SAFETY PRECAUTIONS
1. ALWAYS follow safety precautions and
COAST GUARD recommendations! Your safety and the safety of your crew
take priority over all else!
2. The NACC unit was specially designed to
be versatile and can be coupled with or used separately with most
seafood holding containers and holding systems. In either
circumstance, both should be fastened securely to the ship, either
on the deck or against a bulkhead. We recommend that you mount your
NACC unit directly onto your bin if possible. This can be
accomplished by following the simple steps as described in annex “A”
and will eliminate two external water hoses that could be a safety
hazard to you and your crew.
3. Always install and fasten water lines,
hydraulic lines and electrical wiring in accordance with safety
regulations and assure yourself that they will not become a safety
hazard. We recommend that you retain the services of professionals
for these installations if you are not qualified.
4. NACC recommends that you fit your bin
with a large diameter emergency drain valve at the bottom to quickly
empty the bin of water in extreme weather conditions. This will help
to lower your vessel’s center of gravity and help to stabilize your
ship.
5.
Always use approved materials and
components and follow all safety regulations in accordance with
local, state/provincial, and federal laws and recommendations.
6. CAUTION! This unit contains
hazardous moving parts. Always cut hydraulic and electrical power
before attempting to remove front cover or servicing unit.
A10HVWC Model
INSTALLATION INSTRUCTIONS
There are four
water connections, two hydraulic connections and one electrical
connector on the unit.
You can refer to
Fig. 1 as a general piping layout guide.
Fig. 1
The seawater inlet
and outlet connections are to provide cooling water to the unit.
These connections are located at the bottom of the right side of the
unit if you are facing the front. Both are standard ¾” NPT. The
inlet should be connected to a source of seawater via a through-hull
fitting containing no copper or copper containing alloy and should
be located at a point in the hull that will assure a continuous
source of new seawater. If more than 20’ of hose is needed, we
recommend that you use a 1” hose. The discharge water can be routed
back to the sea either above or below the waterline but it is
preferable to keep the conduit as free as possible of restrictions
and back pressure. It is therefore advisable to locate the discharge
point above the waterline. These water connections and conduits must
remain completely independent of all other hoses or connections.
(Fig. 3)
The bin water connections are to
re-circulate the bin water through the unit and bin. These
connections are located alone on the bottom of the left side of the
unit if you are facing the front. Both of these are standard
¾” NPT. (Fig. 2)
 Fig. 2
The “out” water
connection on the unit must be piped to the upper access hole on
your bin either with a separate hose or through the back of the unit
and directly into the bin through a user drilled hole in the back of
the unit should you mount your unit directly to the bin. You can
also simply remove the units back cover to facilitate this process.
Simply connect the “out to tub” water hose to the top hole in the
tub. The “supply” water going into the tub should be sprayed onto
the surface of the tub water. This will assure an adequate
oxygenation of the tub water and will also help eliminate ammonia
buildup.
The “in” water
connector on the unit should be piped to the lowest hole in the bin.
This can be done either through the use of a separate hose or
directly through the back of the unit in the same fashion as the
“out” connection.
Note that the water
hoses between the unit and tub should be insulated.
You should install
an appropriate stainless steel or plastic strainer inside the tub in
order to avoid the intake of contaminants such as pieces of debris
or shell that could damage the unit’s water pump.
Seawater must be
allowed to drain freely through a hose, unrestrained, back to the
sea through an overflow located at the top of the bin. This
overflow drainage port should be located about 2 to 4 inches below
the water bin supply port. If your bin does not have an overflow
hole, you must install one. This can be easily accomplished using a
standard plastic through-hull fitting. Your NACC unit takes up a
predetermined amount of new seawater that it routes to the bin and
the excess water will overflow. If you do not have an overflow hole
and piping installation, this water will pour out onto the deck from
the top of your bin
NOTE THAT ALL
HOSES, PIPING AND FITTINGS USED IN THIS INSTALLATION MUST BE MADE OF
PLASTIC OR OTHER NON COPPER OR COPPER CONTAINING MATERIAL. ANY
COPPER IN CONTACT EITHER DIRECTLY OR INDIRECTLY WITH THE WATER IN
THE BIN COULD HARM OR KILL YOUR CATCH
We recommend that
you use wire hose (non-collapsing) for all water conduit
applications.
Your NACC unit does not
require water filters in most applications. This eliminates the cost
and trouble of replacing clogged filters.
The electrical
supply should be wired with 14-gauge, automotive type multi-strand
wire and should be protected by a fuse of no more than 10-amp
capacity. 12V DC power must be supplied to the connector located on
the right of the unit. (Fig.3)
 Fig.

Please note the polarity:
RED + /
YELLOW -
Because of the many
different types of sources of hydraulic power found on fishing
vessels, your unit is equipped with a pre-adjusted flow control that
will protect it from excessive operating speeds that could be
produced by your vessel’s hydraulic system. A special universal
adaptor kit is available and can be supplied by NACC. The unit
requires 9 gpm of hydraulic fluid at 1200 to 1500 psi. Your
hydraulic supply and return lines should be connected to the proper
inlets and outlets located on the bottom right side of the unit
above the unit cooling water ports. (Fig.3). You may have to adapt
your hydraulic system for this purpose if you do not use the
universal adaptor.
A greater flow rate or pressure could
damage your unit and could be a safety hazard. If you supply less
than 8 gpm, the unit’s performance will be
lower but it will still function. We strongly advise you to retain
the services of a qualified hydraulics
technician to complete this part of the installation. NACC can
assist you in acquiring certain components such as
pressure/flow controls, compensated pumps, oil coolers,
etc.
OPERATION
The operation of
your new NACC “Living Sea Systems” water treatment unit is
simplicity itself.
Just provide
hydraulic oil pressure (9 gpm at medium pressure) and turn the
electrical power switch “ON” after installation and having filled
your bin with clean seawater. (Fig. 4)
If the system is to
be used for particularly muddy or silty products such as mussels or
scallops, we recommend that you install an inline, pool type filter
on the bin return hose. (The hose that brings the water from the
bin to the unit.)
NOTE THAT TURNING
THE ELECTRICAL SWITCH “OFF” DOES NOT GUARANTY THE COMPLETE STOP THE
UNIT’S OPERATION. THIS WILL ONLY TURN OFF THE CONTROL SOLENOID FOR
THE HYDRAULIC SYSTEM AND THE CLUTCH ON THE REFRIGERATION COMPRESSOR.
HYDRAULIC PRESSURE MAY STILL BE PRESENT IN THE SYSTEM AND COULD
CAUSE THE UNIT TO FUNCTION THEREBY PRESENTING A POTENTIAL SAFETY
HAZARD. PLEASE ALSO NOTE THAT WHEN YOU TURN THE MACHINE “OFF” THE
HYDRAULIC OIL FLOW IS NORMALLY STOPPED. THIS MEANS THAT YOUR
HYDRAULIC SYSTEM MUST BE EQUIPPED WITH A PRESSURE RELIEF DEVICE.
There are three
indicator lights on the right upper side of the unit.
The first
green (left) light indicates
electrical power “ON” and is incorporated in the power switch.
The second
green (middle) light indicates the
refrigeration system is “ON”. This indicator will turn off when the
desired water temperature is reached. As the water warms again, the
light will activate again to indicate that the refrigeration is once
again in operation.
The third
red (right) light is a trouble light
and will come on if there is a problem with cooling system in the
unit. This light may flicker upon startup. You may disregard this
initial flickering. If this light activates at any time after, it
indicates a problem. Please call your local distributor if this
happens. (Fig.4)
 Fig. 4
The bin water
temperature has been preset at the factory at 40 degrees F. It has
been determined that this is the optimum temperature for preserving
live sea products of most types. Should you wish to raise or lower
the water temperature, this can be easily accomplished by adjusting
the water temperature thermostat located inside the unit and can be
accessed from the right side the unit. (Fig.4 and 5)
 Fig.
5
NOTE: NACC
units have a temperature range of 30 – 50 degrees F. We preset the
temperature at 40 degrees F.
NACC can
provide special units for water temperatures outside of these
parameters.
MAINTENANCE
Your NACC unit
requires very little maintenance. Simply check the drive belts for
wear twice per year and adjust as needed by loosening the 4
hydraulic motor mounting bracket bolts, raising the bracket until
the proper belt tension is reached and then tightening the bolts. DO
NOT OVER TENSION THE BELTS. YOU SHOULD LEAVE ½ INCH OF PLAY ON THE
BELTS. The belts are a standard automotive type and are readily
available. All other components are made of top quality materials
and will last for several years.
Occasionally, the
unit’s refrigeration condenser may need to be cleaned. We recommend
that you have this procedure done by a qualified refrigeration
technician
ALWAYS KEEP THE
UNIT UPRIGHT! IF YOU HAVE TO LAY IT DOWN, KEEP THE UNIT UPRIGHT FOR
48 HOURS BEFORE OPERATING IT AGAIN.
STORAGE
We recommend that
you flush the unit with fresh water before prolonged storage.
KEEP FROM
FREEZING!
If you store
your NACC unit in sub-freezing temperatures serious damage could
result.
Should you have to
store your unit in sub-freezing temperatures, the following
precautions must be taken:
1.
Run the unit for 30
seconds dry. (With the bin and seawater hoses disconnected).
2.
Disconnect the following
water hoses:
The four water hoses connected to the
water pump. (Fig.6)
 Fig.

Run the unit
again for 5 to 10 seconds to empty the water pump housing.
3. Disconnect the lower
chiller water conduit and drain chiller. (Fig. 7) You may have to
remove the chiller top cover in order to accomplish this.
 Fig.
