1.1 Purpose of Manual
This manual is furnished to acquaint you with some
of the practical ways to install, operate, and maintain
this unit. Read it carefully before doing any work on
your unit and keep it handy for future reference.
Equipment cannot operate well without proper care.

mended installation and servicing procedures out-
lined in this manual.
1.2 Safety
1.2.1 Safety Alert Symbol
SAFETY INSTRUCTION
This safely alert symbol will be used in this manual
and on the unit safety instruction to draw attention to
safety related instructions. When used the safety alert
symbol means
ATTENTION BECOME ALERT!
YOUR SAFETY IS INVOLVED! FAILURE TO FOL-
LOW THIS INSTRUCTION MAY RESULT IN A
SAFETY HAZARD.
1.2.2 Safety Instruction Decal
Your Technologic 5500 Series Variable Primary Pump
and Valve Controller should have a safety instruction
decal (part # S11550). If the decal is missing or
illegible contact your local B&G representative for a
replacement.
1.2.3 Motor Safety
Each motor must have a properly sized starter with
properly sized overload block to provide overload
and undervoltage protection. Ground fault protection
should be sized properly. Refer to local electrical
codes for sizing and selection. Refer to the motor
manufacturer's I.O.M. (Installation Operation Manual)
for specific installation information. Even when the
motor is stopped, it should be considered "alive" as
long as its controller is energized.
The use of motor disconnect switches is acceptable.
Consult the factory for proper interlocking with
adjustable frequency drives, AFD's. See section 1.9.
1.2.4 Motor Control Equipment Safety
Motor control equipment and electronic controls are
connected to hazardous line voltages. When servic-
ing electronic controls, there will be exposed compo-
nents at or above line potential. Extreme care should
be taken to protect against shock. Stand on an insu-
lating pad and make it a habit to use only one hand
when checking components. Always use accurate
test meters when checking electrical components.
Always work with another person in case of an emer-
gency. Disconnect power when performing mainte-
nance. Be sure equipment is properly grounded.
Wear safety glasses whenever working on electronic
control or rotating equipment.
1.3 Storage
For long periods of storage, the unit should be cov -
ered to prevent corrosion and contamination from
dirt. It should be STORED in a clean, dry location
between -20 and +60ºC. 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.
NOTE: EXTENDED STORAGE OF AFDs MAY
REQUIRE SPECIAL ATTENTION PRIOR TO START-
UP. SEE MANUFACTURER'S I.O.M. FOR DETAILS.
1.4 Handling
Care should be taken to prevent damage due to
dropping or jolting when moving the Technologic Vari-
able Primary Pump and Valve Controller. Transporta-
tion damage should be brought to the carrier's atten-
tion immediately upon receipt.
1.5 Temperature and Ventilation
All electrical equipment is susceptible to failure if
operated in ambient temperatures outside of its rat-
ing. The operating temperature range for this unit is
0 to 40°C. The relative humidity should not exceed
95% non-condensing. The unit should not be oper-
ated outside these extremes.
1.6 Input Voltage
The Technologic Variable Primary Pump and Valve
Controller was factory set to operate on the voltage
shown on the nameplate. Check the AFD nameplate
for the proper input and output voltages before wiring
the AFD.
The voltage tolerance is +10/-5% and phase to
phase voltage must not have an imbalance greater
than 5 VAC.
