INTRODUCTION

The Earlex HV7000 “Spray Port” is an industrially rated, portable, paint spraying system and is intended for
use by professionals. HVLP stands for High Volume, Low Pressure. This is a type of spraying that allows you
to spray extremely accurately but without all the overspray that occurs with high pressure tank equipment. In
some parts of the world the high pressure systems are banned by law on environmental grounds and HVLP
type systems are the only alternative for professional type spraying. This system is extremely easy to use, very
safe and reduces the amount of paint used.

The Earlex Spray Port (model no. HV7000UK110PD, HV7000UK110H, HV7000UK230PD & HV7000UK230H)
is a portable system that is made up as a trolley unit that can be broken down into two separate parts, the main
Turbine Unit and the Carrier Stand. These two parts connect together via two quick release clips allowing the
complete system to be wheeled from a vehicle to the workplace or around the workshop. They are easily
separated so they can be stored in the back of a van or truck. The Carrier Stand holds the Air Hose and spray
applicator and also has space for a cleaning kit. The Earlex Spray Port (model no.HV7000UK110NF &
HV7000UK230NF) is supplied with the main turbine unit, hose and gun. Your Spray Port can be supplied with
a plastic spray applicator Type P or, an aluminium spray applicator Type A. Both types will give identical
excellent results.

PLEASE NOTE: We have done all we can to ensure that used correctly and according to these instructions,
this spray applicator will give long and trouble free life. We accept no responsibility for damage caused by the
use of incorrect or unsuitable substances, paints or fluids which have not been thinned correctly or are
unsuitable for the surfaces to which they are applied, health hazards arising from lack of ventilation when
working in confined spaces or failure of the equipment due to inadequate cleaning of the components after use.
If in doubt, always test a small inconspicuous area first. Always read the paint manufacturer’s instructions first.
Neither our guarantee nor the above statement affects your statutory rights.

IMPORTANT BASIC INFORMATION

SELECTING PAINT

This is a highly versatile spray kit that can be used with several different spray mediums including varnishes,
wood preservatives, enamels, oil and water based paints and cellulose. However some materials cannot be
sprayed so please check the recommendation of the manufacturer before buying the paint. If a material refers
to brush application only then it usually cannot be sprayed.

THIS UNIT SHOULD NOT BE USED FOR TEXTURED PAINTS. THESE MATERIALS CONTAIN PARTICLES
OF GRIT THAT WILL CAUSE PREMATURE AND EXCESSIVE WEAR. USE OF SUCH MATERIALS WILL
INVALIDATE THE GUARANTEE. TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY KIT PLEASE
READ THE INSTRUCTIONS CAREFULLY BEFORE USE.

SURFACE PREPARATION

Preparation of the surface and thinning of the paint are the two most important areas to be concerned with to
obtain the best results from your spray kit. Ensure all surfaces are free from dust, dirt, rust and grease. If
necessary smooth with sandpaper, or similar. Masking of areas is important to ensure you do not spray those
areas you wish to remain untouched.

THINNING

Your spray kit is supplied with a viscosity cup. Viscosity is a technical term used to indicate if a product is very
thin or very thick. If thin, the viscosity is said to be low, while if very thick the viscosity is said to be high.
Viscosity is measured in seconds. In order to spray some materials they need to be “thinned” (diluted).
Thinning is very important when spraying. Most paints are supplied ready for brush application and may need
to be thinned (diluted) for spraying purposes.
Follow the manufacturers guide for thinning in conjunction with a spray applicator. If in doubt please contact
the manufacturers of the paint. The viscosity cup supplied will help you determine the correct thickness of the
paint. Paint is “thinned” by adding the substance which the paint is based upon. If a water based paint then
water is added, if oil based then white spirit, if automotive coating then an automotive coating thinner is added.
As some paints, wood preservatives and other sprayable materials contain particles that have differing
qualities, please ensure that when filling the paint container of the spray applicator, that the paint is filtered
through either a funnel with a filter on it or through nylon tights or stockings. This will ensure that no large
particles enter the paint container, so preventing blockages and providing you with trouble free spraying.
Ensure that a face mask, gloves and goggles are worn at all times when spraying.

IDEAL VISCOSITY

Water based paints and 25 - 75 seconds
emulsions
Oil based paints 45 - 50 seconds
Wood preservatives No dilution
Primers 45 - 50 seconds

This spray applicator can be used with products having a viscosity ranging from 25 to in
excess of 75 seconds. Dip the viscosity cup into the material and fill up. Time how long it
takes for the viscosity cup to empty (Fig.3).
Using the above chart (or manufacturer’s instructions) as a guide determine if the material
requires further thinning, if so then thin accordingly.
Some paints are outside the ranges above. Please contact our helpline for further
information.

OPERATION

PREPARATION

G Fill the paint container with the material to be sprayed. DO NOT OVERFILL above MAX level indicator. Push

the Feed Tube firmly into the base of the spray applicator body and re-fit the paint container into the spray
applicator body. (See exploded view on page 8 to show the fitting detail for the different spray applicator
types.)

G Unwind the hose from the Carrier Stand & screw the motor end of the hose to the outlet port at the front of

the turbine unit. Connect the spray applicator end of the hose to the spray applicator using the quick release
connector. Uncoil the power cord and plug it in to a suitable power outlet.

ALWAYS KEEP THE MOTOR UNIT AS FAR AWAY FROM THE SPRAYING AREA AS POSSIBLE TO
PREVENT PAINT CONTAMINATING THE MOTOR.

TAPE ANY AREA YOU DO NOT WISH TO SPRAY.

Once you have set up ready to spray, switch on the unit. No paint will be sprayed until the trigger on the spray
applicator is gently pulled. Before starting any work on spraying actual objects we suggest you spend some
time practicing on cardboard or newspaper until you have got used to how the spray applicator works.

SETTING UP YOUR SPRAY APPLICATOR

G Choose the best Needle & Fluid Tip for your application.

Your Spray Port is supplied to you with a 2.0mm diameter Needle & Fluid Tip. This is a good size for most
applications. However, there are other sets available to cater for a wider range of materials that you may want
to spray. In general, the larger the diameter of the Needle & Fluid Tip, the more suitable it is for higher viscosity
materials. The larger diameters also allow a greater volume of material to be applied. The smaller diameters
are more suitable for low viscosity materials & lighter application. For the Spray Port type “P”, Needle & Fluid
Tip sets are available at 1.0mm and 1.5mm diameter. For the Spray Port type “A”, Needle & Fluid Tip sets are
available at 1.0mm, 1.5mm and 2.5mm diameter. See page 8 for details.

end of each spray
movement to avoid
excessive paint and drips

SPRAY PATTERNS

Fig.4

The spray applicator has 3 different spray patterns – Horizontal,
Vertical and Round (Fig.4)
The horizontal and vertical are recommended for large surfaces.
The round spray is used for small objects or for areas - such as

Vertical Jet Round JetHorizontal Jet

corners – that are difficult to reach.
To adjust the spray pattern, loosen the Air Cap Ring (1), adjust the position of the Air Cap (2) to obtain either a
vertical, horizontal or round pattern then re-tighten the aircap ring.

PAINT VOLUME

Fig.5(a) shows the Air Volume Control Valve which regulates the flow of air to the gun.
When the Valve is fully open you will achieve maximum coverage. To achieve this
rotate ‘fully’ anti-clockwise. This is to be used in conjunction with the Fluid Adjusting
Screw for best results.
The volume of paint sprayed is easily adjustable (Fig.5b). Completely close Fluid
Adjusting Screw (B) by turning this clockwise as far as it will go. Whilst pulling the
trigger, begin turning the adjustment screw counter-clockwise until the volume of paint

ig.5

F

you require is obtained. If the paint spray is too wide or contains too much paint turn the
Fluid Adjusting Screw clockwise again. Once the correct spray pattern & paint volume is obtained, you are
ready to begin spraying.

SPRAYING

SPRAYING TECHNIQUE

1. To obtain the best results always keep your spray applicator level and spray equally from side to side

or up or down 25-30cm from the surface. Avoid spraying at an angle as this will lead to runs on
the surface (Fig.6a).

2. Let your arm control the left to right movement rather than your wrist as this will aid even paint distribution

over the whole area (Fig.6b).

3. Do not tip the sprayer to more than 45oangle when the motor is

switched OFF. You can tip the spray gun at more of an angle when
spraying celings and decking etc, providing that the motor is
switched ON.

Fig.6a

Fig.6b

Fig.6c

HELPFUL HINTS

1. Evenly control the speed of movement of the spray applicator. A fast speed will give a thin coat and a slow
speed will give a thick coat.

2. Only apply one coat at a time. If a further coat is required follow the paint manufacturer’s instructions for
drying times.

3. If spraying small areas or objects keep the output setting low as this will avoid
excessive use of paints and will minimise overspray.

4. When spraying large areas or objects, it is best to use a criss-cross pattern,
either from left to right then up or down or vice-versa. This will ensure maximum
coverage (Fig.7).

5. Avoid stopping and starting when spraying as this can lead to too much or not
enough material on a surface.

6. To ensure edges are covered, commence spraying just to the side of area being
sprayed.

7. CLEAN SPRAYER AFTER EVERY USE (SEE CLEANING INSTRUCTIONS)

CLEANING INSTRUCTIONS

Remember to disconnect the unit from the mains power when undertaking any cleaning of the Spray Port.

THE SPRAY APPLICATOR MUST BE THOROUGHLY CLEANED IMMEDIATELY AFTER USE. IF THE
PAINT DRIES INSIDE THE GUN, CLEANING WILL BECOME MUCH MORE DIFFICULT AND MAY RENDER
THE APPLICATOR INOPERABLE. THIS IS NOT COVERED BY WARRANTY.

The spray applicator is the same as a paintbrush, if it is not cleaned it will go hard and can become useless.
You must therefore clean this out after use.

MAINTENANCE

SPRAY APPLICATOR

G Keep the internal workings of the spray applicator clean. The spray applicator should be thoroughly

cleaned after each use. Follow the cleaning instructions on page 6 with reference to the drawings
on page 8

G Check the needle and fluid tip on a regular basis for excessive wear, and replace as necessary. See the

cleaning instructions for the correct procedure for removing these parts. Replacement needle sets are
available from Earlex Ltd.

G Keep all moving parts lubricated with a light smear of ʻsilicone freeʼ grease.

G Lubricate the gland washer, after each time you clean it, with a light smear of ʻsilicone freeʼ grease.

G Check there is no leakage from the gland washer. If there is, tighten the gland nut a little to ensure a seal

with the needle. Do not over-tighten this nut, also ensure the gland washer has not dried out. If it has,
lubricate it as above.

TURBINE UNIT

G Check the condition of the cartridge filter that is housed in the front cover. This is easily removed by sliding

it upwards. If it is clogged, remove it and blow out using an airline or washed out using a mild detergent if
necessary.

G Keep the outer surface of the air hose free from harmful substances such as petrol, automotive coating

thinners, paint strippers & oil. Prolonged exposure to such substances may cause irreparable damage.
Always check and clean off any excess immediately.

G Check the condition of the power cord regularly. If there are any cuts or serious abrasions to the outer

sheath, replace it immediately. When the unit is not in use, keep the power cord coiled around the brackets
at the back of the turbine case. When the unit is being used, protect the power cord and any extension cord
from damage that could be caused, for example, by traffic or hazardous substances.

The turbine unit can only be fully serviced by authorised service agents.
