SAFETY CONSIDERATIONS

Improper  installation,  adjustment,  alteration,  service,  maintenance,  or

use can cause explosion, fire, electrical shock, or other conditions which

may  cause  death,  personal  injury,  or  property  damage.  Consult  a

qualified  installer,  service  agency,  or  your  distributor  or  branch  for

information  or  assistance.  The  qualified  installer  or  agency  must  use

factory-authorized  kits  or  accessories  when  modifying  this  product.

Refer to the individual instructions packaged with the kits or accessories

when installing. 
Follow  all  safety  codes. Wear  safety  glasses,  protective  clothing,  and

work  gloves.  Use  quenching  cloth  for  brazing  operations.  Have  fire

extinguisher available. Read these instructions thoroughly and follow all

warnings  or  cautions  included  in  literature  and    attached  to  the  unit.

Consult  local  building  codes  and  current  editions  of  the  National

Electrical Code ( NEC ) NFPA 70.  In Canada, refer to current editions

of the Canadian electrical code CSA 22.1.

Recognize safety information. This is the safety-alert symbol  . When

you see this symbol on the unit and in instructions or manuals, be alert to

the  potential  for  personal  injury.    Understand  these  signal  words;

WARNING, and CAUTION. These words are used with the safety-alert

symbol.  WARNING  signifies  hazards  which  could  result  in  personal

injury  or  death.  CAUTION  is  used  to  identify  unsafe  practices  which

would result in minor personal injury or product and property damage.

NOTE  is  used  to  highlight  suggestions  which  will  result  in  enhanced

installation, reliability, or operation.

Inverter Cover

IMPORTANT: 

The inverter cover should NEVER be removed because

inverter components are not serviceable.  The  inverter can be removed

from unit with cover installed.

Installation Recommendations

In some cases noise in the living area has been traced to gas pulsations

from improper installation of equipment.

1. Locate  unit  away  from  windows,  patios,  decks,  etc.  where  unit

operation sound may disturb customer. 

2. In noise sensitive applications (such as bedrooms), when a lineset is

mounted to ceiling joists or floor joists, the outdoor unit must be

located at least 10 ft (3.05 m) away.  If this is not possible, create a

line set configuration with enough bends to provide 10 ft (3.05 m)

of total line set length outside the dwelling

3. Ensure that vapor and liquid tube diameters are appropriate for unit

capacity. 

4. Run  refrigerant  tubes  as  directly  as  possible  by  avoiding

unnecessary turns and bends.

5. Leave some slack between structure and unit to absorb vibration.
6. When passing refrigerant tubes through the wall, seal opening with

RTV or other pliable silicon-based caulk (see 

Fig. 1

).

7. Avoid  direct  tubing  contact  with  water  pipes,  duct  work,  floor

joists, wall studs, floors, and walls. 

8. Do not suspend refrigerant tubing from joists and studs with a rigid

wire or strap which comes in direct contact with tubing (see 

Fig. 1

).

9. Ensure  that tubing insulation is pliable and completely surrounds

vapor tube.

10. When  necessary,  use  hanger  straps  which  are  1  in.  wide  and

conform to shape of tubing insulation. (See 

Fig. 1

.)

11. Isolate hanger straps from insulation by using metal sleeves bent to

conform to shape of insulation. 

WARNING

!

EXPLOSION HAZARD

Failure  to  follow  this  warning  could  result  in

death, serious personal injury, and/or property

damage.

Never  use  air  or  gases  containing  oxygen  for

leak  testing  or  operating  refrigerant

compressors.    Pressurized  mixtures  of  air  or

gases  containing  oxygen  can  lead  to  an

explosion.

CAUTION

!

CUT HAZARD

Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and wear

appropriate protective clothing and gloves when handling parts.

WARNING

!

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Before  installing,  modifying,  or  servicing  system,  main  electrical

disconnect switch must be in the OFF position. There may be more than

1 disconnect switch. Lock out and tag switch with a suitable warning

label. 

WARNING

!

ELECTRICAL HAZARD - HIGH VOLTAGE!

Failure to follow this warning could result in personal injury or death.

Electrical components may hold charge.  

DO NOT

 remove control box

cover for 2 minutes after power has been removed from unit.

PRIOR TO TOUCHING ELECTRICAL COMPONENTS:

Verify zero (0)voltage at inverter connections shown on inverter cover.

WARNING

!

UNIT OPERATION AND SAFETY HAZARD

Failure to follow this warning could result in personal injury

or equipment damage.
