* Units are rated with 25 ft (7.6 m) of lineset length. See Vapor Line Sizing and Cooling Capacity Loss table when using other sizes and lengths of lineset.
Note : See unit Installation Instruction for proper installation.
{ See Liquid Line Sizing For Cooling Only Systems with R-410A Refrigerant tables.
VAPOR LINE SIZING AND COOLING CAPACITY LOSS
LONG LINE APPLICATION: An application is considered
”Long line” when the total equivalent tubing length exceeds 80 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 and system modifications for reliable system operation. The maximum 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 up to 80 ft. (24.38 m) when the outdoor unit is below the indoor unit. Refer to
Accessory Usage Guideline below for required accessories. See
Longline Application Guideline for required piping and system modifications. Also, refer to the table below for the vapor tube diameters based on the total 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 combinations are 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.

{ Total and sensible capacities are net capacities. Blower motor heat has been subtracted.
} Sensible capacities shown are based on 80 _ F (27 _ C) entering air at the indoor coil. For sensible capacities at other than 80 _ F (27 _ C), deduct 835 Btuh
(245 kW) per 1000 CFM (480 L/S) of indoor coil air for each degree below 80
_
F (27
_
C), or add 835 Btuh (245 kW) per 1000 CFM (480 L/S) of indoor coil air per degree above 80
_
F (27
_
C).
** System kw is total of indoor and outdoor unit kilowatts.
EWB — Entering Wet Bulb
NOTES :
1. Detailed cooling capacities are based on indoor and outdoor unit at the same elevation per AHRI standard 210/240-2008. If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
2. When the required data falls between the published data, interpolation may be performed. Extrapolation is not an acceptable practice.

* The Btuh heating capacity values shown are net integrated values from which the defrost effect has been subtracted. The Btuh heating from supplement heaters should be added to those values to obtain total system capacity.
{
The kW values include the compressor, outdoor fan motor, and indoor blower motor. The kW from supplement heaters should be added to these values to obtain total system kilowatts.
NOTE : When the required data falls between the published data, interpolation may be performed. Extrapolation is not an acceptable practice.

PRODUCT SPECIFICATIONS
Accessory Description and Usage (Listed Alphabetically)
Horizontal Heat Pump: NH4H4
1. Ball−Bearing Fan Motor
A fan motor with ball bearings which permits speed reduction while maintaining bearing lubrication.
2. Compressor Start Assist − Capacitor and Relay
Start capacitor and relay gives a “hard” boost to compressor motor at each start up.
Usage Guideline:
Required for reciprocating compressors in the following applications:
Long line
Low ambient cooling
Hard shut off expansion valve on indoor coil
Liquid line solenoid on indoor coil
Required for single−phase scroll compressors in the following applications:
Long line
Low ambient cooling
Suggested for all compressors in areas with a history of low voltage problems.
3. Crankcase Heater
An electric resistance heater which mounts to the base of the compressor to keep the lubricant warm during off cycles.
Improves compressor lubrication on restart and minimizes the 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 Thermostat
An SPST temperature−actuated switch that stops unit operation when evaporator reaches freeze−up conditions.
Usage Guideline:
Required when low ambient kit has been added.
5. Isolation Relay
An SPDT relay that switches the low−ambient controller out for the outdoor fan motor circuit when the heat pump switches to heating mode.
Usage Guideline:
Required on all heat pumps where low−ambient kit has been added.
6. Liquid−Line Solenoid Valve (LLS)
An electrically operated shutoff valve which stops and starts refrigerant liquid flow in response to compressor operation. It is to be installed at the outdoor unit to control refrigerant off cycle migration in the heating mode.
Usage Guideline:
An LLS is required in all long line heat pump applications to control refrigerant off cycle migration in the heating mode. See Long Line Guideline.
7. Low Pressure Switch Kit
Factory Installed added compressor protection against loss of refrigerant. It cuts out the system at 50 PSI and allows operation again at 95 PSI. Used for commercial or “harsh” environment applications for extra protection.
8. Time Delay Relay
Optional accessory for systems that do not have an integral blower time delay.
