Please study all instructions carefully
before installing your new system, as
failures caused by incorrect installation and
operation are not covered by the warranty.
1.1 OPERATION
The electronic controller orders the pump
start and stop when opening or closing tap
or valve of the system. The controller can
keep a constant pressure and water flow in
the system as long as any tap in the system
during the pump's operation.
1.2 CONSTRUCTION CHARACTERISTICS
-Special non return valve to avoid surges
-Security system avoiding the pump dry run
without water.
-Pressure gauge
-Manual start switeh(RESET)
-Tension LED (POWER)
-Pump-working LED(ON)
-Security system LED (FAILURE)

2. Installation
2.1 Installation site
2.1.1. Choose a site with sold foundation,
dry and good ventilation. Please provide
accessible space around the pump and
leave at least 12"(30cm ) clearance
between your motor end to the wall.
2.1.2. The Walrus TS400C/TS800C pumps
are for indoor use only. When used
outdoors, the pump should be in an
enclosure which is out of direct sunlight,
water proof, frost free and has adequate
ventilation. Make sure the enclosure is
compliant with local regulations.
2.1.3. Please install the pump as close to
water source as possible. The long suction
pipes may cause pressure loss.
2.1.4. Ensure all connections are completely
sealed using thread tape only. An air leak
on the suction may cause your pump
running without discharge flow.
2.1.5. Make sure the environment of your
pump site free from abrasive liquid, PVC,
metal chips or anything else that will
damage your equipment.
2.1.6. The pump has a built-in check valve;
please do not install any other valve on
the suction.
2.1.7. ATTENTION: Using the controller
between 15 and 30m height, users may
adjust the starting pressure by the
screw placed in the top of the control.

2.1.9. For best performance use pipes at
least the same diameter as the pump's
inlet and delivery outlet openings. It is
recommended to use metal hose for outlet
piping.
2.1.10. Do not let your pump run when there
is no water available or water temperature
is over 40°C (104°F).

This mark located outside the
connection box is a warning for
an electrical hazard.
Before operation, please check if the
voltage is correct and be sure if the circuit
breaker and grounding connectors are all
connected in accordance with local
regulations.

3. Wiring diagram
WARNING:
Risk of Electric Shock - This pump is
supplied with a grounding conductor and
grounding-type attachment plug. To reduce
the risk of electric shock, be certain that it
is connected only to a properly grounded,
grounding-type receptacle".

4. Operation
Never run pump when no water is available.
When you have successfully installed the
pump and fill the chamber with water,
please follow the instructions on Fig. 2 to
start up the operation.
4.1.1. Remove the filling plug and fill the
chamber with water and then replace the
plug.
a. Remove the filling plug
b. Fill water in chamber
Water
c. Replace the filling plug
Fig. 2
4.1.2. When the pump inlet is lower than the
water supply level, please remove the
filling plug to let water back flow to the
chamber. It can be repeated as many
times as necessary till the air is
completely released from system. Then,
replace your filling plug.
4.1.3. For start up of the first operation or
after long time inactivity, please place a
screwdriver against the shaft at motor
end and turn clockwise to see if rotor
spins freely. (Fig. 3). If it is, you are free
to run the pump.
4.1.4. When the pump is running normally,
please measure the running current with
a wattmeter. If it exceeds the rated value
on nameplate, please check if your power
supply voltage is within ±10%. Please
contact your pump supplier if you are not
sure how to correct it.
2.1.11. For your safety, please hook up a
circuit breaker and connect grounding
connections to the pump in accordance
with local regulations.

5.2 Pump doesn't start:
a). Not enough water supply, the security
system has been activated and the LED
(FAILURE) is on --- check the water
supply and restart the pump through
the reset switch(RESET).
b). Pump is blocked: LED (FAILURE) is on
and the security system is activated.
When we act on the manual start switch
(RESET) the LED (ON) is activated but
the pump doesn't work --- consult your
dealer.
c). Failure in the electronic circuit --- switch
off power supply, wait a few seconds
and turn it on again. If the pump doesn't
start immediately then replace the
circuit.
d). No electrical supply --- check the proper
electric feeding. The tension LED
(POWER) should be on.
e). Not enough pump pressure --- the
security system has been activated and
the corresponding LED (FAILURE) is
on. Check that the pump pressure is
0.8kg/cm² higher than the starting
pressure of the controller.
f). Air in the pump aspiration --- the
pressure gauge will indicate a pressure
lower than the nominal or constant
oscillations.The security system will act
by stopping the pump and the LED
(FAILURE) will be on. Check the sealing
of the connections and O-ring of the
aspiration conduct.
5.3 The pump starts and stops repeatedly:
a). Small leakage in some point of the
installation --- verify possible tap of
tank leakages and repair them.
5.POSSIBLE PROBLEMS
5.1 Pump doesn't stop:
a). Water leakage higher than 1.2 l/min at
some point --- check the system,the
tap,etc.
b). Manual start switch (RESET) is blocked
--- press it for several times. Consult
your dealer if the problem persists.
c). Breakdown on the electronic board ---
proceed to its substitution
Fig. 3
4.2.1. Be sure that the pump is correctly
primed, and then gently open the tap.
4.2.2. Connect the controller to the electric
supply. The tension LED will light
(POWER)
4.2.3. The pump starts working automatically
and within a period of 20-25 seconds the
pressure gauge will reach approximately
the maximum pressure provided by the
pump.
During its working the corresponding LED
(ON) will be on.
4.2.4. If there is no discharge flow after a few
minutes, please turn off the pump and
repeat the Process of 4.2.1. Turn the
pump on and off several times until it is
working normally.
4.2.5. Close the tap indicated on point 1 After
7-9 seconds the pump will stop. The
tension LED (POWER) will be the only
one to remain on. Any problem after this
procedure will be due to defective pump
priming.

6. Troubleshooting
Problem
1. pump does not
start
2. Pump cuts out
during operation
3. Electric shock
4. Pump runs
normal but with
very low
discharge flow
Cause
a. No power supply
b. Too low/high voltage
c. Seized-up pump
a. Seized-up pump
b. Overloaded motor
c. Poor water supply
d. Overheating due to
excessive water
temperature
a.Ineffective grounding
a. Poor water supply
Remedy
Connect the electricity supply
Check if supply voltage is within ±10%
Place a screwdriver against the shaft end of
the motor to check it the rotor will spin
freely, and contact your pump supplier.
Same as above
Turn off the power supply and restart or
contact your pump supplier.
Check if pump suction inlet is blocked.
1. Wait till water temp. cool down before
restarting the pump.
2. For rapid restart, fill cold water to the
chamber to quickly cool down the liquid
temp.
Reactivate grounding.
check if water supply is adequate and if the
suction pipe is blocked.
7. Maintenance and service
Under normal operating conditions, the pump is maintenance free. It is especially critical,
when the ambient temperature reaches 40oC (104oF), to keep your pump site dry and
maintain good ventilation. It is always advisable to provide accessible space around the
pump.
You may refer to troubleshooting check list to find out a quick solution for your problems.
However if the problems are still existed after your attempts or you need other services,
please contact your pump supplier. Do not attempt to disassemble the pump as it will
void your warranty.
Before starting work on the pump, make sure that the electricity supply has been
switched off and that it cannot be accidentally switched on.
