Installation - (2) ES300 Evaporators

Support Plates

Thermo King recommends securely installing steel support plates with 
mounting studs (installer supplied) directly to the truck’s interior roof 
structure to safely support the weight of the ES300 evaporators prior to 
insulating and finishing the cargo area. The support plates should be 
correctly located to position the evaporator the required distance from the 
compartment front bulkhead wall to allow refrigerant and drain hose 
connections. See “Tips for a Successful Installation” on page 8, 
“Dimensions and Weight - ES300 Host Evaporator” on page 13 and 
“Dimensions and Weight - ES300 Remote Evaporator” on page 14. 

Preferred Installation Method

(with pre-installed support plates)

IMPORTANT: Be sure to install the correct evaporator in each 
compartment. The HOST evaporator has drain pan heater wires while 
the REMOTE evaporator does not.

1. Remove the plastic cover from each evaporator.

2. Position the HOST evaporator onto (installer supplied) ceiling 

mounting studs in the Frozen Compartment

Install washers and locking nuts and tighten hardware securely.

3. Position accumulator assembly at the rear of REMOTE evaporator: 

Connect the supplied 7/8” tube assembly with o-rings to the mating 
fitting inside the evaporator.

Secure the accumulator to the rear of the evaporator with supplied 
hardware and tighten securely.

4. Position the REMOTE evaporator onto (installer supplied) ceiling 

mounting studs in the Fresh Compartment.

Install washers and locking nuts and tighten hardware securely.

NOTE: The covers for both evaporators will be installed later.

Alternative Installation Method

(without pre-installed support plates)

1. Locate and mark the center line (C/L) of the interior compartment 

ceiling.

2. HOST evaporator - Allow a minimum distance of 152 mm (6.00 in.) 

from the cargo area wall to the rear of the evaporator for refrigerant 
hose and drain hose connections.

REMOTE evaporator (with accumulator assembly) Allow a 
minimum distance of 152 mm (6.00 in.) from the cargo area wall to the 
rear of the accumulator assembly for refrigerant hose and drain hose 
connections.

3. Position each evaporator up to the ceiling and mark the location of the 

four mounting holes. NOTE: Be sure the evaporator’s air outlet is 
facing the correct direction for proper airflow.

4. Drill four 5 mm (0.472 in.) mounting holes into the ceiling and loosely 

install the supplied 1/4” lag bolts and washers. 

5. Remove the plastic cover from each evaporator.

6. Position accumulator assembly at the rear of REMOTE evaporator: 

Connect the supplied 7/8” tube assembly with o-rings to the mating 
fitting inside the evaporator.

Secure the accumulator to the rear of the evaporator with supplied 
hardware and tighten securely.

7. Apply neutral/alcohol cure silicone sealant (installer supplied) per the 

sealant manufacturer’s instructions to the top surface area of the 
evaporator.

8. Install the HOST evaporator onto the ceiling of Frozen Compartment 

with the 1/4” lag bolts and washers and hand tighten bolts securely.

9. Install the REMOTE evaporator onto the ceiling of Fresh 

Compartment with the 1/4” lag bolts and washers and hand tighten 
bolts securely.

NOTE: The evaporator covers will be installed later
