PRGA and PRGB Purifier Purge
Older model Purifier purges can be connected to the Symbio™
control panel. A compressor run contact will be used to give the
purge an auto start contact when the chiller is running. Use
similar wiring options as discussed for PRGC models. The
exception is that a pilot relay needs to be driven from the Quad
relay output. The contacts of the quad relay are only rated for
2.8 A pilot duty, 7.2 A resistive at 120 Vac and 1/3 HP, 7.2 FLA
at 240 Vac, 5 A general purpose. Refer to the existing purge
wiring diagram to determine the connection points for this auto
start contact.
PRGC Purifier Purge
The PRGC Purifier™ purge uses UCP2-based
communications and does not communicate with Tracer
AdaptiView™ controls. A PRGC requires a compressor
running signal connected to J26, 1 and 2 on 3U1 in the purge
to operate in the auto or adaptive modes. Use the Compressor
Running contact closure from the quad relay LLID - 1A8,
connected to 115 Vac purge power source.
PRGD, PRGG and PRGF EarthWise™
Purge
If a stand-alone EarthWise™ purge (CH530 control) exists on
the chiller, it will need some hardware changes to work with the
Symbio™ retrofit controls. If the purge is a new installation with
the Symbio™, then skip to
1. The Compressor running LLID (3A6) will not be needed,
disconnect and remove.
2. The Condenser Saturated Refrigerant Temperature LLID
(purge liquid temperature) will not be needed, disconnect
and remove.
3. The existing 120-27 Vac transformer and DC power supply
in the purge is undersized and should be removed. The
purge control will be powered by the Symbio™ panel
power supply.
4. Remove and save purge power supply LLID.
5. Remove IPC bus cable from power supply LLID. (Ensure
remaining LLIDs are still connected to IPC bus).
6. It is optional to remove and discard the wires (303A, 304A,
and 318A) from control power transformer to this power
supply LLID (3A5).
7. Disconnect the cable from the DynaView to the power
supply LLID.
8. Remove the tilt bracket from the purge base. DynaView
can remain attached to the tilt bracket panel.
9. Connect the IPC bus from the control panel to the IPC bus
for the purge using an IPC bus cable.

Hazardous Voltage w/Capacitors!
Failure to follow instructions below could result in
death or serious injury.
Disconnect all electric power, including remote
disconnects and wait for DC capacitors to discharge
before servicing. Refer to the manufacturer's
recommendations for proper discharge time as DC bus
capacitors retain hazardous voltages after input power
has been disconnected. Follow proper lockout/ tagout
procedures to ensure the power cannot be
inadvertently energized. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged before touching any internal components.

PPE for Arc/Flash Required!
Failure to wear appropriate PPE could result in death or
serious injury.
On this unit, if the handle shield is cracked the circuit
breaker could arc/flash when reset. To avoid being
injured, technicians MUST put on all necessary
Personal Protective Equipment (PPE), in accordance
with NFPA70E for arc/flash protection, PRIOR to
entering the starter panel cabinet.

LonTalk
Option Installation
Symbio™ 800 system uses a U60 LON module through the
USB connection instead of the LCI-C LLID.
1. Install the U60 LON module (KIT18458; Echelon Module
Field Install kit) on the DIN rail on the door, put it at left side
of Symbio™ 800.
2. Connect U60 LON module to Symbio™ 800 by USB cable
which is provided with the module connect this cable to any
one of the four USB ports under the Symbio™ 800
controller.
3. Connect U60 LON module to the BAS system using
shielded cable.
