system.
These instructions must be passed on to the end user where they should
be read before using this product. Failure to do so can result in serious
injury or death.

Failure to comply can result in serious injury or death:
STORED ENERGY AND HIGH TEMPERATURE HAZARDS
This product maintains molten plastic at high pressure. Use caution when
operating and servicing the system.
Physical contact with molten plastic may result in severe burns. Proper
protective equipment, including eye protection, must be worn. This product
has heated surfaces. Use caution when operating and servicing the system
to avoid severe burns. Proper protective equipment should be worn.

Failure to comply will result in serious injury or death:
ELECTRICAL HAZARDS
Improper voltages or grounding can result in electrical shock. Use only
with proper voltage and a proper earth ground.
To avoid electrical shock, do not operate product when wet.
Do not operate this equipment with covers or panels removed.
To avoid electrical shock, turn off main power disconnect and lockout /
tag out before servicing this device. Do not connect temperature sensors to
electrical power. It will damage the product and it can cause fire, severe
injuries or even death.
If green ground wire present wire must be connected to the ground.
Do not rebend rigid leads. Rebending leads might result in damage to circuit.
Product might absorb moisture when cool. Use low Voltage or power to drive

damage to this product.

NOTE: The expansion factor must be taken into consideration prior to machining for, and installing nozzle. This factor (BE) must
then be addeed to the nominal "A" dimension. Formula for determining this expansion is as follows:

BE= "A" dimension x 0.0000633 x (nozzle setpoint - 68 F).

EXAMPLE: Given a 2.500 Inch "A" dimension, with a nozzle setpoint temperature of 500
