5. Operating Gauge Set and Service Valves
These instructions are intended as a general guide and do not supersede local codes in any
way. Consult authorities who have jurisdiction before installation.
5.1 Torque Requirements
When servicing or repairing heating, ventilating, and air conditioning components, ensure the
fasteners are appropriately tightened. Table 4 lists torque values for fasteners.
IMPORTANT
Only use Allen wrenches of sufcient hardness (50Rc −Rockwell Harness Scale minimum).
Fully insert the wrench into the valve stem recess.
Service valve stems are factory−torqued (from 9 ft−lbs for small
valves, to 25 ft−lbs for large valves) to prevent refrigerant loss during shipping and handling.
Using an Allen wrench rated at less than 50Rc risks rounding or breaking off the wrench, or
stripping the valve stem recess.
To prevent stripping of the various caps used, the appropriately sized wrench should be used
and tted snugly over the cap before tightening.
Table 4. Torque Requirements
Parts Recommended Torque
Service valve cap 8 ft.− lb. 11 NM
Sheet metal screws 16 in.− .lb 2 NM
Machine screws #10 28 in.− lb. 3 NM
Compressor bolts 90 in.− lb. 10 NM
Gauge port seal cap 8 ft.− lb. 11 NM
5.2 Using Manifold Gauge Set
When checking the system charge, only use a manifold gauge set that features low loss anti−
blow back ttings.
Manifold gauge set used with HFC−410A refrigerant systems must be capable of handling the
higher system operating pressures. The gauges should be rated for use with pressures of 0 − 800
psig on the high side and a low side of 30" vacuum to 250 psig with dampened speed to 500 psig.
Gauge hoses must be rated for use at up to 800 psig of pressure with a 4000 psig burst rating.
5.3 Operating Service Valves
The liquid and vapor line service valves are used for removing refrigerant, ushing, leak testing,
evacuating, checking charge and charging.
Each valve is equipped with a service port which has a factory−installed valve stem. Figure 11
provides information on how to access and operating both angle service valves.
5.4 Operating Angle Type Service Valve
1). Remove stem cap with an appropriately sized wrench.
2). Use a service wrench with a hex−head extension (3/16" for liquid line valve sizes and 5/16"
for vapor line valve sizes) to back the stem out counterclockwise as far as it will go.

5.5 To Access Service Port
A service port cap protects the service port core from contamination and
serves as the primary leak seal.
1). Remove service port cap with an appropriately sized wrench.
2). Connect gauge set to service port.
3). When testing is completed, replace service port cap and tighten as follows
● With torque wrench: Finger tighten and torque cap per table 4.
● Without torque wrench: Finger tighten and use an appropriately sized
wrench to turn an additional 1/6 turn clockwise.
5.6 Reinstall Stem Cap
Stem cap protects the valve stem from damage and serves as the primary
seal. Replace the stem cap and tighten as follows:
● With Torque Wrench: Finger tighten and then torque cap per table 4.
● Without Torque Wrench: Finger tighten and use an appropriately sized
wrench to turn an additional 1/12 turn clockwise.
NOTE: A label with specific torque requirements may be affixed to the
stem cap. If the label is present, use the specied torque.
5.7 Install Liquid Line Filter Drier Indoor
Refer to Fig. 12 and install lter drier as follows:
1). Braze 5 in. liquid tube to the indoor coil.
2). Wrap lter drier with damp cloth.
3). Braze lter drier to 5 in. long liquid tube from step 1.
4). Connect and braze liquid refrigerant tube to the lter drier.

6.3 Recovering Refrigerant
Remove existing HCFC−410A refrigerant using one of the following procedures:
METHOD 1:
Us this method if the existing outdoor unit is not equipped with shut−off valves, or if the unit is
not operational and you plan to use the existing HCFC−410A to ush the system.
Remove all HCFC−410A refrigerant from the existing system. Check gauges after shutdown to
conrm that the entire system is completely void of refrigerant.
METHOD 2:
Use this method if the existing outdoor unit is equipped with manual shut−off valves, and you
plan to use new HCFC−410A refrigerant to ush the system.
The following devices could prevent full system charge recovery into the outdoor unit:
● Outdoor unit’s high or low−pressure switches (if applicable) when tripped can cycle the
compressor OFF.
● Compressor can stop pumping due to tripped internal pressure relief valve.
● Compressor has internal vacuum protection that is designed to unload the scrolls
(compressor stops pumping) when the pressure ratio meets a certain value or when the suction
pressure is as high as 20 psig. (Compressor suction pressures should never be allowed to go into
a vacuum. Prolonged operation at low suction pressures will result in overheating of the scrolls and
permanent damage to the scroll tips, drive bearings and internal seals.)
Once the compressor can not pump down to a lower pressure due to one of the above system
conditions, shut off the vapor valve. Turn OFF the main power to unit and use a recovery machine
to recover any refrigerant left in the indoor coil and line set.
For more details visit www.MrCool.com

Unitary Ducted Split AC & HP
13
Perform the following task:
a. Start the existing HCFC−410A system in the cooling mode and close the liquid line valve.
b. Use the compressor to pump as much of the existing HCFC−410A refrigerant into the
outdoor unit until the outdoor system is full. Turn the outdoor unit main power OFF and use
a recovery machine to remove the remaining refrigerant from the system.
NOTE: It may be necessary to bypass the low pressure switches (if equipped) to ensure
complete refrigerant evacuation.
c. When the low side system pressures reach 0 psig, close the vapor line valve.
d. Check gauges after shutdown to conrm that the valves are not allowing refrigerant to ow
back into the low side of the system.
6.4 Leak Test Line Set and Indoor Coil
Fig.14—Leak Test
6.4.1 Connect Gauge Set
1). Connect an HFC−410A manifold gauge set high pressure hose to the vapor valve service
port.
NOTE: Normally, the high pressure hose is connected to the liquid line port. However,
connecting it to the vapor port better protects the manifold gauge set from high pressure damage.
2). With both manifold valves closed, connect the cylinder of HFC−410A refrigerant to the center
port of the manifold gauge set.
NOTE: Later in the procedure, the HFC−410A container will be replaced by the nitrogen
container.
6.4.2 Test For Leaks
After the line set has been connected to the indoor and outdoor units, check the line set
connections and indoor unit for leaks. Use the following procedure to test for leaks:
1). With both manifold valves closed, connect the cylinder of HFC−410A refrigerant to the center
For more details visit www.MrCool.com

Unitary Ducted Split AC & HP
14
port of the manifold gauge set. Open the valve on the HFC−410A cylinder (vapor only).
2). Open the high pressure side of the manifold to allow HFC−410A into the line set and indoor
unit. Weigh in a trace amount of HFC−410A. [A trace amount is a maximum of two ounces
(57 g) refrigerant or three pounds (31 kPa) pressure]. Close the valve on the HFC−410A
cylinder and the valve on the high pressure side of the manifold gauge set. Disconnect the
HFC−410A cylinder.
3). Connect a cylinder of dry nitrogen with a pressure regulating valve to the center port of the
manifold gauge set.
4). Adjust dry nitrogen pressure to 150 psig (1034 kPa). Open the valve on the high side of the
manifold gauge set in order to pressurize the line set and the indoor unit.
5). After a few minutes, open one of the service valve ports and verify that the refrigerant added
to the system earlier is measurable with a leak detector.
6). After leak testing disconnect gauges from service ports.
6.5 Evacuating Line Set and Indoor Coil
Fig.15—Evacuating System
6.5.1 Connect Gauge Set
NOTE : Remove cores from service valves (if not already done).
1). Connect low side of manifold gauge set with 1/4 SAE in−line tee to vapor line service valve
2). Connect high side of manifold gauge set to liquid line service valve
3). Connect micron gauge available connector on the 1/4 SAE in−line tee.
4). Connect the vacuum pump (with vacuum gauge) to the center port of the manifold gauge set.
The center port line will be used later for both the HFC−410A and nitrogen containers.
6.5.2 Connect Gauge Set
1). Open both manifold valves and start the vacuum pump.
2). Evacuate the line set and indoor unit to an absolute pressure of 23,000 microns (29.01
inches of mercury).
NOTE : During the early stages of evacuation, it is desirable to close the manifold gauge valve
at least once. A rapid rise in pressure indicates a relatively large leak. If this occurs, repeat the leak

testing procedure.
NOTE: The term absolute pressure means the total actual pressure within a given volume
or system, above the absolute zero of pressure. Absolute pressure in a vacuum is equal to
atmospheric pressure minus vacuum pressure.
3). When the absolute pressure reaches 23,000 microns (29.01 inches of mercury), perform the
following:
● Close manifold gauge valves
● Close valve on vacuum pump
● Turn off vacuum pump
● Disconnect manifold gauge center port hose from vacuum pump
● Attach manifold center port hose to a dry nitrogen cylinder with pressure regulator set to 150
psig (1034 kPa) and purge the hose.
● Open manifold gauge valves to break the vacuum in the line set and indoor unit.
● Close manifold gauge valves.
4). Shut off the dry nitrogen cylinder and remove the manifold gauge hose from the cylinder.
Open the manifold gauge valves to release the dry nitrogen from the line set and indoor unit.
5). Reconnect the manifold gauge to the vacuum pump, turn the pump on, and continue to
evacuate the line set and indoor unit until the absolute pressure does not rise above 500
microns (29.9 inches of mercury) within a 20−minute period after shutting off the vacuum
pump and closing the manifold gauge valves.
6). When the absolute pressure requirement above has been met, disconnect the manifold hose
from the vacuum pump and connect it to an upright cylinder of HFC−410A refrigerant. Open
the manifold gauge valve 1 to 2 psig in order to release the vacuum in the line set and indoor
unit.
7). Perform the following:
● Close manifold gauge valves.
● Shut off HFC−410A cylinder.
● Reinstall service valve cores by removing manifold hose from service valve.
Quickly install cores with core tool while maintaining a positive system pressure.
● Replace stem caps and secure nger tight, then tighten an additional one−sixth (1/6) of a turn
as illustrated.
