6.3 Correcting SPEED COOLER faults
Problem Possible cause Solution / Correction
No cooling, or
cooling capacity
too low
System with cooler has not
been bled
• Bleed (see below)
No water or too little water in
the tank
• Top up with a mixture of water and antifreeze until the
cooling coils are well covered.
Mixing ratio of water: antifreeze = 3 : 1
Water pump with drive motor
does not work
• Use a screwdriver to turn the motor by the vanes (see
below)
Water pump defective (for
example, from running dry for
too long)
• Send the unit to the manufacturer for repair
Water tank or cooling spirals
in tank frozen
• Allow to thaw out and fill with water/anti-freeze mixture.
Mixing ratio water: antifreeze = 3 : 1
Too little throughput in the
water circuit
• Check the throughput:
Disconnect the water return line
switch on cooler
Flow rate min. 2 l/min
• Check that the hoses are not kinked.
• If no improvement:
Send the cooling system back to the manufacturer for
checking
Wrong power supply • Check voltage
see rating plate
Heat exchanger dirty • Clean the cooling fins with compressed air
Air circulation at the SPEED
COOLER is hindered.
• Check that enough free space is available (see also the
notes on setting up)
Compressor has overheated,
thermal cut-out has tripped
Ambient temperature too high,
compressor defective
• Switch the cooler off, wait 15 minutes and reset the ther-
mal cut-out. If the thermal cut-out trips again, the compres-
sor is defective. Send the cooler for repair.
Cooling body
leaking
Cooling body set on hot chuck
with cooling system switched off
→ seal melted
• Exchange the cooling body in replacement
Water tank leaking Pinch-type connection has
come undone
Brazed joints have failed
• Tighten up the connection
• Send the unit to the manufacturer for repair
Cooling body is
sweating
Water temperature has been
set too low
• Regulate the cooling power (see below)
Thermostat defective (does not
switch off)
• Send the unit to the manufacturer for repair
No water or too little water in
the tank
• Top up with a mixture of water and antifreeze until the
cooling coils are well covered.
Mixing ratio water: antifreeze = 3 : 1
