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 warranty.
The Remote Interface Mounting Plate MUST be mounted on an extra deep,
single gang electrical box. Do not mount flush to the wall.

CPCS Controls Field Wiring
OVERVIEW
The CPCS is the 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 CPCS dehumidification system in a typical PoolPak unit installation. The field wiring diagram (see Section VI
- Wiring) shows the location of the connections for the sensors and other required devices. The numbers following
the text identify 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, space 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.
The CPCS 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.
The RIU includes a mounting bracket that is designed to fit a single gang, extra deep electrical box mounted
horizontally in the wall. The RJ25 jack and most of the black cable should be placed inside the box before installing
the mounting bracket. Use the screws that come with the box to secure the bracket. A ¾” hole must be drilled for
the 6-conductor cable which connects the remote interface unit to the PoolPak unit. Refer to the figure 4-4 for remote
interface unit mounting dimensions.
