RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.

ATTENTION INSTALLING PERSONNEL

As a professional installer you have an obligation to

know the product better than the customer. This

includes all safety precautions and related items.

Prior to actual installation, thoroughly familiarize

yourself with this Instruction Manual. Pay special

attention to all safety warnings. Often during

installation or repair it is possible to place yourself

in a position which is more hazardous than when

the unit is in operation.

Remember, it is your responsibility to install the

product safely and to know it well enough to be able

to instruct a customer in its safe use.

Safety is a matter of common sense...a matter of

thinking before acting. Most dealers have a list of

specific good safety practices...follow them.

The precautions listed in this Installation Manual

are intended as supplemental to existing practices.

However, if there is a direct conflict between existing

practices and the content of this manual, the

precautions listed here take precedence.

Safety Instructions RECOGNIZE SAFETY SYMBOLS, WORDS, AND LABELS The following symbols and labels are used throughout this manual to indicate immediate or potential safety hazards. It is the owner’s and installer’s responsibility to read and comply with all safety information and instructions accompanying these symbols. Failure to heed safety information increases the risk of personal injury, property damage, and/or product damage.

General This manual covers only the installation of the remote cooling unit. For information on accessories, see the unit “Specification Sheet”. DO NOT locate the unit: — Directly under a vent termination for a gas appliance. — Within 3 feet of a clothes drier vent. — Where water may rise into the unit. – Where the noise would prove to be a nuisance to the customer (i.e. windows, patios, decks, etc.

Refrigeration Piping SWEAT CONNECTIONS AT THE UNIT NOTE: When brazing, use a brazing alloy of 2% minimum silver content. Do not use flux. REFRIGERANT VAPOR AND LIQUID LINE SIZING See unit “Specification Sheet” for the required vapor and liquid line tubing sizes. The listed sizes in the specification sheet are suitable for line lengths of fifty feet or less and indoor coil elevations of no more than forty feet above or below the outdoor unit. NOTE: Unit performance is affected by vapor line tubing size.

WARNING 4. Open the hand valve a minimal amount on the line coming from the nitrogen cylinder. 5. Open the high pressure valve on the manifold gauge. Pressurize the refrigerant lines and the indoor coil to 150 psig (1034 kPA). To reach 150 psig, you may need to further open the hand valve on the nitrogen cylinder. To avoid possible explosion: • Never apply flame or steam to a refrigerant cylinder. If you must heat a cylinder for faster charging, partially immerse it in warm water.

c. Open the vacuum gauge valve (D) and evacuate to 250 microns or less. If the system cannot be evacuated, replace the vacuum pump equipment and repeat steps (a) through (c) again. Otherwise, the pump and gauge are operating properly and you can continue on to the next step; evacuating the system. Before proceeding, be sure to close the valve to the vacuum gauge to avoid “pegging the meter” and potential gauge damage.

correct wire gauge and necessary length of run for proper wiring. System Startup 1. Route the power supply and ground wires through the high voltage entrance in the unit. Connect the power supply wires to the contactor. Connect the ground wire to the ground lug. 2. Route the low voltage wiring through the low voltage entrance in the unit. Connect the low voltage wires to the terminal strip. 3. If an Amana approved room thermostat is not already present, install one at a suitable indoor location.

If pressures and amp draw are too high, remove charge. Troubleshooting If you are not using the “Matched Combination” which is listed on the unit "Specification Sheet", check subcooling (TEV coils) or superheat (flowrator coils) as detailed below. (QUALIFIED SERVICER ONLY) When troubleshooting, the first step should always be to check for clean coils, clean filter(s), and proper airflow. Indoor airflow should be 350 to 450 CFM per ton of cooling, based on the size of the outdoor unit.

System Checklist 1 Does the condenser fan blade rotate freely, and is it tight on the shaft? 2 Does the refrigerant tubing flex freely and not touch another tube to cause rub through? 3 Are both indoor and outdoor sections level? 4 Are the units properly supported? 5 Is outdoor section properly located on concrete base or equivalent? 6 Are the refrigerant lines correctly installed according to the relative position of the outdoor and indoor sections? 7 Is the refrigerant tubing properly supported by iso
