START-UP/COMMISSIONING
AND UNIT SHUTDOWN
3.1
Operation
For new installations, ensure the unit is ready to operate by
completing the Start-Up Checklist contained in the data
package that accompanied your unit.
NOTE
A Warranty Registration and Start-Up Checklist
is provided in the unit data package. It should be
completed during start-up and sent to STULZ. This
checklist should be used as a guideline for items
that need to be confirmed during start-up.
Start-up must be performed by a journeyman, refrigeration
mechanic or an air conditioning technician.
3.2
Step by Step Start-Up Instructions
1.
Replace all equipment removed prior to performing the
start-up checks.
2.
Apply power to the CyberOne EC CW system at the main
power disconnect switch.
3.
Ensure that all blowers and fans are rotating correctly
and freely without any unusual noise.
4.
Test cooling operation by setting the temperature set
point below the actual room temperature to create a
demand for cooling. The discharge air should feel cooler
than the return air.
5.
Test optional heating operation by adjusting the tempera-
ture set point above the actual room temperature. The
source of heat should be energized to increase discharge
air temperature.
For Electric Reheat, use an amp meter on the heater
circuit to verify the heater is operational. For Hot Water
Reheat, ensure the control signal has energized the
control valve and the temperature of the water has
decreased as it passes through the unit.
6.
If a humidifier is present, test humidification operation
by creating a demand for humidification. Use an amp
meter to determine current draw of the humidifier. Visu-
ally check for vapor leaving the steam head or feel if the
cylinder is warm to verify the humidifier is operational.
In all cases, one to six hours might be required to see
a desired level or rise in humidity in the conditioned
space. Once room conditions have been programmed
or set, a repeat visit to the conditioned space may be
required to ensure the humidifier is meeting the room’s
requirements.
An Operation and Maintenance manual for the humidifier
is provided with your unit under separate cover. Refer
to that manual for detailed information on humidifier
operation.
3.3
Microprocessor Controller
Programming
The
E
2
microprocessor controller is factory programmed
based on the model of the A/C system and optional features
selected. Most applications require no field start-up or
program adjustment beyond setting the current date and time.
Separate operating instructions for the controller have been
sent with your unit, including each feature’s factory “default”
setting and the available adjustment range, if applicable.
3.4
Unit Shutdown
To shut down the unit, command the shutdown from the
BMS managing the unit or use the user interface terminal
connected to the unit controller to power down the unit, as
described in the controller operator manual.
To perform an emergency shutdown, set the main power
disconnect switch to the Off position.
