• The product is most applicable to the following systems:
  stable and variable-flow heat supply system variable-temperature pipeline heat supply system

• heat supply system with night mode

• HVAC system Industrial circulation system domestic heating and domestic water supply system

This pump is equipped with permanent magnet motor and differential pressure controller, capable of automatically & continuously adjusting motor performance to meet the actual needs of the system. This pump is equipped with control panel on the front for easy operation by users.

Advantages
Easy installation and start-up

Provided with self adaptive mode
AUTO

Initial setting). In most cases, the motor pump needs no adjustment  and can be readily started and will
adjust automatically to meet the actual needs of the systems.

High-degree comfort

• Low operational noise of motor pump and whole system.

Operating Conditions

Ambient Temperature

Ambient temperature: 0 40

Relative humidity(RH):

Max. humidity: 95%

Medium (liquid delivery) temperature
Liquid delivery temperature: +2℃~110

To avoid condensation in control box and the stator, the temperature of liquid pumped by the motor pump must be always higher than ambient temperature.

System Pressure

Maximum pressure 1.0MPa(10bar).

Degree of Protection

IP 44

Inlet Pressure

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 the pump must definitely not be used to pump inflammable liquid such as rapeseed oil and gasoline. If the pump is used in a place with relatively high viscosity, the pump has lower performance. So when choosing a pump, the viscosity of liquid must be taken into account.

Installation

• When installing APUMP-HE series circulation pump, the arrow on the motor pump case indicates the flow direction of liquid through the pump.
• When installing the motor pump in the pipeline, the two gaskets supplied must be installed at the inlet and outlet.
• During the installation, the motor pump shaft must be horizontal.
  

Position of Junction Box

Changing Position of Junction Box

The junction box can be rotated in a step of 90°.
The procedures for changing the position of junction box are as follows:

1. Close the valves at the inlet and outlet and release the pressure;
2. Unscrew and remove the four socket head screws that fasten the pump body;
3. Rotate the motor to the required position and align the four screw holes;
4. Install the four socket head screws again and fasten them clockwise making sure they are fully tightened;
5. Open the valves at the inlet and outlet.
   

Warning
Pumping liquid may be high-temperature and high-pressure; therefore, the liquid in the system must be completely drained or the valves on both sides of motor pump must be closed before removing the socket head screws.

Thermal Insulation of Motor Pump Body

Limiting the heat loss of motor pump body and pipeline.
Motor pump body and pipeline should be thermally insulated to reduce their heat loss.
Do not insulate or cover the junction box and control panel.

Electrical Connection

Electrical connection and protection shall comply with local codes and norms.

Warning
The motor pump must be earthed
The motor pump must be connected to an external power switch, with 3mm minimum contact gap in both poles.

• APUMP-HE series circulation motor pump needs no protection from external motor.
• Check if the supply voltage and frequency are the same as parameters indicated on the nameplate of the motor pump.
• Connect the motor pump and power supply with the plug supplied together with the pump.
• After the power is supplied, the indicator lamp on the control panel is ON.

Button for selecting motor pump settings
By pressing the button once at 2 seconds interval, the motor pump setting mode will change to the next in sequence.
A cycle is constituted of every three presses on the button. For details, please refer to Section 6.2.

Motor Pump Setting

Motor Pump Setting Based on System Type
Initial setting=AUTO (Self-adaptive mode Recommended and available pump setting

• AUTO (Self Adaptive Mode) mode can adjust the performance of motor pump based on the actual heat demand of the system. Self adaptive mode adjusts over time to find the most effective setting, so before changing the motor pump setting, maintain
  AUTO (Self Adaptive Mode) mode setting for at least one week.

• If you select to change back to AUTO (Self Adaptive Mode) mode, the APUMP-HE motor pump can memorize its last setting in AUTO mode and continue adjusting the performance automatically.

• It may take several minutes or even hours to reach the optimal operation mode after motor pump setting is changed from the optimal setting (the “Recommended above mention”) to one of the other optional setting. If the optimal setting of motor pump fails to enable each room to obtain desired heat distribution, then you should change the motor pump setting to other settings.

• Please refer to Section 8.1 for the relations between pump setting and performance curve

Motor Pump Setting and Performance

AUTO

(Initial Setting)

| Highest to Lowest Proportional Pressure Curve| AUTO function will automatically control the pump performance within the specified scope. adjust pump performance based on system scale; adjust pump performance based on load variance within a period of time; Under the AUTO mode, the pump will be set to proportional pressure control;
Max| Velocity Max| It runs on the constant curve in a constant velocity. In the Velocity Max mode, the pump is set to work on the highest curve under all working conditions.
Min| Velocity Min| It runs on the constant curve in a constant velocity. In the Velocity Min mode, the pump is set to work on the lowest curve under all working conditions.

Performance Curve

Guide on Performance Curve
Every setting of the motor pump has corresponding performance curve (Q/H curve).
However AUTO (Self Adaptive Mode) mode covers just one performance scope.
The input power curve (P1 curve) belongs to every Q/H curve. Power curve represents the power consumption of motor pump in given Q/H curve with Watt as the unit. P1 value corresponds to the readings taken from the monitor of motor pump.

Curve conditions

The followings are applicable to the performance curve specified in the APUMP- HE series manual:

• Test liquid: air-free water
• Applicable density of curve ρ=983.2 kg/m³, and liquid temperature +60C
• All curves represent averaged value, and shall not be used as guarantee curve. If a specific performance is needed, then separate measuring shall be conducted.
• Velocity Max, Min curves have all been marked.
• The applicable Kinetic viscosity of the curve υ=0.474 mm²/s(0.474CcST)
