Airflow Balancing
Overview
Airflow balancing is an important part of operation and unit commissioning. The design conditions especially for
static pressures are not expected to meet actual conditions and thus adjustments will need to be made. The MPK unit
is able to maintain a self-balancing condition with its Smart Air ManagementTM feature but must first be properly
configured.
Guidelines for Performing a Proper Airflow Balance
PoolPak LLC recommends that the air balance be performed by an independent air balancing contractor. In addition
to supplying the proper tools, a good air balancing contractor will follow the below guidelines:
• Supply a report with all the below recorded design and actual data.
• Take a representative traverse of the duct to attain good readings for supply, return, exhaust, and outdoor air
flows. This may require additional traverses for a particular air inlet depending on the duct installation.
• Record the following design and actual data for all supply, return, exhaust, and outdoor air flows:
• Air flow rates
• Static pressure readings
• Fan speeds and power consumption (fan amps on D cab only)
• All motorized damper set points for each set of data
• Record the above data at both the minimum and maximum operating modes:
• Purge mode (or 100% outside air)
• Unoccupied mode (or 0% outside air)
PoolPak requires the above information as complete as possible. This information is needed to adequately configure
the MPK unit to attain the desired ventilation.
Controller Adjustments
The controller airflow parameters can be adjusted to properly balance the airflow entering and leaving the MPK
unit. PoolPak recommends that this procedure be done at unit startup and therefore a full procedure is part of the
PoolPak MPK Start Up Procedure.
Troubleshooting
Overview
The below section is a brief description of general features of the PoolPak CPCS controller that can be used in
troubleshooting fault conditions that arise with the PoolPak unit.
System Status Information
To aid in troubleshooting, the CPCS controller contains all of the pertinent system status information to let the
user know the current operation status of the PoolPak unit. Many alarms can be diagnosed and resolved just by
reviewing the system status information. The below is a list of the conditions and possible causes depending on the
type of condition:
ALARMNAME:
Below is a list of all alarms as displayed on the controller and possible causes:
Freeze = Freeze Warning – Supply Temp too low (< 40F)
