Guide Specifications

sense and display suction temperature.

E.Control Power Transformer: Converts unit power voltage to 120-1-60 (500 VA capacity). Factory mounting includes primary- and secondary-wiring between the transformer and the control panel.

F.Motor Current Module: Capable of monitoring com- pressor motor current. Provides extra protection against compressor reverse rotation, phase-loss and phase imbalance. Options consists of one module per electrical system. (Factory mounted)

G.Power Factor Correction Capacitors: Provided to correct unit compressor factors to a 0.90-0.95.

H.Condenser Coil Environmental Protection:

1.Pre-Coated: Epoxy coated aluminum fin stock to guard from corrosive agents and insulate against galvanic potential. For mild seashore or industrial locations.

2.Copper Fin: Provide copper fins in lieu of aluminum.

3.Post-Coated Dipped: Dipped-cured coating on condenser coils for seashore and other corro- sive applications (with the exception of strong alkalis, oxidizers, and wet bromine, chlorine and fluorine in concentrations greater than 100ppm).

I.Protective Condensing Unit Panels (Factory or Field Mounted):

1.Louvered Panels (condenser coils only): Painted steel as per remainder of unit cabinet, over external condenser coil faces.

2.Wire Panels (full unit): Heavy gauge, welded wire-mesh, coated to resist corrosion, to protect condenser coils from incidental damage and restrict unauthorized access to internal com- ponents.

3.Louvered Panels (full unit): Painted steel as per remainder of unit cabinet, to protect condenser coils from incidental damage,visually screen internal components, and prevent unauthorized access to internal components.

4.Louvered/Wire Panels: Louvered steel panels on external condenser coil faces, painted as per remainder of unit cabinet. Heavy gauge, welded wire-mesh, coated to resist corrosion, around base of machine to restrict unauthorized access.

J. Service Isolation valves: Service suction and dis- charge (ball type) isolation valves are added to unit per system. This option also includes a system high pressure relief valve in compliance with ASHRAE

15.(Factory-mounted.)

K.Hot Gas By-Pass: Permits continuous, stable opera- tion at capacities below the minimum step of unload- ing to as low as 5% capacity (depending on both the unit & operating conditions) by introducing an artificial load. Hot gas by-pass is available installed on one or both refrigerant circuit(s).

L.Microprocessor Membrane Keypad Graphics on in lieu of Standard English:

1.French language.

2.German language.

3.Spanish language.

4.Italian language.

M.Chicago Code Relief Valves to meet Chicago Code requirements.

N.Building Automation System (EMS) Reset Interface: Condensing Unit to accept 4 to 20mA, 0 to 10 VDC, or discrete contact closure input to reset the dis- charge air temperature.

O.Remote Control Panel (Field Mounted): Auxiliary panel for remote user interface for functions nor- mally made at the unit control center. Available on YCUL0016-0090 models.

P.OptiView Remote Control Panel (Field-mounted) Graphical interface panel to remotely control and monitor up to 8 units

Q.Sound Reduction (Factory Mounted):

1.Low speed, reduced noise fans

2.Compressor Acoustic Sound Blankets

R.Vibration Isolation (Field Mounted):

1.Neoprene Pad Isolators.

2.1 Inch Deflection Spring Isolators: Level adjust- able, spring and cage type isolators for mount- ing under the unit base rails.

3.2 Inch Deflection Seismic Isolators: Level adjustable, restrained mounts in rugged welded steel housing with vertical and

horizontal limit stops. Housings shall be designed to withstand a minimum 1.0g accel-
