Do
not touch or handle the hot parts of the unit until they have cooled down.
When the unit is to be out of service for over FOUR weeks, you must replace the products
contained in the unit with DOTP plasticizer.
Follow the steps given below to replace the products with DOTP plasticizing agent:
NOTE:
If the products contained in the unit can be reused, save them to suitable
recipients, following the instructions of the supplier.
a) Perform the cleaning procedure for hoses with recirculation (see

).
b) Fill the product tanks with DOTP cleaning agent (approx. 5 litres).
c) Open the manual purge valves located under each tank.
d) Make sure the recirculation taps are closed.
e) Rotate the power switch to the ON position.
f) Press the CONTROL POWER and MOTOR buttons.
g) Press the RETRACT button and wait for the proportioning pumps to descend into the
retract position.
h) Press the RETRACT, MOTOR and CONTROL POWER buttons to stop the
proportioning pumps.
i) Rotate the power switch to the OFF position.
j) Reduce product pressure by opening the recirculation taps and then closing them.
To prevent product leakage and the premature wear of pump packing seals, do not
reduce pressure to zero. We recommend keeping the system at a minimum pressure of
30 bars to prolong the service life of packing seals.
Proportioning pumps, heaters and hoses should always be filled with DOTP plasticizer when the
unit is not in use.
Never leave the unit or its hoses empty of product or DOTP plasticizer.
NOTE:
Never use liquids not recommended or not approved by HI-TECH. Never use
approved liquids that have been contaminated with water or ISO/POL. If you are not sure
in the quality of the liquid, you are going to use we strongly recommend that you check
the machine 2-3 times every 2 weeks after you have filled it by recirculating through
heated hoses (see p.34) and/or hoses with recirculation (see p.35) with fresh plasticizer
unless you make sure the liquid that comes out is completely pure and clean.
