RAV -SP1100, 1400AT-E RAV -SM1100, 1400AT-E

• Ensure that all Local, National and International regulations are satisfied.

• Read this “PRECAUTIONS FOR SAFETY” carefully before Installation.

• The precautions described below include the important items regarding safety. Observe them without fail.

• After the installation work, perform a trial operation 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.

PRECAUTIONS FOR SAFETY

CAUTION New Refrigerant Air Conditioner Installation

• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DE-

STROY OZONE LAYER.

The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the ne w refrigerant, refrigerating oil has also been changed. Therefore , during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle.

To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the main unit and installation tools are charged from those for the conventional refrigerant.

Accordingly the exclusive tools are required for the new refrigerant (R410A). For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust

does not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance force and impurity in it.

CAUTION To Disconnect the Appliance from Main Power Supply.

This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm.

The installation fuse (25A D type ) must be used for the power supply line of this conditioner.

WARNING

• Ask an authorized dealer or qualified installation professional to install/maintain the air condi-

tioner.

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

• 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.

• Connect the connecting cable correctly.

If the connecting cable is connected in a wrong way, electric parts may be damaged.

• 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 may resultingly causes pipe burst and injuries on persons.

• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety

interlock switches.

• Exposure of unit to water or other moisture before installation may cause a short-circuit of

electrical parts.

Do not store it in a wet basement or expose to rain or water.

• After unpacking the unit, examine it carefully if there are possible damage .

• Do not install in a place that might increase the vibration of the unit.

• To avoid personal injury (with sharp edges), be careful when handling parts.

• 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 cables for wiring connect the terminals securely fix. To prevent external

forces applied to the terminals from affecting the terminals.

• Be sure to provide grounding.

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

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

Inappropriate grounding may cause electric shock.

• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.

EVACUATING

Air Purge

This air conditioner can be installed up to the connecting pipe length and height difference in the following table.

Capacity rank

SM1100, SM1400 type

SP1100, SP1400 type

With respect to the preservation of terrestrial environment, adopt “Vacuum pump” for air purge (Evacuate air in the connecting pipes) when installing the unit.

• Do not discharge the refrigerant gas to the atmosphere to preserve the terrestrial environment.

• Use a vacuum pump to discharge the air (nitrogen, etc.) remained in the set. If the air remains, the capacity

may decrease.

For the vacuum pump, be sure to use one with backflow preventer so that the oil in the pump does not backflow into the pipe of the air conditioner when the pump stops. (If oil in the vacuum pump is put in an air conditioner including R410A, it may cause trouble on the refrigeration cycle .)

FINAL INSTALLATION CHECKS

Check and Test Operation

For R410A, use the leak detector e xclusiv ely manufactured for HFC refrigerant (R410A, R134a, etc.). The conventional leak detector for HCFC refrigerant (R22, etc.) cannot be used because its sensitivity for HFC

refrigerant lowers to approx. 1/40.

• Pressure of R410A is approx. 1.6 times higher than that of R22.

If installation work is incompletely finished, a gas leakage may occur when pressure rises during operation. Therefore, be sure to test the piping connections for leakage.

• Check gas leakage at the flare nut connections, valve stem cap connections and service port cap fittings with a

leak detector or soap water.

CAUTION

When the remote controller is used for the first time, it accepts an operation approx. 5 minutes after the power supply has been turned on.

It is not a trouble, b ut is because the setup of the remote controller is being checked. For the second pow er-ON time and after, approx. 1 mun ute is required to start the operation by the remote controller .

Useful Functions

In addition to the code checking by remote controller of the indoor unit, troub les of the outdoor unit can be diagnosed by LED indications on the cycle control P.C. board of the outdoor unit. Utilize them for various checks. For the check by remote controller of the indoor unit, refer to the Installation Manual of the indoor unit. Before a check, confirm each bit of the DIP switch SW800 is set to OFF position.

Installation/Servicing T ools

In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, service port diameter of the outdoor unit control valv e (3 way valve) has been changed. (1/2 UNF 20 threads per inch)

• In order to increase the pressure resisting strength of the refrigerant piping flare processing diameter and size of

opposite side of flare nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)

Changes

As pressure is high, it is impossible to measure by means of conventional gauge. In order to prevent any other refrigerant from being charged, each port diameter is changed.

In order to increase pressure resisting strength, hose materials and port size are changed (to 1/2 UNF 20 threads per inch). When purchasing a charge hose, be sure to check the port size.

As pressure is high and gasification speed is fast, it is difficult to read the indicated value by means of charging cylinder, as air bubbles occur.

The size of opposite sides of flare nuts have been increased. Incidentally, a common wrench is used for nominal diameters 1/4 and 3/8.

By increasing the clamp bar’s receiving hole, strength of spring in the tool has been improved.

Gauge for projection adjustment

Vacuum pump adapter

Gas leakage detector

• Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the

U,S. ’s ARI specified rose color (ARI color code: PMS 507).

• Also, the “charge port and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch corresponding to

the charge hose’s port size.

Used when flare is made with using conventional flare tool. Connected to the conventional vacuum pump. It is necessary to use an

adapter to prevent vacuum pump oil from flowing back to the charge hose. The charge hose connecting part has two por ts-one for conventional refrigerant (7/16 UNF 20 threads per inch) and one for R410A. If the vacuum pump oil (mineral) mixes with R410A a sludge may occur and damage the equipment.

PRECAUTIONS FOR SAFETY

CAUTION New Refrigerant Air Conditioner Installation

• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE LAYER.

The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle.

Accordingly the exclusive tools are required for the new refrigerant (R410A). For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does

not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance force and impurity in it.

CAUTION To Disconnect the Appliance from Main Power Supply.

This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm.

The installation fuse (25A D type ) must be used for the power supply line of this conditioner.

WARNINGS

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

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

• 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.

• Connect the connecting cable correctly.

If the connecting cable is connected in a wrong way, electric parts may be damaged.

• 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 may resultingly causes pipe burst and injuries on persons.

• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety interlock switches.

• Exposure of unit to water or other moisture before installation may cause a short-circuit of electrical parts.

Do not store it in a wet basement or expose to rain or water.

The air supply ducting work is classified in two ways, one is branched by the round ducts, and the other is branched by the square ducts. (Be sure to divide the air supply duct into three or more branches.)

In case of the round duct, use the thermal insulator of thickness 25mm or more and inner diameter 150mm or more to the duct board. (If the inner diameter is not enough, resistance increase, as the result, air does not flow smoothly and loss of the static pressure increases.) For the thermal insulator, use high-density glass wool of 24kg/m3 or equivalent.

Density of thermal insulator (glass wool) is

25mm or more

24 kg/m³ or equivalent.

Ø150mm or more

<Square duct> (Reference for square duct)

When using the square duct, change the type of the air supply flange from round type to square flange at the local site.

In case of the square duct, apply the thermal insulator of thickness 25mm or more to the duct board. For the thermal insulator, use high-density glass wool of weight 64kg/m3.

n General cautions

1. Considering installation places of indoor unit supply chamber, structure of the building and determine the duct path.

2. In order to utilize the static pressure characteristics of the air supply in the indoor unit, design the duct branching having the large size of the air supply chamber or setting distance to the first branch as long as possible (Min. : 200mm or longer) so that an even air volume can be obtained.

Especially, when branching just after air supply of the indoor unit, air concentrates at the center part and is difficult to flow to the ducts at both sides.

3. Connect each connecting section surely, and apply sufficient thermal insulation. In this model of which the duct is branched in the ceiling, compared with the model for ordinary houses, the high

temperature generates on the periphery in the cooling time (Especially, at attic and etc.), temperature difference increases between the supply air and outside of the duct, and dewing may occur.

Dewing on the surface of the thermal insulator covering the metal connecting section or leaking portion of the cooled air may cause a trouble such as water drops.

4. Thermal insulation of screwing sections is necessary. Prevent dewing by applying thermal insulation to 6 screws those fix the duct flange of the air supply chamber.

• For duct parts, the flexible branch duct (thermal insulation, 25mm or more thickness) is recommended.

• Adjust the duct length to 6m or less even for straight pipe, and avoid sharp bending (Air flow resistance is

large.) if bending.
