Spectra Watermakers Newport 400 Installation Basics, Thru-hulls, Flow, Pipe Fitting Instruction

Installation Basics

•Read the directions!

•Avoid tight hose bends and excessive runs.

•Use heavy gauge wire.

•Install feed pump as low as possible.

•Use a dedicated thruhull with scoop type strainer.

Thru-hulls

Thruhull

Not Supplied.

Flow

It is mandatory that a dedicated 3/4” to 1” forward facing scoop type intake thru-hull and seacock be installed. Install the intake for the system close to the middle and as far below the water line as possible. Thru-hulls in the bow area are susceptible to air intake in rough conditions. Sharing a thru-hull with another system is not acceptable and will void the war- ranty. Sharing a thru-hull can introduce unforeseen problems such as intermittent flow re- striction, air bubbles, and contaminates. For racing boats and high speed power boats above 15 knots a retractable snorkel-type thru-hull fitting is preferred to be able to pick up water away from the hull.

Do not install the intake close to or downstream of a head discharge. Install as far below the waterline and as close to center line as possible to avoid contamination and air induction.

The brine discharge through-hull should be mounted above the waterline, in or just above the boot stripe to minimize water lift.

Double clamp all hose connections below the waterline.

Pipe Fitting Instruction

Plastic to plastic fittings should have 3 to 4 wraps of Teflon tape and will thread almost all the way in.

Avoid getting dirt or debris into the piping or hoses during assembly. A small bit of de- bris can stop the system! Avoid getting tape over the end of fittings that might get into the system. To insure this does not happen, leave the very first thread uncoated.

Avoid restrictions or long runs on the entire inlet side of the plumbing from the thru hull to the main feed pump module.

Prevent tight bends and excessive elbows. Any restrictions will hamper system performance. Secure the piping away from moving objects such as engine belts and hatches. Prevent chafe on the tubing as required. Test and inspect all piping and hose clamps after several hours of operation.

Wiring

•Pay attention to wire size or system performance will be impaired.

•Perform wiring to UL, ABYC, CE or applicable standards.
