* For tubing set lengths between 80 and 200 ft. (24.38 and 60.96 m) horizontal or 35 ft. (10.7 m) vertical differential (total equivalent length), refer to the Long
Line Guideline—Air Conditioners and Heat Pumps using Puron® Refrigerant.
{ Required on all indoor units. Standard on all new Puron refrigerant fan coils and furnace coils.
Accessory Description and Usage (Listed Alphabetically)
1. Compressor Start Assist - - Capacitor and Relay
Start capacitor and relay gives a "hard" boost to compressor
motor at each start up.
Usage Guideline:
Not required on this unit since compressor always starts
unloaded.
Available if required by local codes.
2. 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.

3. Support Feet
Four stick- -on plastic feet that raise the unit 4 in. (101.6 mm)
above the mounting pad. This allows sand, dirt, and other debris
to be flushed from the unit base, minimizing corrosion.
Usage Guideline:
Suggested in the following applications:
Coastal installations.
Windy areas or where debris is normally circulating.
Rooftop installations.
For improved sound ratings.
4. Thermostatic Expansion Valve (TXV)
A modulating flow- -control valve which meters refrigerant liquid
flow rate into the evaporator in response to the superheat of the
refrigerant gas leaving the evaporator.
Kit includes valve, adapter tubes, and external equalizer tube.
Hard shut off types are available.
NOTE: When using a hard shut off TXV with single phase
reciprocating compressors, a Compressor Start Assist Capacitor
and Relay is required.
Usage Guideline:
Required to achieve AHRI ratings in certain equipment
combinations. Refer to combination ratings.
Hard shut off TXV or LLS required in air conditioner
long line applications.
