Where is your source. I have not found this. I see it is supposed to be found in the Clavicula Salomonis, but I do not find it.
As for arzl in Enochian, this is not the being in clavicula salomonis.
The upper subangle of the eastern tablet is not the same at all. This starts with the first five letters of the tablet, but I will reproduce the whole subangle to make it clear, as every book fails to give correct instruction, abnd has provokedf all matter of idiocy in the name of "Enochian Magic." I will not address the use and deriving of cacodaemons.

The bolded cross is bound to the cross of compelling to appearance and commanding to action, it is not applied here.
The name rZla pronounced "Urz-la" is the first name of that subangle.
These same letters pull forth three others names by permuting them.
These four names and their pronunciations are thus:
r Z l a (Urz-la)
Z l a r (Zal-ar)
l a r Z (la-rz)
a r Z l (ar-zel)
Each of these names is relevant to each of the names pulled from the squares below the arms of the bold cross.
rZla is the name by which cZns, Znsc, nscZ, and scZN appear.
Zlar is the name by which ToTt, oTtT, TtTo, and tTot appear.
larZ is the name by which Sias, iasS, asSi, and sSia appear.
arZl is the name by which fmnd, mndf, ndfm, and dfmn appear.
These four are ruled by taking the letter from the black cross (e) and appending it to the name of the first order of these four permutations.
So erZla (Ehr-zla) is the name of God that rules rZla, Zlar, larZ, and arZl.
The two names of the cross are names of God. Idoigo to make them appear, and Ardza to make them do as commanded.
So a sample invocation of say, cZns (see-zohd-en-ess) woould look like this:
In the name of Oro Ibah Azozpi, the three great names upon the banners of the east born by the servants of god who come with streaming banners and issuing trumpets, and with the authority of Bataiva, Great King of the East, who doth lead the procession of all spirits holy and sanctified in the kingdom of the East, and of the Aires in the East: I do call thee, even as you hearken to the lord God called of you Erzla, I do call you urzla, I call upon you to call upon to cause cZns to appear in the name Idiogo, and to answer my petitions in the name Ardza. Call forth that which you have been given charge to, to administer the healing and medicine concealed in the mysteries of his creation.
You Urzla, I call in the name of your God Erzla to bring forth your charge cZns to appear in the name of Idoigo, and to answer my petitions in the name Ardza, and to be agent of healing and dispenser of the medicine and knowledge of medicine and herbs.
And should it be so severe a case as cause may need I even charge and petition you to bring forth xcZns* (cha-see-zohd-en-ess) should his attendance be necessary!
*this name is formed by adding the x or exarp to the cZns. the X is a harsh like "ch" in the scottish "loch".
The part bolded can be recited over and over ringing a bell (my own way to punctuate the statement and send the request). The italicized section is for if the preliminary incovation is insufficient or if the ailment is believed to be incurable.
As you can see, this is NOT Arzel from the Clavicula, or NAP. This is a spirit which holds sway over four specific angels with agency of healing, and knowledge of medicine and herbs.
And my reference is TFR pages 179 and 180.
I form the light, and create darkness: I make peace, and create evil: I YHVH do all these things.
