Louvered Panels (Condenser Coil Only)
– Louvered panels are mounted on the sides
and ends of the condenser coils for protection.
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. Unre-
stricted 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).
Sound Attenuation
– One or both of the following sound attenuation options are recom-
mended 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 absor-
bent textile fiber of 5/8” (15mm) thickness and 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.
Ultra Quiet Fans
– Lower RPM, 8-pole fan motors are used with steeper-pitch fans.
Vibration Isolators – Level adjusting, spring type 1” (25.4mm) or seismic deflection or
neoprene pad isolators for mounting under unit base rails.
CONTROL OPTIONS:
Ambient Kit (Low) –Units will operate to 32°F (-4°C) (standard). This accessory includes
all necessary components to permit condensing unit operation to 0°F (-18°C). (This op-
tion includes the Discharge Pressure Transducer / Readout Capa bility option.) For proper
head pressure control in applications below 25°F (-4°C) where wind gusts may exceed
five mph (eight km/h), it is recommended that Optional Condenser Louvered Enclosure
Panels also be included.
Building Automation System Interface – The factory addition of a Printed Circuit Board
to accept a 4-20 milliamp, 0-10VDC or contact closure input to reset the discharge air tem-
perature from a Building Automation System. (The standard control panel can be directly
connected to a Quantech Building Automated System via the standard on board RS485
communication port.)
Language LCD And Keypad Display – Spanish, French, German, and Italian unit LCD
controls and keypad display avail able. Standard language is English.
Discharge Pressure Transducers And Readout Capability – the addition of pressure
trans ducers allows models to sense and display discharge pressure. (This option as in-
cluded with either the low or high ambient kits).
Suction Pressure Transducers And Readout Capability – The addition of suction
transduc ers allows models to sense and display suction pressure.
Suction Temperature Readout – The addition of tem perature sensors allow models to
sense and display suction temperature.
Motor Current Module – Capable of monitoring com pressor motor current. Provides
extra protection against com pressor reverse rotation, phase-loss and phase imbalance.
Option consists of one module per electrical system.
