SAFETY WARNINGS
EE
Fire and explosion
Solvents and coating materials can
be highly flammable or combustible
when sprayed. ALWAYS
material suppliers instructions and COSHH
sheets before using this equipment
Users must comply with all local
and national codes of practice and
insurance company requirements
governing ventilation, fire
precautions, operation and house-keeping of
working areas
FOR KB-522 ONLY:
Do not use Solvents or coating
materials containing
HALOGENATED HYDROCARBONS with this
equipment.
FOR KB-522-SS ONLY:
This equipment, as supplied, is suitable for
use with Halogenated Hydrocarbons and the
user must ensure that all other equipment in
the system is also suitable for use with these
materials. DO NOT SPRAY MATERIALS
CONTAINING THESE SOLVENTS EXCEPT
WITH EQUIPMENT SPECIFICALLY
DESIGNATED BY THE MANUFACTURER
AS BEING SUITABLE FOR SUCH USE.
Static Electricity can be generated
by fluid and/or air passing through
hoses, by the spraying process
and by cleaning non- conductive
parts with cloths. To prevent ignition sources
from static discharges, earth continuity must
be maintained to the spraygun and other
metallic equipment used. It is essential to use
conductive air and/or fluid hoses.
refer to the coating
Personal Protective
Equipment
Toxic vapours – When sprayed,
certain materials may be
poisonous, create irritation or be
otherwise harmful to health.
Always read all labels and safety
data sheets for the material before
spraying and follow any recommendations. If
In Doubt, Contact Your Material Supplier
The use of respiratory protective
equipment is recommended at all
times. The type of equipment must be
compatible with the material being sprayed.
Always wear eye protection when
spraying or cleaning the spraygun
Gloves must be worn when spraying
or cleaning the equipment
Training
Personnel should be given adequate training
in the safe use of spraying equipment.
Misuse
Never aim a spraygun at any part of the
body. Never exceed the max. recommended
safe working pressure for the equipment.
The fitting of non-recommended or non-
original spares may create hazards.
Before cleaning or maintenance, all
pressure must be isolated and relieved from
the equipment.
Never exceed the recommended safe
working pressures for any of the equipment
used.
Never drill into or modify the pressure feed
cup in any way.
Do not adjust, remove or tamper with the
safety valve. If a replacement is necessary,
only use DeVilbiss supplied spare Valves.
The materials used in the construction of the
cup are (bearing in mind the warning on
Halogenated Hydrocarbons) solvent
resistant enabling the cup to be cleaned
using gun washing machines. However, the
lid assembly must not be cleaned in a gun
washing machine as it contains parts that
will be damaged.

Installation
IMPORTANT: To ensure that this equipment
reaches you in first class condition, protective
coatings, rust inhibitors, etc., have been used.
Flush all equipment through with a suitable
solvent before use to remove these agents from
the material passages.
Operation
CAUTION: The cup is under pressure.
Disconnect the air supply and release the
pressure in the cup assembly before removing
the cup from the lid assembly or disconnecting
the gun or the material hose. Never allow the cup
to lay on its side or fall over when it contains
material.
Controls (See Figure 1)
Safety Valve (14): The safety valve limits the
maximum air pressure to the cup. If the
safety valve does not work properly, over
pressurisation may occur and cause the cup
to rupture or explode. Occasionally pull the
ring on the safety valve and make sure that it
operates freely. If the valve is stuck or does
not operate smoothly it must be replaced
with a valve having the same rating. Never
attempt to adjust or dismantle the safety
valve.
Regulator (15): Controls the pressure of the
coating material in the cup. To increase the
1. Connect the coating material hose (Fig 2, A)
from the cup outlet to the gun.
2. Connect the air hose (B) from the cup outlet
to the gun.
3. Connect the air supply hose (C) to a filtered/
regulated air supply and to the cup inlet.
pressure, pull knob out, turn the knob in the
direction of the arrow shown on the knob, to
reduce pressure turn in the opposite direction.
When pressure is set push knob in to lock.
Pressure Relief Valve (6): Vents the air
pressure in the cup. To open, turn valve
counter-clockwise. CAUTION Do not
unscrew the pressure relief valve (6)
completely when relieving the pressure as it
may have sufficient air pressure to eject the
valve from the lid creating a hazard.
Pressure Gauge (8): Indicates the air
pressure in the cup. Do not attempt to
remove the cup (15), spray gun or coating
material hose if the gauge indicates pressure
in the cup.
NOTE: Regularly check that the pressure gauge
is reading correctly.
1. Mix, prepare and filter the coating material to
be sprayed according to the manufacturer’s
instructions.

2. Adjust the spray gun controls as described in
the Operation Manual supplied with the gun.
3. Turn the regulator knob (15) to the minimum
pressure and open the pressure relief valve
(6) to vent any pressure in the cup.
4. Remove cup (11) by turning ring (1) counterclockwise and fill with the coating material,
DO NOT OVERFILL. (If using the liner Kit KK
-5051, see section on liner fitting)
5. Replace lid assembly on cup, push down
with the handle and tighten ring (1).
6. Close the pressure relief valve (6), turn on
Preventative Maintenance
CLEANING
DO NOT clean the cup lid assembly in a gun
washing machine as the safety valve (18), gauge
(6) and regulator (19) contain parts that will be
damaged.
1. Disconnect the air supply and relieve the
pressure in the cup.
2. Remove the cup (11) and empty surplus
coating material. Wipe the lid and the inside
of the cup clean.
3. Fill the cup with a small quantity of compatible solvent and refit. Connect the air supply,
and adjust the supply air pressure to 3.5 bar
(50 lbf/in2).
7. Adjust the material pressure to 0.7 bar (10
lbf/in2).
8. Test spray, adjust atomisation and material
pressures to suit required application rate.
NOTE: To reduce the material pressure turn
regulator (15) down and open the pressure relief
valve (6). Close relief valve (6), and readjust the
regulator (15).
spray the solvent until clean.
4. Disconnect the air supply and relieve the
pressure in the cup.
5. Remove the cup (11), empty the residual
solvent and dry internal surfaces.
6. Inspect that the check valve (12) and pressure relief vent holes in the lid are free from
coating material.
NOTE: The check valve cap may be unscrewed
to aid inspection and cleaning, DO NOT dismantle any further.
