3.4. Splitter Kits
3.4.1. Overview
Two-way splitter (P/N 275-0304) and three-way
splitter (P/N 275-0305) kits for a zone are used with
the RLDS to allow you to pinpoint critical points of
the refrigeration system, and allow further monitoring
in small spaces with a high probability for leakage.
Splitter kits allow you to place more sensors in each
zone, which enable potential leaks to be detected
more quickly.
3.4.2. Installation
Sensors can be installed on walls, drains, or areas with
potential air flow. Any ¼” tubing can be used to
configure the two or three point sensors.
The alarm setpoint must be changed due to the
averaging effect of the splitter system. The pick-up
lines for the splitter tube must be the same length from
the splitter to each of the end-of-line filters to balance
the splitter system and create the averaging effect.
A two-way splitter kit requires reduction of the
original alarm setpoint by ½ so the setpoint becomes
half of the original value. A three-way splitter kit
requires reduction of the original setpoint by ⅓ so the
setpoint becomes a third of the original value.
For example, if the alarm setpoint alarm value is
1000, with a two-way splitter the value becomes 500
PPM. With a three-way splitter the value becomes
333 PPM.

CAUTION: Keep pick-up tube the same length
to create the averaging effect of the splitter
system. Point the filter vertically downward or
horizontally with a slight downward tilt to
avoid moisture collecting in the filter from
condensation.
