| Maintenance and trouble
shooting for prolonging heater life |
1.
Regulate Voltage. A 10% variation in
voltage results in a 20% variation in
power.
2. When attaching the
lead wire to the terminals, excessive
turning pressure can cause breakage of
the terminal resistance wire.
3. A ¼" gap should
be maintained at the opening when
operating. Retightening is not normally
required, however, if the operating
temperature is changed the clamp bolt
should be checked. |
4.
Any material which can be carbonized such
as dirt, oil, plastic, etc., should not
be allowed to collect on the heaters.
5. Select a heater to
match the diameter of the cylinder. In no
case should heaters be used that are too
large.
6. Match the heaters as
closely as possible to the actual load
requirement to reduce cycling.
