MANUAL OVERVIEW
This manual covers the topics of installation, operation, general
maintenance and troubleshooting for the HP2000 and the HP2000 Xtreme
Series APU by Parks Industries. The patented design of the HP2000 and the
HP2000 Xtreme’s unique features set it apart from any other unit currently
available on the market today. It provides solutions to many of the
problems faced by the transportation industry on a daily basis, yet reduces
the overall costs.

SAFETY
NOTE, IMPORTANT, WARNING, and CAUTION are used in this manual to emphasize important and critical
instructions.
Tips and safety warnings are listed throughout this manual. These tips and safety warnings alone cannot
eliminate all hazards that can occur. Pay close attention to instructions and use common knowledge during
maintenance procedures to prevent unnecessary accidents and injuries.
13 | Page
THIS SYMBOL IS USED TO CALL YOUR ATTENTION TO SAFETY PRECAUTIONS
THAT SHOULD BE FOLLOWED BY THE OPERATOR AND MAINTENANCE
PERSONNEL TO AVOID CARELESS ACCIDENTS. WHEN YOU SEE THIS SYMBOL
BE SURE TO OBSERVE AND FOLLOW THESE PRECAUTIONS. BE CERTAIN
THAT ANYONE OPERATING THIS MACHINE IS AWARE OF THESE SAFETY
RULES.

Follow all safety precautions listed below:
●Read this manual to familiarize yourself with the HP2000 APU. Performing maintenance on
unaccustomed machines can cause accidents.
●Wear proper safety equipment as required for the job you are performing with the
machine. Such equipment may include: hard hats, safety shoes, ear protectors, reflective
clothing, safety goggles, heavy gloves, etc., as well as safe work clothing.
●Do not wear rings, watches, jewelry, or other loose or hanging apparel that can catch on
moving parts while servicing the machine.
●The APU should only be operated or serviced by those who are qualified, responsible, and
delegated to do so.
14 | Page

Use the following safety procedures to ensure a safe workspace:
●Provide proper ventilation when operating an engine in a closed area to remove exhaust gases.
Breathing exhaust fumes may be fatal.
●Never use starting fluid around lighted smoking materials, sparks, or open flame.
●Do not place any of your body parts near a rotating fan, belt or power-driven part.
●When dealing with a servicing that pertains to the truck’s batteries, please remember that electric
storage batteries give off highly flammable hydrogen gases, and you should therefore avoid lighted
material, open flames, and/or sparks from being near the battery. Additionally, do not lay tools or
other conductive materials on the battery where they may cause short circuits and sparks.
●Use extreme caution when removing the radiator cap. Stop the engine and let it cool off before
removing the cap. When removing the cap, loosen it very slowly and avoid pressurized steam that
might be in the radiator. Coolant may be added ONLY when the engine is idling or stopped.
●Always use safety stands in conjunction with hydraulic jacks or hoists to avoid personal injury.
●Do not run the engine in an unsafe condition. If one is noticed, tag the unit so others will also know it.
●Ensure that there is a FIRE EXTINGUISHER nearby that is up to code.
●Know the location of an easy-to-access FIRST AID KIT for treatment to minor cuts and scratches.
15 | Page

NOTE:
●Hazards or unsafe practices could result in injury or death.
●Persistent inhalation of exhaust fumes may cause serious injury and/or death. Anyone suspected of
suffering from carbon monoxide inhalation should be removed from the hazardous area and given
immediate medical attention.
●Exercise extreme caution when working near fuel or flammable substances.
●Moving parts can cause severe injury and/or death. Before working on any unit, shut it off, and
make sure that the power supply is disconnected. If the power supply is not disconnected the unit
could automatically start up without warning. This could cause serious injury.
●It is not recommended for the APU to provide power to sensitive medical equipment.

10-STEP INSTALLATION
INSTALLATION OVERVIEW:
Before beginning installation of your HP2000, take time to inspect the unit and the desired area of installation. If you
believe you are missing a part, please consult the included checklist. Before you begin, perform an inspection of the
truck and installation area. Be sure that all batteries are fully charged and in good condition. We recommend that you
load test your battery bank prior to installation. Take your time to look over the area where you plan to install the
HP2000 and make necessary measurements to ensure proper installation. Make sure that you have at least 20.5” of
free frame rail space for power unit installation. Check to see that there is nothing behind the APU protruding more
than one inch. Also, make sure you have the necessary space available under the bunk for the evaporator unit and
cable pass through.
Before you get started, un-package your new system and all components. Inspect all components to make sure they
were not damaged during shipping. Examine your truck thoroughly, both inside and out, to locate the best place to
mount the APU. The diesel engine, A/C components and electrical controls are all contained in the frame-mounted
power unit enclosure, which measures 22.8” in height, by 20.5” in width, by 24.4” in depth. It is important to
remember that the APU location should not interfere with the driver’s access to other vital areas or crowd any wires,
air lines or fuel lines that may be nearby. While installation may vary slightly depending upon the make and model of
the truck it is installed on, proper installation will always be critical in guaranteeing proper operation of the APU system

STEP 1: MOUNTING THE APU
You are now ready to install the APU. Begin by mounting the APU to the frame rail. On most installations,
the HP2000 does not require any drilling into the frame rail.
●Using a lift cart or fork truck, position the APU against the frame rail in the desired location.
Make sure that the APU is perfectly level with the frame rail. Check the back of the APU to
ensure the bolt holes align with the top and bottom of the frame rail.
●Slide the patented low-pro mounting blocks onto the top frame rail, the two blocks will
mount to the bottom of the frame.
MAKE SURE THAT THE MOUNTING BLOCKS DO NOT INTERFERE WITH AIR LINES OR WIRING INSIDE THE
FRAME RAIL.
After confirming that the APU is level, tighten the mounting bolts to 80
ft-lbs in an X pattern. Do not over tighten the bolts past 80 lbs. This can
lead to damaging of the APU and its internal components.
19 | Page

STEP 2: EVAPORATOR SYSTEM AND DUCT HOSES
The evaporator system is designed to be mounted under the bunk
in the storage area. The evaporator system measures 18” in
length by 8” in height by 10” in depth. For the A/C hoses and
power supply cable, you will need a 3-inch hole in the floor
directly beneath the hose connection side of the evaporator.
Once the install location has been determined, check underneath
the cab to be sure that there are no supports, wires, hoses, cables
or beams where the three inch hole must be cut. This hole will
serve as a pass through for cables and hoses for the evaporator
system.
