Dryer Assembly Instructions

1. Remove DRYER CHAMBER from the crate.
2. CONVEYOR DRIVE ASSEMBLY:
   • Locate the Assembly. It consists of a 4” roller and drive motor among other parts.
   • Fit the Conveyor Rails inside the rails protruding from the Dryer Chamber and using (6X) of the provided 5/16” Bolts, attach the assembly.
   • Route the plug connector through the holes in the Cross-Members.
   • Connect the plug to the socket on the heater frame. Push the connector until fully seated.
3. TAKE-UP ASSEMBLY:
   • Locate the Assembly. It consists of a 4” roller mounted through some sliding bearing assemblies among other parts.
   • Fit the Conveyor Rails inside the rails protruding from the DRYER CHAMBER and using (6X) of the provided 5/16” Bolts, attach the assembly.
4. CONVEYOR BELT:
   • You are going to need an assistant for this step in the assembly.
   • Loosen (but do not remove) the bolts holding the sliding bearing assemblies on the TAKE-UP ASSEMBLY.
   • Locate the end of the CONVEYOR BELT that contains the splice pin.
   • Remove the pin, but DO NOT bend or discard this pin. You will reinsert it later.
   • The TrueTrak™ Rubber Edge Guide on the CONVEYOR BELT is designed to ride in the grove on the Drum Roller.
   • Feed the CONVEYOR BELT through the DRYER CHAMBER then around an end roller and back through the lower chamber.
   • Bring the ends of the CONVEYOR BELT together. Use a straightedge on the Edge Guide side of the belt to assure alignment when you mesh the teeth of the splice. If you are just one tooth off, the BELT may jump the edge groove.
   • While your assistant holds the ends of the CONVEYOR BELT together, properly mesh the teeth and reinsert the splice pin. The needle-nose pliers will be needed for the last inch or so.
   • Move to the TAKE-UP end of your Dryer.
   • Pull on the Roller Drum by hand to remove some slack from the belt and tighten the bolt on the bearing assemblies. No need for super-human strength here: if it’s too tight, the splice can be damaged over time.=.

Connecting Unit to Power
This unit is not supplied with a power cord. Have a certified electrician connect the unit to power in accordance with local electrical codes.

Before servicing or cleaning, switch power OFF at the service panel and lock the service panel to prevent the dryer from being switched on accidentally. If the service panel cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

DO NOT OPERATE THE DRYER WITHOUT COVERS IN PLACE

1. Using a Phillips screwdriver, remove the CONTROL PANEL COVER.

2. Strip cord jacket exposing enough of the lead wire to connect to appropriate terminal blocks.
   Note : The ¾” starter hole for the cord is NOT appropriately sized. You may have to increase this hole size to fit your cord grip.

3. Insert and tighten green grounding lead wire from the cord into GROUNDING LUG or GROUNDING TERMINAL across from green wire.

4. Place the POWER leads into the open side of the large TERMINAL BLOCK and tighten the set screws. BE SURE NOT TO CLOSE WIRE INSULATION IN THE TERMINAL BLOCK. (FIG. 2 & 3)

5. Once all connections have been made, tug on the leads to make sure they are fully secured.

6. Replace the CONTROL PANEL COVER. Be careful not to pinch any leads.

Operating Instructions:

The RileyCURE FORCED AIR DRYER (Combination Forced Air / Infrared Dryer) is designed to cure both Plastisol & Water-Based screen print inks as well as Digital Ink-Jet printer inks with utmost efficiency. Two different temperature dials are available to allow for maximum production. By setting Zone 1 higher than Zone 2, your dryer will have a profile that plateaus, allowing faster cure times by obtaining higher shirt temps early in the process and holding those temperatures without surpassing scorching temperatures. The Forced Air is essential for all water-based inks, whether screen-printed or digitally printed. The blower constantly introduces fresh, hot, dry air into the curing chamber. It does not recycle saturated humid air within the chamber like other dryers. The Forced Air cannot be turned OFF as it is also used to insulate the dryer and keep the outside skin cool.

Operation

1. Flip switches for Conveyor Belt and Heat (if desired) to ON position.

2. The display on the temperature controller shows the current element temperature.
   Note : This is not the air temperature inside the dryer, but rather the temperature of the heating element itself.
   Press the , and keys to show and change the Set-Point
   Temperature then to enter.

3. The conveyor display on the speed controller is from 00 to 99. The correct speed will need to be tested and adjusted.

4. Press the + & – keys to adjust each digit.

5. Once the temperature has reached the Set-Point, allow an additional 5 minutes for the dryer to reach equilibrium.

6. If the temperature setting is changed, allow 5 minutes for the dryer to reach equilibrium (longer is fine too).

Listed below are suggested initial settings for your FORCED AIR DRYER. There are many factors that influence the curing of different inks. Test prints need to be produced and wash-tested to determine the best possible settings for your application.

Table 1 – Suggested Settings for Initial Startup.

Your dryer setting will likely be different than those listed above. This table is a suggested starting point. If the shirts are scorching, it is too hot. If they are not fully cured, the dryer needs to be turned up. Allow the dryer to ‘soak’ at the new setting for a few minutes before running the product through it at the new setting.
(TIP: Change only one setting at a time. Changing multiple settings can result in confusion and longer discovery of proper cure settings.)
Washing the garments is the definitive test of the effectiveness of the dryer settings. Test and retest until you have found a setting for your dryer, your shirts, and your inks. Your customers will appreciate it!

BASIC TROUBLESHOOTING

If the dryer does not hold temperature at the set-point (within 5° – 10°F), check the following components:

• Confirm the dryer is getting proper voltage. A drop in voltage will decrease the temperatures in the dryer.
• Reduce any drafts or air currents such as open doors, fans, and air conditioners that could be blowing into the chamber. Do not direct fans to the dryer. This will cause temperature variations in the chamber.
• If the temperature controller displays “OPEN”, then the thermocouple has failed or become disconnected. Replace if necessary.
• If the temperature does not rise at all or passes through set-point and continues to heat, Solid State Relay (SSR) may have failed. It can fail in the open or closed position. Replace if necessary.

If Conveyor Belt or Forced Air blower stops, check to see if the fuse on the backside of the Control Panel has tripped. Push to reset.

Control Panel Maintenance

Performed at initial installation, 30 days after initial installation, and 120 days after initial installation.

1. Turn OFF the power serving the main control panel which it is connected to the building‘s electrical distribution system. Unplug the unit.
   Note: Assure that appropriate “Lock-Out / Tag-Out” procedures are followed before conducting any of these activities.

2. After double-checking that the power is off, confirm that all electrical terminations inside of the main control panel are secure by checking the “tightness” of each termination screw (or wire nut as may be applicable) and then “tugging” on each conductor.
