Use safety equipment necessary to manipulate electricity.
•
Use appropriate signs in areas where electrical equipment is exposed.
•
The pump must be de-energized and secured to prevent startup before starting any work
of electrical equipment.
•
Use the right wire number according to the motor voltage and amperage.
•
Follow diagram connections shown on the motor nameplate; check the motor installation
manual for any questions.
•
Isolate and protect the terminal ports and connections.
•
Make sure the rotation of the pump is correct.
•
The motor of your pump has been tested and was selected to meet the requirements of a
specific application. The motor amperage consumption should be within the range indicated
on the motor nameplate for a proper operation.
•
The user is responsible for the safety and proper operation of equipment when special and
others motors are used (not supplied by Q-Pumps).
Temperature
The QTS Series are designed to work in a normal temperature range between -40 °C (-40 °F) and
100 °C (212 ° F). Be careful when touching the body and bearing housing to avoid burns when
the temperature rises. If the application requires a higher temperature range please contact
Q-Pumps to be advised about this case.
Moving Parts
The principle of operation of the QTS Series is by the turning of a pair of synchronized rotors
which can trap any foreign object and get stuck due to an improper equipment operation.
Never operate the pump without assuring thet the front cover is properly in place.
The bearing housing contains rotating parts; never operate the pump without the gear case.
Watch precautions with free turning shafts of drive elements when not properly coupled to
the pump. Likewise, do not operate the pump without the coupling guard placed in position.
Handling the Pump
Carefully transport the equipment avoiding contact, drops or damage. To prevent any of these
situations the QTS Series are provided with an eye bolt located on the bearing housing for lifting.
In the same way, gear motors and motors have an eye bolt (or at least one hole for using this
part) located in the body.
