Connecting the Linesets

1. Route and cut both lineset tubes to proper length in 

accordance with the outdoor unit specifications. Verify 

the ends are round, clean, and free of any burrs.

2. Cut off the fitting on the 3/8” line of the coil. Swage as 

needed to fit the line set.

3. Connect the suction and liquid lineset tubes.

 CAUTION:

It is recommended that a wet rag be wrapped 
around the suction line in front of the close 
off plate before applying heat. Failure to keep 
components cool during brazing may result 
in structural damage, premature equipment 
failure, or possible personal injury.

4. Braze the individual connections with dry nitrogen 

flowing through the joints. This will prevent internal 

oxidation and scaling from occurring.

IMPORTANT: To prevent internal oxidation and scaling 

from occuring, braze all connections with dry nitrogen 

flowing through the joints.

5. Wrap the refrigerant lines with pressure sensitive 

neoprene or other suitable material especially where 

the lines enter the opening in the sheet metal.

6. Evacuate the system of moisture and non-condensables 

to prevent low efficiency operation or damage to the 

unit. The suggested range of evacuation is 250 - 500 

microns.

7. Charge the system with refrigerant. 

Please Refer to 

the outdoor unit installation manual for additional 

charging instructions

.

8. Check the system for leaks, including the lineset and 

the brazed joints.

 NOTE:

 Apply a soap and water solution on each joint or 

union with a small paintbrush. If bubbling is observed, 

the connection is not adequately sealed.

9. Properly dispose of all removed parts.

Condensate Drain

 CAUTION:

The coil must be level to ensure proper 
condensate drainage. Improper condensate 
disposal may result in structural damage, 
premature equipment failure, or possible 
personal injury.

•  Methods for disposing of condensate vary according 

to local codes. Refer to local codes or authority having 

jurisidiction for restrictions and proper condensate 

disposal requirements.

•  All condensate pans have primary and secondary drain 

connections to meet FHA requirements. If the application 

is located in or above a living space where damage 

may result from condensate overflow, a separate 3/4 

inch drain must be provided from the secondary drain 

connection and a secondary drain pan must be installed 

under the entire unit. Run secondary drain lines to a 

place where they are noticeable if used.

• The coil condensate pan is designed with 3/4” 

NPSC drain connections. Use a PVC or similar 

material fitting to attach the drain line to the pan.  

NOTE:

 The fitting should be hand tightened only. 

Overtightening may crack the drain pan and cause 

condensate to leak.

•  The drain pan MUST be drained with field supplied 

tubing and looped to form a trap.

 IMPORTANT:

 

Failure to install a trap may result in 

condensation overflowing the drain pan, resulting 

in substantial water damage to surrounding area.

•  Prime the trap with water. Insulate the drain if it is located 

in an unconditioned space, and test the condensate line 

for leaks. Consult local codes for additional restrictions 

or precautions.

•  Route the lines to a suitable drain, avoiding sharp bends 

and pinching of the lines. The drain should maintain a 

minimum horizontal slope in the direction of discharge 

of not less than 1” vertical for every 10 ft of horizontal 

run.

• During system checkout, inspect the drain line and 

connections to verify proper condensate drainage.
