Introduction 0-3
Congratulations!
You have chosen the premier no-idle climate control system on the market today –the
eCoolPark 1.0 from Bergstrom Inc.
The eCoolPark 1.0 is a powerful 12 VDC system that keeps the cab compartment cool in hot
weather without having to idle the vehicle engine. This system is intended to provide no-idle
cooling for the cab. The system consists of an electrified compressor unit installed in the
trunk of the vehicle. The system integrates into the existing A/C hoses/tubes and utilizes the
existing evaporator and condenser. Check valves are used to isolate the eCoolPark system
from the OEM refrigeration system. It not only dramatically reduces fuel burned, but is also
extremely environmentally friendly.
The eCoolPark unit must remain upright at all times. The refrigerant inlet/outlet
at the bottom of the unit should be capped at all times.

Precautions for working with HFC134a
(R134a) Refrigerant and Polyalkylene Glycol
(PAG) Refrigerant Oil
Warning
•Do no breath A/C refrigerant, oil vapor, or mist.
Exposure may cause irritation to the eyes, nose,
and throat.
•Instances where there are accidental system
discharges; ventilate work area before resuming
service.
•For additional health and safety information,
contact the refrigerant and oil manufacturers.
Caution
•The air conditioning system uses HFC134a
(R134a) refrigerant and polyalkylene glycol
(PAG) refrigerant oil, which are not
compatible with CFC-12 (R12) refrigerant,
mineral oil, or PVE oil. If the refrigerants or
oils are mixed, the compressor may fail.
•Do not attempt to use R-12 servicing equipment.
Failure to follow this statement may result in
personal injury or equipment damages.
•Use service equipment that is only U.L listed and
certified in which meets the required standards of
SAE J2210 to remove HFC134a (R134a) from
the air condition system.
•Before testing, please authenticate the HFC134a
(R134a) refrigerant in the vehicle system and
recycling equipment / recovery tank are
contaminate free by using a refrigerant identifier.
Note
The air conditioning system is designed only for certain
polyalkylene glycol (PAG) refrigerant oil for HFC134a (R134a)
A/C systems and HFC134a (R134a) components. The only
recommended oil for this particular system is PAG oil (PAG 46,
100, and 150). The PAG oil is very hygroscopic, meaning it absorbs
water. Without appropriate sealing, the oil will become moisture
saturated and should not be used.

•When handling corrosion inhibitors and lubricating
oils avoid exposure to eyes and repeated contact to
skin for they may contain alkali. In case of contact,
immediately wash skin with soap and water. When
cases are severe, please contact a physician. Store
toxic products and substances out of reach of children.
•Naptha and Methyl Ethyl Ketone (MEK) are
flammable and hazardous materials and must be used
with attentiveness. Follow manufacture guidelines to
ensure safety when handling materials. Store toxic
products and substances out of reach of children.
•When operating on a vehicle be attentive and cautious
for hot parts on systems that have been turned off,
exhaust gas flow, and hot fluids in lines, tubs, and
compartments. Direct contact to skin may cause
severe burns.
•Always use tools that are in good working condition.
Service technicians must be trained and have proper
understanding on how to use the tools before
administering service.
•When replacing items use the same and/or equivalent
fastener part number at all times. Conversely, do not
use a fastener of reduced quality if replacement is
needed.
•To prevent bodily injury or harm do not perform any
repairs when impaired, fatigued or after consuming
alcohol or drugs that can impair one’s functioning.
•According to several states and federal agencies
within the United States of America it has been
evident that used engine oil can be carcinogenic,
causing reproductive toxicity. That being said, avoid
inhalation of vapors, ingestion, and prolonged contact
with used engine oil.
•Be mindful that liquefied petroleum gas is denser than
air and can accumulate near the floor, in slumps, and
low-lying area.
•Close the manual fuel valves prior to performing
maintenance and repairs and when storing the vehicle
inside.
•California Proposition 65 Warning –Diesel engine
exhaust and some of its constituents are known to the
state of California to cause cancer, birth defects, and
other reproductive harm. To request more information
regarding the chemical exposures that are the basis of
the warning, contact the manufacture of the product.

Installation Procedures 1-2
The installation of this no-idle A/C system is done in several parts:
•The eCoolPark 1.0 unit includes a compressor, an ECU (electric control
unit), and a cooling fan. It is installed in the trunk of the vehicle.
•The OEM refrigerant lines of the vehicle are altered using “T” fittings and
hoses are run from the T’s to the eCoolPark unit.
•Electrical harnesses are routed between the eCoolPark unit, power source,
and driver compartment. Additionally, a harness is routed to jump in-
between the OEM condenser harness.
It is important that the technician completing this installation read through this
manual and plan out the steps forthcoming. Certain mistakes like cutting
hoses to short or drilling into refrigerant hoses can cause long installation
delays and/or component damage.
Hose Routing Preview
The following steps will provide a description of the procedure outlined above
in detail.
PLEASE READ!

Installation Procedures 1-3
1. Disconnect Power Source and Reclaim OEM Refrigerant
a. Disconnect the desired power source for the duration of the install. The vehicle main start battery
can remain connected.
b. Reclaim the existing refrigerant in the OEM system using a refrigerant machine or refrigerant
reclamation components.
c. Reclamation should be done by a Section 609 certified technician.
d. If a Robinair or refrigerant machine equivalent is not available, components needed include an
R-134a or R-1234yf recovery machine, a recovery tank, and a gauge set with SAE hoses.

Figure 1.7: Bolts that require removal

Installation Procedures 1-5
3. Run Hoses (loose)
a. Locate the position where the hoses will exit the interior of the vehicle (marked with X in figure
1.4).
b. Verify the opening is large enough for both hose fittings. If not, use an air saw to enlarge the
hole. Before drilling check for obstruction under the vehicle.
c. Locate the 2 different sized hoses in the kit and wrap the entirety of each hose separately with
heat shield tape (figure 1.9). Leave 1 foot of un-taped hose on each end. Tape the ends of the
hoses with masking or painters tape to avoid contamination.
d. Route the hoses from the unit, under the vehicle, over to the passenger side, and into the engine
bay. Securely zip tie the hoses to the existing A/C lines and leave the ends loose for now. Be
sure no hoses are rubbing against rough or sharp surfaces.
e. The hoses should be wrapped in heat shield tape completely in-between the unit and engine bay.
f. Vehicle technicians should identify the best way to route these hoses. Stay away from hot
components such as exhaust.

4. Identify OEM Refrigerant Tubing/Hoses and Install T Fittings
a. Take a minute to study the schematic shown in figure 1.11. Note the T locations in which the
eCoolPark system uses to access the OEM refrigerant system.
b. Identify the refrigerant lines where the T’s will be inserted. These will be the compressor
discharge line (compressor to condenser) and the compressor suction line (TXV to compressor).
c. Confirm that the hose in the suction and discharge section of OEM hose is suitable for the
fittings provided in the Bergstrom kit. Hose should be Galaxy 4890 ¾ in. and 13/32 in. If not
labeled, measure the ID and OD and consult figure 1.16.
d. Assemble the discharge T and check valves per page 1-7. Remove the OEM discharge line by
loosening the nuts on the compressor and condenser connections. The OEM suction line can
stay inserted in the vehicle. Mockup the suction 14-14-8 T on the suction line (figure 1.12). The
discharge line will have a T hose fitting inserted in the hose section of the discharge line (figure
1.13).
The arrows on the check valves must point in the direction of flow
