SAFETY PRECAUTION

Cautions for units utilising refrigerant R410A

2-2. CAUTIONS RELATED TO NEW REFRIGERANT

2-1. ALWAYS OBSERVE FOR SAFETY

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

[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

(1) Check that cylinder for R410A available on the market is a syphon type.
(2) Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

Use new refrigerant pipes.

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

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

· Be sure to clean the pipes and make sure that the insides
of the pipes are clean.

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

· Avoid using thin pipes.

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.

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.

Handle tools with care.

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

Do not use a charging cylinder.

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

Flare tool

Electronic refrigerant
charging scale

Vacuum pump adaptor

Size adjustment gauge

Gauge manifold

Torque wrench

Gas leak detector

Charge hose

Tools for R410A

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

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

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

Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.

Make sure that the inside and outside of refrige­rant piping is clean and it has no contaminants
such as sulfur, oxides, dirt, shaving particles, etc,
which are hazard to refrigerant cycle.
In addition, use pipes with specified thickness.

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the
unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the
spec labels provided with our products.
We will not be held responsible for mechanical failure,
system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.

Use the specified refrigerant only.

The refrigerant oil applied to flare and flange
connections must be ester oil, ether oil or
alkylbenzene oil in a small amount.

NOTE1. CHOOSE THE GRILLE AMONG THE DEDICATED GRILLES.

2. REINFORCE THE SUSPENSION BOLT FOR EARTHQUAKE-RESISTANCE AS NEEDED.

3. FOR THE SUSPENSION BOLT, USE M10 OR W3/8.

(PROCURED AT THE LOCAL SITE.)

4. FOR DRAIN PIPE, USE VP-25（O.D.

Φ 32 PVC TUBE）.

DRAIN PUMP INCLUSION.

RAISE IS MAX 850㎜ FROM THE CEILING.

5. ELECTRICAL BOX MAY BE REMOVED FOR THE SERVICE PURPOSE.

MAKE SURE TO SLACK THE ELECTRICAL WIRE LITTLE BIT FOR

CONTROL/POWER WIRES CONNECTION.

6. THE HEIGHT OF THE INDOOR UNIT IS ABLE TO BE ADJUSTED

WITH THE GRILLE ATTACHED.

7. REQUIRES "E" OR MORE SPACE BETWEEN TRANSOM AND CEILING FOR THE INSTALLATION.

8. WHEN INSTALLING THE BRANCH DUCTS, BE SURE TO INSULATE ADEQUATELY.

OTHERWISE CONDENSATION AND DRIPPING MAY OCCUR.

(IT BECOMES THE CAUSE OF DEW DROPS/WEAR DEW.)

9. AS FOR NECESSARY INSTALLATION/SERVICE SPACE, PLEASE REFER TO THE

RIGHT AT FIGURE.

10. FOR THE INSTALLATION OF THE OPTIONAL HIGH EFFICIENCY FILTER OR

MULTI-FUNCTIONAL CASEMENT, REFER TO SPECIAL DRAWING.
