2.0 SAFETY INSTRUCTIONS AND WARNINGS
Before installing your new aqua misting pump, please read the following instructions carefully to
avoid damages to the user, surroundings, and the pump system itself.
2.1 BEFORE OPERATING THE PUMP SYSTEM
Before operating the pump system, carefully inspect the shipment to locate possible missing parts or
damages. Please report anything, which is not satisfying, to the supplier of this system.
The plug on top of the high-pressure pump must be replaced with the enclosed oil dip stick.
Oil level must be checked.
The insulation on the wire must be flawless, and without cracks. In doubt, please contact the
supplier of this system.
Please see if the voltage displayed on the registration plate on the motor is equal to the voltage in
your power supply.
2.2 CURRENT CONNECTION
Wrong current connection of the pump system can lead to life threatening electrical chocks. The
pump system must only be connected to electrical circuits with earth leak circuit breaker.
2.3 SAFETY INSTRUCTIONS
This pump system can produce a high pressure. Wrong handling can lead to serious injuries.
For your own sake and safety of other persons please follow the rules listed below:
The pump system must not be operated if cable or safety devices are damaged.
The pump system may only be used for humidifying of air – it may not be used as a high-pressure
cleaner.
Water pressure from the pump system should never be pointed at people, animals etc.
2.4 SAFETY DEVICES ON THE PUMP SYSTEM
The high-pressure pump is on the pressure side equipped with a bypass valve. This valve leads the
water, which is not needed on the high-pressure site, back to the suction side of the filter. Do not
mount a ball valve or similar, which can shut off waterflow between the pump system and nozzles +
from the pump system and back to the filter section.
The pump unit will be over heated if more than 80 % (Capacity of the pump) is running in
circulation, which may cause breaking the pump, valves, nozzles etc. The temperature may not
exceed 50 °C.
2.5 MOTOR OVERLOAD PROTECTION
The motor is fitted with a motor protection relay which protects the motor against overload. At an
increased power consumption (error) the motor protection relay will automatically turn off the
power supply and the motor are switched off. Before rebooting the pump system at the red button
(inside the cabinet), the cause of failure must be found and repaired.
Be aware that the motor is not overheated if it has too many start/stops.
2.6 MOTOR CONNECTION TO POWER
All systems have CEE plug 400 Vac pre-installed. In case of pump service, the CEE plug must be
removed from socket to avoid any hazard.

AMP mounting and user manual, Pumps 2022-1 page 4 of 14
3.0 OPERATION DIRECTIONS
3.1 WATER CONNECTION
Water connection to the pump uses a regular water hose minimum 3/4” in diameter and minimum
1,5 bar pressure (The pump itself just need more than 0 bar). The water is lead into the pump
through low pressure filters. Flow direction is indicated by an arrow on the filter housing. Please
check the filters for impurities by routine. Filter house is delivered with a standard 5µm cartridge
filter inside.
3.2 START/STOP PROCEDURE
Start
Observe that the stop button on the electrical box is set to “OFF” to assure it is turned off.
Turn on the water supply and turn the power switch to “MAN”. Your system will now be filled with
water. Now the pump system is ready for manual or automatic operation.
Stop
Stop the pump system by turning the power switch to “OFF” and pump system will stop
immediately.
3.3 PRESSURE REGULATION
The pump has a pressure regulation. Factory settings are max. 70 bar. This basic adjustment must
not be changed. Pressure regulation is automatic with different numbers of nozzles.
3.4 FUNCTION
The pump system is provided with a manual and an automatic mode.
MAN:
Used when the pump system must run continuously (manual), such as soaking etc.
In the manual position, there is no security system for pressure, bleed-off etc.
OFF: Pump system is turned off.
AUTO:
Used when the pump system must run automatically (normal position). Can start the pump system
by external thermostat, timer, or other control systems. If the pump system does not reach operating
pressure within a given period of 20 sec., it will turn off. Before re-starting the pump system, the
cause of failure must be found. This function is controlled by a 25-bar pressure switch.
To restart – turn off the switch and return to “AUTO” mode again.
V-belt drive:
After few hours of operation, make a control, that the operation in total is OK including an extra
control, that the pulley is tensioned and in the right position.
Inside the belt house, you find an extra V-belt – for service if needed.

AMP mounting and user manual, Pumps 2022-1 page 5 of 14
4.0 MAINTENANCE
Your pump demands just a minimum of maintenance, however before operation the oil level must
be checked.
Pump routine maintenance:
After the first 50 hours: Oil change. (Oil type 15W-40).
Every 500 hours: Oil change (minimum each year).
Every 1000 hours: Replace the valves – Replace piston seal rings (or replace a service pump).
Bad seal rings, condense or cleaning with water can eventually lead to water in the oil.
In extreme conditions/use – Please check/replace oil etc. regularly.
If you have too much water leak, you can replace the entire pump unit with a service pump.
Filters:
The water filters must be checked and changed regularly. Minimum once a year.
Check pressure before and after the filter. If pressure loss exceeds 1 bar, the filter must be changed.
Pre-cleaning:
Before connecting the water supply hose and the high-pressure hose/pipe: Pipe system and
couplings should be cleaned for dust and sand (no particles inside pipes).
To empty the pump for water:
Disconnect the hose/pipe before and after the pump and demount filter house.
Start the pump system “MAN”. Let the motor run for approx. 30 sec. until the pump system is
totally empty for water.
Dry out fittings and other parts with e.g., high-pressure air to ensure all parts are completely dry.
The pump system should be mounted in a place free of frost and if not possible, you need to protect
the pump system with an anti-freeze fluid.
If the pump system by mistake is frozen, do NOT start. De-freeze pump system and accessories
before start-up.
NEVER START A FROZEN PUMP SYSTEM!
Pump for multiple sections service – pipeline with high pressure:
Before you make service on the decentralized solenoid valve or when the system is stopped over a
long period as the winter-season.
Make a pressure relief by opening the valve at the end of the pipeline or loosening a screw fitting on
the pipeline for taking of the high pressure.

Delivery and mounting the pump.
Delivery:
Demounting from transportation pallet:

AMP mounting and user manual, Pumps 2022-1 page 9 of 14
When ordering a universal pump with AMP 54.
When delivered the system is standard for 1 section:
 Bleed-off valve for eliminating the pressure when pump stop (No dripping from nozzles)
 Low pressure solenoid valve open 1 sec. before pump start (reduced vacuum at start)
Why change the pump to handle multiple sections:
 The system will be able to handle capacity down to 0,0 l/h with a temperature safety system.
 The pump and low-pressure solenoid valve operate simultaneously.
 A non-return valve ensures that water remains in the main pipeline and therefore provides a
better, faster, and more even misting
What you MUST change if you run for multiple sections:
Insert a short wire (jumper) into the terminal 23|24 and the program change to multiple sections
incl. temperature security system.
Insert the non-return valve straight after the pump and you have constant pressure inside the pipe
feeding line for multiple sections.

Frost protection of the pump and pipeline.
If the system should be shut down for the winter, make sure that it is frost protected. It is almost
impossible to drain all the water from the system, so instead, fill it with anti-freeze windshield
washer fluid (Min. approved for -21°C)
You will need about 1 liter of anti-frost fluid per 10 meters of pipe + a some extra for pumps, filters
etc.
AMP 48 remote wi-fi control for service, can with success be used for this job.
1. Empty the filter house and insert a new cartridge filter.
2. Arrange a tank with a higher level than inlet to the pump (It can be a pressure tank or a
separate low-pressure pump)
3. Put the ¾” low pressure hose down in the tank, ready for water to the pump (no air inside
the hose)
4. Make a manual start of the pump, be sure the pump works OK and makes the right pressure
without any disturbing sounds.
5. Open the end of the high-pressure pipe – one by one if more pipelines.
6. Start the pump and stop again when anti-freeze fluid comes out of the end of the pipeline.
Close the end of the pipeline and proceed to the next pipeline and redo the step – when all
pipelines are filled with anti-freeze fluid continue to the next step.
7. Ensure that the end of each pipeline is closed properly
8. Start the pump with normal pressure and let all the nozzles spray minimum 30 sec.
The system is now frost protected.
In the springtime or when you are sure to avoid freezing the system, make the same again, but this
time with normal water directly from the pipeline, instead of anti-frost fluid.
Check the pump and pipeline for errors. Change the oil in the pump (SAE 15/40) and the system is
now ready for a new season.
