Safety Warnings!
JTR-H Model JTR-H & 901-JTROwner’s Manual
Failure to abide by any of the safety warnings could result in serious injury or death.General
} Improper selection, installation, maintenance, misuse, or abuse of regulator can cause death, serious injury and property damage. } Do not exceed any equipment pressure or temperature ratings. } Do not use the regulator as a shut-off device. Prior to use in a system, a properly sized relief device is to be installed which limits the use
to 111% of the Maximum Allowable Working Pressure (MAWP). } Surface temperatures will approach temperature limit stated in technical specifications. Gloves may be required for handling or
adjustment. } Do not install the regulator in an enclosure that is heated above the regulator’s maximum ambient temperature. } Apply pressure gradually, avoiding a sudden surge of fluid or pressure. } Not designed for external fire

Safety Warnings (Continued) Failure to abide by any of the safety warnings could result in serious injury or death.Electrical
} Electrical power must be “OFF” before and during installation and maintenance. } All appropriate national, state and local electrical codes must be followed.
For Model JTR-H } The power supply is with the help of a silicone cable, notch and oil resistant. The cable is intended for installation inside a rigid metallic
conduit, cable tray or a similar method which provides sufficient mechanical strength to the cable against stress and bending. Grounding to be provided at the final location of installation.
For Model 901-JTR } Do not remove the temperature controller from the instrument enclosure; the wires may disconnect from the controller terminals. } Do not exceed 5 minutes with power without fluid flow or the thermal cutoff will open the circuit. } Sealing fitting must be installed with access allowing the dams to be made and the sealing compound to be properly poured. } All unused conduit openings must be plugged. Plugs must be a minimum of 1/8” thick and engage a minimum of 5 full threads.

Installation InstructionsWARNING - Electrical power must be “OFF” before and during installa-tion and maintenance or personal injury may result
Caution } Do not install the regulator in an enclosure that is heated above the regulator’s maximum ambient temperature. } Do not plug the atmospheric reference port for the regulator.
Step 1. Depressurize the system } Valve off the sample flow prior to installation of the Genie® Heated Regulator..
Step 2. Connect the Genie® Pressure Regulator } The regulator’s inlet and outlet ports are labeled. Connect tubing from the sample stream to the Inlet port (must have a minimum inlet pressure
of 300 PSIG, consult factory for applications with a lower pressure). Connect tubing from the outlet port to the next device in the sample system.
Step 3. Connect PowerModel JTR-H
} Refer to the INTERTEC literature provided with the unit for electrical wiring.
Model 901-JTR } With all electrical power off, connect the power source to the wire pigtail as follows: black wire to line/hot, white wire to neutral, green wire to
ground/earth. } A sealing fitting is required on the AC power supply to the enclosure. } Add fiber and sealing compound to the sealing fittings. Sealing fittings are approved for use in hazardous locations only when fiber and sealing
compound are used to make the seal. } The regulator’s controller is preset to 300°F. If a different set temperature is required, remove enclosure cover and make adjustments using
arrow keys. Replace enclosure cover when finished. } Allow the regulator to be powered for 2-5 minutes before starting flow through the regulator. Do not exceed 5 minutes with power without
fluid flow or the thermal cutoff will open the circuit.
Step 4. Establish Flow } To allow sample flow, slowly open external valving.
Step 5. Adjust Pressure } Turn off electrical power to the regulator, and take precauitons to prevent burns. The regulator will be HOT. } Turn the pressure adjustment screw located on top of the regulator to adjust the pressure while gas is flowing through the regulator. To raise the
outlet pressure, turn the screw clockwise. To lower the outlet pressure, turn the screw counterclockwise } To allow sample flow, slowly open external valving.
Note: At high supply pressure, a sudden change may be observed on the downstream pressure gauge as the valve stem moves away from the seat. Slight re-adjustments may be necessary until the pressure and flow have equilibrated.
} Tighten the pressure adjustment screw lock nut firmly against the washer to prevent unintended changes in pressure adjustment.

} Frequent inspection should be made. A schedule for maintenance checks should be determined by the environment and frequency of use. It is recommended that it should be at least once a year.
} Perform visual, electrical and mechanical checks on all components on a regular basis. } Visually inspect for undue heating evidenced by discoloration of wires or other components, damaged or worn parts, or leakage
evidence by water or corrosion in the interior. } Visually inspect to make sure that all electrical connections are clean and tight and that the device is operating properly.
} Contact the factory for evaluation of any failures or needed repairs.
