SAFETY PRECAUTION

3-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply circuits must be disconnected.

3-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilising refrigerant R410A

Use new refrigerant pipes.

In case of using the existing pipes for R22, be careful with the followings.

· For RP100, 125 and 140, be sure to perform replace ment operation before test run.

· Change flare nut to the one provided with this product. Use a newly flared pipe.

· Avoid using thin pipes.

Make sure that the inside and outside of refrigerant piping is clean and it has no contamination such as sulfur hazardous for use, oxides, dirt, shaving particles, etc. In addition, use pipes with specified thickness.

Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.

Store the piping to be used indoors during installation and both ends of the piping sealed until just before brazing. (Leave elbow joints, etc. in their packaging.)

If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor.

Do not use refrigerant other than R410A.

If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.

Use a vacuum pump with a reverse flow check valve.

Vacuum pump oil may flow back into refrigerant cycle and that can cause deterioration of refrigerant oil etc.

Use the following tools specifically designed for use with R410A refrigerant.

The following tools are necessary to use R410A refrigerant.

Tools for R410A Gauge manifold Charge hose

Gas leak detector

Torque wrench

Flare tool Size adjustment gauge Vacuum pump adaptor

Electronic refrigerant charging scale

Handle tools with care.

If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor.

Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigerant oil applied to flares and flange connections.

If large amount of mineral oil enters, that can cause deterioration of refrigerant oil etc.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.

Ventilate the room if refrigerant leaks during

Charge refrigerant from liquid phase of gas cylinder.

If the refrigerant is charged from gas phase, composition change may occur in refrigerant and the efficiency will be lowered.

operation. If refrigerant comes into contact with a flame, poisonous gases will be released.

[1] Cautions for service

(1) Perform service after recovering the refrigerant left in unit completely. (2) Do not release refrigerant in the air. (3) After completing service, charge the cycle with specified amount of refrigerant. (4) When performing service, install a filter drier simultaneously. Be sure to use a filter drier for new refrigerant.

[2] Additional refrigerant charge

When charging directly from cylinder

· Check that cylinder for R410A on the market is syphon type.

· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

Gravimeter

[3] Service tools

Use the below service tools as exclusive tools for R410A refrigerant.

No. Tool name Specifications 1 Gauge manifold · Only for R410A

· Use the existing fitting

· Use high-tension side pressure of 5.3MPa·G or over. 2 Charge hose · Only for R410A

· Use pressure performance of 5.09MPa·G or over. 3 Electronic scale 4 Gas leak detector · Use the detector for R134a, R407C or R410A. 5 Adaptor for reverse flow check · Attach on vacuum pump. 6 Refrigerant charge base 7 Refrigerant cylinder · Only for R410A · Top of cylinder (Pink)

Note1. Please choose the grille from a standard grille, auto-grille.

2. As for drain pipe, please use VP-25(O.D.

:

32 PVC TUBE). Drain pump is included. Max. lifting height is 850mm from the ceiling.

3. As for suspension bolt, please use M10 or W3/8. (Procured at local site)

4. Electrical box may be removed for the service purpose. Make sure to slack the electrical wire little bit for control/power wires connection.

5. The height of the indoor unit is able to be adjusted with the grille attached.

6. For the installation of the optional high efficiency filter or optional multi-functional casement.

1) Requires E or more space between transom and ceiling for the installation.

2) Add 135 mm to the dimensions + marked on the figure.

3) The optional high efficiency filter becomes optional multi-functional casement and concomitant use.

7. When installing the branch ducts, be sure to insulate adequately. Otherwise condensation and dripping may occur. (It becomes the cause of dew drops/Water dew.)

8. As for necessary installation/service space, please refer to the left figure.

Notes:

1.SymboIs used in wiring diagram above are, :Connector, : Terminal (block).

2.Indoor and outdoor connecting wires have poIarities, make sure to match terminal numbers (S1, S2, S3) for correct wirings.

3.Since the outdoor side electric wiring may change, be sure to check the outdoor unit electric wiring diagram for servicing.

4.This diagram shows the wiring of indoor and outdoor connecting wires.(specification of 230V), adopting superimposed system for power and signal. +1:If indoor and outdoor units have separate power supplies, refer to Fig.1. +2:For power supply system of this unit, refer to the caution label located near this diagram.
