The Robinair Cool Tech 34700Z refrigerant recovery/recycle machine is designed to recover and recycle refrigerant from air conditioning and refrigeration systems. If the machine is losing refrigerant during the vacuum cycle, it could be caused by a few different issues. Here are a few possibilities:
Leaks in the hoses or fittings: The hoses and fittings on the machine may be leaking refrigerant, causing it to lose pressure during the vacuum cycle. Check for any visible leaks and replace or repair any damaged or worn hoses or fittings.
Leaks in the machine: The machine itself may be leaking refrigerant. Check for any visible leaks and replace or repair any damaged or worn parts.
Incorrectly set vacuum pressure: The vacuum pressure may be set too high, causing the machine to lose refrigerant during the vacuum cycle. Consult the manual and make sure the pressure is set correctly.
Clogged filters: The filters in the machine may be clogged, preventing it from holding a vacuum and causing it to lose refrigerant during the vacuum cycle. Clean or replace the filters.
Incorrect vacuum pump oil level: The vacuum pump oil level may be too low, preventing the pump from creating a strong enough vacuum to hold refrigerant. Check and add vacuum pump oil as needed.
It's best to consult the manual or a professional technician for help. They will be able to diagnose the problem and recommend the appropriate course of action. It's important to note that not addressing this issue can cause further damage to the machine, so it's best to have it repaired as soon as possible.
