TM TM
If the PoolPak™ is to be mounted on another manufacturer’s curb, the PoolPak™ factory must be notified of this at the
time the PoolPak™ sales order is submitted. PoolPak™ units produced for curb mounting, whether on a PoolPak™ curb
or on another manufacturer’s curb, receive special weatherizing and insulating that non-curb mounted PoolPak™ units do
not receive.
NOTE
If the factory is not notified that a PoolPak is to be curb mounted, the PoolPak base
will not be watertight, it will leak, and it will not be properly insulated.
For SR series units, the compressor end of the curb must have a special weather tight pan with the weather seal under
the bulkhead between the compressor and return air compartments. The pan under the compressor compartment has
provisions for running the pool water lines through the cap and isolates the area under the curb from the compressor
compartment and from possible pool water or oil leaks as well as from the ambient conditions present in the compressor
compartment.
ECCIII CONTROLS FIELD WIRING
OVERVIEW
The ECC III is the Electronic Control Center programmable controller designed specifically for the PoolPak™
dehumidification system. It is a robust system capable of a variety of functions. The following text describes the field
wiring required for proper operation of the ECC dehumidification system in a typical PoolPak™ unit installation. The
field wiring diagram, Figure 4-1 , shows the location of the connections for the sensors and other required devices. The
numbers following the text identifies the location on the field wiring diagram showing how each field wired device is
connected to the PoolPak™ unit electrical panel.
REMOTE INTERFACE UNIT (1)
The Remote Interface Unit (RIU) allows the user to view space temperature, relative humidity and pool water
temperature. It also provides the ability to change set points, receive alarm notifications, and perform advanced
diagnostic functions.
The RIU should be mounted in a convenient location, outside the natatorium, that is protected from splashing pool water
and corrosive air. The ambient temperature of the mounting location must always be greater than 32°F. The maximum
distance from the PoolPak™ control panel is 1,000 feet. For distances greater than 1,000 feet, contact the factory.
!
CAUTION
Mounting the RIU inside the natatorium may cause damage to the unit. Problems
occurring from mounting the RIU in the natatorium will not be covered under war-
ranty.
The ECC III includes a 7-foot long, black RJ25 cable. If the RIU is to be mounted directly to the PoolPak™ unit, this
cable can be plugged directly into port J10 on control module CM1 in the PoolPak™ control panel.
For remote mounting of the RIU, the installing contractor must run a six-conductor (three twisted pairs), 16-20 AWG cable
from the PoolPak™ control panel to the remote location. One end of this cable will terminate on terminal block T17 in
the control panel. The other end will terminate on a factory-supplied RJ25 jack. The wires for terminals T17.1 and T17.2
should be from the same twisted pair. The second pair should be used for T17.3 and T17.4 and the third pair for T17.5 and
T17.6. Proper polarity and connection is essential for correct operation of the RIU. Improper wiring can cause permanent
damage. Please review the color code and connections to the RJ25 jack carefully.
