I bought a new Split AC (1 ton, LG made) and the company sent home a technician to install the unit. The guy arrived and took measurements and I quizzed him a bit about his kit and strangely it doesn't seem to include either a vacuum pump nor a Nitrogen Cylinder.
From what little I know, I thought these two items are essential to commissioning the AC. Am I wrong in assuming this?
Or is there any reasonable way to connect the Indoor and Outdoor units and start things up using the refrigerant provided alone without using a vacuum pump (for evacuation) nor a N2 cylinder (for pressurized leak testing)?
He hasn't started the actual connections yet and I just wanted to be sure the guy knows what he is doing.
