EXAMPLE: Air fl ow requirements are calculated as follows: (Having a wet coil creates additional resistance to air fl ow. This addit ional resistance must be taken into consideration to obtain accurate air fl ow information. External Static Pressure External Static Pressure can best be de fi ned as ...

The Vert-I-Pak A series units must be installed with a free return air configuration. The table below lists the indoor airflow at corresponding static pressures. All units are rarted at low speed. The Vert-I-Pak units are designed for either single speed or two fan speed operation. For single speed ...

A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more diffi cult and time consuming, if not (in some cases) entirely impossible. The refrigera...

Refrigerant Charging Proper refrigerant charge is essential to proper unit opera-tion. Operating a unit with an improper refrigerant charge will result in reduced performance (capacity) and/or effi ciency. Accordingly, the use of proper charging methods during ser-vicing will insure that the unit is...

3. Install a process tube to sealed system. 4. Make necessary repairs to system. 5. Evacuate system to 200 microns or less. 6. Weigh in refrigerant with the property quantity of R-410A refrigerant. 7. Start unit, and verify performance. 8. Crimp the process tube and solder the end shut. Proper safet...

METERING DEVICE Capillar y Tube Systems All units are equipped with capillary tube metering devices. Checking for restricted capillary tubes. 1. Connect pressure gauges to unit. 2. Start the unit in the cooling mode. If after a few minutes of operation the pressures are normal, the check valve and t...

NOTE: System operating pressures must be near normal before valve can shift . REVERSING VALVE DESCRIPTION/OPERATION The Reversing Valve controls the direction of refrigerant fl ow to the indoor and outdoor coils. It consists of a pressure-operated, main valve and a pilot valve actuated by a solenoid...

Reversing Valve in Heating Mode When sluggish or stuck in the mid-position, part of the discharge gas from the compressor is directed back to the suction side, resulting in excessively high suction pressure. Should the valve fail to shift from coooling to heating, block the air fl ow through the out...

8. Pressurize sealed system with a combination of R-410A and nitrogen and check for leaks, using a suitable leakdetector. Recover refrigerant per EPA guidelines. 9. Once the sealed system is leak free, install solenoid coil on new valve and charge the sealed system by weighing in the proper amount a...

Remove the leads from the compressor terminals and set the ohmmeter on the lowest scale (R x 1). Touch the leads of the ohmmeter from terminals common to start (“C” to “S”).
