Condenser Coil Connection The condenser coil may contain refrigerant or nitrogen or it could be empty. Check at the access valve with a leak detector to confirm the contents. If refrigerant, it will be R-404A and you can connect the headmaster kit. If it is not refrigerant, purge it and then evacuate the coil. Then add a small amount of R-404A before connecting the headmaster kit. If it is empty, evacuate it, add some R-404A and check for a leak. If no leak is found connect the headmaster kit.
