Hi. I've just purchased the 4CFM model. What adapter do I need to connect to a Midea mini split to vacuum the refrigerant lines please? Do you supply these adapters?

Answer This Question

Adapters not provided. Both the diameter of the hose and the inlet nozzle of the vacuum pump are 1/4" SAE. You need to know the size of the interface on the split machine to prepare the conversion joint. It is convenient for product connection.

This pump have a one way on the pipe for oil ,I mean the oil from pump is going back in the pipe when I turn off the pump ,and I did receive oil for this pump,my question is what tipe of oil is it is mineral or synthetic?

Answer This Question

This issue is caused by a failure of the anti-oil-return valve on the vacuum pump's intake port. You can resolve the oil return problem by replacing the intake port assembly. The oil is synthetic; we recommend using a pump lubricant with a viscosity grade of 68. If this answer does not resolve your current issue, please contact us again for assistance.
