Preparation for initial start-up

Contact your BeaconMedæs representative for start up assistance.
B.3.2 Liquid Compressant (Seal Liquid)
Proper operation of the vacuum pump requires that liquid compressant (seal liquid) be supplied at the proper rate of
flow. The ideal liquid compressant is fresh water at 60°F (15°C). The seal liquid supply flow rates should be as
specified in Table B-1. Variations in the flow rate of ±25 percent will not damage the vacuum pump, but wide
variations may decrease vacuum pump capacity. See Figure 2-1 for recommended piping connections for the seal
liquid supply.
The seal liquid flow must be started before starting the pump drive
motor, even if the pump is only being operated to check the direction of
B.3.3

Draining and Flushing

Before starting the vacuum pump, remove the drain plug (22, Figure 9-1) from the vacuum pump. Open the shut-off
valves for the seal liquid supply and the initial prime bypass. Allow the seal liquid to flow until there is a clear flow
from all drains. Although the vacuum pump is flushed with inhibiting oil prior to shipment, a light film of rust may
form before installation is complete. This film will disappear after the vacuum pump shaft has been manually
rotated a few times. Close the shut-off valve for the initial prime bypass only. Reinstall the drain plug using a pipe
thread compound.
B.3.4

Preliminary Inspection

Perform the following preliminary inspections before starting the vacuum pump.
Perform all of the following steps in order to ensure personnel safety and
a. Isolate all power sources to the motor to make certain no accidental starting occurs.
b. Inspect the pump to make certain that the drain plug has been installed.
c. Inspect all piping to make certain that proper connections have been made to the pump and its basic
system in accordance with the BeaconMedæs installation drawing(s) supplied with your system.
