Persiapan

sambungkan tabung N2, tabung refrigerant & pompa vacuum ke outdoor unit.

4. Installation: Air Tight Test & Vacuum Drying


Persiapan :

sambungkan tabung N2 , tabung refrigerant & pompa vacuum ke outdoor unit.

shutoff valve & valve A~C harus terbuka atau tetutup sesuai dengan tabel

Test press di lakukan hanya pada service port liquid & gas .



Test presst:

test press di papa liquid & gas dengan tekanan 40kg/cm2 or 568Psi (Max.) dengan N2 gas.

test pressure dilakukan 24hrs. Jika tekanan tidak turun sistem tidak bocor

jika tekanan turun,cari kebocoran dan test kembali.

Pemvakuman:

pemvakuman dilakukan pada pipa gas & liquid dengan menggunakan pompa vakum selama 2jam atau lebih samapai mendekati 760mmHg.

biarkan selama 1hr & periksa kembali.

jika tidak ada masalah, tambah refrigerant & check operation.

4. Installation: Additional Refrigerant Charge Additional Refrigerant Charge:

Calculate additional charge amount as below.

Ref: ED34-762; Pg 527




ALWAYS charge using R410A refrigerant gas. (Charge in liq. State ONLY!)

Below is the pre-charge amount of refrigerant in the respective system.

(Kg) Ref: ED34-762; Pg 374






Connect as below & perform manual refrigerant charging from liq. side.

Ref: ED34-762; Pg 543







If additional charge above is not able to be charged fully, perform by field setting (Setting Mode 2 item no. 20).

Ref: ED34-762; Pg 543








Perform Check operation by pressing the button on the outdoor PCB.

Press & Hold for 5sec

Ref: ED34-762; Pg 544








Perform Check operation by pressing the button on the outdoor PCB.

Check operation will last for about 40mins and stops automatically.

Check operation must be performed if not U3 error code will appear.

After Check operation completes, perform test run of the system.
