Pro Spray – Washing and disinfection stationUK2.0 WARNINGS READ THE FOLLOWING WARNINGS BEFORE PROCEEDING TO INSTALL OR DOMAINTENANCE WORK ON THE STATION.- Make sure that the water supply pressure is between 20 (1,4 bar) and 90 PSI (6,2 bar).- Make sure that the water supply temperature does not exceed 140°F (60°C).- The plumbing fittings in the station have been tested for use with the most common liquiddetergents mixed with water. Check that the detergent used is compatible with brass andpolypropylene.- Install the station near a connection point for the water supply.- Fit the guard to facilitate cleaning of surfaces and make the plumbing fittings accessible forreplacing dilution tips and routine maintenance. WARNING: BEFORE WORKING ON THE STATION UPSTREAM OF THE TAP, SHUT OFF THEWATER SUPPLY. Check the model of the equipment bought, when using the dosage calibration referencesindicated in this manual.

Pro Spray – Washing and disinfection stationUK3.0 TECHNICAL INFORMATIONPro Spray provides the following flow rates (the values shown in table 1 only apply when mixing one product at atime):Dynamic pressure upstream of the PRO SPRAY11.6 PSI (0.8 bar) 29.0 PSI (2 bar) 40.61 PSI (2.8 bar)Flow Rate in GPM 2.6 3.6 4.8Flow Rate in l/min 9.8 13.6 18.2Table 1 WARNING: OPENING BOTH THE CONTROL VALVES AT THE SAME TIME WILL LEAD TO ASLIGHT REDUCTION IN THE FLOW RATE AND MAY RESULT IN VARIATIONS IN THEPERCENTAGE OF PRODUCT MIXED.The degree of dilution required can be obtained by using one of the 15 calibrated nozzles supplied. The diameterof these nozzles decreases and they are color coded. Table 2 indicates the indicative degree of dilution for fluidswith varying viscosities.A degree of viscosity of 1 cps (centipoises) is typical for water, engine oil has an average viscosity of 75 cps, andthe approximate viscosity of most detergents used for washing dishes is 200 cps.Dilution ratio forTipsvarious degrees of viscosity1 cps 75 cps 200 cps# Color oz/Gal gr/l Ratio oz/Gal gr/l Ratio oz/Gal gr/l Ratio1 No tips 11.64 90.91 11:1 2.98 23.26 43:1 1.208 9.43 106:12 Grey 9.85 76.92 13:1 2.56 20.00 50:1 0.941 7.35 136:13 Black 9.14 71.43 14:1 2.37 18.52 54:1 0.928 7.25 138:14 Beige 7.11 55.56 18:1 2.10 16.39 61:1 0.914 7.14 140:15 Red 5.57 43.48 23:1 1.94 15.15 66:1 0.908 7.09 141:16 White 3.56 27.78 36:1 1.80 14.08 71:1 0.895 6.99 143:17 Blue 3.20 25.00 40:1 1.60 12.50 80:1 0.883 6.90 145:18 Tan 2.78 21.74 46:1 1.39 10.87 92:1 0.877 6.85 146:19 Green 1.83 14.29 70:1 1.22 9.52 105:1 0.810 6.33 158:110 Orange 1.32 10.31 97:1 1.00 7.81 128:1 0.624 4.88 205:111 Brown 1.07 8.33 120:1 0.80 6.25 160:1 0.516 4.03 248:112 Yellow 0.85 6.67 150:1 0.59 4.63 216:1 0.753 5.88 270:113 Aqua 0.62 4.88 205:1 0.43 3.33 300:1 0.343 2.68 373:114 Purple 0.43 3.33 300:1 0.34 2.65 378:1 0.277 2.16 462:115 Pink 0.24 1.89 530:1 0.23 1.78 563:1 0.183 1.43 698:1Table 2 – The dilution values given in this table are measured at a flow rate of4.23GPM (16 l/min) upply pressure of 40.61 PSI (2.8 bar), with a suctionheight of 5 feet (1,5 m).A nozzle is also provided that has a transparent colored tip without any hole that can be drilled to obtain acustomized degree of dilution.ProSpray 1 and 2 Cod. 0000136609 rev. 1.2 4

Pro Spray – Washing and disinfection stationUK4.0 INSTALLATION WARNING: Before proceeding with installation read all the relevant paragraphs carefully.Pro Spray must be installed in a position in which it can easily be connected to the water supply, with the hosebracket not far from the station.Before finally fixing it in position check that the taps can be opened and closed easily, that exposed surfacescan be cleaned quickly, and finally that routine maintenance can be carried out on the filter and nozzles.4.1 Recommended installation layoutFigure 1: Fitting diagram- Fit the unit and the hose bracket on the wall using the wall plugs supplied in the pack (Fig 2).Figure 2: Fitting diagramProSpray 1 and 2 Cod. 0000136609 rev. 1.2 5

Pro Spray – Washing and disinfection stationUKOnce the station has been installed all maintenance must be carried out by simply releasing the handles andthe front cover. The Pro Spray must not be removed from the wall (Fig 3)Figure 3: Sequence of steps for opening the station- Choose the appropriate dosing nozzle and fit it at the inlet to the non-return valve after removing the elbowconnector, as shown in Figure 4.Figure 4: Removing the dosing nozzlesProSpray 1 and 2 Cod. 0000136609 rev. 1.2 6

The hose for the water supply connection must have a ¾” male thread in GHT at the outlet end.1) Insert the washer with the filter in the seating in the ring nut. (fig. 5-1)2) Take the water supply connection hose to the ring nut on the top left of the Pro Spray3) Turn the ring nut until the hose if gripped tightly. The washer must be compressed slightly, guaranteeingthat the connection is watertight. (fig. 5-2)4) Apply slight pressure to insert the suction hoses (¼” ID - ⅜“ OD – 6x9mm) (fig.6).5) Insert the washer in the rotating ring nut and screw on the rubber delivery hose (fig.6)ProSpray 1 and 2 Cod. 0000136609 rev. 1.2 7
