Refrigerant Piping Guidelines

Refrigerant Piping Procedures
(Outdoor units)

Each TTA unit ships with dry nitrogen 
holding charge. Due to this minimal 
amount, we recommend that it be 
removed and the entire system 
evacuated (at the proper time) to avoid 
possible contamination. 
1. Remove the compressor service

access panel.

2. Locate the liquid and suction line

service valves. Check that the
piping connection stubs on the
valves (Figure 1) line up properly
with the holes in the unit cabinet.

3. Front-seat (close) both of the

service valves must be closed
before the system is opened.

puncturing the seal caps on the
connection stubs. If the seal caps are
punctured with the valves open, the
refrigerant contained in each circuit
will be lost.

unless they have been punctured. If
caps are intact, application of heat
may generate excessive pressure in
the connection stub, causing personal
injury or death due to rupturing of
components and damage to the
service valve.

4. Heat and remove the seal caps.

moisture or dirt to contaminate the

causing ice formation in system

6. Shut off nitrogen supply.
7. Shut off  the manifold valve for

Refrigerant Piping Procedure
(Indoor Unit)

Once liquid and suction lines are
complete to the refrigerant
connections on the indoor unit, heat
and remove the seal caps on the
indoor unit connection stubs to
release the dry nitrogen charge.

Caution:

 Install a regulating valve

Caution:

 Wet-wrap all valves and

1. Remove both seal caps from the

indoor unit connection stubs.

2. Turn nitrogen supply on. Nitrogen

enters through the liquid line
gauge port.

3. Braze the liquid line connections.
4. Open the gauge port on the suction

line and then braze suction line to
the connection stub. Nitrogen will
bleed out the open gauge port on
the suction line.

5. Shut off nitrogen supply.

Leak Check

After the brazing operation of
refrigerant lines to both the outdoor

brazed connections must be checked
for leaks. Pressurize the system
through the service valve with dry
nitrogen to 400 psi. Use soap bubbles
or other leak-checking methods to

LUZ\YL[OH[HSSÄLSKQVPU[ZHYLSLHRMYLL

If not, release pressure, repair and
repeat leak test.

Caution:

 Do not remove seal caps 

until prepared to braze refrigerant lines 
to the connections. Extended exposure 
to atmosphere may allow moisture or 
dirt to contaminate the system, 
damaging system components.
