Construction
MRH-1 hose construction
The MRH-1 hose has a protective layer, a reinforcing layer and an inner layer that limits refrigerant permeation. The connection nuts are made of brass.
Set contents
Each MRH set contains three hoses: yellow, red and blue.
Connection
- 01Check the model designation and select the connections according to the technical specifications table.
- 02Check the condition of the hoses and connections before connecting them.
Connect the hoses according to the instructions for the instrument being connected.
Operation
Models without valves do not shut off flow through the hose. The ball valve on the CV60° variant is used to open and shut off flow. The SV service valves shut off flow and allow the hose to be disconnected with less refrigerant loss. Closing the valve alone does not remove refrigerant or pressure trapped in the hose.
Finishing work
- 01If refrigerant remains in the hose, recover it using a refrigerant recovery machine.
- 02Make sure that the section being disconnected is no longer under pressure, and disconnect the hoses.
