1 Installing the Pump
Site Requirements
A suitable environment is important to ensure optimum performance of the
nano pump.
Power Consideration
The nano pump power supply has wide ranging capability (see Table 1 on page
3). It accepts any line voltage in the range described in the above mentioned
table. Consequently there is no voltage selector in the rear of the nano pump.
There are also no externally accessible fuses, because automatic electronic
fuses are implemented in the power supply.
Power Cords
Different power cords are offered as options with the nano pump. The female
end of each of the power cords is identical. It plugs into the power-input socket
at the rear of the nano pump. The male end of each of the power cords is
different and designed to match the wall socket of a particular country or
region.
WARNING
To disconnect the nano pump from line, unplug the power cord. The power supply
still uses some power, even if the power switch on the front panel is turned off.
CAUTION
Shock hazard or damage of your instrumentation can result, if the devices are
connected to a line voltage higher than specified.
WARNING
Never operate your instrumentation from a power outlet thathas no ground
connection. Never use a power cord other than the power cord designedfor your
region.

1100 Series Nano Pump Service Manual 3
Installing the Pump 1
Bench Space
The nano pump dimensions and weight (see Table 1) allow to place the nano
pump on almost any laboratory bench. It needs an additional 2.5 cm
(1.0 inches) of space on either side and approximately 8 cm (3.1 inches) in the
rear for the circulation of air and electric connections.
If the bench should carry a complete Agilent 1100 Series system, make sure
that the bench is designed to carry the weight of all the modules.
Environment
Your nano pump will work within specifications at ambient temperatures and
relative humidity as described in Table 1.
WARNING
Never use cables other than the ones supplied by Agilent Technologies to ensure
proper functionality and compliance with safety or EMC regulations.
NOTE
The pump should be operated in a horizontal position!
CAUTION
Do not store, ship or use your nano pump under conditions where temperature
fluctuations could cause condensation within the nano pump. Condensation will
damage the system electronics. If your nano pump was shipped in cold weather, leave
it in its box and allow it to warm slowly to room temperature to avoid condensation.

Unpacking the Nano Pump
Damaged Packaging
Upon receipt of your nano pump, inspect the shipping containers for any signs
of damage. If the containers or cushioning material are damaged, save them
until the contents have been checked for completeness and the nano pump has
been mechanically and electrically checked. If the shipping container or
cushioning material is damaged, notify the carrier and save the shipping
material for the carrier’s inspection.
Delivery Checklist
Ensure all parts and materials have been delivered with the nano pump. For
this compare the shipment content with the checklist included in the
instrument box. Please report missing or damaged parts to your local Agilent
Technologies sales and service office.
Accessory Kit
Each shipment contents an accessory kit with the necessary tools to install
the pump and to have an operating system.
CAUTION
If there are signs of damage to the nano pump, please do not attempt to install the
nano pump.

Installing the Pump 1
Optimizing the Stack Configuration
If your nano pump is part of a complete 1100 series system, you can ensure
optimum performance by limiting the configuration of the system stack to the
following configuration. This configuration optimizes the system flow path,
ensuring minimum delay volume.
NOTE
If a single stack configuration becomes too high, e.g. if an additional module like a G1330B
ALS Thermostat is added or if your bench is too high, a two stack configuration may be a
bettersetup.Separatethestackbetweenpumpandsamplerandplacethestackcontaining
