Page 8: General Operation
General Operation Refrigerant Cycle (Cooling Mode) The CFH1012A uses R-454B refrigerant in a conventional vapor-compression refrigeration cycle to transfer heat from air in an enclosed space to the outside. A supply blower assembly pulls indoor air across the evaporator. Liquid refrigerant passing through the evaporator is boiled into gas by heat removed from the air. -

Page 10: Electronic Control Board Mode Of Operation
Electronic Control Board Mode of Operation Normal 24 VAC power must be continuously applied to “R” and “C”. Upon a call for cooling “Y” and with the high pressure switch (HPS) closed, the compressor will be energized. (Note: See the delay on make feature.) The compressor will remain energized during the 3 minute timed low pressure by-pass cycle. -
Page 11: Figure 3. Control Board Detail
High Pressure Switch The high pressure switch is mounted on the liquid line. It is electrically connected to a lockout circuit on the board which shuts down the system if the refrigerant pressure rises to 650 PSIG. This protects the unit if airflow through the condenser is blocked or if the outdoor fan motor fails. Although the contacts of the high pressure switch close when the refrigerant pressure falls to approxi- mately 450 PSIG, the system must be manually reset once the lockout circuit is activated. -

You must consider all of the following when choosing the installation site: 1. Evaporator Condensate Drainage. Condensate produced during operation must be discharged from the evaporator pan through the primary and/or secondary drain hoses. Make sure the condensate lines are free of any restrictions. Condenser Pan Drainage. - Page 14 Other Optional Equipment: The package may include other factory-supplied items (optional) as follows: PART # DESCRIPTION 50123 Digital thermostat. 1 stage heat, 1 stage cool. 7 day programmable.

Porting and Duct Work General Information Note: The following instructions are for general guidance only. Due to the wide variety of installa- tion possibilities, specific instructions will not be given. When in doubt, follow standard and accepted installation practices, or contact ICE for additional assistance. Minimum Airflow Requirements The duct system must be engineered to assure sufficient air flow through the CFH1012A, even under adverse conditions such as dirty filters, etc. -
Page 16: Mounting The Unit
Figure 4. Wall Mounting Detail Mounting the Unit 1. Using an appropriate and safe lifting device, set the CFH1012A on the bottom support bracket mounted on the wall. You must stabilize the unit on the bracket with the lifting device or by some other means - the bracket alone is not sufficient. -
Page 17: Figure 5. Thermostat Wiring Diagram
Important All electrical work must meet the requirements of local codes and ordinances. Work should be done only by qualified persons. The CFH1012A units are provided with labeled power leads and an eight-conductor thermostat cable. High Voltage Wiring The high voltage wire provided with the CFH1012A can be replaced to eliminate wire nut connec- tions. -

Low refrigerant. 2. Check for proper charge and possible refrigerant leak. 3. - Page 24 2. Running Amperage: Connect a clip-on type ammeter to the (common) lead to the compressor. Turn on the supply voltage and energize the unit. The compressor will initially draw high amperage; it should soon drop to the RLA value or less. If the amperage stays high, check the motor winding resistances.

Page 25: Scheduled Maintenance
Chapter 5 Maintenance Scheduled Maintenance Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. -
Page 26: Chapter 6 Service & Charging/Recovery
Chapter 6 Service & Charging/Recovery Safety Precautions Service Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the REFRIGERATING SYSTEM, the following shall be completed prior to conducting work on the system. 1. -
Page 27: Charging Procedures
Charging Procedures In addition to conventional charging procedures, the following requirements shall be followed. 1. Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them. 2. - Page 28 10. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of the flammable refrigerant. If in doubt, the manufacturer should be consulted. In addition, a set of calibrated weighing scales shall be available and in good working order.
