After normal usage, the heater cartridges within the manifold will have to be replaced. Whenever
the machine is being turned “OFF”, be sure to always let the pneumatics continue to run until the
cartridges have reached room temperature. Turning the pneumatic supply to the machine “OFF”
while the cartridges are still hot will damage the heaters and the pneumatic lines. There are a
couple of signs that a cartridge has burned out. If you suspect that a cartridge has burned out, the
best way to verify is by checking for current through the cartridge lead wires. This can easily be
checked with a current clamp meter when the system and heaters are turned on.
Since the life expectancy of the cartridges are consistent, it is best to replace both cartridges when
one has been determined to have burned out. In some instances, after one cartridge has burned out
the remaining cartridge works harder to compensate for the loss. This will shorten the second
cartridge’s life significantly. To replace the heater cartridges in the manifold, follow these steps:
1. Turn “OFF” and lock out the electrical and pneumatic supplies to the machine.
2. Remove the swing channel (front) shrouding to access the hot air manifold assembly.
3. In order to place the manifold back into its original place after being removed, you may wish
NOTE:
Only qualified and trained electricians should replace the heating
cartridges of the manifold assembly.
