Ingersoll-Rand 651747-X-B Power Supply and Installation, AIR and Lube Requirements, Maintenance

POWER SUPPLY AND INSTALLATION

NOTE: The power supply cable is not furnished with the unit and must be supplied by the customer.

Do not use neutral as earth ground. A single phase power / earth ground is required. If this is not available, use a transformer to obtain single phase power.

Provisions should be made for a quick disconnect or shut￿off of all electrical power to this unit.

All wiring must comply with all local and / or national electrical codes.

•Electrical codes that apply must be strictly adhered to. Failure to do so may lead to shock hazard or serious injury.

•Some local electrical codes may require the installation of rigid conduit.

•The installer of this system assumes full responsibility for compliance with these codes.

•Aro is not responsible for accidents resulting from improper installation of components or hardware.

•No electrical power should be in the system at the time the cover is re￿ moved.

MAINTENANCE

NOTE: The (22) fluid track is a cast assembly and cannot be disassembled for cleaning. Do not allow material to solidify inside the heater. Flush the paint heater with the proper solvent immediately following each use.

CAUTION Shut the electrical supply off and relieve all pressure from the system before servicing any part of the fluid heater system.

CLEANING

1.When cleaning the fluid heater, use only solvents compatible with the material being pumped.

2.The fluid heater should be flushed with solvent when changing medias, or when it is not being used for a period of time.

NOTE: For other maintenance problems, see ``Trouble Shooting", page 4.

DISASSEMBLY

NOTE: The following procedure is for the repair of the (24) heater cartridge as￿ sembly, (29) thermostat or the (23) cutoff assembly.

1.Relieve all fluid pressure in the system.

2.Rotate the (17) adjusting knob counterclockwise to the ``off" position.

3.Disconnect the power supply to the fluid heater assembly.

4.Disconnect the fluid lines.

5.Remove the six (2) cap screws.

6.Remove the (20) cover.

7.Remove the two (12) machine screws and (11) lockwashers from the (21) housing, which retain the thermostat assembly.

8.Remove (as one unit) the (10) terminal block, (29) thermostat and (13) mounting plate by carefully lifting it out and removing the power lead wires (1 and 3) from the first two positions on the (10) terminal block (re￿ fer to figure 3).

9.Remove the (24) heater cartridge assembly leads from the (10) terminal block third and fourth positions.

10.Carefully finish removing the assembly by pulling the thermostat capil￿

lary tube out of the (22) fluid track body.

NOTE: Special care must be taken not to sharply bend or kink the capillary tube which will ruin the thermostat. Do not use pliers or other tools which may also damage the tube.

11.Remove the (28) indicator lamp leads from the (10) terminal block third and fourth positions.

12.Unscrew the (15) site plug to remove the (28) indicator lamp from the assembly.

13.Remove the (23) cutoff assembly leads from the (10) terminal block sec￿ ond and fourth positions. Carefully remove the (23) cutoff assembly from the (22) fluid track.

OPERATING INSTRUCTIONS

START/UP PROCEDURE

1.Fill the system with fluid.

2.Circulate the fluid thru the system.

CAUTION Power should never be on when there is only solvent in the system. Solvents can expand if there is no circulation, causing excessive and hazardous pressure in the system.

3.Turn the power on.

4.Set the thermostat just below the boiling point of the lowest boiling sol￿ vent in the coating material (see table above).

5.Allow fluid to circulate thru the heater for 5 ￿ 10 minutes.

6.Readjust the thermostat as necessary.

To adjust the temperature, turn the knob:

a.Clockwise - higher temperature

b.Counterclockwise - lower temperature

SHUTTING THE SYSTEM OFF

1.Allow the fluid to circulate for 5 ￿ 10 minutes after shutting the heater off, to cool the system.

2.Always leave the solvent or fluid in the heater.

HEATER CARTRIDGE REMOVAL

1.Pull the (24) heater cartridge assembly from the (22) fluid track. NOTE: If the

(24)heater cartridge assembly does not easily come out, do the following:

a.Remove the (25) pipe plug from the bottom of the (22) fluid track.

b.Carefully drive the (24) heater cartridge assembly out thru the top of the heater (toward the cover).

REASSEMBLY

1. Reassembly is done in the reverse order.

NOTE: Care must be taken to keep the (29) capillary tube away from the (23) cutoff assembly.

NOTE: When reinstalling the (20) cover, be certain the (17) adjusting knob is turned out. If the (18) screw is threaded in too far, it will inhibit the cover from properly sealing flat against the housing.

2.Rotate the adjusting knob clockwise out as far as it will go and turn it back in carefully to align the slots with the thermostat.

3.Apply Watt Lube to (24) heater cartridge assembly.

4.Apply Dow Corning 340 Silicone Heat Sink compound to the (29) ther￿ mostat probe and (23) cutoff assembly. This material increases the overall efficiency of the devices.
