6-2 Protection against contamination
when installing pipes
Protect the piping to prevent moisture, dirt, dust, etc. from
entering the piping.
Note
Exercise special caution to prevent dirt or dust when passing pip-
ing through holes in walls and when passing pipe edges to the
exterior.
6-3 Pipe connection
• Be sure to perform nitrogen permutation or nitrogen blow
when brazing. (Refer to figure 10)
Brazing without performing nitrogen permutation or nitrogen
blow into the piping will create large quantities of oxidized film
on the inside of the pipes, adversely affecting valves and com-
pressors in the refrigerating system and preventing normal
operation.
(Refer to figure 10)
1. Refrigerant pipe
2. Location to be brazed
3. Nitrogen
4. Taping
5. Handy valve
6. Regulator
• The pressure regulator for the nitrogen released when doing
the brazing should be set to 0.02 MPa (about 0.2kg/
cm
2
:
Enough to feel a slight breeze on your cheek).
Note
Do not use anti-oxidants when brazing the pipe joints.
Residue can clog pipes and break equipment.
6-4 Connecting the refrigerant piping
1.
Derection to bring out the pipes
The local interunit piping can be connected either forward or to
the sides (taken out through the bottom) as shown in the figure 11.
(When passing out through the bottom, use the knock hole in the
bottom frame.)
(Refer to figure 11)
1. Left-side connection
2. Front connection
3. Right-side connection
Precautions when knocking out knock holes
• Open knock hole in the base frame by drilling the 4 concave
around it with a 6mm bit. (Refer to figure 12)
(Refer to figure 12)
1. Knock hole
2. Drill
3. Concave section
• Be sure to avoid damaging the casing
• After knocking out the holes, we recommend you remove any
burrs and paint them using the repair paint to prevent rusting.
• When passing electrical wiring through the knock holes, protect
the wiring with a conduit or bushings, making sure not to damage
the wiring.
2.
Removing Pinch Piping
• When connecting refrigerant piping to an outdoor unit, remove
the pinch piping. (Refer to figure 13)
• Pinch piping should be removed using the procedure in the fig-
ure 13.
(Refer to figure 13)
1. Shutoff valve (liquid side · gas side)
2. Service port
3. Pinch piping
4. Procedure 1:
Confirm the shutoff valve is closed.
5. Procedure 2:
Connect a charge hose to the service port of the liquid
side and gas side shutoff valves and remove the gas
from the pinch piping.
6. Procedure 3:
After removing the gas from the pinch piping, dissolve
the brazing using a burner and remove the pinch piping.
Caution
After removing the gass, remove the pinch piping.
Any gas remaining inside may blow off the pinch piping when you dis-
solve the brazing, causing damage.
3.
Connecting refrigerant piping to outdoor units
<In case of single system: 8-12HP type>
(Refer to figure 14)
1. If connected to the front
2. When connected at lateral side (bottom)
3. Remove the shutoff valve cover to connect.
4. Remove the knock hole on the bottom frame and route
the piping under the bottom frame.
5. Gas side shutoff valve
6. Liquid side shutoff valve

14. Punch the knock hole.
15. Gas side piping (field supply)
16. Liquid side piping (field supply)
Processing the Gas side accessory pipe (2)
Only in case of connecting at lateral side, cut the Gas side acces-
sory pipe (2) referring the figure below.
(mm)
<In case of multi system: RXYQ16-36P(E)>
(Refer to figure 15)
1. If connected to the front
2. When connected at lateral side (bottom)
3. Remove the shutoff valve cover to connect.
4. Remove the knock hole on the bottom frame and route
the piping under the bottom frame.

- Note electrical wiring must be done in accordance with the wiring dia grams and the description herein do not operate until refrigerant piping work is completed if operated before complete the piping work the compressor may be broken down never remove thermistor sensor or etc when connecting power wiring and transmission wiring if operated with thermistor sensor or etc removed the compres sor may be broken down this product have reversed phase protection detector that only works when the power is turned on if there exists black out or the power goes on and off which the product is operating attach a reversed phase protection circuit locally running the product in reversed phase may break the compressor and other parts attach the power wire securely introducing power with a missing n phase or with a mistaken n phase will break the unit never connect the power supply in reversed phase the unit can not operate normally in reversed phase if you connect in reversed phase replace two of the 14
- Note make sure the weak electric wiring i e for the remote control ler between units etc and the power wiring do not pass near each other keeping them at least 50 mm apart proximity may cause electrical interference malfunctions and breakage be sure to connect the power wiring to the power wiring termi nal block and secure it as described in 7 5 power wiring connection procedure 14
- Note the above table indicates power specifications for standard combi nations see 2 introduction if using anything other than the above combinations in a multi sys tem calculate using the following procedure minimum circuit amp value add the minimum circuit amp values for each independent unit 14
- Only proceed with wiring work after blocking off all power always ground wires in accordance with relevant local and national regulations this machine includes an inverter device connect earth and leave charge to eliminate the impact on other devices by reducing noise generated from the inverter device and to prevent leaked current from being charged in the outer hull of the product do not connect the ground wire to gas pipes sewage pipes light ning rods or telephone ground wires gas pipes can explode or catch fire if there is a gas leak sewage pipes no grounding effect is possible if hard plastic pip ing is used telephone ground wires and lightning rods dangerous when struck by lightning due to abnormal rise in electrical potential in the grounding be sure to install an earth leakage circuit breaker this unit uses an inverter so install the earth leakage circuit breaker that be capable of handling high harmonics in order to prevent malfunctioning of the earth leakage circuit breaker i 14
