ST-3050D SUBMERSIBLE PUMP RULES FOR SAFE OPERATION

ALWAYS make sure that electrical circuits are properly grounded per the National Electrical Code (NEC) and local codes before operating pump. Severe injury or death by electrocution can result from operating an ungrounded pump.

NEVER use this pump to remove water from a swimming pool when people are in the water.

ALWAYS be sure the operator is familiar with proper safety precautions and operations techniques before using submersible pump.

ALWAYS check pump oil level only when pump is cool. Expansion due to heat may cause hot! oil to spray from the oil plug when the oil plug is removed.

DO NOT attempt to thaw-out a frozen pump by using a torch or other source of flame. Application of heat in this manner may heat the oil in the seal cavity above the critical point, causing pump damage.

DO NOT pump water greater than 104 degrees Fahrenheit. Also DO NOT pump liquids containing acid or alkali.

ALWAYS check the dual voltage connection inside the pump for proper voltage setting.

ALWAYS check strainer before pumping. Make sure strainer is not clogged. Remove any large objects, dirt or debris from the strainer to prevent clogging.

ALWAYS use a large basket strainer when pumping water that contain large debris.

ALWAYS flush pump (clean) after use when pumping water concentrated with heavy debris. It is very important to always flush the pump before turning it off to prevent clogging.

ALWAYS store equipment properly when it is not being used. Equipment should be stored in a clean, dry location out of the reach of children.

ALWAYS read, understand, and follow procedures in Operator’s Manual before attempting to operate equipment.

Maintenance Safety

NEVER lubricate components or attempt service on a running machine.

ALWAYS allow the machine a proper amount of time to cool before servicing.

Keep the machinery in proper running condition.

Fix damage to the machine immediately and always replace broken parts.

. Emergencies

ALWAYS know the location of the nearest fire extinguisher.

ALWAYS know the location of the nearest and first aid kit.

In emergencies always know the location of the nearest phone or keep a phone on the job site. Also know the phone numbers of the nearest ambulance, doctor and fire department. This information will be invaluable in the case of an emergency.
