WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects
before servicing. Follow proper lockout/tagout procedures to
ensure the power can not be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious
injury.
1. Place panel disconnects(s), H/O/A switches, and control power On/Off
switch (if provided) to the "Off" position.
2. Open the panel and visually check components for any shipping damage
and verify that all power leads are secure (see "Tightening Torque Refer-
ence Guide" label on inner panel door).
3. Switch main power supply disconnect to "ON". This will provide power to
the terminal block of the Booster System Control Panel. Verify the power
supply agrees with the Booster System Panel.
IF NOT PROCEEDING WITH START UP AT THIS TIME, DISCONNECT
POWER SUPPLY TO PANEL.
Pump Checkout Procedure
1. Verify electric power and water are available.
2. All valves, including main suction valve and discharge valves must be in
closed position.
3. If unit is in storage for more than 3 months, rotate each pump by hand.
Units should turn freely.
4. Open the main suction valve on inlet to system manifold and check suc-
tion pressure against specifications.
5. Slowly open suction valve to one pump at a time. Check pump units and
fittings for leaks.
6. Vent each pump volute by loosening a pipe plug at the highest point to
assure no air is trapped which would cause seal failure and/or pump
"vapor lock".
7. Slowly open pump discharge valve - one pump at a time. Check fittings
for leaks. DO NOT OPEN MAIN DISCHARGE VALVE (Multi-Purpose
Valve) ON OUTLET OF SYSTEM MANIFOLD AT THIS TIME.
