Discharge Vibrasorber
Removal
1. Recover the refrigerant charge.
2. Heat the connections on the vibrasorber until
the vibrasorber can be removed.
Installation
1. Prepare the vibrasorber and tubing fittings by
cleaning thoroughly.
2. Solder the vibrasorber connections.
3. Pressurize the system and test for leaks. If no
leaks are found, evacuate the system.
4. Charge the unit with the proper refrigerant and
check the compressor oil level.
In-Line Condenser Check Valve
This unit uses an in-line condenser check valve.
The in-line check valve is not repairable and must
be replaced if it fails. A heat sink must be used on
the in-line check valve when it is being soldered
in place to prevent damage to the neoprene seal.
