and wait at least four hours before starting to allow the electric heater
inside the compressor warm up the oil.
• If not, there will be oil entrainment problems at compressor start up.
• Make sure that the condenser cooling water is on.
• Remove the observation plug (pos. 27) from the observation port on the
front door.
• Switch on the mix pump button (pos. 3) which will also start the booster
pump (centrifugal pump). In case the booster pump has been wired
separately, start the buster pump first.
• Turn the “Production - C.I.P.” switch in the “Production” position (pos.
15) and switch on the button “Pump P1”.
• Continue to run the pumps until the product level in the inner cylinder
has reached the observation port.
• Stop the pumps (pos. 1)
• Replace the observation plug (pos. 27).
• Set the desired viscosity ( in % - max 100%) on the viscosity controller
(pos. 9). See Paragraph 9.3.4. “ Viscosity setting & adjustment “. The
set point entered by the operator appears in the display marked "w".
To obtain the desired product stiffness, control the refrigeration pressure
by turning the manual refrigeration control counter-clockwise or
clockwise (pos. ..).
