Fujitsu 9RLS3H Installation Manual

Installation must be performed in accordance with the requirement of NEC and CEC by

authorized personnel only.

1.1. IMPORTANT! Please read before starting

This air conditioning system meets strict safety and operating standards.

As the installer or service person, it is an important part of your job to install or service the

system so it operates safely and effi ciently.

For safe installation and trouble-free operation, you must:

• Carefully read this instruction booklet before beginning.

• Follow each installation or repair step exactly as shown.

• Observe all local, state, and national electrical codes.

• Pay close attention to all warning and caution notices given in this manual.

If Necessary, Get Help

These instructions are all you need for most installation sites and maintenance conditions.

If you require help for a special problem, contact our sales/service outlet or your certifi ed

dealer for additional instructions.

In Case of Improper Installation

The manufacturer shall in no way be responsible for improper installation or maintenance

service, including failure to follow the instructions in this document.

1.2. Special precautions

When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A

QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.

• Do not supply power to the unit until all wiring and tubing are completed or reconnected

and checked.

• Highly dangerous electrical voltages are used in this system. Carefully refer to the wir-

ing diagram and these instructions when wiring. Improper connections and inadequate

earthing (grounding) can cause accidental injury or death.

• Earth (Ground) the unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause overheating at connection points

and a possible fi re hazard.

When Transporting

Be careful when picking up and moving the indoor and outdoor units. Get a partner to

help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin

aluminum fi ns on the air conditioner can cut your fi ngers.

When Installing...

...In a Ceiling or Wall

Make sure the ceiling/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

...In a Room

Properly insulate any tubing run inside a room to prevent "sweating" that can cause drip-

ping and water damage to walls and fl oors.

...In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the

outdoor unit. This prevents water damage and abnormal vibration.

...In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame.

Provide a suitable air baffl e.

...In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting snow.

When Connecting Refrigerant Tubing

• Keep all tubing runs as short as possible.

• Use the fl are method for connecting tubing.

• Apply refrigerant lubricant to the matching surfaces of the fl are and union tubes before

connecting them, then tighten the nut with a torque wrench for a leak-free connection.

• Check carefully for leaks before opening the refrigerant valves.

NOTE:

Depending on the system type, liquid and gas lines may be either narrow or wide. There-

fore, to avoid confusion the refrigerant tubing for your particular model is specifi ed as

either "small" or "large" rather than as "liquid" or "gas".

When Servicing

• Turn the power OFF at the main circuit breaker panel before opening the unit to check

or repair electrical parts and wiring.

• Keep your fi ngers and clothing away from any moving parts.

• Clean up the site after you fi nish, remembering to check that no metal scraps or bits of

wiring have been left inside the unit being serviced.

• After installation, explain correct operation to the customer, using the operating manual.

WARNING

To avoid getting an electric shock, never touch the electrical components soon after the

power supply has been turned off. After turning off the power, always wait 10 minutes or

more before you touch the electrical components.

Installation of this product must be done by experienced service technicians or

professional installers only in accordance with this manual. Installation by non-

professional or improper installation of the product might cause serious accidents such

as injury, water leakage, electric shock, or fi re. If the product is installed in disregard of

the instructions in this manual, it will void the manufacturer's warranty.

Do not turn on the power until all work has been completed. Turning on the power before

the work is completed can cause serious accidents such as an electric shock or a fi re.

If refrigerant leaks when you are working, ventilate the area. If the leaking refrigerant is

exposed to a direct fl ame, it may produce a toxic gas.

Installation must be performed in accordance with regulations, codes, or standards for

electrical wiring and equipment in each country, region, or the installation place.

Do not use this equipment with air or any other unspecifi ed refrigerant in the refrigerant

lines. Excess pressure can cause a rupture.

During installation, make sure that the refrigerant pipe is attached fi rmly before you

run the compressor. Do not operate the compressor under the condition of refrigerant

piping not attached properly with 2-way or 3-way valve open. This may cause abnormal

pressure in the refrigeration cycle that leads to rupture and even injury.

When installing or relocating the air conditioner, do not mix gases other than the

specifi ed refrigerant (R410A) to enter the refrigerant cycle.

If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to

an abnormally high value and cause rupture, injury, etc.

For appropriate working of the air conditioner, install it as written in this manual.

To connect indoor unit and outdoor unit, or indoor unit and branch box, use air

conditioner piping and cables available through your local distributor. This manual

describes proper connections using such installation set.

Do not modify power cable, use extension cable or branch wiring. Improper use may

cause electric shock or fi re by poor connection, insuffi cient insulation or over current.

Do not purge the air with refrigerants but use a vacuum pump to vacuum the installation.

There is no extra refrigerant in the outdoor unit for air purging.

Do not use means to accelerate the defrosting process or to clean, other than those

recommended by the manufacturer.

The appliance shall be stored in a room without continuously operating ignition sources

(for example: open fl ames, an operating gas appliance or an operating electric heater.

Do not pierce or burn.

Be aware that refrigerants may not contain an outdoor.

Using the same vacuum pump for different refrigerants may damage the vacuum pump

or the unit.

Use a clean gauge manifold, vacuum pump and charging hose for R410A exclusively.
