The machine parts are protected by a moisture-free enclosure, which also reduces the noise level to a minimum (below 75 dB(a). The PR750H provides a non-stop supply of high-density dry ice pellets. The source of raw material for the production of pellets is liquid carbon dioxide preserved at low temperatures in a storage tank.
=G01-G1-MO1 for the extruder piston will extract until plug set point is reached and the hydraulic cylinder will again retract. This cycle will continue until a different step is selected. During production, it is possible to set the PR750H on standby.
The owner of the machine shall make sure that the operator, who is to work with the PR750H, fully understands the importance of studying the contents of this manual and comply with the SAFETY REGULATIONS described on the following pages as well as those placed on the machine.
While working with the conveyor system, the operator must wear protective gloves to avoid contact with the dry ice or with parts of the machine which are in direct contact with the dry ice. Version: PR750H Page: 10 of 21...
SAFETY OPERATION Emergency stop All equipment is connected to the general emergency system for PR750H. When an emergency-stop device is activated, all components located in the emergency zone will be disconnected from their power source.

Get a particle analysis of the oil if in doubt about the contamination degree. Cold Jet recommends that the owner has a spare parts package in stock, so repairs can be made quickly and with little loss of production time.
Protect all electronic equipment. All surfaces can be cleaned with a degreaser and acid-free oil. If the bottom of the PR750H is full of water/oil then there is a drain plug that can be found on the backside of the PR750H.
INSTRUCTION – UNPACKING AND PREPARATIONS BEFORE INSTALLATION Your new PR750H has been assembled as one unit. In order to avoid damages during transport, the PR750H has been bolted onto the transport pallet. Unpacking and Examination for Transport Damages 1. Examine the transport box for any damages that may have occurred during transportation.
Page 24
Installation of the PR750H The installation of the PR750H must be carried out by a Cold Jet service technician, or by a technician approved by Cold Jet.
Disconnect the power Disconnect the CO Drain the PR750 oil For handing of the PR750H read section INSTRUCTION – UNPACKING AND PREPARATIONS BEFORE INSTALLATION. The materials and oil must be disposed of according to the jurisdictional rules and regulations for proper disposal.
