years.
This manual describes the operation of the Neco Series
One Centrifugal Heater. It is designed for low to medium
temperature grain conditioning, and is ideal for the aeration
of rice, popcorn or other select grains.
It is available in both propane vapor and natural gas
models.
The principal concern of Neco is your safety and the
safety of others associated with grain handling equipment.

FUEL CONNECTION
Important! Do not use propane tanks which have previously
been used for ammonia unless they have been purged according to procedures of the National L. P. Association.
Be sure fuel supply system complies with all local codes
for L. P. gas installations.
LIQUID PROP ANE
MODELS
1. LP models are designed to run on liquid propane, with
liquid draw from the propane tank.A void using propane supply tanks that have been used for vapor
draw for long periods of time. When using liquid draw
systems any moisture that may be present in tank or
lines may freeze when system is used in cold weather.
T o avoid this, the usual precaution is to purge the
system with methanol.
2. Run proper size line (see specifications) to liquid pipe
train on heater. Have a qualified gas service man
inspect installation to be sure that everything is installed according to local codes and ordinances.
3. After installation is complete check all connections
for leaks with liquid detergent or comparable. Wear
rubber gloves and eye protection. Avoid contact
with liquid propane. DO NOT USE FLAME FOR
LEAK TESTING.
PROP ANE VAPOR MODELS
2. Run proper size line (see specifications) to pipe train
on heater. Have a qualified gas service person in
spect installation to be sure everything iinstalled according to local codes and ordinances.
3. After installation is complete check all connections
for leaks. DO NOT USE FLAME FOR LEAK
TESTING. (see above for other precautions.)
NATURAL GAS MODELS
1. Natural gas models are similar to vapor models, but
have a larger orifice to accommodate lower pres
sure sometimes found with natural gas.
2. Run proper size line (see specifications) to pipe train
on heater. Have a qualified gas service
man inspect installation to be sure everything is in
stalled according to local codes and ordinances.
3. After installation is complete check all connections
for leaks. DO NOT USE FLAME FOR LEAK
TESTING. (See above for other precautions.)
1. Propane vapor models are designed to run directly
off of supply tank or from a separate external vapor1izer .

Transformer and Wiring Voltage DropPower Supply
An adequate power supply and proper wiring are
important factors for maximum performance and long
life of the dryer . Electrical service must be adequate
enough to prevent low voltage damage to motors and
control circuits. In 220V 1 ph and 220V 3 ph systems
a separate neutral wire is required for the 120V
heater circuit, and should be connected to terminal
#1 in the master heater . Do not run in conduit with
motor power lines.
Machine To Earth Grounding
It is very important that a Machine T o Earth ground
be installed at the worksite. The complete unit must be
wired and grounded to all local applicable codes. The
proper grounding will provide safty to the operators and
ensure long life to all circuit boards.
It is necessary to know the distance from the unit to
the available transformer, and the horsepower of your
fan unit. Advise the service representative of your local
power supplier that an additional load will be placed on
the line. Each fan motor should be wired through a fused
or circuit breaker disconnect switch. Check the KVA
rating of the transformers, considering horsepower and
load. The power supply wiring , main switch equipment
and transformers must provide adequate motor starting and operating voltage. Voltage drop during startup
should not exceed 14% of normal voltage, and after
motor is running at full speed it should be within 8% of
normal voltage. Check Electrical Load Information for
HP ratings and maximum amp loads to properly size
wire and fusing elements. Standard electrical safty practices and codes should be used. (Refer to National Electrical Code)
