10. CHECKING OF DEVICE AND INSTAL-
LATION CONDITIONS
Be sure to check the followings.
For those doing electrical work
1.
Make sure there is no faulty transmission wiring or loosing of a nut.
See “7-4 Transmission Wiring Connection Procedure”.
2.
Make sure there is no faulty power wiring or loosing of a nut.
See “7-5 Power Wiring Connection Procedure”.
3.
Has the insulation of the main power circuit deteriorated?
Measure the insulation and check the insulation is above regular
value in accordance with relevant local and national regulations.
For those doing pipe work
1.
Make sure piping size is correct.
See “6-1 Selection of piping material and Refrigerant branch-
ing kit”.
2.
Make sure insulation work is done.
See “9. PIPE INSULATION”.
3.
Make sure there is no faulty refrigerant piping.
See “6. REFRIGERANT PIPING”.
11. ADDITIONAL REFRIGERANT
CHARGE AND CHECK OPERATION
The outdoor unit is charged with refrigerant when shipped from the factory,
but depending on the size and length of the piping when installed, it may
require additional charging.
For charging the additional refrigerant, follow the procedure in this chapter.
And then carry out the check operation.
11-1 Before working
[About the refrigerant tank]
Check whether the tank has a siphon pipe before charging and place
the tank so that the refrigerant is charged in liquid form.
(See the figure below.)
Note
• Always use the proper refrigerant (R410A). If charged with the
refrigerant containing an improper material, it may cause an
explosion or accident.
• R410A is a mixed refrigerant, so charging it as a gas will cause
the refrigerant composition to change, which may prevent normal
operation.
[Shutoff valve operation procedure]
When operating the shutoff valve, follow the procedure instructed below.
Note
• Do not open the shutoff valve until “10. CHECKING OF DEVICE
AND INSTALLATION CONDITIONS” are completed. If the shutoff
valve is left open without turning on the power, it may cause refrig-
erant to buildup in the compressor, leading insulation degradation.
• Be sure to use the correct tools.
The shutoff valve is not a back-seat type. If forced it to open, it
might break the valve body.
• When using a service port, use the charge hose.
• After tightening the cap, make sure no refrigerant gas is leaking.
Tightening torque
The sizes of the shutoff valves on each model and the tightening
torque for each size are listed in the table below.
<Size of Shutoff Valve>
(Refer to figure 28)
1. Service port
2. Cap
3. Hex holes
4. Shaft (valve body)
5. Seal section
To open
1.
Remove the cap and turn the shaft counterclockwise with the
hexagon wrench (JISB4648).
2.
Turn it until the shaft stops.
3.
Make sure to tighten the cap securely.
(For the tightening torque, refer to the item <Tightening Torque>.)
To close
1.
Remove the cap and turn the shaft clockwise with the hexagon
wrench (JISB4648).
2.
Securely tighten the valve until the shaft contacts the main body seal.
3.
Make sure to tighten the cap securely.
(For the tightening torque, refer to the item <Tightening Torque>.)
<Tightening torque>
With siphon pipe
Other tanks
Stand the tank upright and charge.
(The siphon pipe goes all the way inside,
so the tank does not need be put
upside-down charge in liquid form.)
Stand the tank upside-down and charge.
