48GP (N) 024-060, 48JZ (N) 024-060 50GL 024-060, 50JZ 024-060 ICM FIOP Installation Instructions Installation, Start-Up, and Operating Instructions NOTE: Read the entire instruction manual before starting the installation. TABLE OF CONTENTS SAFETY CONSIDERATIONS .
Approved for outdoor installation on wood flooring or on class A, B or C roof covering materials. Before performing service or maintenance operations on system, turn off main power to unit and install lock-out tag. Turn off accessory heater power switch if applicable.
The ICM motor uses the selected taps to modify its operation to a pre-programmed table of airflows. The unit must be configured to operate properly with system components with which it is installed.
(2.) AC/HP Size-Factory selected to match system size, please verify. (3.) SYSTEM TYPE-Factory selected on 48GP system AC- AIR CONDITIONER. (4.) AC/HP CFM ADJUST-Select HIGH for 042 & 048, NOM for 036 & 060, and LO for 024 & 030.. (5.) ON/OFF DELAY-Factory selected 0/90 profile.
b. COOLING MODE (1.) If indoor temperature is above temperature set point and humidity is below humidity set point, thermostat closes circuits R to G, R to Y/Y2 and R to O—The unit delivers single speed cooling airflow. c. COOLING MODE-DEHUMIDIFICATION (1.
(4.) ENH (enhanced) selection provides a 30 sec. cooling & heat pump on delay with no airflow, plus 150 seconds at 70 percent airflow and no off delay for added comfort. This will minimize cold blow in heat pump operation and could enhance system efficiency.
to a level which causes the Thermidistat™ to close its contacts. When the contacts close, the airflow will return to 100 percent of selected cooling airflow.
and continuous operation. (See Tables 16, 17 & 18 for airflow delivery and minimum CFM.) Note that airflow marked is the airflow which will be supplied in emergency heat mode and heating mode on air conditioners when electric heat is the primary heating source.
This configuration provides the following comfort enhance- ments: (a.) A 30 sec blower on delay with 150 sec at 70 percent airflow to allow the indoor coil to warm up or cool down before the blower is.
value. If circuit R to G is open (0–v.) for super dehumidify mode, the motor delivers reduced airflow to maximize the humidity removal of the system while minimizing over cooling. e. ELECTRIC HEATING MODE (1.) Thermostat closes circuit R to W/W1, or W2—The unit delivers the selected electric heat airflow.
(2.) COOLING MODE— Press MODE button on the Thermidistat™ until COOL icon is displayed. Cooling begins within 10 sec. and remains on for 4 minutes. Observe that compressor, outdoor fan and indoor blower motors start after the call for Cooling. At the end of 4 minutes, the cooling cycle stops and the MODE reverts back to OFF .
cooling cycle remains ‘‘on’’ until the room temperature drops to point that is slightly below the cooling control setting of the room thermostat. At this point, the thermostat ‘‘breaks’’ the circuit between thermostat terminal R to terminals Y and G.
f. Loosen set-screw that secures wheel to motor shaft, remove screws that secure motor mount brackets to blower housing, and slide motor and motor mount out of blower housing. 2. Remove and clean blower wheel as follows: a. Ensure proper reassembly by marking wheel orientation.
