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/installer
provides an adequate draining system to
avoid damage in case of leakage, particularly 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. The pump should be installed with horizontal
suction port and vertical discharge port; and
as close as possible to the liquid source.
4. When use with water heaters, 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. The pump has a built-in check valve. Please
do not install any other valve on the suction.
7. For TQ1500/2200/3700, Please cut out the
center of the rubber gasket inside the inlet
and outlet flanges as it will block the water
flow.

8. When performing regular maintenance, the
prime cover has to open in order to check
the condition of the check valve. DO NOT
apply any bonded material (such as silicon,
glue etc) to seal the chamber cover (see
drawing below).
IV. Piping
1. The suction line should be installed as short
and straight as possible, with a minimum of
bends. The internal diameter of the suction
pipe must be equal to, or greater than the
ports of the pump.
2. The connection between the suction line and
pump must be airtight, and the suction pipe
must be positioned so it has an upward
slope to the pump (thus avoiding the
formation of air pockets).
3. When used on a suction lift, a foot valve
should be fitted on the suction line, below
the liquid level.
4. If hose is used as the suction pipe, it must
be non-collapsible.
5. To minimize pressure drop, the discharge
pipe should be at least the same size as the
discharge port of the pump.
6. For long suction pipes or high suction lifts
over 13 ft, the suction pipe should be of
greater diameter than the suction port.
7. Ensure all connections are completely
sealed using thread tape only.
V. Electrical connection
This mark located outside the
connection box is a warning for an
electrical hazard.
1. Ensure the mains voltage is the same as the
value shown on the motor plate and that the
pump is safely connected to ground/earth.
