User's Manual Part 3

DESCRIPTION
At last - air conditioners designed specifically for cooling electronic enclosures that can be used for both indoor and outdoor applications right out of the
box!
No more bulky unattractive weather hoods... No more worries over what options to specify for outdoor applications.
Expertly designed and crafted, the A
DVANTAGE Series boasts a stylish appearance with rounded edges, no visible hardware and a textured baked
powder finish to blend easily with contemporary enclosure designs.
Servicability has been made easier by incorporating a “knock-down” sheetmetal design which provides quick access to internal components.
Standard features include heavy duty galvanized steel construction with baked-on powder paint, environmentally friendly refrigerants, built-in
condensate evaporator, thermostatic low temperature control and EMI/RFI Suppressor. These air conditioners are available in capacities from
1,000 to 22,000 BTU/H in seven heights, all utilizing the exclusive KOOLTRONIC M/TAB integral mounting system.
KOOLTRONIC also designs and manufactures a variety of Air Conditioners to meet unique specifications. We invite your inquiries about our
modification and custom-design capabilities.
STANDARD FEATURES
CLOSED-LOOP COOLING: The enclosure interior airflow system is isolated from the ambient airflow system. Ambient air can not invade the cool,
dehumidified sensitive component compartment.
BALL-BEARING MOTORS: All fan motors are UL/CSA Recognized and include automatic-reset thermal overload protection and double-sealed or
double-shielded precision ball bearings. Special permanent lubricants in the tube axial fans perform over a broad temperature range: -20°F [-28.9°C] to
250°F [121.1°C].
RUGGED CONSTRUCTION: Precision-engineered heavy gauge steel construction of all cabinets and blowers insures Air Conditioners will stand up
under tough applications.
TEXTURED BAKED POWDER FINISH: Durable, baked-on textured beige powder finish is standard. Other finishes are available.
POWER: Available in 230 VAC, 50 Hz or 60 Hz.
REFRIGERANT: Low Ozone Depleting Potential (ODP) R22 Refrigerant is used in all Advantage RP55 Series Air Conditioners and are being con-
verted to CFC-free R134a Refrigerant as compressors become available. Consult KOOLTRONIC for status at time of requirement.
PERMANENT FILTERS: Multi-layer grid of sturdy, corrugated aluminum in an aluminum frame. May be reused after washing off accumulations and
spraying with A-16 Recoating Adhesive.
CONDENSATE EVAPORATOR: Built-in Condensate Evaporator eliminates need for draining condensate under normal operating conditions. May
not be adequate in extremely high humidity with open or leaky enclosure. Overflow condensate drain fitting and hose are included.
LOW AMBIENT KIT: Maintains sufficient operating pressures when ambient temperatures drop below 50°F [10°C]. Includes a compressor heater and
pressure actuated condenser blower cycling control.
LOW TEMPERATURE CONTROL: Thermostatic Low Temperature Control prevents over-cooling and provides energy-efficient operation.
EMI/RFI SUPPRESSOR: EMI/RFI Suppressor minimizes transient line spikes during on/off cycling.
CRANKCASE COMPRESSOR HEATER: 240V heater attached to the compressor crankcase to maintain appropriate temperatures during cold
operating conditions.
HEAD PRESSURE CONTROL SWITCH: A control device to minimize compressor cycling and prevent evaporator coil icing.
POWER CORD: All models have six foot [1.8m] SJT-type 3-wire power cords with appropriate plugs.
INSULATION: All cold components, lines and the evaporator compartment are insulated with high-performance insulation for maximum efficiency.
GASKETING: All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA 3R Enclosure Rating.
QUALITY ASSURANCE: Refrigeration system components are kept sealed until charged with refrigerant; all brazed joints are thoroughly leak-tested;
each unit is functionally tested before shipment.
INSTALLATION: Detailed Installation and Operator's Manual, with drawings, mounting plan and spare parts list is included with each unit.
UL/CUL RECOGNIZED: All Advantage RP55 models are UL/CUL Recognized. All Recognized models are available as Listed at added cost.
ACCESSORIES AND OPTIONS
**
FACTORY-INSTALLED OPTIONS:
COOLING EFFECT DETECTOR: A thermostat is mounted inside the cabinet and attached to a sensor in the warm air return. When the air
temperature increases to the set point, a signal is sent to a terminal block. User-installed wiring from the terminal block to local and/or remote warning
devices (light, bell, siren, etc.) can be for normally open or closed operation.
Append letter "B" to Part No.
ENCLOSURE HEATER: 240V fin strip heater, installed singly or ganged, used to maintain desired internal enclosure temperature, under cold oper-
ating conditions.
Single Heater, append letter "F" to Part No.
Double Heater, append letter “G” to Part No.
