SAFETY CONSIDERATIONS

Installation, service, and repair of these units should be attempted

only by trained service technicians familiar with standard service

instruction and training material.

All equipment should be installed in accordance with accepted

practices and unit Installation Instructions, and in compliance with

all national and local codes. Power should be turned off when

servicing or repairing electrical components. Extreme caution

should be observed when troubleshooting electrical components

with power on. Observe all warning notices posted on equipment

and in instructions or manuals.

UNIT OPERATION AND SAFETY HAZARD

Failure to follow this warning could result in personal

injury or equipment damage.

Puronr (R-- 410A) systems operate at higher pressures than

standard R -- 22 systems. Do not use R-- 22 service equipment

or components on Puronr equipment. Ensure service

equipment is rated for Puronr.

WARNING

Refrigeration systems contain refrigerant under pressure. Extreme

caution should be observed when handling refrigerants. Wear

safety glasses and gloves to prevent personal injury. During normal

system operations, some components are hot and can cause burns.

Rotating fan blades can cause personal injury. Appropriate safety

considerations are posted throughout this manual where potentially

dangerous techniques are addressed.

INTRODUCTION

This document provides required system information necessary to

install, service, repair or maintain the family air conditioners and

heat pumps using R22 or Puron refrigerant.

Refer to the unit Product Data for rating information, electrical

data, required clearances, additional component part numbers and

related pre--sale data. Installation Instructions are also available per

specific models.

Information in this document refers to units produced in 2006 and

later. For products produced prior to this date, please refer to

Service Manual number SM01,02-- 5 for products containing R22

refrigerant and Service Manual SM01 -- 4 for products containing

Puron refrigerant.

INSTALLATION GUIDELINE

Residential New Construction

Specifications for these units in the residential new construction

market require the outdoor unit, indoor unit, refrigerant tubing sets,

metering device, and filter drier listed in Product Data (PD). DO

NOT DEVIATE FROM PD. Consult unit Installation Instructions

for detailed information.

Add--On Replacement (Retrofit) -- R22 to Puron

Specifications for these units in the add--on replacement/retrofit

market require change-- out of outdoor unit, metering device, and

all capillary tube coils. Change--out of indoor coil is recommended.

There can be no deviation.

1. If system is being replaced due to compressor electrical

failure, assume acid is in system. If system is being replaced

for any other reason, use approved acid test kit to determine

acid level. If even low levels of acid are detected install

factory approved, 100 percent activated alumina

suction--line filter drier in addition to the factory supplied

liquid--line filter drier . Remove the suction line filter drier as

soon as possible, with a maximum of 72 hr.

2. Drain oil from low points or traps in suction-- line and

evaporator if they were not replaced.

3. Change out indoor coil or verify existing coil is listed in the

Product Data Digest.

4. Unless indoor unit is equipped with a Puronr approved

metering device, change out metering device to factory

supplied or field--accessory device specifically designed for

Puronr.

5. Replace outdoor unit with Puronr outdoor unit.

6. Install factory--supplied liquid--line filter drier.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment

damage or improper operation.

Never install suction--line filter drier in the liquid--line of a

Puronr system.

CAUTION

7. If suction--line filter drier was installed for system clean up,

operate system for 10 hr. Monitor pressure drop across drier.

If pressure drop exceeds 3 psig, replace suction--line and

liquid--line filter driers. Be sure to purge system with dry

nitrogen and evacuate when replacing filter driers. Continue

to monitor pressure drop across suction--line filter drier .

After 10 hr of runtime, remove suction--line filter drier and

replace liquid--line filter drier. Never leave suction--line

filter drier in system longer than 72 hr (actual time).

8. Charge system. (See unit information plate.)

Seacoast

Coastal units are available in selected models and sizes of Air

Conditioners and Heat Pumps. These units have protection to help

resist the corrosive coastal environment. Features include:

S Armor plate fins and epoxy coated coils

S Complete baked--on paint coverage

(both sides of external sheet metal and grilles)

S Paint coated screws

Coastal environments are considered to be within 5 miles of the

ocean. Salt water can be carried as far away as 5 miles from the

coast by means of sea spray, mist or fog. Line--of-- sight distance

from the ocean, prevailing wind direction, relative humidity,

wet/dry time, and coil temperatures will determine the severity of

corrosion potential in the coastal environment.
