WARNING!
When economizer option is selected, adequate exhaust capacity via a separate fan must be specified to
ensure the natatorium pressure remains slightly negative. Failure to specify adequately sized exhaust
system may result in damage to structure and pool odors may be forced into other areas of the building.
OUTSIDE AIR TEMPERATURE SENSOR (ECONOMIZER OPTION ONLY) (4)
The outside air temperature sensor is installed only when the outside air economizer option is included. The sensor is
mounted inside a 1/2” PVC conduit pull elbow. It can be mounted to the outside of the building using standard PVC
conduit fittings. The sensor should be mounted near the outside air intake vent for the economizer system. It is very
important to mount the sensor so that it does not receive direct sunlight. The exposure to sunlight will cause the sensor
housing to warm, resulting in temperature readings that are higher than the actual air temperature. This condition may
prevent the ECC-PCP from selecting the economizer mode of operation. If possible, mount the sensor under an overhang
or on a surface with a northern exposure.
Electrical connection should be made with 22 AWG, copper, 2-conductor, shielded, twisted-pair cable. Connect the
shield drain wire to ground at the PoolComPak™ end only. See figure below for an illustration of the outside air
temperature sensor. Seal the conduit leading to the sensor with silicone caulk to prevent moisture from migrating out to
the sensor and condensing inside the sensor.

AIR COOLED CONDENSER (OPTIONAL) (5)
The air-cooled condenser is used to reject heat recovered during the space cooling mode of operation. Only
PoolComPak™ brand air-cooled condensers (PAC Units) should be used with a PoolComPak™ Unit. The ECC-PCP
provides 24 VAC control signal to the speed control located in the PAC unit control panel. The speed control then runs
the condenser fan motor at the appropriate speed. See figure below for an illustration of a PAC unit field wiring.
