COMMANDO
®
equipment is not designed to satisfy any particular food safety
standard, therefore users should carry out their own assessment of this, if relevant.
Where product safety is a factor, only use cleaning water from a potable source.
Only use cleaning chemicals which are “food safe” and ensure all residues are
rinsed and removed prior to putting the equipment back into use.
Flush/purge machine with clean/ potable water prior to each use.
Carry out the specified daily checks and periodic maintenance to keep the machine
in safe working order.
Freezing
Ensure that the machine is protected from freezing which can cause catastrophic
damage, as detailed in section 7 of this manual.
Should a pump become frozen, do not attempt to start it.
Allow to thaw over time in a warm environment and inspect for damage before use.
Never attempt to thaw using heat sources which themselves could cause damage or
fire.
