D. FRESH AIR SUPPLY REQUIREMENTS The EURO-35 air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An unrestricted source of air is necessary for each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square meters) is required for each dryer. If registers or louvers are installed over the openings, then the area must be increased.
E. EXHAUST REQUIREMENTS Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure which results in slow drying, increased use of energy, and shutdown of the burner by the airflow (sail) switch, burner hi-limit, or lint chamber hi-heat protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside. CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.
SINGLE DRYER VENTING IMPORTANT: For exhaust duct runs up to 20 feet (6.1 meters), a minimum size of 10-inches (25.4 cm) must be used. HORIZONTAL VENTING When a single 10-inch (25.4 cm) horizontal vent is used, the ductwork to the outlet cannot exceed 20 feet (6.1 meters) refer to Illus. A below. This calculation of 20 feet (6.1 meters) compensates or allows for the use of a maximum of only one (1) elbow (which is the outside outlet protection). Illus.
VERTICAL VENTING When vertical single 12-inch (30.48 cm) venting is used, the ductwork from the dryer to the outside outlet cannot exceed 25 feet (7.6 meters) refer to Illus. B below. This calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the 180° (turned downward) outside outlet. Illus.
MULTIPLE DRYER (COMMON) VENTING If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled into a common main duct. Each dryer is provided with a back draft damper. The individual ducts should enter the bottom or side of the main duct at an angle not more than 45° in the direction of the airflow. The main common duct may be any shape so long as the minimum cross-sectional area is provided.

H. STEAM INFORMATION It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the steam plumbing installation is adequate and conforms with local and national regulations or codes. Care must be exercised when leveling steam dryers into final position. After leveling the dryer, check the downward pitch of the heat exchanger from front to rear with a level. Likewise, check the downward pitch of the return condensate manifold toward its outlet part.
a. The pressure of the condensate in the steam supply will cause water hammer and subsequent heat exchanger (steam coil) failure. The steam supply connection into the main supply line must be made with a minimum 10-inch (25.4 cm) riser. This will prevent any condensate from draining towards the dryer. b. The steam supply piping to the dryer must include a 12-inch (30.48 cm) rise along with a drip trap and check valve. This will prevent any condensate from entering the steam coil. c.
4. Steam Damper Air System Connections The EURO-35 is manufactured with a pneumatic (piston) damper system which requires an external supply of compressed air. The air connection is made to the steam damper solenoid valve which is located at the rear inner top area of the dryer just in front of the electric service relay box. a. Air Requirements There is no air requirement for dryers with the Electromechanical Steam Damper Option.
5. Steam Damper System Operation The steam damper, as shown in the illustration below, allows the coil to stay constantly charged eliminating repeated expansion and contraction. When the damper is opened (Diagram 1), the air immediately passes through the already hot coil, providing instant heat to start the drying process. When the damper is closed, ambient air is drawn directly into the basket (tumbler), allowing a rapid cool down (Diagram 2).
6. Steam Damper Air Piston (Flow Control) Operation Adjustment Damper operation was tested and adjusted prior to shipping at 80 PSI (5.52 bars). If damper air adjustment is necessary, locate the flow control valve and make the necessary adjustments as noted below.
I. PREPARATION FOR OPERATION/START-UP The following items should be checked before attempting to operate the dryer: 1. Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer. 2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label affixed to either the back side of the upper control door or left side panel/wall area behind the control door. In the case of 208 VAC or 230/240 VAC, THE SUPPLY VOLTAGE MUST MATCH THE ELECTRIC SERVICE EXACTLY. 3.
J. PREOPERATIONAL TESTS ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions. 1. Turn on electric power to the dryer. 2. Refer to the Operating Instructions for starting your particular model dryer. 3. GAS MODELS ONLY a.
5. Make a complete operational check of ALL operating controls. NOTE: If computer program changes are required, refer to the computer programming section of the manual supplied with the dryer. 6.
