Discharge Pressure Transducers and Read-
out Capability
The addition of pressure transducers allows models to
sense and display discharge pressure. This is recom-
mended for brine chilling applications. (This option
is included with either the low or high ambient kits)
(Factory-Mounted).
Suction Pressure Transducers
Permits unit to sense and display suction pressure. This
capability is standard on YCAL0041-0071 models.
Motor Current Module
Capable of monitoring compressor motor current. Pro-
vides extra protection against compressor reverse rota-
tion, phase-loss and phase imbalance. Option consists
of one module per electrical system (Factory-Mount-
ed).
Optiview Remote Control Panel
Graphical interface panel to remotely control and mon-
itor up to 8 dierent units. (Refer to form 201.18-SG4
for detailed information).
Multi-Unit Sequencing
A separate Sequencing Control Center is provided to
handle sequencing control of up to eight chillers in par-
allel based on mixed liquid temperature (interconnect-
ing wiring by others). (Only one of following options
can be oered on a unit at a time: BAS, Remote Con-
trol Panel or Multi-unit Sequence Control) (Factory-
Mounted).
Compressor, Piping, Evaporator Options
Low Temperature Brine
Required for brine chilling below 30°F (-1°C) leaving
brine temperature for YCAL0041 - 0071 models. Op-
tion includes resized thermal expansion valve (Facto-
ry-Mounted).
Chicago Code Relief Valves
Unit will be provided with relief valves to meet Chi-
cago code requirements (Factory-Mounted).
Service Isolation Valve
Service suction and discharge (ball type) isolation
valves are added to unit per system. This option also
includes a system high pressure relief valve in compli-
ance with ASHRAE 15 (Factory-Mounted).
Hot Gas By-Pass
Permits continuous, stable operation at capacities be-
low the minimum step of compressor unloading to as
low as 5% capacity (depending on both the unit and
operating conditions) by introducing an articial load
on the cooler. Hot gas by-pass is installed on only re-
frigerant system #1 on two-circuited units (Factory-
Mounted).
DX Cooler 300 psig (21 Bar) DWP Waterside
The waterside will be of 300 psig (21 bar) instead of
the standard 150 psig DWP. 300 psig R.F. anges are
included on the DX cooler nozzles (Factory-Mount-
ed). The companion anges will be eld-supplied by
others.
Flanges (Victaulic Type)
Consists of two (2) Flange adapters for grooved end
pipe (standard 150 psi [10.5 bar] cooler).
Flow Switch
The ow switch or its equivalent must be furnished
with each unit.
150 psig (10.5 Bar) DWP
For standard units. Johnson Controls model F61MG-
1C Vapor-proof SPDT, NEMA 4X switch (150 psig
[10.5 bar] DWP), -20°F to 250°F (-29°C to 121°C),
with 1” NPT connection for upright mounting in hori-
zontal pipe (Field-Mounted).
300 psig (21 Bar) DWP
For units with optional 300 psig (21 bar) DX cooler.
McDonnell & Miller model FS74W Vapor-proof
SPDT, NEMA 4X switch (300 psig (21 bar) DWP),
-20°F to 300°F (-29°C to 149°C), with 1¼ inch MPT
connection for upright mounting in horizontal pipe
(Field-Mounted).
Dierential Pressure Switch
Alternative to an above mentioned ow switch. Pre-
tempco model DPS300AP40PF-82582-5 (300 psi max.
working pressure), SPDT 5 amp 125/250 VAC switch,
Range 0 to 40 PSID, deadband 0.5 to 0.8 psi, with
1/4 in. NPTE Pressure Connections.
