DTD no. 22-5070 A-1 A Warning and Safety Instructions 1 General Information Service and repair work should only be carried out by a suitably qualified electrician (with specialist training, knowledge and eperience, and recent related work eperience) in accordance with all appropriate local and national safety regulations. Servicing, modification, testing and maintenance of electrical appliances should only be carried out in accordance with all appropriate legal requirements, accident prevention regulations and valid standards. Unless absolutely essential, e.g., fault finding with supply voltage, working on a machine connected to the power supply should always be avoided. If working on a machine with an applied voltage at a potentially dangerous level is unavoidable, special safety measures must be taken into consideration and complied with. Warning! Even with the machine switched off, power may be applied to some components. Before starting any service work, the machine must be disconnected from the power supply. Suitable measurements must be made to ensure that this is the case. A general visual check should always be carried out.
A-2 DTD no. 22-5070 2 Risk of Injury due to Sharp Edges and Protruding Parts Danger! There may be a risk of injury due to protruding parts. Protective goggles should be worn. There may be a risk of injury due to sharp edges. Protective gloves should be worn and the edge protection, mat. no. 05057680, should be used.

DTD no. 22-5070 A-3 3 Touch Current Measurement Note On machines with a ground connection, touch current leakage measurements should be carried out on all accessible conductive parts that are not connected to ground. Warning! Touch current measurement should only be carried out after the ground connection of the machine under test has been checked and found to be satisfactory! Dangerous voltages may eist on defective machines as well as on accessible conductive parts that are not connected to ground! Note Touch current measurement should be carried out on the following accessible conductive parts: Door handle Viewing screen with full metal front (stainless steel or aluminum/titanium) Viewing screen with metal trim (classic design)

DTD no. 22-5070 030-1 030 Technical Service Bulletins 4 Service 4.1 30-Inch Warming Drawers; Closing Behavior; Rep. Kit, Part #08349290 A ESW 4 warming drawers How to remedy drawer-closing issues. A The ESW 4 warming drawers have a closing device on the end of each telescopic runner. This Stop Control can become dislodged or damaged during handling, installation, or rough use. There is a repair kit that contains a pair of these drawer closure devices. A If indicated, please order part #08349290, Rep. Kit Pull-Out Spring Mechanism. The kit comes with an instruction sheet; you can download these instructions online. A Note that these closing devices have a left and right orientation; the springloaded hooks should be facing each other across the drawer. Remember also that these hooks need to be slid back and etended before installing and before closing the drawer. 4.2 ESW Warming Drawers; Fan Behavior A The newest models of warming drawers (ESW 4XX2) are electronically controlled. This allows for more precise temperature control and etended multi-function features. The timer function is one of these enhanced features. By selecting a timed cycle (1-4 hours), the unit will heat only for that amount of time. Once the timer has epired, the fan will continue to run. This is by design. Some customers may think that the timer is not working properly, but this is not the case. Reference page 13 of the owners manual. A There is no need to set up service for fan run-on. Eplain to the customer that the fan continues to run to prevent ecess heat buildup and to keep the warmth in the drawer even at all levels.
030-2 DTD no. 22-5070 4.3 ESW 4XX2 Warming Drawers A The timer feature on these electronically-controlled warming drawers does not function as described in the use and care manual.
