General Information
More cost-effective refrigerant-loop service kits are now available for both sealed-unit and split-unit ParkSmart
systems. A service kit must be used to repair units with failed components that are part of the soldered refrigerant loop. In most cases, replacing the entire ParkSmart unit is no longer a warrantable repair option. Figure 1
shows the sealed-unit service kit with the case open. The split-unit is similar but does not have the condenser in
it.

for clarity—split unit similar)

Sealed Unit Change Information
For units manufactured before July 2011, the kit includes the sealed refrigerant loop in a new redesigned case.
The new case has improved condensate drainage and an access panel for compressor testing. See Table 1 for
sealed unit replacement parts. When using this kit, it is necessary to transfer the following components from the
original unit to the new one:
• main harness
• heater core
• blower motor assembly
• blend door
• blend door actuator
• controller and harness (if not being replaced)
• temperature sensors
• foam strip from the top of the condenser

Sealed Unit Service Kit Installation
NOTE: When installing the main harness, it may not wrap around the case exactly the way it did on
the early model case due to design changes. This is not a problem, as there is adequate clearance in
the cabinet.
1. Park the vehicle on a level surface, shut down the engine and set the parking brakes. Chock the tires.
2. Disconnect the starting batteries at the negative post.
3. Disconnect the auxiliary batteries at the negative post.

NOTICE
Do not attempt to remove the new refrigerant loop from the new case that it is shipped in. Doing so will
damage the refrigerant loop and render the part useless.
4. Remove the ParkSmart from the vehicle. For instructions, refer to Subject 83.03, 120 of the Cascadia
Workshop Manual.
5. On the workbench, transfer all of the removable parts from the original unit to the new case containing the
new refrigerant loop. For instructions on removing and installing individual parts, refer to Section 83.03 of
the Cascadia Workshop Manual.
6. Install the new ParkSmart in the vehicle. For instructions refer to Subject 83.03, 120 of the Cascadia Workshop Manual.

Split Unit Change Information
For ParkSmart units built from July 2011, the kit includes the non-repairable refrigerant loop in a new case with
sealed connections for the external refrigerant lines. In some cases, a new wiring harness and internal controller
are also needed. See Table 2. When using this kit, it is necessary to transfer the following components from the
original unit to the new case:
• main harness
• heater core
• blower motor assembly
• blend door
• blend door actuator
• controller and harness (if not being replaced)
• temperature sensors
Follow the instructions in Section 83.03 of the Cascadia Workshop Manual when removing and installing individual components.

WARNING
The ParkSmart system uses a non-conductive compressor oil. Use only polyvinylether (PVE) refrigerant
oil in this system. The refrigerant system has enough oil capacity to be recovered four times over the
life of the unit. Oil should never need to be added, but if it does, the correct type must be used to prevent a dangerous electrical short from occurring in the compressor. When handling this oil, observe the
following guidelines.
• Keep the oil free of contaminants.
• Do not expose the air conditioning system or the oil container to air for more than five minutes. The oil
has a high moisture absorption capacity and the oil container should be sealed immediately after each
use.
• Use care when handling. Spilled oil could damage painted surfaces, plastic parts, and other components
such as drive belts.
• Never mix PVE oil with other types of refrigerant oil.
Failure to follow these guidelines could lead to component damage or severe electrical shock to anyone
touching the system components.
1. Park the vehicle on a level surface, shut down the engine and set the parking brakes. Chock the tires.

NOTE: The ParkSmart has only one charging port. Use the high-side hose from the charging machine
to service the system.
2. Recover the refrigerant from the system as follows.
2.1

Remove the cap form the service port at the back of the sleeper.

2.2

Identify the refrigerant using the "Refrigerant Identification" procedures listed in Subject 83.03, 250
of the Cascadia Workshop Manual.

IMPORTANT: Push down firmly on the hose connectors until a clicking sound is heard. This will
ensure that the coupler is locked.
2.3

Wearing protective goggles and nonleather gloves, attach the refrigerant recovery and charging machine hose to service port.

2.4

Follow the refrigerant recovery and charging machine manufacturer’s instructions, and recover all of
the refrigerant from the refrigerant system.

IMPORTANT: Always comply with all federal and local regulations regarding refrigerant recovery
and disposal. You may be subject to substantial penalties for improper procedures.
3. Disconnect the starting batteries at the negative post.
4. Disconnect the auxiliary batteries at the negative post.

NOTICE
Do not attempt to remove the new refrigerant loop from the new case that it is shipped in. Doing so may
damage the refrigerant loop and render the part useless.
5. Remove the ParkSmart from the vehicle. For instructions refer to Subject 83.03, 120 of the Cascadia Workshop Manual.

6. On the workbench, transfer all of the removable parts from the original unit to the new case containing the
new refrigerant loop. For instructions on removing and installing individual parts, refer to Section 83.03 of
the Cascadia Workshop Manual.
7. Install the new ParkSmart unit in the vehicle. For instructions refer to Subject 83.03, 120 of the Cascadia
Workshop Manual.
8. Evacuate and charge the system as follows.
8.1

Make sure the vacuum pump has been properly maintained.

8.2

Attach the refrigerant recovery and charging machine hose, or a vacuum pump, to the valve.

IMPORTANT: Push down firmly on the hose connector until a clicking sound is heard. This will
ensure that the coupler is locked.
8.3

Follow the refrigerant recovery and charging machine manufacturer’s instructions, and evacuate the
refrigerant system.

8.4

Using a 6-cfm pump, the system should be evacuated for a minimum of 10 minutes. Evacuate the
system for a longer period of time if using a smaller pump. Make sure that the vacuum level reaches
a point where water would boil and does not go back toward zero, then proceed with charging and
leak testing the system

NOTE: The correct charge for the vehicle is shown on the sticker near the charging port.
8.5

Charge the system on the high side following the refrigerant recovery and charging machine manufacturer’s instructions.

8.6

Start the ParkSmart system and use the information in C02.01 of the Cascadia Troubleshooting
Manual to evaluate the system performance.

8.7

Disconnect the hose.

8.8

Recover the refrigerant that is in the hose.
