Installation Pre-Installation Inspection Upon delivery, visually inspect the crate, carton and parts for any visible shipping damage. If the crate, carton or cover is damaged or signs of possible damage are evident, have the carrier note the condition on the shipping papers before the shipping receipt is signed, or advise the carrier of the condition as soon as it is discovered. Remove the crate and protective cover as soon as possible and check the items listed on the packing list.
Installation WARNING To reduce the risk of severe injury, clearance of tumbler cabinet from combustible construction must conform to the minimum clearances.

(51-102 mm) opening at top of machine to aid in removal or installation.
Installation Position and Level the Tumbler The tumbler may be moved with or without the skid. To remove the skid, unscrew the four shipping bolts, and discard them. To fit a 170 pound tumbler (with shipping skid) through an 8 foot (2.43 meters) high door, you must remove the front access panel. The upper 3 inches (76 mm) of the stove must also be removed on 170 pound gas tumblers.
Installation Required for CE Models Only WARNING The tumbler must not be operated if the airflow switch does not operate properly. Faulty airflow switch operation may cause an explosive gas mixture to collect in the tumbler. Once machine is installed, please be sure to complete the following items: ● Review and verify machine operation with customer. ● Leave all literature and a signed Declaration of Conformity with customer. ● Review machine warranty information with customer.
Installation Installing CE Gas Drying Tumblers WARNING To reduce the risk of electric shock, fire, explosion, serious injury or death: • Disconnect electric power to the tumbler before servicing. • Close gas shut-off valve to gas tumbler before servicing. • Close steam valve to steam tumbler before servicing. • Never start the tumbler with any guards/ panels removed.

Exhaust Requirements Make-up air openings with louvers will restrict air flow. The opening must be increased to compensate for area taken up by louvers. WARNING A drying tumbler produces combustible lint. To reduce the risk of fire, the tumbler must be exhausted to the outdoors.
Exhaust Requirements Alternate Venting for 120 Pound Tumblers WARNING The 120 pound tumbler is equipped from the factory to exhaust from the top; however, it may be converted to exhaust out the rear by doing the following (refer to Specifications and Dimensions section): Improperly sized or assembled ductwork causes excess back pressure which results in slow drying, lint collecting in the duct, lint blowing back into the room, and increased fire hazard. 1. Remove belt guard cover. 2.
Exhaust Requirements Individual Venting For maximum efficiency and performance, it is preferred to exhaust tumbler(s) individually to the outdoors. IMPORTANT: At no point may the cross sectional area of installed venting be less than the cross sectional area of the exhaust outlet of the tumbler.

Gas Requirements The following must be furnished and installed by the customer for the gas service line to each tumbler. Refer to Figure 12. WARNING To reduce the risk of fire or explosion, DO NOT CONNECT THE GAS LINE TO THE TUMBLER IF THE GAS SERVICE IS NOT THE SAME AS THAT SPECIFIED ON THE TUMBLER SERIAL PLATE! It will first be necessary to convert the gas burner orifice and gas valve. Appropriate conversion kits are available.
Gas Requirements WARNING 3 2 1 4 Check all pipe connections, internal and external, for gas leaks using a noncorrosive leak detection fluid. To reduce the risk of explosion or fire, DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS!

Electrical Requirements To Connect Electrical Service to the Tumbler NOTE: The wiring diagram is located in the junction or contactor box. 2 3 1 SE US FU E FUSE 1. Install a circuit breaker as close to the tumbler as possible. If more than one tumbler is being installed, a disconnect switch or circuit breaker should be provided for each. This will make it possible to disconnect each tumbler for maintenance purposes.
Electrical Requirements Jumper Configuration Instructions Changing the transformer configuration jumper is required, PRIOR TO SUPPLYING POWER TO THE MACHINE, if any of the following apply: IMPORTANT: Failure to install the proper configuration jumper may result in damage to sensitive electronic controls and may void warranty. ● You have 200 – 208 Volt service and are connecting a model rated for 240 Volt operation.
Electrical Requirements Electrical Requirements Refer to Table 9. NOTE: Minimum wire sizes are obtained from Canadian Electrical Code and are intended for use as a guideline only. Electrical connections should be made only by a qualified electrical contractor in accordance with all applicable local and national requirements. NOTE: Electrical specifications below are subject to change without notice. Always refer to product serial plate for most current specifications of product being installed.
Steam Requirements NOTE: Machines require a constant 80 to 100 psig (5.62 to 7.03 kg/sq cm) steam service for optimum operation. The maximum allowable steam pressure for use with 60 Hertz or 50 Hertz tumblers is 125 psig (8.6 bar). In no case may the pressure exceed the above value. Obtain specific steam service pipe sizes from steam system supplier or a qualified steam fitter. ● Refer to Figure 17 and Figure 18 for proper steam pipe configurations.
Steam Requirements Installing Steam Trap and Making Condensate Return Connections The steam trap must be installed and the coil outlet connections must be connected to the condensate return lines. The following steps outline the procedure for installing the steam trap and connecting the condensate return lines. Refer to Figure 17 and Figure 18 for typical installations. 1. Use flexible lines between steam inlet solenoid and steam coils, as well as outlet between steam coil and traps.

Adjustments 5. After air shutter is adjusted for proper flame, tighten air shutter adjusting screw securely. WARNING To reduce the risk of electric shock, fire, explosion, serious injury or death: • Disconnect electric power to the tumbler before servicing. • Close gas shut-off valve to gas tumbler before servicing. • Close steam valve to steam tumbler before servicing. • Never start the tumbler with any guards/ panels removed.
Adjustments Airflow Switch To adjust, open door, loosen jam nut and turn door strike screw in or out as required. Retighten jam nut. The airflow switch is set at the factory for proper operation. No adjustment necessary. Refer to Figure 20. IMPORTANT: The airflow switch vane must remain closed during operation for the heating system to run. If the air flow switch vane opens and closes during the drying cycle, this indicates insufficient air flow through the tumbler.
Adjustments Belt Drive The drive assemblies consist of motors, belts, eyebolts and a step pulley. The pulley diameters are sized to produce a cylinder speed of 37-39 RPM for 120 pound models or 29-31 RPM for 170 pound models. The step pulley assembly is used for speed reduction as well as a means of adjusting belt tension. The pulley mounting plate is attached to the cabinet.
Removing Tumbler from Service If the tumbler is to be removed from service, perform the following steps where applicable: ● Turn off electrical supply external to machine. ● Turn off electrical disconnect on machine. ● Turn off gas supply external to machine. ● Turn off manual gas shut-off valve on the machine. ● Turn off steam supply external to machine. ● Remove all electric, gas and steam connections.
