Start-Up/Commissioning
Operation
For new installations, ensure the unit is ready to operate by
going through the Checklist for Completed Installation,
located in
, prior to start-up.
Note:
A Warranty Registration and Start-Up Checklist is
provided with the unit data package. 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.
Start-Up Instructions
WARNING
Hazardous Voltage and Rotating
Components!
Failure to follow instructions below could result in
death or serious injury. During installation, testing,
servicing and troubleshooting of this product it may be
necessary to work with live and exposed rotating and
electrical components. Have a qualified or licensed
service individual who has been properly trained in
handling exposed rotating and electrical components
perform these tasks.
1. Ensure that the control circuit breakers, fan power
switch (motor starter protectors) and additional built in
optional equipment power switches are turned on.
2. Close all cabinet doors and replace all equipment
removed prior to performing start-up checks.
3. Apply power to the CyberAir system at the main power
disconnect switch.
4. Turn on the A/C unit using the system controller and set
the desired values (set points) for room temperature
and humidity. (Refer to the separate controller
operating instructions included in the data package
with your unit.)
5. Ensure that all fans are rotating correctly and freely
without any unusual noise.
6. Test cooling operation by setting the temperature set
point below actual room temperature. The compressor
should come on and the discharge air should feel
cooler than the return air.
Both refrigeration circuits must be tested at start-up. There
are several ways to force the second circuit into operation.
Refer to the E² Controller IOM sent in the data package with
your unit.
7. Test humidification operation by creating a demand for
humidification. Use an amp meter to determine
current draw of the humidifier. Visually check for vapor
leaving the steam head or feel if the cylinder is warm
to verify if the humidifier is operational.
Note:
In all cases, 1 to 6 hours might be required to
achieve the 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.
8. Test dehumidification operation by creating a demand
for dehumidification. If necessary, set the
dehumidification set point 10% below actual room
conditions, (the set point may already be below actual
room conditions, especially at start-up). The
compressor will energize to begin the
dehumidification process. While in this mode, room
temperature may decrease and the reheat function
may activate. As conditions in the room change, you
may have to readjust the set point as you check opera-
tion.
9. For electric reheat, use an amp meter on the heater
circuit to determine if the heater is operational. For Hot
Water Reheat ensure that the control signal has
energized the hot water control valve and the
temperature of the water has decreased as it passes
through the unit. In all cases, 1 to 6 hours might be
required to see a desired level of humidity in the
conditioned space. Once room conditions have been
programmed or set, a repeat visit to the conditioned
site may be required to ensure the dehumidification
mode is meeting the room’s requirements.
Microprocessor Controller Programming
The microprocessor controller is factory programmed
based on the features selected with the system. A user
provided BMS may be used to directly interface to the
controller. The operator may view all the available menu
screens through a BMS, however, changes may be made
only to basic parameters such as adjusting set points and
setting and acknowledging alarms. More advanced
parameter adjustments may be made through the user
interface display. Operating instructions for the controller
are provided separately.
