Johnson Hardware IB-412 R01 Installation Instructions, Safety, Introduction, Location, Mounting

6. SAFETY:

Ensure that these instructions reach the owner, the skipper or the operator of the craft, as it contains important safety information ON COMPLETION OF Installation:

SHUT THE FLUSH CONTROL CLOSE BOTH SEACOCKS

INSTALLATION INSTRUCTIONS

Introduction:

If the installation of the toilet results in being connected to any through-hull fitting that may possibly be below the waterline whether when the craft is at rest, underway, heeling, rolling or pitching, you must install the toilet in accordance with the present installation instructions.

Failure to follow such instructions may cause water to flood in, which may result in loss of life.

ACCIDENTAL DAMAGE

If the toilet is connected to any through-hull fitting and if the toilet or the pipework are damaged, water may flood in, causing the craft to sink with a consequent possible loss of life. For this reason, if you are making connections between the toilet and any through­hull fitting that may be possibly situated below the waterline, fullbore seacocks must be fitted to such hull-fittings, to allow them to be shut off.

The seacocks must also be positioned where they are easily acces- sible to all users of the toilet.

If, for any reason, it is not possible to do it, then secondary full-bore marine quality valves must be fitted to the hoses where they are easily accessible

Caution:

USE SEACOCKS! USE LEVER OPERATED, FULL-BORE MARINE SEACOCKS AND VALVES. THE USE OF SCREW-DOWN GATE VALVES IS NOT RECOMMENDED.

PIPEWORK LOOSING

All pipeworks must be fastened both in the gate side and in the remaining ones with a stainless steel hose clamp. Please keep in mind that an eventual leak might cause the craft to sink, with consequent loss of life USE HOSE CLAMPS!

BOWL RIM BELOW THE WATERLINE:

If the toilet is connected to any through-hull fitting and if the rim of the bowl falls below the waterline, water may flood in, causing the craft to sink, which may result in loss of life. Therefore, if the rim of the toilet is less than 20 cm (8”) above the waterline when the craft is at rest, or if there is any possibility that the rim of the bowl may be below the waterline at any time, a vented loop must be fitted in any pipework connected to a through-hull fitting, irrespective of whether inlet or outlet.

USE VENTED LOOPS!

Special notes: The smaller bore inlet pipework is more dangerous than the larger outlet one. Unless there is a ventilated anti-siphon loop in the inlet pipework, water will flow into the bowl whenever both the inlet seacock is opened and the rim of the bowl is below the actual waterline.

Although moving the flush control lever to the “Shut” position will restrict the flow, this lever cannot be relied upon as a safety device. To make a loop in the hose without mounting a vent may be as hazardous as no loop at all, because water will siphon over the loop.

IN FACT, IT IS THE VENT THAT ACTUALLY PREVENTS THE SIPHON

1. LOCATION

The toilets base and pump is supplied assembled for a right handed operation. If you wish, both comfort and compact bowl models may be reassembled with the pump positioned on the left hand side.

The bowl and the base/pump unit are not assembled. If you want to change the pump mounting from right to left hand, do so before installing the toilet.

Change to left hand operation

1.Pull off the hose that runs from the pump to the bowl.

2.Remove the 4 screws that secure the pump assembly to the base.

3.Lift off the pump assembly and leave the base valve gasket on its 3 locating pegs.

4.Remove the 4 bolts that secure the bowl to the base.

5.Rotate the bowl 180° and re-secure it, using the nylon washers to protect the ceramic from the stainless steel washers and nuts.

6.Rotate the pump assembly 180° and re-secure it.

7.Rotate the push-fit intake elbow 180° and refit the hose between the pump and the bowl.

Assemble the bowl on the top of the base, using the attached bolts, washers and gaskets. The nylon washers are to protect the ceramic from the stainless steel washers and nuts.

•choose a location which will give enough clearance all around and above the toilet Ensure that there is room to operate the pump and that there is access to the drain plug at the end of the base.

•the mounting surface must be flat, rigid, and strong enough to support a man’s weight and should be at least 50 mm (2”) wider and 50 mm (2”) deeper than the base of the toilet.

•you will need sufficient clearance below the mounting surface to be able to secure the mounting bolts

•the seat and the lid should be able to swing open at least 110 degrees, in order they will not fall forward when the craft heels or pitches. When they are swung open, they must be supported so that the hinges are not strained.

2. MOUNTING:

You need

•Stainless steel bolts: 4 pcs, 8mm (5/16”) diameter of length to suit the thickness of the mounting surface.

•Stainless steel nuts: 4 pcs preferably self-locking. If you do not use self-locking nuts you need to add locking compound on the screws / nuts.

•Stainless steel washers: 8 pcs, large diameter, but not more than 21 mm (13/16”) diameter.
