Installation:
Installation should only be performed by people trained in electrical
hookup.
Keep in mind the minium bending radius. Once the part is bent
do not attempt to bend again.
Do not bend the adpater head or the first 5mm (.197”)
from the head.
Do not hold onto the connection head with a clamping method.
Only Use Non-Electrically conductive sprays and pastes for installation.
Heaters should be installed with a holding device. Higher operating
temperatures may cause the heater to lift off the tool causing
premature failure and false thermocouple reading
Heaters should be installed byn screwing on to tool. Never open
the ID of the heater by twisting as it will not fit correctly
and fail prematurely.
Temperature
controllers :
Temperature Controllers have to be matched to the heaters amp
load with an appropriate thermocouple sensor input.
Only use controllers that include a “Soft Start”
function. this will allow the heater to burn off any moisture
inside before applying full voltage.
Connections
:
Installation must protect adpater head and lead connection
areas from liquids and gasses to avoid short circuits.
If using a separate thermocouple be sure teht the TC is not
electrically grounded to the heater casing which could cause a
feedback to the controller inputs.
Watch sharp edges along the lead wire path.
Be mindfull of the maximum temperature of the lead wires during
planning to avoid melting during operation.
in cases where the heater is using the casing as the second
power lead, the tool temperature must stay below the corrosion
point.
Voltage differnces have a dramatic effect on wattage output
and heater life. Be sure the voltage is correct for the heater
design. you will find the designed voltage stamped onto the heater.
If using the internal thermocouple please be sure to follow
the standard wiring polarity. If teh temprature readiong drops
after power is applied the most common
cause is the thermocouple is wired backwards.
Operation
:
All installations must be electrically grounded.
Do not touch the heating elementy while in use - they get very
hot.
Please mount the heater so that ther is no chance of fire from
flammable material.
Storage
:
Store at room temperature in a dry location.
General
Information :
Please be sure to check over the order confirmation for check
information concerning operation or special applications.
If the lead wires are supplied without insulation or with removable
sleeves the customer must take care to insuret o insure their
protection from electyricity
