PMGB0400B-rev.2

● Do not touch or adjust any safety devices inside the indoor or outdoor units. All safety features,
disengagement, and interlocks must be in place and functioning correctly before the equipment is put
into operation. If these devices are improperly adjusted or tampered with in any way, a serious accident
can occur. Never bypass or jump-out any safety device or switch.

● Before servicing, turn-OFF the power supply and use accepted lockout and tag out procedures at all
main switches.

● This unit is the pressurized system. Never loosen threaded joints while the system is under pressure
and never open pressurized system parts.

● Johnson Controls will not assume any liability for injuries or damage caused by not following steps

outlined or described in this manual. Unauthorized modications to Johnson Controls products are

prohibited as they…

◦ May create hazards which could result in death, serious injury or equipment damage;
◦ Will void product warranties;
◦ May invalidate product regulatory certications;
◦ May violate OSHA standards;

Take the following precautions to reduce the risk of property damage.

● Be careful that moisture, dust, or variant refrigerant compounds not enter the refrigerant cycle during
installation work. Foreign matter could damage internal components or cause blockages.

● If air lters are required on this unit, do not operate the unit without the air lter set in place. If the air

lter is not installed, dust may accumulate and breakdown may result.

● Do not install this unit in any place where silicon gases can coalesce. If the silicon gas molecules
attach themselves to the surface of the heat exchanger, the nned surfaces will repel water. As a
result, any amount of drainage moisture condensate can overow from the drain pan and could run

inside of the electrical box, possibly causing electrical failures.

● When installing the unit in a hospital or other facility where electromagnetic waves are generated
from nearby medical and/or electronic devices, be prepared for noise and electronic interference
Electromagnetic Interference (EMI). Do not install where the waves can directly radiate into the
electrical box, controller cable, or controller. Inverters, appliances, high-frequency medical equipment,
and radio communications equipment may cause the unit to malfunction. The operation of the unit
may also adversely affect these same devices. Install the unit at least 10 ft. (3m) away from such
devices.

● When a wireless controller is used, locate at a distance of at least 3.3 ft. (1m) between the indoor

unit and electric lighting. If not, the receiver part of the unit may have difculty receiving operation

commands.

● Do not install the unit in any location where animals and plants can come into direct contact with the
outlet air stream. Exposure could adversely affect the animals and plants.

● Do not install the unit with any downward slope to the side of the drain adaptor. If you do, you may

have drain water owing back which may cause leaks.

● Be sure the drain hose discharges water properly. If connected incorrectly, it may cause leaks.

● Do not install the unit in any place where oil can seep onto the units, such as table or seating areas in
restaurants, and so forth. For these locations or social venues, use specialized units with oil-resistant
features built into them. In addition, use a specialized ceiling fan designed for restaurant use. These
specialized oil-resistant units can be ordered for such applications. However, in places where large
quantities of oil can splash onto the unit, such as a factory, even the specialized units cannot be used.
These products should not be installed in such locations.

Installation Precautions

To reduce the risk of serious injury or death, the following installation

precautions must be followed.

● When installing the unit into…

▫ A wall: Make sure the wall is strong enough to hold the unit’s weight. It may be necessary to

construct a strong wood or metal frame to provide added support.

▫ A room: Properly insulate any refrigerant tubing run inside a room to prevent “sweating” that can

cause dripping and water damage to wall and oors.

PMGB0400B-rev.2

3

▫ Damp or uneven areas: Use a raised concrete pad or concrete blocks to provide a solid, level

foundation for the unit to prevent water damage and abnormal vibration.

▫ An area with high winds: Securely anchor the outdoor unit down with bolts and a metal frame.

Provide a suitable air bafe.

▫ A snowy area: Install the outdoor unit on a raised platform that is higher than drifting snow. Provide

snow vents.

● Do not install the unit in the following places. Doing so can result in an explosion, re, deformation,
corrosion, or product failure.

▫ Explosive or ammable atmosphere
▫ Where a re, oil, steam or powder can directly enter the unit, such as nearby or above a kitchen

stove.
▫ Where oil (including machinery oil) may be present.
▫ Where corrosive gases such as chlorine, bromine, or sulde can accumulate, such as near a hot

tub or a hot spring.
▫ Where dense, salt-laden airow is heavy, such as in coastal regions.
▫ Where the air quality is of high acidity.
▫ Where harmful gases can be generated from decomposition.

● Do not position the drain pipe for the indoor unit near any sanitary sewers where corrosive gases
may be present. If you do, toxic gases can seep into breathable air spaces and can cause respiratory

injuries. If the drain pipe is installed incorrectly, water leakage and damage to the ceiling, oor,

furniture, or other possessions may result. If the drain pipe becomes clogged, water may drip from the
indoor unit. Do not install the indoor unit where such dripping can cause moisture damage or uneven
locations: Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the unit
to prevent water damage and abnormal vibration.

● Before performing any brazing work, be sure that there are no ammable materials or open ames
nearby.

● Perform a test run to ensure normal operation. Safety guards, shields, barriers, covers, and protective

devices must be in place while the compressor/unit is operating. During the test run, keep ngers and

clothing away from any moving parts.

● Clean up the site when nished, remembering to check that no metal scraps or bits of wiring have
been left inside the unit being installed.

After installation work for the system has been completed, explain the “Safety Precautions,” the proper use
and maintenance of this unit to the customer according to the information in all manuals that came with the
system. All manuals and warranty information must be given to the user or left near the Indoor Unit.

PMGB0400B-rev.2

Refrigerant Precautions

To reduce the risk of serious injury or death, the following refrigerant

precautions must be followed.

● As originally manufactured, this unit contains refrigerant installed by Johnson Controls. Johnson

Controls uses only refrigerants that have been approved for use in the unit’s intended home country

or market. Johnson Controls distributors similarly are only authorized to provide refrigerants that
have been approved for use in the countries or markets they serve. The refrigerant used in this unit

is identied on the unit’s faceplate and/or in the associated manuals. Any additions of refrigerant into
this unit must comply with the country’s requirements with regard to refrigerant use and should be

obtained from Johnson Controls distributors. Use of any non-approved refrigerant substitutes will void
the warranty and will increase the potential risk of injury or death.

● If installed in a small room, take measures to prevent the refrigerant from exceeding the maximum
allowable concentration in the event that refrigerant gases should escape. Refrigerant gases can
cause asphyxiation (0.026 lbs/ft

3

(0.42 kg/m3) based on ISO 5149 for R410A). Consult with your
distributor for countermeasures (ventilation system and so on). If refrigerant gas has leaked during the
installation work, ventilate the room immediately.

● Before installation is complete, make sure that the refrigerant leak test has been performed. If

refrigerant gases escape into the air, turn OFF the main switch, extinguish any open ames and

contact your service contractor. Refrigerant (Fluorocarbon) for this unit is odorless. If the refrigerant

should leak and come into contact with open ames, toxic gas could be generated. Also, because the
uorocarbons are heavier than air, they settle to the oor, which could cause asphyxiation.

● When installing the unit, and connecting refrigerant piping, keep all piping runs as short as possible,
and make sure to securely connect the refrigerant piping before the compressor starts operating. If
the refrigerant piping is not connected and the compressor activates with the stop valve opened, the

refrigerant cycle will become subjected to extremely high pressure, which can cause an explosion or re.

● Tighten the are nut with a torque wrench in the specied manner. Do not apply excessive force to the
are nut when tightening. If you do, the are nut can crack and refrigerant leakage may occur.

● A compressor/unit comprises a pressurized system. Never loosen threaded joints while the system is
under pressure and never open pressurized system parts.

● When maintaining, relocating, and disposing of the unit, dismantle the refrigerant piping after the
compressor stops.

Electrical Precautions

Take the following precautions to reduce the risk of electric shock, re or

explosion resulting in serious injury or death.

● Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and
these instructions when wiring. Improper connections and inadequate grounding can cause serious
injury or death.

● Before servicing, open and tag all disconnect switches. Never assume electrical power is
disconnected. Check with meter and equipment.

● Only use electrical protection equipment and tools suited for this installation.

● Use specied cables between units.

● Communication cable should be a minimum of AWG18 (0.82mm

2

), 2-Conductor, Stranded Copper.
Shielded cable must be considered for applications and routing in areas of high EMI and other
sources of potentially excessive electrical noise to reduce the potential for communication errors.
When shielded cable is applied, proper bonding and termination of the cable shield is required as per
Johnson Controls guidelines. Plenum and riser ratings for communication cables must be considered
per application and local code requirements.

● Use an exclusive power supply for the air conditioner at the unit’s rated voltage.

● Be sure to install circuit breakers (ground fault interrupter, isolating switch, molded case circuit

breaker and so on), with the specied capacity. Ensure that the wiring terminals are tightened
securely to recommended torque specications. If a circuit breaker or fuse is frequently activated,

shut down the system and contact your service contractor.

PMGB0400B-rev.2

5

● Clamp electrical wires securely with a cable clamp after all wiring is connected to the terminal block.
In addition, run wires securely through the wiring access channel.

● When installing the power lines, do not apply tension to the cables. Secure the suspended cables at
regular intervals, but not too tightly.

● Make sure that the terminals do not come into contact with the surface of the electrical box. If the
terminals are too close to the surface, it may lead to failures at the terminal connection.

● Turn OFF and disconnect the unit from the power supply when handling the service connector. Do not
open the service cover or access panel to the indoor or outdoor units without turning OFF the main
power supply.

● After stopping operation, be sure to wait at least ve minutes before turning off the main power
switch. Otherwise, water leakage or electrical breakdown may result. Disconnect the power supply
completely before attempting any maintenance for electrical parts. Check to ensure that no residual
voltage is present after disconnecting the power supply.

● Do not clean with, or pour water into, the controller as it could cause electric shock and/or damage the
unit. Do not use strong detergent such as a solvent. Clean with a soft cloth.

● Check that the ground wiring is securely connected. Do not connect ground wiring to gas piping,
water piping, lighting conductor, or telephone ground wiring.

● If a circuit breaker or fuse is frequently activated, shut down the system and contact your service
contractor.

● This equipment can be installed with a Ground Fault Circuit Breaker (GFCI), which is a recognized measure for
added protection to a properly grounded unit. Install appropriate sized breakers / fuses / overcurrent protection
switches, and wiring in accordance with local, state and NEC codes and requirements. The equipment installer
is responsible for understanding and abiding by applicable codes and requirements.

6

PMGB0400B-rev.2

● Proper handling of this unit requires two people. Safe handling and installing of the indoor unit requires

the strength of two people. Mounting the unit alone may cause injury due to a fall of the unit. Although

the unit may be girded with steel banding, do not use it for transportation. Avoid contact with nned
surfaces of the heat exchanger as sharp edges can cause severe injury to hands and ngers. Use

appropriate work gloves for the job.

NOTICE

● Check to ensure that the drain hose discharges moisture properly. If connected incorrectly, it can result in

leakage and damage to furniture.

● Do not apply an excessive force to the drain pipe connection. This can also compromise the seal

properties of the connection.

● Verify that the installed unit is level with oor and ceiling surfaces. Any variance or inclination can cause

moisture to back up into the drain pan, overow, and seepage onto ceiling or wall surfaces, and cause

damage to carpeted surfaces or furniture below.

● Do not install this system in close proximity to septic sewer lines where ammable and toxic gases can coalesce.

● Inspect the drain pan before the onset of winter to drain away all accumulated moisture in the pan.

● The heat exchanger of indoor unit overheats whenever there is a slight amount of refrigerant circulating

during slowdown or stoppage. As a result, moisture in the drain pan evaporates where it can condense on
ceiling or wall surfaces.

● After the drain check is completed, insert the rubber plug again and seal the gap with a silicone sealant.

Electrical Installation

In some cases, the packaged air conditioner may not be operated normally under the following cases:

● When electrical power for the packaged air conditioner is supplied from the same power transformer
as the device*.

● When the power supply wiring for the device* and the packaged air conditioner are located close to
each other:

Device*(Example): Lift, container crane, rectier for electric railway, inverter power device, arc

furnace, electric furnace, large-sized induction motor, and large-sized switch.
It consumes large quantities of electrical power.

Regarding that mentioned above, surge voltage may be inducted into the power supply wiring for the crated
air conditioner due to a spike in power consumption for this device and an activation of the switch. Check

the eld regulations and standards before performing any electrical work in order to safeguard the power

supply for the crated air conditioning unit.

(5mm)

Figure 5.6 Foundation Gradient

(2) The unit should be installed so that the right side of the unit is slightly (0 to 3/16 inch (0 to 5mm)) lower

than the left side to allow and promote drainage discharge.

(3) Tighten the bolts of the suspension nuts with the suspension brackets after adjustment is completed.

Special threadlocking compound must be applied to the bolts in order to prevent them from loosening.

NOTE:

During the installation process, keep the unit well covered with vinyl cover and related components
covered until it is time to hoist into position.

5.5 Ducting Arrangement

This unit has been designed for positive introduction of the outdoor air for free cooling or other control. Check
to ensure that the following points have been previously designed or arranged.

5.5.1 Pressure Drop of Outdoor Air Duct

In order to protect against a shortage of outdoor air intake or excessive intake of outdoor air, which causes

insufcient capacity of free cooling or uncomfortable change of supply air during free cooling operation,

keep the pressure drop of the outdoor air duct within the following guide range:

1/2 P

R

< PO < 4 x P

R

PR: Pressure Loss of Return Air Duct at Designed Supply Air Volume
PO: Pressure Loss of Outdoor Air Duct at Designed Supply Air Volume, Including the Outdoor Air Filter

5.5.2 Pressure Relief Damper

When the building is of an air-tight structure, positive pressure inside the building will be created during the
free cooling or all-fresh operation.

The balance between the outdoor air volume and the return air volume depends on the arrangement of the
discharge air duct, return air duct, and installed duct arrangement.

NOTICE

PMGB0400B-rev.2

5.6 Example of Installation

5.6.1 Ducting Connection

Pre-drilled duct anges are provided at the supply, return and outdoor air intake connections. It is
recommended that a exible duct connection be installed to minimize sound and vibration transmission.

5.6.2 Insulation

All ducts should be insulated.

● Especially the outdoor air duct, through which the cold outdoor air ows in, must be sufciently insulated.

● The lowest temperature of the entering outdoor air owing through the outdoor air duct is the lowest

temperature for heating operation at the installation site.

● If the unit is used under high relative humidity around the unit or cold outdoor airows in, perform

additional insulation (*) to the unit and ducts or prepare a drain pan underneath the unit.

5.7 Connecting Supply Duct

(1) An air lter is not included with accessories of the unit. Install the air lters in the duct of air inlet side

which has higher than 50% of dust-collecting efciency.

(2) If reducing the noise by the indoor unit is necessary, install silencers (eld-supplied).

(3) The canvas ducts should be connected between the indoor unit and the supply duct as shown next

page in order to avoid abnormal sound vibration.

(4) Attach vibration-proof rubber gasket (eld-supplied) to suspension bolts in order to avoid abnormal

sound vibration.

(5) Design the duct arrangement as “Unit External Static Pressure = Duct Pressure Loss + Suction/

Discharge Pressure Loss”. If the duct design is not correct, a louder noise, splashing water, etc., will
occur. The damper or the duct fan, etc., should be used to adjust the fresh air volume to let the unit's
external static pressure be approximately within pressure loss of duct.

(6) If pressure loss of duct is excessive, change the installation location of the unit or the shape of ducts in

order to let the design arrangement be within the unit's external static pressure.

(7) Make sure that a service access panel is mounted on the ceiling for the service of electrical parts,

motor, etc. If the service access panel can not be mounted on the ceiling, an alternative opening should
be prepared on the ceiling. It should be a suitable size for the indoor unit to be installed and removed
easily and for a fan, a heat exchanger and a drain pan to be installed through it.

(8) Install thermal insulations over the duct to prevent it from dew condensation.

(9) Do not install the duct in the following places.

- Places where there is direct radiant heat from sunlight or heat sources.

- Places where corrosive gases, volatile gases and explosive gases are generated.

- Places where air intake such as a kitchen or similar where vapor from oil or its mist ows to the indoor

unit.

In addition, install a protection hood and cover the air inlet with a net or similar to stop any insects or

small animals from entering.

(10) Conduct periodic maintenance of the air lter and a periodic check for clogging of condensate piping

carefully when the indoor unit is installed where there is a lot of activity. Be extra mindful when installing
in places where strong salty wind can be present (coast region, etc.). Consult with your distributor for
countermeasures for periodic maintenance and contract to replace the heat exchanger.

(11) Install the ducts with the air inlet being at a lower level than the indoor unit to protect the unit from rain.

(12) If the indoor is negative pressure while this indoor unit stopped, outdoor air may enter the room through

the indoor unit. Outdoor intake shutter should be provided.
Otherwise, following problems may occur.

● Condensation buildup on the ducts and indoor units when outdoor temperature is low.

● Affects air conditioning load and uncomfortableness when outdoor temperature is high.

(3) Prepare the eld-supplied copper piping.

(4) Select clean copper pipes. Make sure there is no dust and moisture inside.

(5) The refrigerant oil used in combination with refrigerant R410A is susceptible to moisture, oxide lm, oil,

and fat. Exercise special care during the installation so that moisture, particulate contamination, or old
refrigerant oil will not enter the refrigerant cycle. Otherwise, impurities may adhere to the expansion
valve and it may prevent the proper operation.

(6) Caution: When cutting piping, do not use tools such as saws and a grinding wheel. They can produce

harmful metallic lings that can damage a refrigerant system. Use a pipe cutter to eliminate any metal
lings. After the cut is made, blow out each pipe with dry compressed air or nitrogen to remove this

residue before making pipe connections.

6.1 Piping Materials

(1) Tolerances for refrigerant piping lengths depend on the combination with the outdoor unit. Refer to the

“Installation and Maintenance Manual” for the outdoor unit for details.

(2) Select the piping size from the following table.

For details on refrigerant piping work, vacuum pump, and refrigerant charge, refer to the "Installation and
Maintenance Manual" for the outdoor unit.

Use the specied non-ammable refrigerant (HFC R410A) for the outdoor unit. Do not charge the unit
with anything other than HFC R410A, such as hydrocarbon refrigerants (propane and Isobutene),
oxygen, and other ammable gases (acetylene, ammonia, and so forth), or any poisonous gases
when installing, maintaining and moving the unit. These substances are volatile and dangerous and
can result in re, explosion, and serious or fatal injuries.

(6) Wherever buried piping exists on site, make sure there is adequate access to inspect piping sockets

and elbows, and for interconnecting parts.

(7) Piping must be reinforced to not be damaged by an external force.

(8) Make sure that the piping can accommodate expansion and contraction.

(9) Prevent the pipes from touching walls, ceiling, etc.

(10)Test for air-tight integrity. This should be done in accordance with the "Installation and Maintenance

Manual" for the outdoor unit.

(11) If temperature and humidity inside the room exceed 80.6°F (27°C)/RH80%, condensation occurs on

the surface of the insulation (eld-supplied). Wrap additional insulation (approximately 3/16~3/8 inch
(5~10mm) thickness) around the insulation (eld-supplied) of the refrigerant pipe as a preventive

measure.

(12) Insulate each are connection without gap with insulations (eld-supplied) to prevent condensation. Also

insulate each refrigerant pipe as well.

● Do not apply excessive force to the are nut when tightening. The are nut may crack due to stress
fracture and refrigerant leakage may occur. Use the correct torque specications.

● Make sure that a refrigerant leak test has been performed. Refrigerant (uorocarbon) for this unit
is non-ammable, non-toxic, and odorless. If the refrigerant should escape and come into contact
with ame, toxic gas will form. This gas is heavier than air and will settle near oor areas and

spread where it can cause asphyxiation to people.

9.1 Before Test Run

Verify there are no problems with the installation. Do not perform Test Run until all the following conditions
have been resolved.

Refer to the "Installation and Maintenance Manual" for the outdoor unit for details on Test Run operations

from the outdoor unit.
Verify that refrigerant piping and the communication cable are connected to the same refrigerant system. If
not, it will cause an abnormal operation and damage to instrumentation.

(1) Verify that electrical resistance is more than one megaohm, by measuring the resistance between

ground and the terminal the terminus for electrical components. If the electrical resistance is less than
one megaohm, do NOT operate the system until the ground fault is detected and repaired. Do not
introduce any high voltage to the terminals of the communication cables
(TB2 [A, B, 1 and 2]).

(2) Verify that each wire is connected correctly at the correct phase for the power supply. If it is incorrectly

connected, the unit will not operate and the wired controller will display the alarm code “05”. In this case,

check the phase for the primary power supply according to the “Attention” label afxed to the back side

of the service cover. Then, with the power supply turned OFF at the power supply, re-do the necessary
connections.

(3) Apply power to the outdoor unit(s) at least 12 hours prior to operation of the system for preheating of the

compressor oil.

(4) Verify that all DIP switch settings are correct. Refer to Section 8.6 “DIP Switch Settings”.

9.2 Test Run

After all installation work is completed, a test run should be performed.

(1) Check to ensure that stop valves (gas and liquid) for the outdoor unit are fully opened.

(2) Whenever indoor units are connected to the VRF system, perform the test run for the indoor units one

by one sequentially and then check the refrigerant piping system and the electrical wiring system for

conformity. (If multiple indoor units are operated simultaneously, system conformity cannot be veried.)

(3) Perform the test run in accordance with the following procedures. Ensure that the test run is carried out

without any problem. The following procedures show a case where a wired controller is utilized. If other

controllers are activated instead, refer to the "Installation and Maintenance Manual" for those other

controllers.
