Dear Customer,
You are the owner of our new SAMES KREMLIN pressure regulator and we would like to take this
opportunity to thank you.
To make sure your investment will provide full satisfaction, special care has been taken by SAMES
KREMLIN during all designing and manufacturing processes.
To obtain the best result, safe and efficient operation of your equipment, we advice you to read and
make yourself familiar with this instruction and service manual. Indeed, the non-compliance with
instructions and precautions stated in this manual could reduce the equipment working life, result in
operating trouble and create unsafe conditions.
1. GENERAL SAFETY INSTRUCTIONS
WARNING : Any misuse of the equipment or accessories can damage them, result in serious
body injury, fire or explosion hazard and reduce the equipment working life. Read,
understand and comply with the safety instructions hereafter.
The personnel involved in operating and servicing this equipment must be aware of all safety
requirements stated in this manual. The workshop supervisor must be certain that the personnel has
perfectly understood the safety instructions and complies with them.
Read all instruction manuals as well as the tags of the equipments before operating the equipment.
Refer to local safety instructions and comply with them.
INSTALLATION REQUIREMENTS
Ground the equipments.
Use the equipment only in a well-ventilated area to prevent from serious body injuries, fire and
explosion hazards. Do not smoke in the spray area.
Never stock paints and solvents in the spray area. Always close the pots and the tins.
Always keep the spray area clean and free from debris (solvent, rags,…).
Read paint and solvent manufacturer's technical instructions.
Spraying of some materials may result in hazardous working conditions. To protect the operator,
respirator mask, hand cream, glasses and hearing protective earplug are required (Refer to chapter "
Safety equipment" of SAMES KREMLIN selection guide).
EQUIPMENT REQUIREMENTS
The operating pressure of these equipments are particularly high. Consequently, some precautions
must be taken in order to prevent from accidents and from unsafe working conditions.
Never exceed the components maximum pressure of the equipment.
HOSES
Do not use hoses with a maximum burst-proof pressure less than four times the maximum service
pressure of the pump (see data sheet).
Be certain the hoses are not crimped, leaking and not unrolled.
Be certain hoses are in good conditions and showing no evidence of damage.
Use only air hose with static conductor to connect the pump with the spray gun.
All fittings must be tight and in good condition.
PUMP
Ground the equipment (use the connection on the pump).
Do not use any product or solvent incompatible with the pump components.
Use the appropriate solvent for the material being sprayed to increase the equipment working life.

SAMES KREMLIN Page 3 Manual : 573.008.212
GUN
Never wipe the end of the tip with the fingers.
Always depressurize air and hoses before carrying out any servicing on the gun.
Never point the spray gun at anyone or at any part of the body.
PRESSURE REGULATOR
Assemble conductive hoses upstream and downstream of the regulator.
MAINTENANCE REQUIREMENTS
Guards (air motor cover, coupling shields, housings …) have been designed for
safe use of the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or
damage to property due to removal or partial removal of the guards.
Never modify these equipments.
Check them daily, keep them in a good condition and replace the worn parts only with SAMES
KREMLIN parts.
Before cleaning or removing components of the equipment, it is compulsory :
- to stop the pump by shutting off the compressed air supply,
- to open the pump drain valve,
- to press the gun trigger to depressurize the hoses.
2. DESCRIPTION
The pressure regulator enables to adjust the fluid pressure into the circuits of low and medium pressure.
The pressure regulator is mounted on the fluid circuit between the pump fluid outlet and the gun fluid inlet.
It enables to refine the pressure of the gun. It exits a spring operated model and an air operated model.
The back pressure regulator is mounted on the back fluid circuit. It enables to regulate a constant
pressure and to ensure at the same time a fluid circulation into the hoses.

The 1 m / 39.37" distance indicated in these diagrams is given for information
purposes only and hold harmless to SAMES KREMLIN. The user is responsible for the
extraction and conditioning of the painting area where the equipment is used, for
working conditions conditions (refer to EN 60079-10 standard). The 1 m / 39.37"
distance may be modified if trials carried out by the user deem this necessary.
(Nota : diagrams represented with Airmix® regulators)
NOTA :
To ensure a larger lifetime of your equipment and to obtain the best flow
rate possible, you must mount the regulator in vertical position.
5. START UP
Start up the pump (Refer to pump instruction manual).
Tighten the screw located on the upper part of the spring operated regulator or turn the regulator of the air
operated assembly.
Start up the gun (Refer to gun instruction manual).
Adjust the fluid regulator to obtain the required pressure and fluid flow.
Nota : Refer to the regulator features to comply with the inlet and outlet pressures (refer to the
enclosed document).
6. MAINTENANCE
Keep the pressure regulator clean to ensure its proper working.
When flushing the pump, make the solvent circulate in circuit to clean all the elements (pump, hoses,
regulator, gun).
