INSTALLATION AND OPERATING INSTRUCTIONS UNCRATING Tools Required: 3/4" hex socket & ratchet driver, wood block 4" or 5" thick, a knife and a groove joint pliers, which will open to 1 3/8". 1. Remove and discard packaging. 2. The crate base is attached to the dryer by (4) cap screws driven upward from below the crate base. Remove crate base from dryer, by tipping dryer sidewise and place block under crate base rail in center of dryer.
VI. Floor C. A 10 in. (254 mm) clearance is required from top at all other points. This unit may be installed upon a combustible floor. Do not obstruct the flow of combustion and ventilation air. Maintain minimum of 1 in. (25 mm) clearance between duct and combustible material. Refer to the label attached to the Belt Guard on the rear of the dryer for other installation information and start-up instructions. 3. MAKE-UP AIR. Adequate make-up air (600CFM/DRUM (17 m3/Min.), 1200CFM/DRYER) (34 m3/Min.
should be made at the terminal blocks in the two control boxes on the rear of the unit using conductors rated at 75 C (167 F) and a wire size adequate to handle the amperage and voltage listed on the serial plate (see table on the next page for recommended minimum sizes). It is absolutely necessary that the dryer be grounded to a known (earth) ground (No. 8 AWG copper conductor recommended).
tend to collect lint, which will eventually clog the duct and prevent the dryer from exhausting properly. All elbows must be smooth on the inside. All joints must be made so the exhaust end of one pipe is inside the next one downstream. The addition of an exhaust pipe tends to reduce the amount of air the blower can exhaust. This does not affect the dryer operation if held within practical limits. For the most efficient operation, it is recommended that no more than 14 ft. (4.25 m) of straight 8 in.
Installation of several dryers, where a main discharge duct is necessary, will need the following considerations for installation (see Figure 3). Individual ducts from the dryers into the main discharge duct should be at a 45-degree angle in the direction of discharge airflow. NOTE: Never install the individual ducts at a right angle into the main discharge duct. The individual ducts from the dryers can enter at the sides or bottom of the main discharge duct.

TOUCH PAD DESCRIPTION INDICATOR LIGHTS (L.E.D.s) Description Cycle (1 through 5) These L.E.D.s are on solid when a particular cycle is chosen for operation or programming. Gas Valve This L.E.D. is part of the 4-digit numeric display and will be on solid during the drying part of a cycle when the gas valve does not need to be on. The L.E.D. will be blinking when the gas valve needs to be on. The L.E.D. will not be on solid or blinking (off) if the cycle is stopped, complete, in cool down, or terminated.
SWITCHES (Pushbuttons) - continued Description This touch pad switch allows the dryer controller to enter the temporary programming mode. Cycle This touch pad switch will stop the dryer during a dry cycle without clearing the present drying cycle if pressed once. If pressed and released twice, consecutively, the present dry cycle will be cleared. Stop Start This touch pad switch will start the operation of a dry cycle if pressed and released once.
OPERATING INSTRUCTIONS To dry a load of items, you must choose one of the five-programmed dry cycles. Each of these five dry cycles may be modified in two different ways to match your load. Please refer to the “Permanent Dryer Controller Programming” or “Temporary Dryer Controller Programming” section of this manual. There are two parts to each dry cycle. The first part is the heating time, which is when the gas valve is cycled on and off according to the temperature setting in the dry cycle program.
will repeat a total of 10 times, at which time the wrinkle free cycle stops. The cylinder will not rotate again until a new dry cycle is started. During the wrinkle free cycle the gas valve will not be operated and there will be no heat applied to the load. The word “donE” will also continue to flash and do so even after the wrinkle free cycle is finished.
TEMPORARY DRYER CONTROLLER PROGRAMMING The temporary programming mode will allow the change of the stored dry cycle settings in the dryer controller for one complete dry cycle. After the dry cycle is complete, the default settings that existed before the temporary change are restored. The temporary dry cycle can be stopped and cleared at any time during the dry cycle operation. To temporarily change a dryer controller cycle, follow the procedures below.
temperature L.E.D. will illuminate. The drying temperature will also be shown on the 4-digit numeric display. 6) Press and release the UP or DOWN arrow keys to change the drying temperature. Each press and release of the arrow keys will either increase or decrease the temperature by five degrees Fahrenheit or three degrees Celsius, depending on how your dryer controller is set up. Once either of the arrow keys is pressed, the temperature L.E.D.
PROCEDURE 1) After the load has been placed in the dryer, press and release the UP or DOWN touch pad key on the dryer controller until the L.E.D. for dry cycle 1 is illuminated. 2) Press and release the CYCLE key on the dryer controller touch pad. You will see the number “35” on the dryer controller display. The programming L.E.D. and dry time L.E.D. will be illuminated. 3) Press and release the UP arrow key on the dryer controller touch pad 10 times so the display will show a flashing “45”.
PERMANENT DRYER CONTROLLER PROGRAMMING The permanent programming mode will allow the change of the stored dry cycle settings in the dryer controller until the operator physically changes them again. The factory default settings can be restored in the dryer controller by pressing the default settings pushbutton on the back (component) side of the dryer controller circuit board. It is labeled and located at the lower middle side of the printed circuit board, as you face the component side of the board.
three degrees Celsius, depending on how your dryer controller is set up. Once either of the arrow keys is pressed, the temperature L.E.D. and the drying temperature on the 4-digit numeric display will flash. If you press and hold either arrow key down, you will increment (UP arrow) or decrement (DOWN arrow) your way through the available drying temperatures (105º Fahrenheit or 40º Celsius, up to 195º Fahrenheit or 91º Celsius).
2) Press and release the PROG touch pad key on the dryer controller. The dryer controller display will not change. 3) Immediately, press and release the UP arrow key on the dryer controller touch pad. The controller display will change from “LOAd” to “Prog”. You have now entered the permanent programming mode. The dry time L.E.D. will remain on and the programming L.E.D. will illuminate. 4) Press and release the SELECT/ENTER touch pad key once. The dry time L.E.D. and programming L.E.D.
SERVICING THE DRYER Note: A key with the markings “6324” is provided for service access to controller by a qualified person. This key should be stored in a secure place away from the dryer. Routine Non-Technical Maintenance and Cleaning: DAILY 1. Clean lint screens. Use soft brush if necessary. Failure to do so will slow drying, increase temperatures throughout the dryer and increase the risk of fire. Dryer must not be operated without lint screen in place.
Maintenance Requiring Technical and Mechanical Skills: Note: All procedures must be performed by a service engineer or competent person when the dryer is not running. (Disconnect power to dryer before beginning.) QUARTERLY 1. Check tumbler shaft nuts, and, if lose, retighten to 150 lb. ft. (200 Nm). 2. Check belts for wear needing replacement to prevent reduced performance. SEMI-ANNUALLY 1. Clean burners. Blow out burners, around primary air opening, and orifices with compressed air.
Instructions - Convert a Dual Voltage Stack Dryer from 120V to 208-240V with Neutral Wire Only 1. Remove incoming power from the dryer. Use a known working voltmeter to check power. 2. Remove the cover of the control box assembly from the dryer using a 5/16” wrench. 3. Move the black/blue wire from the N position of the main power terminal block to the L2 position of the main power terminal block in the control box assembly. See Figure 6 below. 4.
