Install New Safety Devices & Sensors
6.1
Install Digital Phase Monitor
Number the wires on the old phase monitor (you will be
landing these wires in the same points on the new digital
phase monitor). Once numbered, remove the wires from
the old phase monitor, then remove the old phase monitor
from the unit.
Mount the new digital phase monitor (DPM) using two
screws in the same position that the old phase monitor was
located. You may need to either make space or find a
nearby location to fit the DPM in.
Once the new DPM is mounted, connect the existing
numbered wires to match numbered points on the new
DPM using female spade connectors.
Pull a 2-conductor cable from the DPM to the future i-
Controller location in the electrical cabinet.
6.2
Install Refrigerant Pressure Transducers
Remove existing suction transducers from circuits 1&2.
Discard this transducers and cables.
Install the 0-500 PSI Suction transducers on the suction
lines of circuits 1,2,3&4. Install the 0-667 PSI Discharge
transducers on the liquid lines of circuits 1,2,3&4. If there
are spare service ports on the unit, install the transducers
on a spare service port. If spare service ports are not
available, use a refrigerant tee.
Using the provided transducer whips, plug the blue whips
into the new suction transducers and the yellow whips into
the new discharge transducers. Run the whips back to the
future i-Controller location in the electrical cabinet.
6.3
Replace Reheat/Reclaim Surface-Mount Probe
If there is a temperature probe currently on the
Reheat/Reclaim inlet, remove and discard probe and cable.
Secure the new temperature probe on the inlet piping for
the Reheat/Reclaim service of the unit. If there are 2 stages
for Reheat/Reclaim both probes will be used. Run the temp
probe sensor wires back to the future i-Controller location
in the electrical cabinet.
6.4
Install Float Switch
Connect the float switch to the provided bracket using the
provided washer and nut.
Mount the provided bracket so that the base of the bracket
is roughly 2 inches from the drain pan base and located at
the front left corner of the drain pan, on the supply fan wall
(see figure 2 for positioning requirements)
