It is therefore prohibited to use non-original bags. The use of non-original bags voids the warranty on the machine as well as the ATEX certification. Formeco declines any responsibility for possible damag- es that, directly or indirectly, may be caused to persons or property as a consequence of the use of non-original bags. -

5.4. Solvent loading Pour the solvent to be distilled into the boiler up to the reference sign which indicate the maximum level. Make sure not to pour solvent into the vapour manifold: the first distillate would come out dirty. The machine is equipped with a lateral loading pipe for easy connection to the washing booth. 5.5. - Page 12 b.

Diathermic oil change Set up a collecting container under the machine to collect the used diathermic oil. Oil type: FORMECO LT200, MOBILTHERM 605, ESSOTHERM 500, SHELL ThermiaB, TOTAL Seriola 1510. For different brands, use diathermic oil with a cracking temperature higher than 320 °... - Page 19 1. Remove, by unscrewing, the oil bleeding valve (1); 2. Place the collecting container (2) and rotate the machine; remove the cover and unscrew the loading plug of the oil (3) to let the oil flow out. 3. Blow dry compressed air (4 ÷ 6 bar) in the plug to remove any formed debris. 4.
- Page 20 Normally when cleaning the element it is convenient to also change the diathermic oil and in this case it can be poured directly into the hole of the element. d. Reset the hour counter 1. Open the control box 2. Push the button A for resetting the hour counter. - 19 -...

Page 21: Vacuum Generator (Optional)
Vacuum distillation is used: preferably for solvents with a boiling point above 160 °C; obligatory with solvents with a boiling point over 200°C (the FORMECO distillation units operate at a maximum temperature of 200°C); when treating substances with a boiling point close to the auto-ignition point, for example mineral spirit with a boiling range of 150-195°C and an auto-ignition point of 254 °C... -

3. After about 10 minutes, the vacuum meter (10) should indicate the under pressure value at about -0.70 ÷ -0.76 bar; if the vacuum is lower, verify the connections to find the air leak. 4. It is possible to reduce the noise generated by the compressed air venturi, by connecting a 10x12 mm tube with a maximum length of 5 metres to the outlet of the economizer (5) ;... -
