Options and Accessories

temperature. (Factory mounted).

MOTOR CURRENT MODULE – Capable of monitoring compressor motor current. Provides extra protection against compressor reverse rotation, phase-loss and phase imbalance. Option consists of one module per electrical system. (Fac- tory-mounted.)

REMOTE CONTROL PANEL AND WALL ADAPTOR–(Avail- able on the YCUL0016 - 0090 models only) (Only one of fol- lowing options can be offered on a unit at a time: BAS, Remote Control Panel, OptiView Remote Graphic Panel, or Multi-unit Sequence Control). (Field mounted).

OPTIVIEW REMOTE CONTROL PANEL - Graphical interface panel to remotely control and monitor up to 8 different units. (Refer to form 201.18-SG4 for detailed information)

COMPRESSOR AND PIPING OPTIONS:

CHICAGO CODE RELIEF VALVES – Unit will be provided with relief valves to meet Chicago code requirements. (Fac- tory-mounted).

HOT GAS BY-PASS – Permits continuous, stable operation at capacities below the minimum step of compressor unload- ing to as low as 5% capacity (depending on both the unit and operating conditions) by introducing an artificial load. Hot gas by-pass is available installed on refrigerant system #1 or on both systems of two circuited units. (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 compliance with ASHRAE 15. (Factory-mounted.)

CONDENSER AND CABINET OPTIONS:

Condenser coil protection against corrosive environments is available by choosing any of the following options. For addi- tional application recommendations, refer to FORM 150.12- ES1. (Factory-mounted).

PRE-COATED FIN CONDENSER COILS – The air-cooled condenser coils are constructed of black epoxy-coated aluminum fins. This can provide corro- sion resistance comparable to copper-fin coils in typical seashore locations. Either these or the post-coated coils (below), are recommended for units being installed at the seashore or where salt spray may hit the unit.

POST-COATED DIPPED CONDENSER COILS – The unit is built with dipped-cured condenser coils. This is another choice for seashore and other corrosive appli- cations (with the exception of strong alkalies, oxidizers and wet bromine, chlorine and fluorine in concentrations

greater than 100 ppm).

COPPER-FIN CONDENSER COILS – The unit constructed with condenser coils which have copper fins. (This is not recommended for units in areas where they may be exposed to acid rain).

ENCLOSURE PANELS (UNIT) – Tamperproof Enclosure

Panels prevent unauthorized access to units. Enclosure Panels can provide an aesthetically pleasing alternative to expensive fencing. Additionally, for proper head pressure control, YORK recommends the use of Condenser Louvered Panels for winter applications where wind gustss may exceed five miles per hour. The following types of enclosure panels are available:

WIRE PANELS (Full Unit) – Consists of welded-wire- mesh guards mounted on the exterior of the unit. Prevents unauthorized access, yet provides free air flow. (Factory- mounted).

WIRE/LOUVERED PANELS – Consists of welded-wire- mesh panels on the bottom part of unit and louvered panels on the condenser section of the unit. (Factory-mounted).

LOUVERED PANELS (Condenser Coil Only) – Louvered panels are mounted on the sides and ends of the condenser coils for protection. (Factory-mounted).

LOUVERED PANELS (Full Unit) – Louvered panels sur- round the front, back, and sides of the unit. These prevent unauthorized access and visually screen unit components. Unrestricted air flow is permitted through generously sized louvered openings. This option is applicable for any outdoor design ambient temperature up to 115°F (46°C). (Factory- mounted).

SOUND ATTENUATION – One or both of the following sound attenuation options are recommended for residential or other similar sound sensitive locations:

COMPRESSOR ACOUSTIC SOUND BLANKET – Each compressor is individually enclosed by an acoustic sound blanket. The sound blankets are made with one layer of acoustical absorbent textile fiber of 5/8" (15mm) thickness; one layer of anti-vibrating heavy material thickness of 1/8" (3mm). Both are closed by two sheets of welded PVC, reinforced for temperature and UV resistance. (Factory- mounted).

LOW SOUND FANS – Lower RPM, 8-pole fan motors are used with steeper-pitch fans. (Factory-mounted).

VIBRATION ISOLATORS – Level adjusting, spring type 1" (25.4mm) or seismic deflection or neoprene pad isolators for mounting under unit base rails. (Field mounted).
