Installation Procedure

3.1

Components supplied by owner

Some plumbing and electric components are to be supplied by owner. These components are listed below:
a) 3/4" or 1" inlet valve with terminal (A2, drawing 1);
b) Tank for produced water (P). The tank should have a safety overflow valve (V1);
c) 3/4" female thread discharge to the sea. A discharge fitting of 3/4 female (Y) is supplied by Tecnicomar where lines
BRINE (R) and UNSAFE WATER (S) are connected (refer to drawing 1);
In case of installation aboard a vessel, the discharge must be installed above the water line.
d) power supply line, protected by an automatic all-pole thermal and differential protection/ disconnection device. The
differential circuit breaker must be set to act with the dissipation current of 30 mA. For setting of the thermal circuit
breaker and for the sizing of the power supply line the values from the POWER REQUIREMENT TABLE should
be respected (ref. Section 9).
3.2

Plumbing connections

CONSIDERATIONS:
 Lenght of connection lines: the watermaker will work most efficientely with short plumbing connections. When the
suction line is long the feed pressure decreases. When the discharge line is long the back pressure increases in that
line. There should be no back pressure on the discharge line or on the product line.
 Feed water: be sure that the inlet thru-hull fitting is installed in a way that the watermaker receives an uninterrupted
supply of air-free feed water.
 Membranes: the membrane vessels must not be exposed to temperature higher than 50°C (122°F) or lower than 5°C
(41°F). For preservation of membrane modules in very cold areas see par. 6.3
For correct installation of SAILOR in compact and modular version:
 Connect the SEA WATER INLET (A2) with the T1 side of the manual three-way valve (T) using the supplied hose
of dia. 20 mm.
 Connect the outlet of the low pressure pump (A) with the inlet of the prefilters (B).
 Connect the Auto-Flushing system (if supplied) to the tee fitting on the prefilters.
 Connect the BRINE (R) and UNSFE WATER (S) lines to the discharge connector (Y).
 Install the supplied fresh water fitting (V) onto the fresh water tank (P). Connect outlet of three-way solenoid valve
(U line) to the fresh water fitting (V). Be sure that fresh water tank has an overflow valve (V1).
For correct installation of SAILOR in splitted (slim) version (control panel, membranes module, low pressure pump
and prefilters):
 Connect the SEA WATER INLET (A2) with the T1 side of the manual three-way valve (T) on the low pressure
pump using the supplied hose of dia. 20 mm.
 Connect the outlet of the low pressure pump (A) with the inlet of the prefilters (B).
 Connect the Auto-Flushing system (if supplied) to the tee fitting on the prefilters.
 Connect outlet of prefilter (C) to inlet of the high pressure pump (F) and to the low pressure gauge (D).
 Connect the outlet of the high pressure pump (F) to the first membrane.
 Connect the dischrge from membranes to the pressure regulation valve (I) located behind the control panel.
 Connect the produced water from mebranes to the flowmeter (L)
 Connect the BRINE (R) and UNSFE WATER (S) lines to the discharge connector (Y).
 Install the supplied fresh water fitting (V) onto the fresh water tank (P). Connect outlet of three-way solenoid valve
(U line) to the fresh water fitting (V). Be sure that fresh water tank has an overflow valve (V1).
Be sure to tighten well gaskets and fittings to avoid air infiltration or water leaks.
