the seacock, then fasten the 90 degree thread to hose barb, with 5200 on to the ¾ inch nipple. The “closed end nipple” is the bronze threaded pipe open on either end.

The water strainer and pump can now be mounted, but first you must get each component fully assembled and ready to mount. The water strainer and pump brackets must be securely mounted on a flat surface. Do not mount on the sole of the boat (cabin floor). If a nearby bulkhead cannot accommodate the size of the mounting brackets, a mounting shelf or platform must be built. Typically the shelf will be made from 3/4 inch marine grade plywood which can be either fiberglassed or mechanically attached to the boats sole or superstructure. Never screw directly into the hull.

When attaching the mounting brackets to the superstructure or a fabricated mounting shelf, always make absolutely positive that the length of the screws being used to mount the bracket will not engage the hull. If there is any question as to whether the hull may be compromised, an alternative mounting method must be used or another mounting spot must be located.

The Water Strainer:

If you are using a Mermaid furnished water strainer, it will come with (2) 3/4 inch thread to hose barb hose fittings. Attach these fittings to the strainer using an ample amount of marine sealant on the threads. Again, if you are using a Mermaid strainer, locate the strainer mounting bracket. This is the bracket with a large hole in it. Unscrew the plastic bowl from the strainer body and place the strainer body in the hole. Replace the plastic bowl on the strainer body to lock the strainer in the bracket. This is meant to be a loose fit to facilitate cleaning when the strainer is dirty.

Water will flow from the sea cock through the strainer into the inlet of the pump. Ideally, the strainer and pump will be mounted so the water flow is at a slight upward grade to help eliminate air locks. Once you have settled on the mounting locations of the strainer and pump, attach each of their mounting brackets with (2) 1/2 inch s/s pan head screws. Note that the strainer is directional. Take notice of the stamped arrow on the top of the strainer when installing and insure the arrow is pointed toward the flow of water to the air conditioner unit

Ideally, the pump should be mounted with the external 5/8” water discharge (the line that goes TO the air conditioner) pointed vertically. However, there is an alternative position. The pump can be mounted with the external 5/8” water discharge on the side. To accomplish this successfully, it is IMPERATIVE to have the actual pump discharge at the highest level. In this position, the external 5/8” discharge will be located on the upper right corner of the pump with the ¾” intake facing you. In this alternative position, the pump will still operate as originally designed. Failure to follow either of these recommendations will void any warranty with the pump.
