hose firmly until the connection part contacts the heat insulator, then secure it with the original screw.

• To remove the drain cap: Clip the drain cap with needle-nose pliers and pull it out.

• To fix the drain cap: Insert a hexagonal wrench (dia. 4 mm) into the center head and firmly insert the cap until there is no gap. Do not apply lubricating oil.

CAUTION: Firmly insert the drain hose and drain cap; otherwise, water may leak.

Piping Connection:

For left-hand connection, bend the connecting pipe so it is laid within 43 mm from the wall surface. Use a spring bender to avoid crushing the pipe. Bend it within a radius of 30 mm.

NOTE: If the pipe is bent incorrectly, the indoor unit may be unstable on the wall. After passing the pipe through the hole, connect it to the auxiliary pipes and wrap the taping around them.

Proper insulation is crucial to prevent condensation and water leaks.

CAUTION: Securely apply insulation all the way up to the pipe connecting section of the indoor unit so that there is no exposed area. A pipe exposed to the outside can cause a water leak. When wrapping the heat insulator around pipes, make sure the slit aperture is toward the ceiling surface.

• Use the heat insulator provided to insulate the indoor unit completely, ensuring there are no gaps.

• Cut the heat insulator of the gas pipe (locally procured) leaving a 10 mm overlap with the shield of the shield pipe.

• Bind the auxiliary pipes (two), power supply wiring, and control wiring with facing tape tightly. For leftward piping, bind only the auxiliary pipes together.

• Carefully arrange pipes so they do not stick out from the rear plate of the indoor unit.

• Insulate both connecting pipes separately. Use polyethylene foam as the insulating material.

• When bending a pipe, do so carefully to avoid crushing it.

Fixing the Indoor Unit:

1. Pass the pipe through the hole in the wall and hook the indoor unit on the installation plate at the upper hooks.

2. Swing the indoor unit right and left to confirm that it is firmly hooked on the installation plate.

3. While pressing the indoor unit onto the wall, hook it at the lower part of the installation plate. Pull the indoor unit toward you to confirm it is firmly hooked.

Requirement: If the lower part of the indoor unit floats due to the piping condition, use the screws provided to fix the unit to the installation plate. This is especially important when pipes are pulled out from the left side.

Drainage Setup:

1. Run the drain hose sloped downwards. The wall hole should also have a slight downward slant to the outdoor side.

2. Pour water into the drain pan to make sure it drains properly outdoors.

3. When connecting an extension drain hose, insulate the connecting part with the shield pipe.

CAUTION: Arrange the drain pipe for proper drainage. Improper drainage can result in dew-dropping.

• Do not let the drain hose rise at any point.

• Do not form the drain hose into a wavy shape.

• Do not put the end of the drain hose into water.

• Do not put the end of the drain hose into a drainage ditch.

CAUTION: Use flare nuts that are included with the unit. Using different flare nuts may cause refrigerant gas leakage.

Refrigerant Piping Material:

Use seamless phosphorous de-oxidized copper pipe.

• 6.35, 9.52, and 12.7 mm wall thickness: 0.8 mm or more.

• 15.88 mm wall thickness: 1.0 mm or more.

Pipe Sizes for MMK-UP027 to UP036 types:

• Gas side: 15.9 mm

• Liquid side: 9.5 mm

Flaring:

1. Cut the pipe with a pipe cutter and remove burrs completely. Remaining burrs may cause gas leakage.

2. Insert a flare nut onto the pipe and flare the pipe. The flaring sizes for R32 or R410A differ from R22.

Projection margin in flaring: B (Unit: mm) – RIDGID (Clutch type)

Outer dia. of copper pipe	Tool used	Conventional tool used
6.4, 9.5	0.5 to 1.0	1.0 to 1.5
12.7, 15.9	0.5 to 1.1	1.5 to 2.0

Flaring diameter size: A (Unit: mm)

Outer dia. of copper pipe	A
6.4	9.1
9.5	13.2
12.7	16.6
15.9	19.7

Incorrect connections can cause gas leaks and refrigeration cycle trouble. Follow these steps:

1. Align the centers of the connecting pipes.

2. Tighten the flare nut as far as possible with your fingers.

3. Use a spanner and a torque wrench to tighten the nut to the specified torque value as shown in the table below.

CAUTION: Do not apply excessive torque, as the nut may crack depending on conditions.

Yes, existing R22 and R410A piping can be reused for inverter R32 product installations like the TOSHIBA MMK-UP0301HP-E, provided certain conditions are met.

WARNING: Confirming the existence of scratches or dents on existing pipes and the reliability of the pipe strength are referred to the local site. If specified conditions can be cleared, it is possible to update existing R22 and R410A pipes to those for R32 models.

Basic Conditions Needed to Reuse Existing Pipes:

1. Dry: There is no moisture inside of the pipes.

2. Clean: There is no dust inside of the pipes.

3. Tight: There are no refrigerant leaks.

Restrictions for Use (When pipes should NOT be reused as is):

• When a scratch or dent is heavy.

• When the existing pipe thickness is thinner than specified (see table below). The operating pressure of R32 is high.

• When the outdoor unit was left with pipes disconnected, or gas leaked and was not repaired (risk of moisture/air ingress).

• When refrigerant cannot be recovered using a recovery unit (risk of dirty oil/moisture).

• When a commercially available dryer is attached to the existing pipes (risk of copper green rust).

• When the refrigerator oil is clearly different from normal (e.g., green color, discolored, large quantity of residue, bad smell, shiny metal dust).

• When the compressor has a history of failing and being replaced.

• If the refrigerator oil of the existing air conditioner is not a compatible type (Mineral oil, Synthetic oil, ester series, PVE).
