Installation / Operation 5
For parts or assistance, call Flotec Customer Service at 1-800-365-6832
To reduce friction losses to a minimum, inlet (suction)
line should be short and have as few elbows as possible.
Size the inlet according to the chart below:
An inlet strainer will prevent suspended debris from clog-
ging pump.
The internal running surfaces of the pump and seals
require water lubrication for good, consistent operation.
Allowing pump to run dry will severely damage pump
and seals.
Install a pressure gauge in pump inlet line. Keep at least
two pounds per square inch pressure (2 PSI) in inlet line
whenever pump is operating. If this is not possible, con-
sult customer service representative.
LUBRICATION
It is not necessary to lubricate pump or motor. The motor
is equipped with sealed ball bearings, lubricated for the
life of the bearing. The mechanical shaft seal in the
pump is self-lubricating and requires no adjustment.
Disassemble pump to replace seal (See “Maintenance”,
Pages 8 and 9).
OPERATION
NOTICE: Observe the following precautions when oper-
ating the pump:
1. Keep the motor dry! Do not direct stream from pump
discharge onto the motor!
2. Hazardous pressure. Do not run the
pump with discharge shutoff, as hose may burst or
pump may be damaged due to high temperatures.
3. Do not use a standard trigger gun with this pump.
Use only trigger guns with an automatic weeping fea-
ture. These are available as accessories and are pro-
vided with three nozzles. The smallest nozzle restricts
the flow, allowing use of a smaller water source. The
two larger nozzles are used if the water source will
supply the pump’s full capacity.
4. Do not run pump dry; to do so may damage the seal.
5. To avoid internal damage to pump, do not operate
with water temperature above 175 degrees F.
