Page 37: Periodic Lnspection
For blockage at the Check drain pipe discharge. (Ex. EN18WI30LS) Periodic Maintenance Equipment Wipe the outside surface with a wet cloth, then dry the surface. Use a neutral detergent to clean any stains. If an external condensate neutralizer is installed, periodic replacement of the neutralizing agent will be required. - Page 38 Periodic Maintenance Water Drain Valve (with Water Filter) If the water drain valve (with water filter) is covered with debris, the hot water may not run smoothly, or the unit may put out cold water. Check and clean the filter as explained below. * To avoid burns, wait until the equipment cools down before draining the water.
- Page 39 Periodic Maintenance If the unit becomes saturated with lime or scale build-up, the hot water may not run smoothly, or the unit may put out cold water. In addition, damage can occur resulting in failure of the unit if lime or scale deposits are left untreated within the unit.

Page 40: Changing Default Temperature Setting
Changing Default Temperature Setting * The water heater has been factory set to allow a maximum temperature setting of 120 °F (50 °C). To access higher temperature settings through the remote controller, follow the below steps. <When setting the maximum temperature to 130-140 °F (55-60 °C)> 1. - Page 41 If there remains a freezing risk, contact the nearest Electrolux agent. Take the measures below for extremely cold temperatures*. Outside temperature including wind chill factor less than -30°F (-35°C) for EN18WI30LS, EP18WI30LS EN19WI30LS, EP19WI30LS - When supplying combustion air from the indoors, the room temperature must be greater than 32°F (0°C) to prevent freezing and the room inside must not have negative pressure.
- Page 42 <EN18WI30LS, EP18WI30LS, EN19WI30LS, EP19WI30LS> If the water heater will not be used for a long period of time, Drain the water. Drain the water as follows: CAUTION To avoid burns, wait until the equipment cools down before draining the water.

Page 43: Installation Check
9. Installation Check Installation problems can cause the unit to work unsatisfactorily. If the unit is not working properly, but there are no error codes or evidence of malfunction, check the installation. * Installation Checks: Altitude 1. If this water heater is installed in a location where the altitude is greater than 2000 ft., the combustion may become abnormal because of the thinness of the air. -
