Daikin RZQ45KCVJK [22/64] 4 precautions when adding r410a

21 English

When re-charging refrigerant, follow the procedure below.

1. Recover refrigerant until the gauge pressure from the refrigerant recovery port drops below 0.09 MPa

(gauge pressure : – 0.011 MPa).

2. Perform vacuum drying from the same refrigerant recovery port using a vacuum pump.

3. Charge the refrigerant from the service port of the liquid-side stop valve when re-charging refrigerant.

8-4 PRECAUTIONS WHEN ADDING R410A

• Before filling, check whether the cylinder has a siphon attached or not. (It should have something like “liquid

filling siphon attached” displayed on it.)

• To prevent entry of any impurities and insure sufficient pressure resistance, always use the special tools

dedicated for R410A.

• The

refrigerant should be charged from the service port of the liquid-side stop valve.

〈

CAUTION

〉

To plumbing persons

• After completing installation, be sure to open the valves.

(Operating the unit with the valve shut will break the compressor.)

• Do not allow refrigerant to escape into the atmosphere recklessly for earth environment protection.

Filling a cylinder with an attached siphon

Stand the cylinder upright

when filling.

(There is a siphon pipe inside,

so the cylinder need not be

upside-down to fill with liquid.)

Filling other cylinders

Stand the tank upside-

down and charge.

(Turn the cylinder upside-

down when filling.)
