(2) The cut-off valves are completely closed before ex-work. Before connecting the refrigerant pipe, be
careful to check whether the valves are completely closed.
(3) The connection procedure of refrigerant pipe: first, unscrew the two valves on the outdoor unit and
the pipe-jointing nut on the indoor unit(please save them care fully). Please connect the refrigerant
pipe according to the manual, the pipe-jointing nut should be screwed tightly and no leakage.
Note: you need two wrenches to make balance.
(4) When the connection of refrigerant pipe is finished, before power on the system, you should
vacuum the indoor unit through the maintenance port on the cut-off valves, or open the high-
pressure valve, and exhaust the air through the maintenance port on the low-pressure valve
(closed). It will take about ten seconds. Then screw the maintenance port on tightly.
(When supplement the refrigerant, fill from the maintenance port of the low-pressure valves on
the outdoor unit ).
(5) Open all the valves completely before power on the system, or it will cause low efficiency.
(6) Gas leak check.
(1) Only the correctly installing of indoor and outdoor unit done, can the refrigerant pipe be
connected.

Completely shut the cut-off valves of the outdoor unit (as ex-work status). After the refrigerant pipe
has been connected with both the indoor and outdoor unit, let the air exhaust out from the maintenance
gap on the low-pressure cut-off valves of the outdoor unit. Screw the nuts tightly on the maintenance
gap after the air has been discharged.
you should keep the cut-off valves of the outdoor unit completely opened after you have finished the
above steps (step1 or step 2)

Χρησιµοποιώντας αντλία κενού
(Για την µέθοδο που χρησιµοποιεί βαλβίδα πολλαπλής εισαγωγής, ανατρέξτε στο εγχειρίδιο χρήσης της.)
1. Σφίξτε καλά τα παξιµάδια Α, Β, Γ, ∆ , συνδέστε τον σωλήνα της βαλβίδα πολλαπλής εισαγωγής στην
βαλβίδα χαµηλής πίεσης στην πλευρά του ψυκτικού αερίου.
2. Συνδέστε το σωλήνα µε την αντλία κενού.
3. Ανοίξτε πλήρως µοχλό της βαλβίδας πολλαπλής που έχει συνδεθεί η βαλβίδα χαµηλής πίεσης.
4. Ενεργοποιήστε την αντία κενού για να εκκενώσετε τον αέρα. Μετά την έναρξη της εκκένωσης, χαλαρώστε
ελαφρώς το παξιµάδι της βαλβίδας χαµηλής πίεσης στην πλευρά του ψυκτικού αερίου και ελέγξτε ότι
περνάει ο αέρας. (Ο ήχος της αντλίας κενού θα αλλάξει και ο µετρητής µείγµατος θα δείχνει 0 αντί για
µείον.)
5. Μετά το τέλος της εκκένωσης, κλείστε καλά την βαλβίδα
(στην βαλβίδα πολλαπλής) στην βαλβίδα χαµηλής πίεσης και
σταµατήστε την λειτουργία της αντλίας κενού.
Εκκενώστε για περίπου 15 λεπτά και ελέγξτε ότι ο µετρητής
µείγµατος δείχνει -76cmHg ( -1 x 105Pa ).
6.Στρίψτε το στέλεχος της βαλβίδας Β κατά περίπου 45°
δεξιόστοφα για 6-7 δευτερόλεπτα αφού ξεκινήσει να βγαίνει
αέριο κλείστε και πάλι τη βαλβίδα.Βεβαιωθείτε ότι ο µετρητής
πίεσης δείχνει µετρήση λίγο µεγαλήτερη από την
ατµοσφαιρική πίεση.
7.Αφαιρέστε το σωλήνα εκκένωσης από την βαλβίδα χαµηλής
πίεσης.
8. Ανοίξτε πλήρως τα στελέχη των βαλβίδων Β και Α
9. Σφίξτε το κάλυµµα των βαλβίδων.
Βεβαιωθείτε ότι ο αγωγός αποστράγγισης είναι συνδεδεµένος µε την εξωτερική µονάδα µε καθοδική
φορά.
Οι σκληροί σωλήνες PVC (µε εξωτερική διάµετρο 26mm) που διατίθενται στο εµπόριο, είναι κατάλληλοι
για την κάλυψη του συσκευασµένου εύκαµπτου σωλήνα αποστράγγισης.
Ενώστε τον εύκαµπτο σωλήνα αποστράγγισης µε τον αγωγό αποστράγγισης και στερεώστε τα µε ταινία.
Εάν η σύνδεση του αγωγού αποστράγγισης πρέπει να είναι σε εσωτερικό χώρο, για την αποφυγή
συµπύκνωσης σταγονιδίων από την εισαγωγή αέρα, καλύψτε τον αγωγό µε µονωτικό υλικό ( πολυεθυλένιο
µε ειδικό βάρος 0.03 και πάχος τουλάχιστον 9mm) , και στερεώστε τα µε ταινία.
Μετά στην σύνδεση του αγωγού αποστράγγισης ελέγξτε ότι το νερό εξέρχεται από τον αγωγό σωστά και
δεν υπάρχουν διαρροές.
Ο αγωγός ψυκτικού και ο αγωγός αποστράγγισης θα πρέπει να είναι µονωµένοι ώστε να αποφευχθεί η
συµπύκνωση υγρασίας και η δηµιουργία σταγονιδίων νερού.
