We would like to start this task on Wednesday, 09/10 at 0930. We will start in B67. Pumps will be placed in Hand as needed so flow will not be affected. System temperature may drop below normal setpoint (95F) when control valves are stroked to full open given there is little (or no) heat load on the system.
