To Operate Pump With an AC Power Source
DANGER: NEVER apply AC voltages directly to the EXTERNAL POWER INPUT receptacle on the front panel.
The application of AC voltages can result in injury and death of the operator and destruction of the
unit. Use only the AC/DC Power Supply/Converter supplied with the unit to power unit from an AC
source.
DANGER: The AC/DC Power Supply/Converter is rated for INDOOR USE ONLY. DO NOT use the AC/DC
Power Supply/Converter in an outdoor environment to either charge the battery or power the
drive. Electrical shock, severe injury and/or death is possible if this warning is ignored.
A. Connect the supplied AC/DC Power Supply/Converter to drive by lifting the EXTERNAL POWER INPUT
(A), receptacle cover and inserting the 2.5 mm coaxial power jack into the receptacle. (See Figure 1.)
B. Connect AC/DC Power Supply/Converter to an AC power source. Place the Power Source Selection
Switch (B), (EXTERNAL/BATTERY) to the "EXTERNAL" position.
C. Place the Mode of Operation Selection Switch (C) (CHARGE/RUN) to the "RUN" position.
D. Select Pump Rotational Direction Selection On/Off Switch (H), CW or CCW. (See Figure 1.) (When changing
directions, turn off the power first, which is the center or OFF position of the Rotational Direction Switch.)
E. Adjust pump flow rate with the 1-turn Speed Control (I), by turning the knob CW to increase flow rate or CCW to
decrease flow rate.
F. To "Prime the Tubing", toggle the "MAX" Switch (J), up or down and hold to make the pump run at maximum
speed.
CAUTION: Immersion or submersion of the unit will result in improper operation and possible damage to the
unit.
Cleaning
Clean exterior and interior surfaces of the housing and control panel using a dry or damp cloth with mild detergent. Never
immerse nor use excess fluid.
Internal Battery
The internal battery is spill-proof and sealed, has no serviceable internal parts or components and is constructed for
years of useful service when maintained properly.
CAUTION: Fully charge the unit before using for the first time. Damage to the internal battery can result if the
battery is in a fully discharged state and operation of the unit is attempted.
A. Fully charge the unit before first use.
B. Store unit at room temperature if possible.
C. Always store the unit in a fully charged condition.
D. The battery will partially self-discharge over time. The rate of self-discharge increases with temperature. It is rec-
ommended that the unit be run for at least 2 hours every six months and then recharged overnight. This will pre-
serve the potential life of the internal battery to its fullest extent.
E. Do not leave the unit on charge for more than 24 hours. Unnecessary extended charging will cause internal heat-
ing and potential premature failure of the battery. The battery will fully charge in 8–12 hours from a fully dis-
charged state. Once the battery has reached full charge, the internal battery charger/regulator circuit will place
the battery in the trickle charge mode to prevent overcharging.
To Charge the Internal Battery From an AC Source
DANGER: NEVER apply AC voltages directly to the EXTERNAL POWER INPUT receptacle on the front panel.
The application of AC voltages can result in injury and death of the operator and destruction of the
unit. Use only the AC/DC Power Supply/Converter supplied with the unit to power unit from an AC
source.
