10 210 510H Dometic® Gravity-Discharge Toilets INSTRUCTION MANUAL WARNING IMPORTANT NOTICE Dometic® toilet systems must be installed according to Dometic’s recommended procedures. This manual must be read and understood before adjustment, maintenance, or service is performed. Modification of this product can result in property damage.
Important Information Before Operation 1. Do not use chlorine or caustic chemicals, such as laundry bleach or drain-opening types, in the system. These products damage the seals in toilets and dump valves. 2. Do not permit foreign objects (paper towels, paper cups, diapers, sanitary napkins, etc.) to be flushed through the toilet. 3. Mechanical seal toilets, like Dometic units, are designed to only discharge directly into a holding tank.
Installation 1. To replace an older toilet, turn off water supply to toilet. Disconnect water line at toilet water valve. Unscrew floor bolt nuts and remove toilet. Discard old floor seal and mounting bolts. The old floor flange may be used if it is in good condition and fastener holes are positioned as shown in Figure A. Make sure center of floor flange is at least 11 inches from back wall (Figure A). 2.
Cleaning For routine cleaning, use SeaLand® Toilet Bowl Cleaner. If this cleaner cannot be found in your area, contact Dometic for your nearest dealer. If the cleaner is not available, use most any non-abrasive bathroom and toilet bowl cleaner. Please follow label instructions. Fig. A FLUSH BALL CLEANING: After a period of time, mineral deposits from hard water may build up on the flush ball or seal, resulting in a slow water leak. To prevent this, periodically clean the flush ball and seal. 1.
Drain Water from Toilet 1. Turn off water supply to toilet. 2. Remove water supply line from water valve. 3. Place a small container under water valve inlet to catch draining water. 4. Press flush pedal and allow water to completely drain from water valve and vacuum breaker. 5. Leave water line disconnected until threat of freezing temperature is past.
