Component Matches
Check to see that you have the proper system compo-
nents. APPROVED MATCHED SYSTEM COMPONENTS
MUST BE USED. Refer to the Sales Specification Sheet
or Split System Summary for match data and orifice
sizes.
The outdoor units are shipped with a refrigerant charge to
match the indoor unit and 25 ft. (7.5m) of refrigerant line. If
shorter or longer lines are used, the charge will have to be
adjusted.
OUR STANDARD RECOMMENDED REFRIGERANT
LINE LENGTH IS 75 ft. WITH A MAXIMUM VERTICAL
SEPARATION OF 50ft. BETWEEN THE OUTDOOR AND
INDOOR UNITS WITH 3TRAPS, 2 TRAPS FOR 40 FOOT
RISE. LONGER REFRIGERANT LINES CAN BE
INSTALLED BY USING THE EXTENDED LENGTH RE-

DEPARTMENT.
Restrictor Orifice
Some indoor matches use a restrictor orifice in the fitting at
the indoor coil. Some matches may require a different ori-
fice for proper system performance and it must be changed
before the refrigerant lines are connected.
Changing the Restrictor Orifice
The restrictor orifice is located in a fitting in the liquid line.
The fitting is actually the distributor end of the cap tube as-
sembly.
1. Remove the liquid line fitting and replace restrictor ori-
fice. (STANDARD RIGHT HAND THREAD)
2. Make sure the restrictor is installed with the rounded
end toward the feeder tubes. See Figure 3.

Refrigeration Line Sets
If it is necessary to add tubing in the field, use dehydrated or
dry sealed deoxidized copper refrigeration tube. DO NOT
use copper water pipe.
It is important that no tubing is 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 evapora-
tor and condenser.
PLEASE! UNDER NO CIRCUMSTANCES LEAVE THE
LINES OPEN TO THE ATMOSPHERE FOR ANY
PERIOD OF TIME.
Be extra careful with sharp bends. This 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.
Suspension And Installation Of
Refrigeration Lines
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 insulate the
suction line. Both lines should be insulated in extremely
long runs in an attic or underground in a raceway, 50' or
more.
