1.8 ADDITIONAL SAFETY REQUIREMENTS
1.9 Even when the motor is stopped, it should be con-
sidered “alive” as long as its controller is energized.
Keep hands away from the output shaft until the
motor has completely stopped, and the input power is
removed from the motor control panel.
1.10 Always use accurate test meters when checking elec-
trical components. Always work with another person
in case of an emergency.
1.11 STORAGE & HANDLING
1.12 When the Heat Transfer Package is received, make a
visual inspection of the unit, checking for any dam-
ages that may have occurred in shipment. The unit
should also be checked against the shipping list to
account for the un-mounted components which are
boxed and bound to the unit.
1.13 If any damages are found or parts missing, note this
on the delivery receipt and inform your B&G Factory
Representative at once. Care should be taken to pre-
vent damage due to dropping or jolting when moving
the unit. Transportation damage should be brought to
the carrier’s attention immediately upon receipt.
1.14 For long periods of storage, the unit should be
covered to prevent corrosion and contamination from
dirt. It should be STORED in a clean, dry location
between 0 – 170°F. The relative humidity should not
exceed 85%. The unit should be checked periodically
to ensure that no condensation has formed. After
storage, again check that it is dry before applying
power.
1.15 The unit is mounted on wooden skids which provide
for safe and easy movement to the installation site.
1.16 The final location should allow ample space for ser-
vicing all components of the unit. Be sure to allow
room for removal of the heat exchanger tube bundle,
should it be necessary.
1.17 The wooden skids should be removed and the base of
the frame leveled, grouted and bolted to the floor or
pad.
1.18 ELECTRICAL CONNECTIONS
1,19 The input voltage tolerance is +10/-10%.
1.20 All electronic equipment is susceptible to failure if
operated in ambient temperatures outside of its rat-
ing. The OPERATING temperature range for this unit
is 32 – 105°F. The relative humidity should not exceed
95% noncondensing. The unit should not be operated
outside these extremes.
1.21 GROUND CONNECTION
1.22 A grounding terminal is provided for a dedicated
ground wire connection. All provisions of the National
Electrical Code and local codes must be followed.
1.23 POWER WIRING
1.24 Power wire types and sizes must be selected based
upon conformance with the National Electrical Code
and all local codes and restrictions. In addition, only
copper (Cu) wire related for at least 75°C may be used
for the power connections. Refer to the input current
as listed on the motor nameplate when sizing wire.
WARNING: Prevent electrical shocks. Disconnect
the power supply before beginning installation.
Failure to follow these instructions could result in seri-
ous personal injury, death, and/or property damage.
WARNING: Electrical shock hazard. Inspect all
electrical connections prior to powering the unit.

cian in accordance with all applicable codes, ordinances,
and good practices. Failure to follow these instructions
could result in serious personal injury, death, and/or
property damage.

safety hazards. Failure to follow these instructions could
result in serious personal injury, death, and/or property
damage.
CAUTION: Burn hazard. Surfaces are hot when the
unit is in operation. Do not touch the piping, pumps,
heat exchanger, and tanks until the equipment has been
given enough time to cool down. Failure to follow these
instructions could result in property damage and/or
moderate personal injury.
