2. The standards for minimum room volume are as  
follows.  
Check of Density Limit  
The room in which the air conditioner is to be  
installed requires a design that in the event of  
refrigerant gas leaking out, its density will not  
exceed a set limit.  
(1) No partition (shaded portion)  
The refrigerant (R410A), which is used in the air condi-  
tioner, is safe, without the toxicity or combustibility of  
ammonia, and is not restricted by laws imposed to pro-  
tect the ozone layer. However, since it contains more  
than air, it poses the risk of suffocation if its density  
should rise excessively. Suffocation from leakage of  
refrigerant is almost non-existent. With the recent  
increase in the number of high density buildings, how-  
ever, the installation of multi air conditioner systems is  
on the increase because of the need for effective use  
of floor space, individual control, energy conservation  
by curtailing heat and carrying power, etc.  
(2) When there is an effective opening with the adja-  
cent room for ventilation of leaking refrigerant gas  
(opening without a door, or an opening 0.15% or  
larger than the respective floor spaces at the top  
or bottom of the door).  
Outdoor unit  
Refrigerant tubing  
Indoor unit  
Most importantly, the multi air conditioner system is  
able to replenish a large amount of refrigerant com-  
pared to conventional individual air conditioners. If a  
single unit of the multi air conditioner system is to be  
installed in a small room, select a suitable model and  
installation procedure so that if the refrigerant acci-  
dentally leaks out, its density does not reach the limit  
(and in the event of an emergency, measures can be  
made before injury can occur).  
In a room where the density may exceed the limit,  
create an opening with adjacent rooms, or install  
mechanical ventilation combined with a gas leak  
detection device. The density is as given below.  
(3) If an indoor unit is installed in each partitioned  
room and the refrigerant tubing is interconnected,  
the smallest room of course becomes the object.  
But when mechanical ventilation is installed inter-  
locked with a gas leakage detector in the smallest  
room where the density limit is exceeded, the vol-  
ume of the next smallest room becomes the object.

Find the space for the installation of the return air grille and  
mark the opening to do. Cut the falseceiling. (fig. 2-2)  
Use rawl plug suitable to the ceiling consistence and four  
M10 threaded bars of suitable length (not supplied). (fig. 2-  
3)  
Mark on the ceiling the holes for the hanging rods, verify the  
distance of the centres. The value included in the brackets  
is referred to the model X18. (fig. 2-4)  
Drill a 80 mm diameter hole, for the passage of refrigeration  
pipework, condensate pipework and electrical cable. Insert  
a PVC pipe in the wall. (fig. 2-5)  
Fig. 2-3  
Secure the unit in position with locknuts and washers, level  
the unit, keeping the right distance from the falseceiling for  
the installation of return air grille. (fig. 2-6)  
Foresee a removable panel of the falseceiling for servicing.  
(fig. 2-7)  
The unit is supplied with PVC hose from the condensate  
pump. Maximum pump lift is 250 mm over the unit. Convoy  
the condensate with a positive slope (min. 1:100) to the out-  
side. The highest point in the condensate pipework should  
be as close to the unit as possible. This prevents a large  
volume of water draining back into the unit when it is  
switched off. (fig. 2-8)  
Convoy the condensate to the outside with a positive slope,  
from a trap at the end if necessary. (fig. 2-9)

There is a duct connection port for drawing in fresh air.  
The supplementary fan motor for outside air intake has to be supplied separately and controlled by a bipolar ON-OFF switch  
with safety fuses.  
Fresh air flow must be about 10% of the total air flow to avoid operating problems and noise.  
Open the knock-out hole , fix a 120 mm flange on the unit and connect the thermically insulated duct.  
Install an outside grille with filter inspection port to prevent dust and leaves from entering and fouling the indoor unit heat  
exchanger.

3. TEST OF THE SYSTEM AND CONTROL OF THE AIR VOLUME TO THE OUTLET GRILLES  
The unit is prearranged to supply an external static pressure  
of about 5 mm. Too high resistances in the air distribution  
system can cause an exceedingly small air volume to the  
outlet grilles.  
This trouble can be solved by increasing the fan speed as  
follows:  
Open the cover of the electrical junction box. Take out the  
booster cable clamped in the box. (fig. 3-1)  
Disconnect the fan motor plug in the electrical box and insert  
the booster cable as a cable extension between the motor  
plug and the socket from the PCB. The external static pres-  
sure will increase to 7 mm w.g. Check static pressure and air  
flow rate on the fan performance graph. (fig. 3-2)

4. ELECTRICAL WIRING  
4-1. General Precautions on Wiring  
(1) Before wiring, confirm the rated voltage of the unit  
as shown on its nameplate, then carry out the  
wiring closely following the wiring diagram.  
(7) Regulations on wire diameters differ from locality  
to locality. For field wiring rules, please refer to  
your LOCAL ELECTRICAL CODES before begin-  
ning.  
(2) Provide a power outlet to be used exclusively for  
each unit, and a power supply disconnect and cir-  
cuit breaker for overcurrent protection should be  
provided in the exclusive line.  
You must ensure that installation complies with all  
relevant rules and regulations.  
(8) To prevent malfunction of the air conditioner  
caused by electrical noise, care must be taken  
when wiring as follows:  
(3) To prevent possible hazards from insulation fail-  
ure, the unit must be grounded.  
(4) Each wiring connection must be done in accor-  
dance with the wiring system diagram. Wrong  
wiring may cause the unit to misoperate or  
become damaged.  
G The remote control wiring and the inter-unit control  
wiring should be wired apart from the inter-unit  
power wiring.  
G Use shielded wires for inter-unit control wiring  
(5) Do not allow wiring to touch the refrigerant tubing,  
compressor, or any moving parts of the fan.  
between units and ground the shield on both sides.  
(9) If the power supply cord of this appliance is dam-  
aged, it must be replaced by a repair shop  
appointed by the manufacture, because special  
purpose tools are required.  
(6) Unauthorized changes in the internal wiring can be  
very dangerous. The manufacturer will accept no  
responsibility for any damage or misoperation that  
occurs as a result of such unauthorized changes.

5. HOW TO PROCESS TUBING  
After  
Before  
The narrow tubing side is connected by a flare nut,  
and the wide tubing side is connected by brazing.  
5-1. Connecting the Refrigerant Tubing  
Use of the Flaring Method  
Many of conventional split system air conditioners  
employ the flaring method to connect refrigerant tubes  
which run between indoor and outdoor units. In this  
method, the copper tubes are flared at each end and  
connected with flare nuts.  
Fig. 5-1  
Flaring Procedure with a Flare Tool  
(1) Cut the copper tube to the required length with a  
tube cutter. It is recommended to cut approx. 30  
50 cm longer than the tubing length you esti-  
mate.  
Copper  
tubing  
(2) Remove burrs at the end of the copper tube with a  
tube reamer or file. This process is important and  
should be done carefully to make a good flare.  
(Fig. 5-1)  
Reamer  
Fig. 5-2  
NOTE  
When reaming, hold the tube end downward and be  
sure that no copper scraps fall into the tube. (Fig. 5-2)  
(3) Remove the flare nut from the unit and be sure to  
mount it on the copper tube.  
Flare nut  
(4) Make a flare at the end of copper tube with a  
flare tool.* (Fig. 5-3)

Flare tool  
NOTE  
Fig. 5-3  
A good flare should have the following characteristics:  
G inside surface is glossy and smooth  
G edge is smooth  
G tapered sides are of uniform length  
12  
Caution Before Connecting Tubes Tightly  
(1) Apply a sealing cap or water-proof tape to prevent  
dust or water from entering the tubes before they  
are used.  
Apply refrigerant  
lubricant here and here  
(2) Be sure to apply refrigerant lubricant to the match-  
ing surfaces of the flare and union before connect-  
ing them together. This is effective for reducing  
gas leaks. (Fig. 5-4)  
Fig. 5-4  
(3) For proper connection, align the union tube and  
flare tube straight with each other, then screw in  
the flare nut lightly at first to obtain a smooth  
match. (Fig. 5-5)  
Flare nut  
Union  
G Adjust the shape of the narrow tube (liquid tube)  
using a tube bender at the installation site and  
connect it to the narrow tubing side (liquid tubing  
side) valve using a flare.  
Fig. 5-5  
Cautions During Brazing  
G Replace air inside the tube with nitrogen gas to  
prevent copper oxide film from forming during  
the brazing process. (Oxygen, carbon dioxide  
and Freon are not acceptable.)  
Torque wrench  
Spanner  
Indoor unit  
G Do not allow the tubing to get too hot during  
brazing. The nitrogen gas inside the tubing  
may overheat, causing refrigerant system  
valves to become damaged. Therefore allow  
the tubing to cool when brazing.  
Outdoor unit  
Fig. 5-6  
G Use a reducing valve for the nitrogen cylinder.  
G Do not use agents intended to prevent the for-  
mation of oxide film. These agents adversely  
affect the refrigerant and refrigerant oil, and  
may cause damage or malfunctions.

G When removing the flare nuts from the tubing con-  
nections, or when tightening them after connecting  
the tubing, be sure to use 2 monkey wrenches or  
spanners as shown. (Fig. 5-6)  
Because the pressure is approximately 1.6 times  
higher than conventional refrigerant pressure, the  
use of ordinary flare nuts (type 1) or thin-walled  
tubes may result in tube rupture, injury, or asphyxi-  
ation caused by refrigerant leakage.  
If the flare nuts are over-tightened, the flare may be  
damaged, which could result refrigerant leakage  
and cause in injury or asphyxiation to room occu-  
pants.  
G In order to prevent damage to the flare caused by  
over-tightening of the flare nuts, use the table  
above as a guide when tightening.  
G For the flare nuts at tubing connections, be sure to  
use the flare nuts that were supplied with the unit,  
or else flare nuts for R410A (type 2). The refriger-  
ant tubing that is used must be of the correct wall  
thickness as shown in the table at right.  
G When tightening the flare nut on the narrow tube,  
use a monkey wrench with a nominal handle length  
of 200 mm.

Tubing Insulation  
Two tubes arranged together  
Narrow tubing  
Wide tubing  
G Thermal insulation must be applied to all unit tub-  
ing, including distribution joint (purchased sepa-  
rately).  
* For gas tubing, the insulation material must be  
heat resistant to 120°C or above. For other tubing,  
it must be heat resistant to 80°C or above.  
Insulation material thickness must be 10 mm or  
greater.  
If the conditions inside the ceiling exceed DB 30°C  
and RH 70%, increase the thickness of the gas  
tubing insulation material by 1 step.

(1) At this time, the refrigerant tubes (and electrical  
wiring if local codes permit) should be taped  
together with armoring tape in 1 bundle. To pre-  
vent the condensation from overflowing the drain  
pan, keep the drain hose separate from the  
refrigerant tubing.

(2) Wrap the armoring tape from the bottom of the  
outdoor unit to the top of the tubing where it  
enters the wall. As you wrap the tubing, overlap  
half of each previous tape turn.

(3) Clamp the tubing bundle to the wall, using 1  
clamp approx. each meter. (Fig. 5-10)  
NOTE

Do not wind the armoring tape too tightly since this  
will decrease the heat insulation effect. Also ensure  
that the condensation drain hose splits away from the  
bundle and drips clear of the unit and the tubing.

5-5. Finishing the Installation  
After finishing insulating and taping over the tubing,  
use sealing putty to seal off the hole in the wall to pre-  
vent rain and draft from entering. (Fig. 5-11)

I Suggerimenti per risparmiare energia  
Non ostruire la presa daria e luscita daria dellunità. In caso di ostruzione,  
lunità non funziona correttamente e può subire dei danni.  
Da evitare  
Non lasciar entrare la luce solare diretta nella stanza. A tale scopo utilizzare parasole,  
tende o persiane. Se le pareti e il soffitto vengono riscaldati dal sole, il raffreddamento  
della stanza richiede più tempo.  
Cose da fare  
Mantenete sempre pulito il filtro dellaria (fare riferimento a Cura e manutenzione). Un  
filtro ostruito compromette il rendimento dellunità.  
Per evitare fughe daria condizionata, tenete chiuse finestre, porte ed altre aperture.  
Mancanza di corrente durante il funzionamento dellunità  
NOTA  
In caso di una temporanea mancanza di corrente, lunità riprende automaticamente a funzionare, al ripristino  
della corrente, con le stesse impostazioni che aveva prima dellinterruzione.
