NOTE: For the equipment warranty to be valid, certain piping installation and startup procedures are required. WhisperKOOL procedures are expected to be followed and completed by the installing certified HVAC/R service technician. The technician shall be required to be equipped with the proper tools of the trade, including: refrigerant 134a, brazing equipment, dry nitrogen, and an accurate manifold gauge set (preferably digital), plus a four-valve manifold set for evacuation, digital micron gauge, digital scale, deep vacuum pump and accurate digital thermometers. Without the proper equipment, a professional job cannot be accomplished.

5. DATA RECORDINGS

If you use digital instruments like a refrigerant manifold, voltmeter, or thermometer, please attach a photograph showing the accurate readings to the back of this document. There's no need to fill out sections 1-6 for your submission in this case Readings Mandatory Below:

Statement: Check for visible bubbles in the sight glass when the system is operational. If bubbles are detected, it may be necessary to add refrigerant. Persistent bubbles could indicate moisture contamination in the system.

1a. Head pressure PSIG at the liquid line king valve:

This pressure reading is taken at the high side of the condensing unit and will range from 100-200 Psi. This pressure is commonly known as "High Side Pressure". Using a calibrated manifold, this pressure is taken at the liquid line service valve.

1b. Head pressure which is converted to temperature:

This reading is pressure converted to temperature. This reading is provided from the R134a Pressure Temperature Conversion Chart. Example: 216.3 Psi =136˚FThis pressure is commonly known as "High Side Pressure". Using a calibrated manifold, this pressure is taken at the liquid line service valve.

2a. Temperature of liquid line at the liquid line king valve:

This measurement is the actual temperature of the copper line at the liquid line king valve. Using a calibrated thermometer tightly secure the sensor with electrical tape to ensure solid contact to the surface of the copper line. Insulate the sensor to ensure there is no temperature influence from the condenser exhaust air. This will ensure you are reading the correct copper line temperature and not the surrounding air temperature.

2b. Sub-cooling calculation:

The subcooling calculation is the head pressure converted to temperature subtracted from the liquid line temperature. Equation - head pressure converted to temperature subtracted from the liquid line temperature. WhisperKOOL cooling units achieve optimum performance with a 5˚F subcooling at an ambient of 85˚F.

3a. Suction pressure PSIG at the suction service valve:

This is the pressure reading taken at the low side of the condensing unit and will range from 24-50 Psi. This pressure reading is commonly known as "Low Side Pressure". Using a calibrated manifold, this pressure is taken at the Suction service valve.

3b. Suction pressure converted to temp:

This reading is pressure converted to temperature. This reading is provided from the R134a PT Conversion Chart. Example: 30.4 Psi = 35˚F

4a. Temp of suction line at the service valve:

This measurement is the actual temperature of the copper line at the suction line service valve.

4b. Superheat calculation:

The superheat calculation is the temperature of the suction line subtracted from the suction pressure converted to temperature. Equation - the temperature of the suction line subtracted from the suction pressure converted to temperature. (k-j = l)

5. Temp. of air entering the condensing unit:

The temperature of air entering the coil of the condensing unit is commonly known as "Ambient Air". Using a calibrated thermometer, place the sensor in the center of the condensing unit coil, 1 inch from touching any surface. Using a calibrated thermometer, place the sensor in the center of the coil, or return grille 1 inch from touching any surface.

6a. Voltage to Condensing Unit (running):

Voltage is taken with a calibrated volt meter. Measure the voltage going from the connections going into the condensing unit for power. The system is rated for 120V (Unless stated 220 on condensing unit). Voltage must be between 113-130 Volts.

6b. Amp. draw at the time of data recording (running):

Using a calibrated amp meter, clamp the meter onto the "hot wire". This will be the black wire in the electrical box. Amps must not exceed manufacturing rating on the name plate.

7a. Line set length:

7b. Is there a vertical rise? If YES, what is the length?

8a. Liquid line installed tubing diameter OD:

8b. Suction line installed tubing diameter OD:

9a. Temp of return air entering evaporator coil (dry bulb):

Temperature of air entering the evaporator cooling unit, commonly known as "Return Air". Using a calibrated thermometer, place the sensor in the center of the coil, or return grille 1 inch from touching any surface.

9b. Temp of supply air leaving unit (dry bulb):

Temperature of air leaving the evaporator cooling unit, commonly known as "Supply Air". Using a calibrated thermometer, place the sensor in the center of the air flow, 1 inch from touching any surface. Using a calibrated thermometer, place the sensor in the center of the coil, or return grille 1 inch from touching any surface.

10. Temperature difference between return air and supply air (9a - 9b):

The temperature difference between return air temperature and supply air temperature of the evaporator cooling unit is commonly known as "Delta". Equation: Return Air subtracted from Supply Air. (a-b = Delta T) Using a calibrated thermometer, place the sensor in the center of the coil, or return grille 1 inch from touching any surface.

11. Was a condensation drain test performed?

If the answer is NO: Pour water into the drain pan to verify that the unit is draining properly.

12a. Cellar Room Ambient Temperature:

12b. Condenser Ambient Temperature:

Ensure that airflow into and out of both the condenser and evaporator is clear of obstructions. The condensing and evaporator units should each have a minimum clearance of three feet for their supply and return, although five feet is ideal for optimal performance.

Disclaimer:

Split System Warranty: A limited 2-year product warranty is offered with all split systems. While the warranty starts at the date of purchase, this warranty is not activated until a Product Warranty Checklist has been submitted and approved by WhisperKOOL.
