INSTALLATION
01 Mar 12 3-5
ACD-1500Degasser
VENT LINE AND DISCHARGE DUCT
Vent Line
1. Connect a 4-1/2” (114mm) ID vent line to the exhaust fan outlet. The vent line flange must
have a four-bolt 8-1/2” (38mm) diameter pattern. The vent line must be long enough to convey
the discharged gas to a safe area.
2. The vent line should be supported independently. Any elbows should be located at least two
fan wheel diameters from the exhaust fan.
Discharge Duct
If degassed mud is to be conveyed away from the degasser, connect a 15” x 22-1/2” (381mm x
572mm) duct to spray tank outlet. The duct should slope downward to the receiving tank to
facilitate flow away from the degasser.
ELECTRIC POWER CONNECTIONS
WARNING! TO AVOID SERIOUS PERSONAL INJURY BE SURE POWER TO
EQUIPMENT IS L
OCKED OUT, TAGGED OUT, AND DE-ENERGIZED BEFORE
BEGINNING ELECTRICAL INSTALLATION.
WARNING! MOTOR MUST BE OPERATED AT THE DESIGNATED SUPPLY
VOLTAGE AND FREQUENCY.
WARNING! A FUSED
-DISCONNECT PRIMARY POWER SUPPLY WITH
SUFFICIENT INTERRUPTING CAPACITY T
O CLEAR THE MAXIMUM FAULT
CURRENT CAPABILITY OF THE SYSTEM IS REQUIRED.
WARNING! ELECTRICAL CONNECTIONS MUST BE MADE IN ACCORDANCE
WITH ALL APPLICABLE
NATIONAL AND LOCAL CODES. FAILURE TO
COMPLY MAY RESULT IN AN UNSAFE CONDITION THAT COULD INJURE
PERSON
NEL OR DAMAGE EQUIPMENT. ENSURE THAT ALL ELECTRICAL
AND CONDUIT CONNECTIONS ARE SECURE.
The electrical connections should be performed only by trained, qualified personnel familiar with
high-voltage applications and knowledgeable of all applicable state or local codes for installation
of industrial equipment. A fused disconnect is required for primary power supply. The fused
disconnect and wiring to the equipment shall be suitably sized and in accordance with all
applicable national and local codes.
The degasser is factory-wired to operate on three-phase power at the power configuration
specified by the customer. If the degasser is not equipped with a Derrick-supplied electrical
control panel, electrical connections are terminated at the main drive motor and exhaust fan
motor. The customer must then bring power to the motors either from a starter box or other supply
source.
If degasser is equipped with a Derrick-supplied electrical control panel, the incoming supply
connections are shown on the wiring schematic in Section 8.
Following are general electric power connection requirements:
1. Install a fused disconnect device having sufficient interrupting capacity to clear the maximum
fault current capability of the power supply system.
