Erp EEI0.23 High Energy efficient circulator pump Installation Guide
Warning
Prior to installation, read these installation and operating instruction.
Installation and operation must comply with local regulations and accepted
codes of practice.
General information
These Operating Instructions explain the functions and operation of the pump when installed and ready for use. The figures referred to in the text can be found on the fold-out pate at the front
Low-energy circulation pump
Low-energy circulation pump is designed for the circulation of water in heating systems. Install the low-energy circulation pumps in
- Underfloor heating systems
- One-pipe systems
- Two-pipe systems
Low-energy circulation pump incorporates a permanent-magnet motor and difference-pressure control enabling continuous adjustment of the pump performance to the actual requirements.
Advantages of installing a Low-energy circulation pump
The installation of a Low-energy circulation pump means
Easy installation and start-up
-
Low-energy circulation pumps is easy to install. With the factory setting, the pump can, in most cases , be started Without marking any setting
High degree of comfort -
Minimum noise from valves, etc.
Low energy consumption -
Low energy consumption compared to the convention circulation pumps
It is A-labelled as follows:
Pump liquid
Clean, thin, non-aggressive and non-explosive liquids, not containing solid
particles, fibres or mineral oil.
In heating systems, the water meet the requirements of accepted standards on
water quality in heating system

(The button is used for change the pumps modes, for example: from Constant
pressure to proportional pressure, or toECO mode, also can for Air-venting
mode. )

| Light for each speeds
(The 6 lights are shown the different working conditions. Only under two
modes(Constant Pressure and Proportional Pressure, these lights can be
chosen.)
8| | Button for setting
(This button is used for setting the different speeds(light in 1,2,
3,4,5,6) for two modes. Using this button, we can chose the speeds from
Max.to MM.. )
Lights fields indicating the pumps setting
Low-energy circulation pump has seven optional setting which can be selected with the push-button. See 8 in the above label The pump setting is indicated by seven different light fields. See the above label.
Push-button for selection of pump setting
Every time the push-button is pressed , the pump setting is changed. A cycle is seven button presses.

Descripition
---|---
CP2,CP3,CP4,CP5| The Operating Point moves back and forth on the curve
according to the volume of flow from the system.As shown in the graph,the pump
pressure remains constant, not affected by the volume demands of flow.
CP1–Min. Speed
CP6–Max.Speed| f he two speeds arc the min. and Max. ones under
constant Pressure, the curve shown as in graph. can not keep constant. I t
rises and goes down as Manual operation.
PP2,PP3,PP4,PP5| The Operating Point moves back and forth on the
Proportional Pressure curve according to the volume of flow from system. As
shown in the graph. the pump pressure is directly proportional to the flow
demands.
CP1–M i n . Speed
CP6- -M ax. Speed| The two speeds are the min. and Max. ones under
Proportional Pressure,thc curve shown as in graph. can not keep constant. It
rises and goes down as Manual operation.
ECO| this mode use working as “autoadaptation”. It confines the
performance of the pumps in aimed scope. As shown in Graph.:
- Performance can be adjusted according to the scale of system
- Performance can be adjusted according to the changing of load during a specific period. Under the mode of ECO”, the pump is controlled by means of Proportional pressure.
Fault in finding chart
Warning
Before starting any work on the pump, make sure that the Electricity supply
has been switched off and that it cannot be Accidentally switched on.
Installation
Warning
The pump liquid may be scalding hot and under the high pressure. Drain the
system or closed isolated valves on either side of pump before removed the
screws.

Remedy
---|---|---|---
the pump does not run| light off| a) One fuse in the installation is blown|
Replace the fuse
| b) The current-operated or voltage-operated circuit breaker has tripped
out| Cut in the circuit break
| c) The pump is defective.| Replace the pump.
