PGD1 Remote Interface Unit (RIU) Installation
PoolPak Part #: 24-0145
Manufacturer: Carel
PPK Models: PoolComPak (ECCPCP), RoofPak (ECCPCP), PoolPak MPK (ICC)
INTRODUCTION
The Remote Interface Unit (RIU) is the main user interface for the ECCPCP and ICC control
systems. It can be installed at the PoolPak unit or in another convenient location up to 1000 feet
away. Each PoolPak supports connection to as many as three RIUs. All status, set points and
configuration points are available through the RIU.
MOUNTING
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.
Warning!
Failures due to mounting the keypad inside the pool room will not be covered under warranty.
The wall mounting of the terminal first requires the back piece (A) of the RIU assembly. The RIU
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. A ¾” hole must be drilled for the 6-conductor cable which connects the
remote interface unit to the PoolPak unit. See figure below and detailed instructions.
1. Fasten the back piece (A) to the gang box
using the rounded-head screws supplied in
the packaging. Use the screws that come
with the box to secure the bracket.
2. Thread the 6-conductor cable through the
back piece (A) and connect to the back of
front panel (B).
3. Rest the front panel (B) on the back piece
A and fasten the parts together using the
flush-head screws supplied in the packaging.
4. Finally, fit the click-on frame (C).
