** REMOVE THE CLEAR HEATER / SENSOR PROTECTOR SHEET BEFORE OPERATING THE DRYER **
(protector sheet is located between the heater face and the sensor bracket)
- At the end of all shifts and / or production runs, follow the Dryer Shutdown Procedure posted on the front of the
dryer and in Dryer Operation.
- Any restriction in the dryer exhaust may result in excessive heat buildup within the chamber.
More information in Dryer & Exhaust Hood Ducting page.
Before starting production, the operator must check that all covers and guards are in place, no material has been left
on the conveyor, and the work area is clear of obstructions.
Switch on and verify conveyor belt is moving before turning on the heat.
Allow dryer to cool to 300°F (149°C) before switching off conveyor.
Always turn off power at the main disconnect at the end of production.
In case an abnormal symptom occurs, for example excessive vibration, noise, and strong smell or smoke develop-
ment, turn off the VASTEX Conveyor Curing System and contact a qualified technician.
Immediately turn off the VASTEX Conveyor Curing System if products become jammed in the drying chamber or
conveyor belt.

Assembly (1of5)
1) Cut straps with tin snip 2) Using crow bar or claw hammer, pry off
plywood carefully
3) Remove all wood supports
Caution!
The heating chamber sits on top of the conveyor pins. Lifting the chamber will separate the chamber from conveyor.
4) Remove front and rear conveyor pieces, additional
(optional) legs, and any boxes shipped underneath
chamber.
-Use 9/16 or 15mm socket/wrench to remove lag bolts
5) Remove side runner to slide
machine off pallet.
-Use 9/16 or 15mm socket/
wrench to remove lag bolts
Tools Needed: (1) Crowbar or Claw Hammer, (2) 9/16” open end wrenches, (1) 7/16” open end wrench or socket,
(1) 1/4” nut driver or flat blade screw driver, (1) 1/8” allen wrench
Econored-II-54 shown for illustration purposes. Econored II and III are assembled and operated
in the same manner. Econored-III has a 3rd heater and is 18”(45.7cm) longer than Econored-II

DO NOT LIFT FROM CONVEYOR BED
4) Position front end section (section without motor)
on the floor in the front of the dryer as shown. Lo-
cate 3/8 bolts, square washers, and serrated lock-
ing nuts from hardware bag. Two 9/16” wrenches
are required. Raise one side and attach with hard-
ware as shown below through the upper mounting
hole. Do not tighten at this time. Carefully raise the
other side and insert both upper and lower bolts
and nuts. Install remaining bolt on first side and
tighten all bolts. Use the same procedure for in-
stalling rear end section. Be sure all end section
mounting bolts are tight before continuing.

Assembly (3of5) Ducting
5) Install Dryer ducting. CFM cannot be reduced by more than 10% at exit of ducting. An exhaust booster must be
used if CFM is reduced more than 10% due to length of duct or amount of bends. Please seek professional ad-
vice if this is not your area of expertise.
Proper venting is important for safety of operator and work area as well as quality of product.

7) Have a licensed electrician complete the electrical hook-up and fill out the warranty card. Send it back to Vastex
to validate your warranty. A wiring diagram has been included with this manual, and is also adhered to the inside
of the control box cover.
8) Plug the wire from the conveyor motor into the motor cpc connector. (Shown on Controls page 2)
9) Have a licensed electrician test the shops voltage at the machines disconnect, for shops with less than 240V ser-
vice, it is necessary to auto tune your controller. This procedure can be found in the Troubleshooting section.
Please record your shops actual voltage here:______________________

11) The belt needs to be tightened and adjusted. To tighten and adjust the belt, use the Aligner Bolts. To raise the
Aligner, turn the Aligner Bolt clockwise with a 7/16” wrench. To lower it, turn it counter clockwise. Start with the
belt centered on the pulley.
12) To track the belt and continue machine setup, follow Startup Procedure in Operation page 1. To track the belt,
follow instructions found on Belt Tracking page.
10) The belt needs to be installed as shown in the diagram below. For dryers with an (optional) rear drive idler,
please see Optional Drive Idler page. Be sure the belt is routed over all braces on the conveyor and over the
Aligner. To connect your belt, align the Alligator Lace and install the pin.

Belt Tracking
(Move in small increments while belt is moving. Do not leave
conveyor running unattended.)
If the belt is slipping, add belt tension by raising equally both
sides of aligner roller. 1”-2” of belt sag at the bottom side is
desirable. To raise roller turn adjustor bolt clockwise.
Belt moving to the left, raise left side of aligner by turning
aligner bolt clockwise 1/2 turn at a time.
Belt moving to the right, raise right side of aligner by
turning aligner bolt clockwise 1/2 turn at a time.
If belt is tracking off center at the drive roller, slightly loosen
bearing bolts, (2) 1/2” wrenches needed. Turn adjustor screw
clockwise to move belt toward motor end of pulley and coun-
ter clockwise to move belt away from motor end of pulley,
retighten all bolts. Recheck belt tracking at front end.
Note: Do not over-tighten belt, 1” to 2” belt sag is desirable.
