Special Notes Note: Highlight areas requiring special attention or clarification. Caution: Indicates that personal injury or damage to equipment may occur unless specific guidelines are followed. Warning: Indicates that serious or fatal injury may result if specific guidelines are not followed. 2 Heater Warnings Warning To Installer: Correct installation of this heater is necessary to ensure safe and proper operation. [. . . ] To prevent asphyxiation, the heater must not be operated in enclosed areas. 4. Temperature Control · The temperature is monitored constantly at the heater intake or thermostat. · This temperature is compared to the set temperature on the adjusting dial. · The heater cycles through Boost, High, Medium and Low heat modes to maintain the desired temperature. · If the desired temperature is exceeded while the heater is operating in low heat mode the heater will switch off. · The heater will re-start in medium heat mode once heat is again required. 1 Switch On · Switch the heater on using the room thermostat's, On/Off switch (1=On, 0=Off ) or the rheostat switch. 2 Start Up On start up the indicator light illuminates and the following sequences take place: · Control unit does a systems check (glow plug, flame sensor, temperature sensor, safety thermal sensor). · Glow plug is energized and starts preheating the combustion chamber. · After a short delay (approximately 15 seconds) the fuel pump delivers fuel. · Ignition will take place as the fuel/air mixture contact the glow plug. 6 5 Switch Off Once switched off either manually or automatically, the heater begins a controlled cool down cycle. · The blower continues to run for 3 minutes and automatically switches off. Controls and Safety Equipment · If the heater fails to ignite within two 90 second start attempts, a "no start" shut down occurs. · If a flame out occurs after the heater has started, the heater will attempt to restart. · If repeated flame outs occur within 10 minutes the heater will not restart. · Overheat shut down will occur if there is a restriction of the heating air flow (i. e. The overheat switch will automatically reset once the heater has cooled down. Once the air flow restriction is removed, the heater can be re-started by switching the heater off then back on. · If the voltage drops below 10. 5 volts or rises above 15. 9 volts the heater will shut down (21volts and 30 volts for 24 volt systems). · If the glow plug circuit or fuel metering pump circuit are interrupted the heater will not start. 3 Temperature Setting Using the adjusting dial, set the desired temperature range. 30°C (85°F) Operation indicating light Low High · The blower motor is checked on start up and every 4 minutes. Shut down will occur if the blower does not start or maintain proper speed. 14 Operational Flow Chart 15 Wiring Diagram D1LCcompact Models: 25 1976 05 (12v) 25 1977 05 (24v) 16 Wiring Diagram D1LCcompact Models: 25 1965 05 (12v) 25 1966 05 (24v) 17 Wiring Diagram D1LCcompact Models: 25 1895 05 (12v) 25 1896 05 (24v) 18 Maintenance, Troubleshooting and Repairs Recommended Periodic Maintenance · Remove the glow plug and inspect for carbon build up. If cleaning is required, use brass brush (Espar part number CA0 05 003). Espar recommends the use of non detergent 100% volatile carburetor cleaner and an air gun will also help. [. . . ] · Hold the fuel line in the measuring glass while fuel is being delivered. · The pump will stop automatically after delivering fuel for 90 seconds. · If the fuel quantity is outside this range, check for and remove any restriction in fuel system or replace the fuel metering pump. (Check screen in suction side of pump) Note: The fuel quantity is not affected by voltage variances.
