7. Drain the pump.
If this pump is used for volatile and/or flammable liquids, be certain proper safety practices are followed before op erating or servicing the pump. Provide adequate ventilation, prohibit smoking, wear static‐resistant clothing and shoes. Clean up all fuel spills immedi ately after occurrence.
Do not install and operate a non‐explo sion proof motor in an explosive atmo sphere. Install, connect, and operate the motor in accordance with the Na
PAGE A - 1SAFETY
tional Electric Code and all local codes. If there is a conflict between the instruc tions in the manual accompanying the unit and the National Electric Code or the applicable local code, the National or local code shall take precedence.
If this pump is used with volatile and/or flammable liquids, overheating may produce dangerous fumes. Take pre cautions to ensure the area surrounding the pump is adequately ventilated. Al low the pump to cool and use extreme caution when venting the pump, or when removing covers, plates, plugs, or fittings.
Use lifting and moving equipment in good repair and with adequate capacity to prevent injuries to personnel or dam age to equipment. Suction and dis charge hoses and piping must be re moved from the pump before lifting.
0 SERIESOM-01087
Do not operate the pump against a closed discharge valve for long periods of time. If operated against a closed dis charge valve, pump components will deteriorate, and the liquid could come to a boil, build pressure, and cause the pump casing to rupture or explode.
Overheated pumps can cause severe burns and injuries. If overheating of the pump occurs:
1. Stop the pump immediately.
2. Ventilate the area.
3. Allow the pump to completely cool.
4. Check the temperature before opening any covers, plates, gauges, or plugs.
5. Vent the pump slowly and cau tiously.
6. Refer to instructions in this manual before restarting the pump.
Do not remove plates, covers, gauges, pipe plugs, or fittings from an over heated pump. Vapor pressure within the pump can cause parts being disen

INSTALLATION - SECTION B

Review all SAFETY information in Section A.
Since pump installations are seldom identical, this section offers only general recommendations and practices required to inspect, position, and ar range the pump and piping.
Most of the information pertains to a standard static lift application where the pump is positioned above the free level of liquid to be pumped.
If installed in a flooded suction application where the liquid is supplied to the pump under pressure, some of the information such as mounting, line
OUTLINE DRAWING
configuration, and priming must be tailored to the specific application. Since the pressure supplied to the pump is critical to performance and safety, be sure to limit the incoming pressure to 50% of the maximum permissible operating pressure as shown on the pump performance curve.
For further assistance, contact your Gorman‐Rupp distributor or the Gorman‐Rupp Company.
Pump Dimensions
See Figure 1 for the approximate physical dimen sions of this pump.
Figure 1. Pump Model 02C3-B
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested be fore shipment from the factory. Before installation, inspect the pump for damage which may have oc curred during shipment. Check as follows:
a. Inspect the pump and engine for cracks,
dents, damaged threads, and other obvious damage.
b. Check for and tighten loose attaching hard
ware. Since gaskets tend to shrink after dry ing, check for loose hardware at mating sur faces.
c. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties indicated.
d. Check levels and lubricate as necessary. Re
fer to LUBRICATION in the MAINTENANCE
PAGE B - 1INSTALLATION
OM-01087 0 SERIES
AND REPAIR section of this manual and per
form duties as instructed.
e. If the pump and engine have been stored for
more than 12 months, some of the compo nents or lubricants may have exceeded their maximum shelf life. These must be inspected or replaced to ensure maximum pump serv ice.
If the maximum shelf life has been exceeded, or if anything appears to be abnormal, contact your Gorman‐Rupp distributor or the factory to deter mine the repair or updating policy. Do not put the pump into service until appropriate action has been taken.
POSITIONING PUMP
Use lifting and moving equipment in good repair and with adequate capacity to prevent injuries to personnel or dam age to equipment. Suction and dis charge hoses and piping must be re moved from the pump before lifting.
Lifting
The pump may have to be supported or shimmed to provide for level operation or to eliminate vibra tion.
SUCTION AND DISCHARGE PIPING
Pump performance is adversely effected by in creased suction lift, discharge elevation, and fric tion losses. Contact the factory to be sure your overall application allows pump to operate within the safe operation range.
Materials
Either pipe or hose maybe used for suction and discharge lines; however, the materials must be compatible with the liquid being pumped. If hose is used in suction lines, it must be the rigid‐wall, rein forced type to prevent collapse under suction. Us ing piping couplings in suction lines is not recom mended.
Line Configuration
Keep suction and discharge lines as straight as possible to minimize friction losses. Make mini mum use of elbows and fittings, which substan tially increase friction loss. If elbows are necessary, use the long‐radius type to minimize friction loss.
Connections to Pump
Pump unit weights will vary depending on the mounting and drive provided. Check the shipping tag on the unit packaging for the actual weight, and use lifting equipment with appropriate capacity. Drain the pump and remove all customer‐installed equipment such as suction and discharge hoses or piping before attempting to lift existing, installed units.
The pump assembly can be seriously damaged if the cables or chains used to lift and move the unit are improperly wrapped around the pump.
Mounting
Locate the pump in an accessible place as close as practical to the liquid being pumped. Level mount ing is essential for proper operation.
Before tightening a connecting flange, align it ex actly with the pump port. Never pull a pipe line into place by tightening the flange bolts and/or cou plings.
Lines near the pump must be independently sup ported to avoid strain on the pump which could cause excessive vibration, decreased bearing life, and increased shaft and seal wear. If hose‐type lines are used, they should have adequate support to secure them when filled with liquid and under pressure.
Gauges
Most pumps are drilled and tapped for installing discharge pressure and vacuum suction gauges. If these gauges are desired for pumps that are not tapped, drill and tap the suction and discharge lines not less than 18 inches (457 mm) from the suction and discharge ports and install the lines. Installation closer to the pump may result in erratic readings.
