Features/Benefits

Every compact one-piece

unit arrives fully assembled,

charged, tested, and ready to

run.

Cooling EERs

The 48/50HJ015 (12 tons) and 017

(15 tons) units provide ARI (Air Condi-

tioning and Refrigeration Institute) cer-

tified cooling EERs (Energy Efficiency

Ratios) of 10.6/10.7 and 10.5/10.8,

respectively. The fully-rated 20-ton

48/50HJ025 has an EER of 9.3/9.5.

These exceptionally high ratings assure

minimum operating costs and will qual-

ify for attractive utility rebates in many

areas.

Durable, dependable construction Designed for durability in any climate, the weather-resistant cabinets are constructed of galvanized steel, bonderized, and all exterior panels are coated with a prepainted baked enamel finish. The paint finish is non-chalking, and is capable of withstanding ASTM B117 500-hour Salt Spray Test. All internal cabinet panels are primed, permitting longer life and a more attractive appearance for the entire unit.

Features/Benefits (cont) For units without economizer, yearround ventilation is enhanced by a manual outdoor-air damper. The damper can be preset to admit up to 25% outdoor air. In addition, the barometric relief damper or power exhaust accessory can be utilized to help maintain proper building pressure. Quiet, efficient operation and dependable performance Scroll compressors have vibration isolators for extremely quiet operation. Efficient fan and motor design permits operation at very low sound levels.

HUMIDISTAT MOISTUREMISER % RELATIVE HUMIDITY Field-installed, wall-mounted humidistat is used to control operation of the MoistureMi$er dehumidification package. The humidistat controls the occupied space humidity at a user-selected setting between 20% and 80% relative humidity. MOISTUREMI$ER DEHUMIDIFICATION PACKAGE The MoistureMi$er dehumidification package is a factory-installed option that provides increased dehumidification by cooling the hot liquid refrigerant leaving the condenser coil.

Controls Operating sequence Cooling, units without economizer — When thermostat calls for cooling, terminals G and Y1 are energized. The indoor (evaporator) fan contactor (IFC) and compressor contactor no. 1 (C1) are energized, and evaporator-fan motor (IFM), compressor no. 1 and condenser fan(s) start. The condenser-fan motor(s) runs continuously while unit is cooling. When the thermostat calls for a second stage of cooling by energizing Y2, compressor contactor no. 2 (C2) is energized and compressor no.

TEMP systems A TEMP System is a network of communicating Carrier TEMP System Thermostats and rooftop, factory-mounted Apollo direct digital controls, each serving its own zone and heating/cooling unit. Networking allows your building manager to easily access each of your systems from a single location...whether they are in the same building or located throughout town.
PAGE 60
Controls (cont) Variable Volume/Variable Temperature VVT® Systems VVT Systems are dedicated to total building comfort. Carrier thermostats, zone dampers, and HVAC equipment with factory-mounted direct digital controls continually monitor and adjust their operation to ensure uninterrupted and personalized comfort for all occupants.
PAGE 61
VVT® application guidelines The installer is responsible for ensuring that the bypass controller is configured and the system is balanced so that the minimum airflow is higher than 300 cfm/ton. To accomplish proper configuration set the System Setup Enable Function (Category 5, option 7) to ON. This will close the bypass damper and force all of the zone dampers to open.
PAGE 62
Controls (cont) If the diversity within the space does not vary much, then bypass can be installed as shown in the diagram below successfully. Care must be taken to ensure that maximum bypass air at part load conditions does not exceed 25% of the full load airflow. The bypass junction must be installed with sufficient duct length between it and the unit to allow complete mixing of the bypass air an the return air.
PAGE 63
Monitor thermostat configuration — The monitor thermostat controls the operation of its own zone and of each associated zone controller. The monitor thermostat determines system operation from the information received from each device that it controls. The monitor thermostat must be configured for proper control of the system. Part of the configuration is Category 4.0, which deals with HVAC settings. The Category 4.0 HVAC Equipment table shows the default settings for this category.

Application data Ductwork Minimum temperature (48HJ015-025 only) Ductwork should be attached to the curb on all units. Interior installation may proceed before unit is set in place on roof. If ductwork will be attached to the unit, do not drill in condensate drain pan area — leaks may result. See figures on page 65 for information on field-installed concentric ductwork when applicable. Air entering the heat exchanger in heating must be a minimum of 50 F (10 C) continuous and 45 F (7.2 C) intermittent.

Application data (cont) Applications — There are many different rooftop unit applications that are susceptible to problems caused by high humidity levels. Some common applications include: • Restaurants: The kitchen areas of restaurants have many humidity producing activities such as dish washing and cooking. • Supermarkets: High humidity levels cause inefficiency in operation of refrigeration and freezer systems. • Museums and Libraries: Humidity can damage books and artwork.
