VAPOR LINE SIZING AND COOLING CAPACITY LOSSLONG LINE APPLICATION: An application is considered”Long line” when the total equivalent tubing length exceeds80 ft. (24.38 m) or when there is more than 20 ft. (6.09 m)vertical separation between indoor and outdoor units.These applications require additional accessories andsystem modifications for reliable system operation. Themaximum allowable total equivalent length is up to 250 ft.(76.2 m). The maximum vertical separation is 200 ft.
(60.96 m) when outdoor unit is above indoor unit, and upto 80 ft. (24.38 m) when the outdoor unit is below theindoor unit. Refer to Accessory Usage Guideline below forrequired accessories. See Longline Application Guidelinefor required piping and system modifications. Also, refer tothe table below for the vapor tube diameters based on thetotal length to minimize the cooling capacity loss.

NOTES:
1. Ratings are net values reflecting the effects of circulating fan motor heat. Supplemental electric heat is not included.
2. Tested outdoor/indoor combinations have been tested in accordance with DOE test procedures for central air conditioners. Ratings for other combinationsare determined under DOE computer simulation procedures.
3. Determine actual CFM values obtainable for your system by referring to fan performance data in fan coil or furnace coil literature.
4. Do not apply with capillary tube coils as performance and reliability are significantly affected.

accessories and descriptions for specific featuresand available enhancements.
Accessory Description and Usage (Listed Alphabetically)1. Ball−Bearing Fan MotorA fan motor with ball bearings which permits speed reductionwhile maintaining bearing lubrication.2. Compressor Start Assist − Capacitor and RelayStart capacitor and relay gives a ”hard” boost to compressormotor at each start up.
Usage Guideline:Required for reciprocating compressors in the following applications:
Long lineLow ambient coolingHard shut off expansion valve on indoor coilLiquid line solenoid on indoor coil
Required for single−phase scroll compressors inthe following applications:
Long line
Low ambient coolingSuggested for all compressors in areas with ahistory of low voltage problems.
3. Crankcase HeaterAn electric resistance heater which mounts to the base ofthe compressor to keep the lubricant warm during off cycles.Improves compressor lubrication on restart and minimizesthe chance of liquid slugging.
Usage Guideline:Required in low ambient cooling applications.Required in long line applications.Suggested in all commercial applications.
4. Evaporator Freeze ThermostatAn SPST temperature−actuated switch that stops unitoperation when evaporator reaches freeze−up conditions.
Usage Guideline:
PRODUCT SPECIFICATIONS Horizontal Heat Pump: NH4H4
428 51 9702 00 15Specifications subject to change without notice.
Required when low ambient kit has been added.5. Isolation RelayAn SPDT relay that switches the low−ambient controller outfo the outdoor fan motor circuit when the heat pumpswitches to heating mode.
Usage Guideline:Required on all heat pumps where low−ambientkit has been added.
6. Liquid−Line Solenoid Valve (LLS)An electrically operated shutoff valve which stops and startsrefrigerant liquid flow in response to compressor operation. Itis to be installed at the outdoor unit to control refrigerant offcycle migration in the heating mode.
Usage Guideline:An LLS is required in all long line heat pumpapplications to control refrigerant off cycle
migration in the heating mode. See Long LineGuideline.
7. Low−Ambient Pressure Switch KitA long life pressure switch which is mounted to outdoor unitservice valve. It is designed to cycle the outdoor fan motor inorder to maintain head pressure within normal operatinglimits. The control will maintain working head pressure atlow−ambient temperatures down to 0�F (−18�C) whenproperly installed.
Usage Guideline:A Low−Ambient Pressure Switch Low−Ambient Controller must be used when
cooling operation is used at outdoortemperatures below 55�F (12.8�C).
Suggested for all commercial applications.
