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 cellulose then a cellulose 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. 3 N0151 07_05.qxd 16/01/2006 10:49 Page 4 IDEAL VISCOSITY Water based paints and 25 - 75 seconds Varnishes Manufacturers ratio emulsions Aluminium paints Manufacturers ratio Oil based paints 45 - 50 seconds Wood stains Manufacturers ratio 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 Fig.3 information. OPERATION PREPARATION 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.) 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 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.

Vertical Jet Horizontal Jet Round Jet The round spray is used for small objects or for areas - such as 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 Fig.5 trigger, begin turning the adjustment screw counter-clockwise until the volume of paint 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 45o angle 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 INSTRUCTI ...
