Specially Engineered
Engineered to be ducted above ceiling applications
The Mini-Plus Ceiling Unit is designed for environments where floor space is at a premium and a bit more cooling is required. The Mini-Plus is available in a wide range of system configurations and capacities from 2.5 to 5 tons, and functions independently from other building air conditioning and ventilation systems.

INSTALLATION, OPERATION & MAINTENANCE MANUAL
CONTROL SYSTEM
Data Alarm Mini Processor 4: The microprocessor based Data Alarm Mini Processor 4 is wall mounted and has a single row, 16 character liquid crystal display (LCD) in clear vernacular format. The Data Alarm Mini Processor 4 not only controls and monitors your room’s temperature, humidity, air flow and cleanliness, but also provides alarm history and an automatic self-test of the microprocessor system start-up. Multiple messages will be displayed by automatically scrolling from each message to the next. Multiple alarms will be displayed sequentially in order of occurrence.
ELECTRICAL
All electrical components including capacitors, relays, and control transformers are pre-wired. Each unit is provided with a microswitch to prevent condensate pan overflow. The microswitch will disable the unit prior to pan overflow should the drain line become plugged with debris.
ELECTRIC REHEAT
6 kW reheat is standard on 2.5 through 4 ton Mini-Plus units (5 ton Mini-Plus units have 6 kW reheat on single phase and 12 kW reheat on three phase). Electric reheat is accomplished with low watt, low density finned tube fabricated of stainless steel core sheath with plated fins to withstand moist conditions. Reheat is installed on the air discharge side of the cooling coil and provides ample capacity to maintain room drybulb conditions during dehumidification. Low-watt density coils eliminate ionization associated with open air electric resistance heating.
CABINET
Mini-Plus indoor sections are constructed with tubular steel frames for strength and service access. Removable galvanized steel panels are lined with 1 inch thick, 1-1/2 pound density insulation for quiet and efficient operation. An integral filter section with 2″ filters is standard.

For applications with space restrictions water cooled systems may be ordered as split systems. The evaporator section and compressor sections (see Water Cooled – Packaged Systems) are shipped separately. Field piping and wiring is required between the evaporator and compressor sections. Field supplied return and supply air ductwork is required for all Mini-Plus evaporator sections. A dry cooler (fluid cooler) or water cooling source is required on water cooled systems.
CHILLED WATER SYSTEMS
Blower Section/Coil Section: The blower section contains a double width, double inlet blower with belt drive and a variable pitch sheave and blower motor. The self-aligning ball bearings are rated for a minimum life of 100,000 hours. The chilled water coil and chilled water valve are housed in the blower section as well. The chilled water coil is constructed of copper tube and aluminum fins. Utilizing chilled water from an existing chilled water loop, water flow is controlled by a 2-way valve for accurate and economical temperature control and dehumidification. The drain pan is constructed from stainless steel. Field supplied return and supply air ductwork is required for all Mini-Plus blower sections.
EXTENDED COMPRESSOR WARRANTIES
Extended compressor warranties are available for periods of twenty-four (24) or forty-two (42) months in addition to the standard factory eighteen (18) month warranty. These warranties are for the replacement of compressors and do not include labor.
