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.
