On Tuesday it was noted that evaporator 1 was not pumping down properly. It was vented and the seal & seal face wiped with a cloth. The initial pump
down rate was faster, however after 48 hrs, it has still not pumped down to appropriate levels.
Thursday, March 21, 2019, 08:59: IV1 closed & TP1 off. |
