The manual doesn't mention doing a pressure test (other than observing vacuum is held) I called Senville tech support and they told me I need to have pressures checked (125 psi cooling mode, 400 psi heating mode)

What Size Mini Split Should You Put In Your Garage (Based On Size)

So what doesn't leak at 50 PSI isn't assured to not leak at any pressure In heat mode, the highest pressure an R410A mini split can even reach to around 500 psi So wondering how much PSI should I be using for the nitrogen pressure test

Fujitsu Introduces MiniSplit Medium Static Pressure Duct Units. So, the pressure test of an R410A mini split should be around 500 psi with a maximum test pressure of 600 psi, subject to the safe working pressure of the copper pipes used. 10 posts · Joined 2018 Add to quote; Only show this user #1 · Nov 7, 2018

Mini Split Placement Where Should You Install Your Mini Split?. And normal operating conditions can easily be 450-500 PSI I'm going to be installing two mini split heat pumps for my workshop and wonder if air can be used to pressure test instead of nitrogen? My reasoning is that the line sets are open to the air during installation and then all of the gas is purged during vacuum pumping anyway, what's the risk of using compressed air pressure instead of Nitrogen for leak testing?
