This produ ct has been design ed an d manufact ured to meet Energy S tar criteria for energy efficiency when matched with appropriate coil components. However, proper refr igerant ch arge and proper air flow are cri tical to achieve rated capacity and efficiency. Installation of this product should follow all manufacturing refrigerant charging and air flow instructions. Failure to confirm

proper charge and air flow may reduce energy efficiency and shorten equ ipment life.

REFRIGERANT CHARGE ADJUSTMENTS

Liquid Line Size Puron Charge oz/ft (g/m)

3/8

5/16 0.40 (11.83)

1/4 0.27 (7.98)

(Factory charge for lineset = 9 oz / 266.16 g)

0.60 (17.74)

Units are factory charged for 15 ft (4.6 m) of 3/8” liquid line. The factory charge for 3/8” lineset 9 oz.(266.16 g). When using other length or diameter liquid lines, charge adjustments are required per the chart above.

Charging

Formula:

[(Lineset oz/ft x total length) – (factory charge for lineset)] = charge adjustment Example 1: System has 15 ft of line set using existing 1/4“ liquid line. What charge adjustment is required?

Formula: (.27 oz/ft x 15ft) – (9 oz) = (-4.95) oz. Net result is to remove 4.95 oz of refrigerant from the system

Example 2: System has 45 ft of existing 5/16” liquid line. What is the charge adjustment?

Formula: (.40 oz/ft. x 45ft) – (9 oz.) = 9 oz. Net result is to add 9 oz of refrigerant to the system

LONG LINE APPLICATIONS

An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.

For Air Conditioner systems, the chart below shows when an application is considered Long Line.

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.
