toilet Dimensions Dimensions may vary ±3/8-inch (13mm). Toilet INSTALLATION INSTRUCTIONS System Requirements: • 2 GPM (10.6 lpm) or larger water pump. • 1/2-inch (12.7 mm) water line terminating in 1/2-inch MPT fitting (to connect to toilet water supply hose). • 4-bolt floor (closet) flange. SeaLand flanges available include 3-inch spigot, socket, MPT, or 45-degree swivel socket. • 12 VDC through 7- or 8-amp fuse or circuit breaker. Use 14-gauge stranded copper wire.
STEP 5a: For through-the-floor water line and electrical wires, mark another centerline 6 inches (152 mm) from the back wall (fig. 4). Below-Floor Installation Fig. 4 STEP 5b: For through-the-wall water line and electrical wires, mark a centerline 8 inches (203 mm) up from the floor centerline (fig. 5). Above-Floor Installation Fig.
IMPORTANT: If replacing an existing toilet that uses a 2-bolt floor flange, drill two 5/16-inch dia. holes in old floor flange that align with two additional holes in floor flange adapter. Use two #10 or 12 x 1-1/2-inch wood screws and washers for these drilled holes, and two T-bolts with flat washers and nuts to fasten flange gasket and floor flange adapter to old floor flange. Do not use old hardware or seal.
STEP 19: Set the toilet in place (fig. 19) and secure to floor with the #14x2-1/2 inch long lag bolts (fig. 20). Install decorative bolt caps by pushing them onto bolt heads (fig. 21). STEP 16: With toilet close to floor flange, connect flexible water supply hose to the water line fitting (fig. 17). Fig. 17 STEP 17: Insert the positive (+) 12 VDC wire into position 1 of the green terminal block and tighten the screw securely.
Model 3400 Remote flush switch INSTALLATION 3400 series toilets feature a remote flush switch to control the “Flush” and “Add Water” functions. Follow the instructions below for switch installation. STEP 1: Select a location for the switch. 8 feet of cable (2.4 m) is provided. You may need to supply more wire, depending on how far you locate the switch from the toilet. STEP 2: Cut an opening 1-1/4” wide x 1-5/8” high (see diagram at right).
Important Information Before Operation 1. Fill freshwater tank and add deodorant to holding tank through toilet bowl. 2. Make sure all guests understand the operation of the toilet system. 3300 models: Follow instructions below. 3400 models: "Add Water" and "Flush" are clearly marked on the remote switch. See more information below. 3. Shut off the toilet system before servicing and do not leave the vehicle with toilet system circuit breaker on. 4. Never use drain openers, alcohol, solvents, etc.
OPERATING INSTRUCTIONS 1. Adding More Water To Toilet Bowl Pull up the flush handle (3300 model) or push "Add Water" switch (3400 model) until the desired water level is attained. To prevent overflowing the toilet, a timer inside the control module limits the amount of water that can be added. 2. Flushing The Toilet Push the flush handle down (3300 model) or push "Flush" switch (3400 model) for a moment, then release it.
Proper Cleaning – Toilet Bowl and Seal The SeaLand toilet should be cleaned regularly for maximum sanitation and operational efficiency. You can clean it just as you would a household toilet. Do not use caustic chemicals, such as drain-opening types, as they will damage the seals. BOWL CLEANING: For stubborn stains, use SeaLand Toilet Bowl Cleaner (Fig. A). It’s manufactured especially for use with SeaLand toilets. In certain locations where water is hard, a build-up of lime may dull the toilet bowl finish.
Winterizing At the end of each traveling season, the SeaLand toilet system must be winterized for storage. The following procedure should be used: 1. Pump out waste holding tank. 2. Thoroughly flush toilet system with fresh water. 3. Drain freshwater tank. 4. Add freshwater antifreeze to freshwater tank. 5. Flush freshwater antifreeze and water mixture through toilet and into the waste holding tank. Each installation is different so amounts may vary.
Flush Mechanism Components 3. Lift ceramic toilet straight up from base and set it down just in front of floor flange. Turn off water to toilet and disconnect flexible water line. Disconnect power wires and/or flush switch wires if necessary. 1. To access base assembly components, remove decorative screw caps and unscrew two bolts that hold ceramic toilet to floor. 2. Remove access cover from top of ceramic and set it aside.
