3.7 Pumping liquid
The pumping liquid includes thin, clean, non-corrosive and non-explosive
liquid which shall not contain any solid particles, fiber or mineral oil, and motor
pump must definitely not be used to pump inflammable liquid such as rapeseed oil
and gasoline. If the motor pump is used in a place with relatively high viscosity, the
motor pump has lower performance. So when choosing a motor pump, the
viscosity of liquid must be taken into account.
4.1 Installation
·

·
When installing microcirculation series energy-saving pipe canned motor pump, the
arrow on motor pump casing indicates the flow direction of liquid through the pump.
When installing the motor pump in the pipeline, two gaskets must be installed at the inlet
and outlet.
During the installation, the shaft of motor pump must be horizontal.

7.Control of Motor Pump
7.1 The constant speed running mode
Motor pump runs in the constant speed when it is in constant speed running
mode. Green light 1 as well as light 4 which is showing current power, will be
always on while the light 7 will also be on.
7.2 The auto operation mode
Motor pump will automatically exert necessary adjustment according to
current systematic performance when it is in the auto operation mode. Green
light 2 as well as light 4 which is showing current power, will be always on
while the light 7 will also be on.
7.3 Temperature control mode
Temperature sensor will obtain the feedback in terms of fluid temperature
and make a judgment on whether start or stop when it is in the indicating
temperature control mode. In such mode, the motor pump will stop when
temperature is over 50 centigrade, but it will run in constant speed when
temperature is below 36 centigrade. Green light 3, as well as light 4 which is
showing current power, will be on while the light 7 will also be on.
7.4 Timing mode
Motor pump will run in constant speed within time set by time controller when
it is in timing mode. The light 4 indicates the current time by showing the
hour and minute alternately. When it comes to the hour, light 5 will be on
while light 6 is on in the case of showing the minute. User can set and inquire
the start and end time point for 3 periods about the running of pumps. And
time points for 3 period are unnecessary to be reset when the power is off
due to the controller can keep a record of running parameters set by users
automatically.
7.5 Flushing function
When pumps are in the mode of standby for 8 hours, pumps will restart
automatically and then flush the pipe for 15 minutes. At the moment, it runs
in the constant speed mode. The flushing function is effective when it is in
either Temperature control mode or Timing mode. Under the circumstance,
the light 7 is on as well as light 4 is shining and the current running power is
presented.

7.6 Key pressing specification
The factory setting for pumps is that it is in the constant speed running mode.
When the power is on, Slightly pressing on “8 can help you switch
between different running modes.( it can be switched among the constant
speed running mode, the auto operation mode, temperature control mode
and timing mode.)
·Illustration for the timing mode setting
The light 4 will show the current time when it is in the timing mode. Hour and
minute are presented alternately.
The first step: Entering the timing mode( only in the timing mode the
setting of the timing mode is available.):
Pressing “8 ”and “9 ”for for 3s then setting mode is activated. In
the mode, light 4 is flashing and 88 positions shows the time period.(F0-F6)
The second step: settings for the current time and timing time:
When it comes to the setting mode,”88” can be switched from F0 to F6:
F0-F6 represents 7 time periods and their significance are presented below
F0 settings on current time
F1 settings on the start time of the first period
F2 settings on the end time of the first period
F3 settings on the start time of the second period
F4 settings on the end time of the second period
F5 settings on the start time of the third period
F6 settings on the end time of the third period
After firstly pressing “9 ” for 3s,Setting on hours is available (light 5 is
flashing) and now the current hour is shown. When pressing“9 ”,one hour
has been cut while pressing “8 ”vice versa.
If it is set then please socondly long press the “9 ”for 3s,Setting on minute
is available ( light 5 is flashing). When pressing “9 ”,one minute has been
cut while pressing “8 ”vice versa.
After thirdly long pressing “9 ”for 3s
Settings on the next time period is available ( For instance if F0 has been set
currently, then next step is for F1) and others are the same.
The third step: Quit the setting mode：
When any state from F0 to F6 is shown on the 88 position,and after long
pressing “8 and “9 ” for 3s, user can quit the setting mode;Now the time
is shown normally ( light 4 shows current time)
Range for time setting is 24 hours and all hour figure can be set from 0 to 23
as well as minute figure set from 0 to 59. Once finishing the setting and quit
the corresponding mode, the hour and minute shows alternately;
For example: when showing 8 in terms of 8:30 AM, the light 5 is on and when it
comes to 30 the light 6 is on.in addition, when showing 13 in terms of 1:25 PM,
the light 5 is on and light 6 is on when it comes to showing the 25. It will take
2s for switching time and showing alternately.

If users don't need 3 time period timing function and only one of them is
needed, the other two time periods are not necessary to be set in terms of
factory settings.( both of them can also be set as some same time).
If users only need one time period ,which is from 17:30 to 21:30 ,to be set and
runnning of pumps is not required at other time period, then we can make
some adjustments as following:
Time period Hour Minute
F1 17 30
F2 21 30
F3 0 0
F4 0 0
F5 0 0
F6 0 0
The time for factory setting is defaultly set as 0 and it can be modified as any
other identical values ,but it must make sure the rest of time periods shares
the same.
·Illustration for inquire on the time in timing mode:
In the timing mode:
After firstly long pressing the “8 ”for 3s,
Now the inquiry function for setting time is activated and it shows the current
time(F0). The figures for the hour and minute set by users are both showing
alternately and at the same moment LED light is flashing. Then short press
“8 ”and F1 mode is available. It plays the same rules for others and such
kind of function can help users to check the accuracy of time.
After long press “8 ” for 3s,Then quit the inquiry mode.
7.7 Indication lamp area of power consumption of motor pump
