Remote Evaporators
Wiring for Remote Evaporators
Condensing unit electrical information should be based on the
packaged chiller and can be found beginning on page 64 .
Refrigerant Specialties Kit
Remote evaporator units include a Refrigerant Specialties Kit
which supplies the following field-installed components and are
noted on page 28 :
• Expansion Valve
— Models 030-070 use Thermal Expansion Valves (TXV)
with optional Electronic Expansion Valves (EXVs)
— Models 075-241 use EXVs
• Liquid Line Solenoid Valve and DIN Connector
• Liquid Line Filter Drier with Filter Drier Core and Clamp
• Liquid Line Sight Glasses
• Liquid Line Ball Valves
• Charging Valve
• Suction Line Temperature Sensor Tube
• Schrader and Schrader Core for Suction Line
Transducers
• Suction Pressure Transducer
•
Check Valve for Hot Gas Bypass Line (specific installation
requirements)
Sensor Wiring
The Remote Evaporator AGZ-E units come with long sensor
wires for the remote evap installation. The sensor wires to the
evaporator include the following:
• Evaporator Water Inlet and Outlet Temperature Sensor
• Suction Line Temperature Sensors for Piping at the
Evaporator for both Circuit #1 and #2
• Suction Transducer Wiring for Installation on Evaporator
Suction Piping for both Circuit #1 and #2
NOTE:
When splicing is required, the connections must be
soldered together and individually shrink wrapped to
be made water resistant and shield maintained.
For all AGZ-E models with a remote evaporator, the leaving
water temperature sensor is to be located in the well in the
provided spool piece pipe. The 2 water temperature sensors
supplied have 110 feet length of cable coiled behind the unit
control panel, intended for extension to the evaporator.
There is one suction line refrigerant temperature sensor per
circuit installed on suction line with 110 feet of cable coiled
behind the unit control panel, intended for extension to the
evaporator. Place the sensor in a brazed well (provided in
kit, installed in the field) on the suction line in a straight-flat
area, close to the suction line pressure transducer. Install with
heat conductive compound and insulate well. If installed on a
horizontal pipe run, locate between the 2-4 o’clock positions,
or, on a TXV, locate the bulb and equalizer line on suction line
at the 3 or 9 o’clock position.
There is one suction line pressure transducer per circuit with
approximately 90 feet of cable coiled for all unit models,
installed on the suction line behind the unit control panel
for extension to the evaporator. Mount the transducer in the
suction line, 1-2 feet from the evaporator braze connections,
on the top or side of the pipe. Connection is ¼-inch flare with a
flare Schrader.
Expansion Valve Consideration
For AGZ-E models 030-070 using TXVs, the valves must
be located within 12 inches of the evaporator liquid line
connections. The 1/4” equalizer lines must be attached to the
suction tubes near the evaporator outlet downstream of the
TXV sensing bulb.
For AGZ-E installations using EXVs, the valves must still be
located within 12 inches of the evaporator inlet connection -
see “Field Installed Component Locations” on page 21.
The electronic expansion valve has a 40 foot long cable
attached and can be used, when the outdoor unit is less than
40 feet away. Beyond that, a junction box must be located
within 40 feet of the evaporator, and an additional length of
14GA wire connected from the cable to the unit, allowing up to
a total distance given in Table 4 . The expansion valve wiring
cannot run in conduit with other wiring that is over 24 volts.
AC shielding must cover the wiring from the unit to the EXV,
including the splice connection. Shielding must cover the
entire length of wiring run and bonded at the chiller. NOTE: 14
AWG wire gauge sizes will use Beldon part number 83754 or
equivalent.
