TQ Series Instruction Manual
Please read all instructions carefully before installing your new systems, as failures
caused by incorrect installation or operation are not covered by the warranty.
I. Product
The TQ series are designed for the pumping of non-aggressive water, or water not
containing solid particles.
II. Operating conditions:
1. Ambient temp: Max. +104ºF (40ºC)
2. Liquid temp: +39ºF (4ºC) ~ +104ºF (40ºC) Max.
3. System pressure: Max. 120 PSI
4. Relative humidity: Max. 85% (RH)
III. Installation
1.The pump foundation should be rigid
enough to absorb any vibration from the
motor, and the pump should be securely
bolted to the foundation.
2. It is recommended that the plumber/install-
er provides an adequate draining system to
avoid damage in case of leakage, particu-
larly when installed indoors. When it is
installed outside, it should be covered by a
weather-proof housing, well ventilated to
allow motor heat to escape.
3. Connect the suction pipe to the side and
discharge pipe on the top. (See Fig.1)
4. When it is installed with water heater, a
check valve should be installed between
pump (discharge) pipeline and water
heater (suction) to avoid high-pressure
steam backflow.
5. It is required to shut off the pump when
the liquid source is unavailable; although it
has the dry run cut off function.
6. Regular maintenance requires to open the
prime cover in order to access the check
valve. DO NOT apply any bonded material
(such as silicon, glue etc) to seal the
chamber cover (See Fig.2).
