COOLING SYSTEM
• Designed to maximize sensible and latent cooling
performance at design conditions
• System can operate from -18°C to 52°C without any
additional controls
R-410A Refrigerant
• Non-chlorine based
• Ozone friendly
Scroll Compressors
• Scroll compressors on all models for high performance,
reliability and quiet operation
• Resiliently mounted on rubber grommets for quiet
operation
Compressor Crankcase Heaters
• Protects against refrigerant migration that can occur
during low ambient operation
Thermal Expansion Valves
• Assures optimal performance throughout the application
range
• Removable element head
Filter/Driers
•
High capacity filter/drier protects the system from dirt
and moisture
High Pressure Switches
• Protects the compressors from overload conditions
such as dirty condenser coils, blocked refrigerant flow, or
loss of outdoor fan operation
Low Pressure Switches
• Protects the compressors from low pressure conditions
such as low refrigerant charge, or low/no airflow

PERFORMANCE/QUALITY AND CE MARK OPTION
PERFORMANCE/QUALITY
• Cooling performance is rated at test conditions included in Air-Conditioning, Heating and Refrigeration Institute (AHRI)
Standard 340/360 while operating at rated voltage and air volumes
• Components bonded for grounding to meet safety standards for servicing required by Underwriters Laboratories (UL)
and the International Electrotechnical Commission (IEC)
• International Organization for Standardization (ISO) 9001 Registered Manufacturing Quality System
CE MARK OPTION
•
The CE mark has been added to our rooftop product line as a configure to order (CTO) option
• This optional construction allows units to be sold into countries requiring CE marking for rooftop products
•
CE marked units meet the requirements of the Machinery Directive 2006/42/EC, Low Voltage Directive
73/23/EEC, EMC Directive 89/336/EEC, and Gas Directive 90/396/EEC
•
Declaration of conformity certificates will be provided for each CE marked unit on demand
• Key features of this option over and above standard product features are:
•
Touch-proof electrical components meeting the requirements of EN 60529
• Branch circuits over 0.5 kW load have overcurrent protection
•
Rotary style/finger safe disconnect switch with locking handle prevents disconnect door from being opened with the
power on
• Padlock can be applied to lock the disconnect switch in the OFF position
• The factory wiring has been redesigned for separation of high and low voltage circuits
FEATURES AND BENEFITS
Freezestats
• Protects the evaporator coil from damaging ice build-
up due to conditions such as low/no airflow, or low
refrigerant charge
Condenser Coil - Environ™ Coil System
(092 through 120 models only)
• Lightweight, all aluminum brazed
fin construction
• Constructed of three components
•
A flat extrusion tube
•
Fins in-between the flat
extrusion tube
• Two refrigerant manifolds
Environ™Coil System Features:
• Improved heat transfer performance due to high primary
surface area (flat tubes) versus secondary surface (fins)
• Smaller internal volume (reduced refrigerant charge)
• High durability
• All aluminum construction
• Fewer brazed joints
• Compact design
• Reduced unit weight
•
Easy maintenance/cleaning
• Face split design
• Mounting brackets with rubber inserts secure coil to unit
providing vibration dampening and corrosion protection
