2.4 Safety systems
Several safety systems have been conceived during the airless unit design and manufacture to
safeguard the operator, in compliance with pr EN 12621 Directive about paint.
SAFETY INFORMATION
In case of units that are to be used in areas with potentially explosive atmospheres, before starting
working the operators must disable the unit power supply, by putting it “out of order”. They also
must ensure that the unit cannot be restarted unintentionally.
All further necessary environmental safety measures must be adopted (such as the elimination of
gas or residual dusts, etc.).
SAFETY VALVE
A 8 bar calibrated safety valve is installed to ensure the pump working pressure does not exceed
the limits inside the feeding circuit.
If the calibration pressure is exceeded, the valve opens by releasing the excess of air.
WARNING
DO NOT REMOVE THE VALVE PLASTIC PROTECTION. ANY TAMPERING WITH COULD BE
DANGEROUS FOR THE OPERATOR AND COMPROMISE THE EQUIPMENT GOOD WORKING.
BALL VALVE
In case of anomalies during working, turn 90° the ball valve lever. In this way the air supply will
be interrupted and the residual pressure inside the pump will be released.

16
Safety Some pictograms can be found on the pump with the safety warnings to follow by anyone who is
pictograms going to use it.
WARNING
THE MANUFACTURING COMPANY IS NOT TO BE HELD RESPONSIBLE FOR DAMAGE OR
ACCIDENTS TO PEOPLE OR THINGS COMING FROM THE NON-COMPLIANCE WITH THE
PRESCRIBED RULES.THE RESPONSIBILITY RESTS ENTIRELY WITH THE OPERATOR HIM
SELF.
2.5 Workable products
All airless ANEST IWATA pumps are conceived to paint ferrous material in general, wood
and plastic.
Models ALS 333 C, ALS 433 C and ALS 453 C are intended for solvent-based paints with
a maximum viscosity of 85 sec/Ford #4 (100 sec/NK-2).
Models ALS 423 TX and ALS 433 TX are intended for high viscosity thixotropic water-based
paints.
To use the equipment with special products ask for the approval of the manufacturer.
Moreover, the technical features of the unit must be adapted for processing such products.
ANEST IWATA is not liable for any accident due to UNAUTHORISED and non qualified personnel
using the pump or personnel using it for purposes that are different from the above-mentioned
ones.
WARNING
DO NOT USE:
- ANY HALOGENATED HYDROCARBON SOLVENTS, SUCH AS TRICHLOROETHANE, METHY-
LENE CHLORIDE OR SOMETHING LIKE THAT;
- ANY TOXIC PRODUCTS SUCH AS PETROL, KEROSENE OR COMBUSTIBLE GASES;
- ANY HERBICIDE OR PESTICIDE
- ANY RADIOACTIVE FLUID

3.1 Operation description
Airless pumps are composed of two main parts: the pneumatic motor and the pumping unit.The
pneumatic motor is provided with an internal valve system for changing the movement direction.
The pumping unit is composed of an anti-wear chromium plated suction body (liner) and a rod.
The gaskets can be adjusted.
The motor straight and alternate movement produces an equivalent movement in the pumping unit.
A system of valves allows the simultaneous suction and pressurisation of the product to be spra
yed, in the two chambers of the suction body,therefore guaranteeing the utmost uniformity during
the application

4.1 Check on the purchased product
Before using the pump, make sure it has not been damaged during transport or storage.
Also check that all standard components are inside the packaging.
4.2 Conditions for installation
• The installer must know the ATEX classification of the installation area, as well as the risks coming
from a potentially explosive atmosphere, by paying attention to the explosion and fire risks so as to
adopt the most suitable protections.
• All maintenance, assembly and disassembly operations must be carried out by a qualified staff
out- side the area at risk of explosion.
• Also check that the accessories comply with the essential safety requirements of the ATEX direc-
tives. Handle them with great care to avoid changing their features.
• Once installed, clean the unit.
• Use antistatic hoses for connection of Airless Unit and spray gun.
The equipment must be installed by a specialized and authorized staff.
In any case, follow the instructions below.
Painting must preferably take place inside a suitable spray booth equipped with suction devi-
ce.
Do not use the unit if the suction device is off.
WARNING
IF PAINTING IS CARRIED OUT OUTSIDE THE SPRAY BOOTH, ALWAYS OPERATE IN A PLACE
WITH A RIGHT VENTILATION TO AVOID CONCENTRATING INFLAMMABLE VAPOURS COMING
FROM SOLVENTS OR PAINTS.
4.3 Installation
- Place the equipment on the floor, on a horizontal surface.
- Secure it firmly to the ground by means of the trolley fastening bracket (pic. 2 on page 19).
- Connect the suction pipe steadily (pos. A in pic. 2 on page 19) and the material recirculation pipe
(pos. B in pic. 2 on page 19).
- Connect the high pressure pipe for paint to the compensating filter.
- Earth the free end of the ground cable directly.
- Connect the airless gun to the other end of the air/paint twin pipe.
- Connect the air supply pipe to the installation.
WARNING
- CHECK THE PROPER TIGHTENING OF ALL FITTINGS, SINCE THEIR SUDDEN OPENING CAN
SERIOUSLY INJURE PEOPLE.
WARNING
- CONSULT THE LOCAL CODE FOR DETAILED INSTRUCTIONS RELATIVE TO GROUND CON-
NECTIONS IN THE WORK AREA AND TO THE TYPE OF SYSTEM USED.
- THE GROUND CABLE (INCLUDED IN THE SUPPLY) MUST HAVE A MINIMUM SECTION
EQUAL TO 1.5 mm2.
- ONE END OF THE CABLE MUST BE EARTHEN WHILE THE OTHER MUST BE CONNECTED
TO THE LID OF THE PNEUMATIC MOTOR SILENCER.

4.4 Cautions
1. Operate the pump with air filtered by means of an air filter with a filtering section smaller than
50 µm; we recommend using a filter with condensate automatic discharge.
2. Do not run the pump idle.
3. Do not spray paint or solvents towards the pump.
4. Do not place the pump close to heat sources or exposed to the sun. Locate it in a place shel-
tered from water sprinkles.

5.1 Use
This section describes the airless unit use in compliance with the safety standards in force.
Read this section carefully.
LIMITS AND CONDITIONS OF USE
Any modification to the constructive shape or to the assembling position is allowed only after
asking for ANEST IWATA EUROPE technical service authorization.
If there is no authorization the ATEX approval in no longer valid.
Environmental conditions
Room temperature: min. + 5°C; max. +40°C
The plate data of the maximum superficial temperatures refer to measures taken in normal environ-
mental conditions and to a normal installation.
Any minimum variation of these conditions can greatly affect the heat development.
5.2 Safety rules during use
