Since this is a custom installation, many of our procedures can be viewed as suggestions. Your personal preferences will 

play a major role in the actual installation.

PLANNING INSTALL

•  drier needs to be mounted in a location where hoses can reach. Refrigerant hoses from condenser & evaporator 

must connect to it. 

•  drier mounts vertical with connections on top. Threaded connection labeled “IN” will connect to the lower 

connection of the condenser. 

•  do not leave drier open longer than a couple minutes. Doing so will require the drier to be replaced.

•  the drier has a location for the pressure switch/trinary switch to thread into.

Receiver/driers are located in the high-pressure section of the system, usually in the plumbing between the 

condenser outlet & the expansion valve inlet, although some may be connected directly to the condenser. 
They serve 3 very important functions:

   1. They act as a temporary storage container for oil & refrigerant when neither are needed for system operation 

(such as during periods of low cooling demand). This is the “receiver” function of the receiver/drier.

   2. They trap very small debris that may be inside the a/c system.

   3. They contain desiccant. The desiccant is used to absorb moisture that may have gotten inside the a/c system 

during manufacture, assembly or service. Moisture can get into the a/c components from humidity in the air. This is 

the “drier” function of the receiver/drier. 
Damage can occur if there is excessive moisture inside an a/c system. It can cause corrosion, as well as possibly 

degrade the performance of the compressor’s lubricating oil.
The receiver/drier should be replaced any time the system is opened for service, and most compressor warranties 

require it. The desiccant is only capable of absorbing a certain amount of moisture, and when the inside of the 

system and/or the receiver/drier are exposed to the atmosphere, the desiccant can become very quickly saturated 

from humidity in the air. If this occurs, the desiccant is no longer effective, and will not provide future protection. 

Additionally, the filter inside the receiver/drier could be restricted by debris that may have been inside the system. 

This could diminish refrigerant and oil flow.

LOCATION OF DRIER

•  make certain hoses have enough slack when connecting to compressor so that fittings do not prematurely 

fatigue w/engine vibrations

•  make certain hoses are secured with supplied clamps so hoses don’t rub against objects

•  hose fittings must be crimped by a reputable service center or can be sent back to us.

•  hydraulic crimping cannot be used, automotive a/c crimping dies are only suitable for refrigerant barrier 

hoses.

LOCATION OF HOSES

Condenser is purchased seperate. Make sure you have the largest possible size condenser for your vehicle. Surface area is important for maximum 

cooling. Rule of thumb is condenser size matches the “finned” area of the radiator.

•  condenser needs to be mounted in a location where hoses can reach

•  should be within 1” from radiator without touching

•  condenser has 2 fitting connection: larger #8 connection on top, smaller #6 on bottom.
Fab condenser mounting brackets to minimize condenser movement. Can be mounted w/fitting connections on passenger/driver side. You can not lay 

down condenser flat/parallel to the ground. The oil within the system is heavier & thicker than refrigerant gas. The gas separates leaving the oil trapped 

in the condenser, ultimately starving the compressor of lubrication.
            Failure to mount condenser with large fitting on top will result in system functioning incorrectly.

LOCATION OF THE CONDENSER

Use installation instructions provided by your engine bracket manufacturer.
            Most brackets mount compressors either passenger or driver side.

            Compressor fittings cannot be mounted with fittings downward
