You will find an overview of the lubricants used below:
The following can be used as grease in accordance with DIN 51818/NLGI class 3:
- Esso Unirex N3
- Tripol Molub-Alloy-Food Proof 823 FM*
When using white oil, note the following:
- The machine lubricants may only be topped up or replaced with lubricants from the same
manufacturer.
- Machines which have previously been operated using other lubricants must first be thor-
oughly cleaned before they can be operated using white oil.
Lubricants which are approved for use with foodstuffs in accordance
with USDA-H1 are marked with an asterisk.
The specified lubricants are used in the sealing chamber.
Coolant
The cooling system is filled with the manufacturer's filling P35. The manufacturer's filling is made
from the BP Thermofrost P concentrate (35%) and water (65%). When topping up or filling the
cooling system, this manufacturer's filling should only be used in the stated ratio, otherwise frost
and corrosion protection cannot be guaranteed. The manufacturer's filling guarantees an anti-
freeze effect to -15°C.
P35 is in water pollution category 1 according to VwVwS 1999. When
disposing of the fluid, observe DIN 52 900 (concerning propane diole and
propylene glycol).
Other concentrates may not be used as this can lead to faulty operation
or destruction of the motor.
