10  TECHNICAL SPECIFICATION

ADEY reserve the right to amend the specification without notice .

10 .11 

Noise:  The equivalent continuous A-weighted sound pressure level at a  

 

 

distance of 1 metre from the pump does not exceed 70 dB(A) .

11  TROUBLE SHOOTING GUIDE

Symptoms

Error Code

Probable Cause

Recommended Action

No power

Blank screen

No power to APU

Internal re-settable 

fuse tripped

Check power supply/fuse

Disconnect APU from mains power for 20 seconds & and then re-connect

Pump(s) not 

starting

No power to APU

Ensure the green light is on the front of the APU, check fuse .

Low water

Low water in tank

Depress float valve to varify water is filling tank, check water level and 

supply .

System pressure = 

set pressure

APU functioning correctly . Check the set system pressure .

Pump run fail

Pump seized

Force the pumps to run using the pump test function . Clear error .

Pump run fail

System pressure set 

too high

System set pressure is set higher than the pump performance capability, 

reduce set pressure . Ensure you have purchased the correct APU for the 

system pressure required .

Sensor error

Pressure sensor fault

Remove pressure from the APU outlet and verify the displayed pressure 

is 0 bar . Error will be displayed if the sensor signal is outside parameters . 

(Replace sensor – call ADEY Customer Services) .

Pump(s) will not 

stop

Sensor error

System pressure set 

too high

System set pressure is set higher than the pump performance capability, 

reduce set pressure . Ensure you have purchased the correct APU for the 

system pressure required .

Pressure sensor fault

Remove pressure from the APU outlet and verify the displayed pressure 

is 0 bar . Error will be displayed if the sensor signal is outside parameters . 

(Replace sensor – call ADEY Customer Services) .

Low pressure alarm 

triggered

Low pressure

Leak in system .

Check system for leaks . Check pump activity in logs . Check for leaking 

pressure relief valve .

Low pressure alarm 

set too high .

Reduce Low press alarm pressure . Check system pressure range during 

normal operation .

Sensor error

Pressure sensor fault

Remove pressure from the APU outlet and verify the displayed pressure 

is 0 bar . Error will be displayed if the sensor signal is outside parameters . 

(Replace sensor – call ADEY Customer Services) .

High pressure 

alarm triggered

High pressure

System pressure 

too high

Check system operation . Increase High presure alarm set pressure .

Sensor error

Pressure sensor fault

Remove pressure from the APU outlet and verify the displayed pressure 

is 0 bar . Error will be displayed if the sensor signal is outside parameters . 

(Replace sensor – call ADEY Customer Services) .

Pump run time 

alarm activated . 

Pump running for 

longer than set 

time

Pump run time 

alarm

Pump filling system

Activate system fill option to suppress alarm for 24 hours .

Leak in system

Check system for leakage . Monitor using system fill volume log, reset if 

needed .

Increase pump run time limit .

Activity high alarm 

activated . Pump 

starting more than 

set value

Activity High 

alarm

Pump filling system

Activate system fill option to suppress alarm for 24 hours .

Leak in system

Check system for leakage . Monitor using system fill volume log, reset if 

needed .

Activity High alarm 

number too low

Increase the Activity High alarm value .

Sensor failure error Sensor error

Pressure sensor 

outside specifcation

Remove pressure from the APU outlet and varify the displayed pressure 

is 0 bar . Error will be displayed if the sensor signal is outside parameters . 

(Replace sensor – call ADEY Customer Services) .

Low water error

Low water

Loss of water supply 

to APU

Depress float valve to verify water is filling tank and check water level and 

supply .

Water level set 

too low

Adjust water level by turning float, ensure upper level probe is in contact 

with water when the fill valve is turned off .

Check water level prior to leaving unattended .

Water overflowing 

warning pipe or 

weir

Water level too high

Check function of the fill valve, replace or adjust if needed .

Pump NRV leaking

Isolate APU from system and mains water and replace non-return valve 

and holder .
