Maintenance operations Over time, you will develop a build up of lime and calcium inside the heating coil which will greatly reduce the efficiency of the heater. To clean the inside of the heating coil, follow these instructions: 1. Add 2 gallons of clean water into the solution tank. 2. Add 1 quart of a deliming chemical into the solution tank. 3. Do not turn the heater on for this process 4. Re-circulate the water and deliming chemical in the solution for approximately 30 minutes, or until the chemical stops reacting with the lime. (Use the same process as pre-heating the water in the solution tank) 5. Empty the solution tank and refill with clean water 6. Spray the clean water out of the solution tank into a drain or bucket. This will clean out the pump, water lines and heating coil. NaceCare Solutions 1205 Britannia Road East Mississauga, Ontario, Canada L4W 1C7 Toll Free: 1 800 387 3210 Toll Free Fax: 1 800 709 2896 8
