Filter Drier

The filter drier is very important for proper system operation 

and  reliability.  If  the  drier  is  shipped  loose,  it  must  be 

installed by the installer in the field. Unit warranty will be 

void, if the drier is not installed.

Installation of Line Sets

DO NOT

 fasten liquid or suction lines in direct contact with 

the floor or ceiling joist. Use an insulated or suspension 

type  of  hanger.  Keep  both  lines  separate,  and  always 

insulate the suction line. Liquid line runs (30 feet or more) 

in  an  attic  will  require  insulation.  Route  refrigeration  line 

sets to minimize length.

DO NOT

 let refrigerant lines come in direct contact with 

foundation.  When  running  refrigerant  lines  through  the 

foundation  or  wall,  openings  should  allow  for  a  sound 

and vibration absorbing material to be placed or installed 

between  tubing  and  foundation.  Any  gap  between 

foundation or wall and refrigerant lines should be filled with 

a vibration damping material.

If ANY refrigerant tubing is required to be buried by state 

or local codes, provide a 6 inch vertical rise at service 

valve. 

 CAUTION

Flushing Line Sets

If the unit will be installed in an existing system that uses 

an indoor unit or line sets charged with R-22 refrigerant, 

installer must perform the following flushing procedure.

NOTE: 

Existing system components (including line set 

and indoor coil) must be an AHRI match with the unit in 

order to fulfill unit warranty requirements.

Refrigerant  must  be  reclaimed  in  accordance  with 

national and local codes.

 WARNING

Do 

NOT

 attempt to flush and re-use existing line sets 

or indoor coil when the system contains contaminants 

(i.e., compressor burn out).

 CAUTION

“Clean  refrigerant”  is  any  refrigerant  in  a  system  that 

has  not  had  compressor  burnout.  If  the  system  has 

experienced  burnout,  it  is  recommended  that  the 

existing line set and indoor coil be replaced.

NOTE

Refrigeration Piping

• 

Use only refrigerant grade copper tubes. 

• 

Split systems may be installed with up to 50 feet of 

line set (no more than 20 feet vertical) without special 

consideration (see long line set guidelines). 

• 

Ensure  that  vapor  and  liquid  tube  diameters  are 

appropriate to capacity of unit.

• 

Run  refrigerant  tubes  as  directly  as  possible  by 

avoiding unnecessary turns and bends.

• 

When passing refrigerant tubes through the wall, seal 

opening with RTV or other silicon-based caulk.

• 

Avoid direct tubing contact with water pipes, duct work, 

floor joists, wall studs, floors, walls, and any structure.

• 

Do  not  suspend  refrigerant  tubing  from  joists  and 

studs  with  a  rigid  wire  or  strap  that  comes  in  direct 

contact with tubing.

• 

Ensure that tubing insulation is pliable and completely 

surrounds vapor tube.

It is important that no tubing be cut or seals broken until you 

are ready to actually make connections to the evaporator 

and  to  the  condenser  section.  DO  NOT  remove  rubber 

plugs  or  copper  caps  from  the  tube  ends  until  ready  to 

make connections at evaporator and condenser. Under no 

circumstances leave the lines open to the atmosphere for 

any period of time, if so unit requires additional evacuation 

to remove moisture.

Table 3. Recommended Liquid & Vapor Tube 

Diameters (in.)

Be extra careful with sharp bends. Tubing can “kink” very 

easily, and if this occurs, the entire tube length will have 

to be replaced. Extra care at this time will eliminate future 

service problems.

It is recommended that vertical suction risers not be up-

sized.  Proper  oil  return  to  the  compressor  should  be 

maintained with suction gas velocity.
