SHIPPING DAMAGE

Upon receipt of equipment, the unit should be checked 
for external signs of shipping damage.  The skid must 
remain attached until the unit is ready for installation.  
If damage is found, the receiving party must contact 
the last carrier immediately, preferably in writing, 
requesting inspection by the carrier’s agent.

UNIT REMOVAL FROM SKID

HANDLING UNIT AFTER REMOVAL 

FROM SKID

If a wide and tall enough opening exists, the I-TEC can 
be moved as a complete assembled unit.  If not, it is 
designed  to break down into two sections to allow it to 
pass through a 36" wide door.
1.  Depress and release both top and bottom door latches 

and open doors.

2.  Remove the doors by lifting straight up and off from 

the hinge pins.

3.  Remove cabinet sides by first removing the four (4) 

sheet metal screws from the front (leading edge) of the 
side panel.  The panel will not fall off.  Swing the panel 
away from the chassis 20-30

˚

 and then pull forward 

from the two (2) tabs supporting the rear edge.

4.  On each side of the unit is a tie plate that secures 

the top and bottom sections with four (4) cap bolts.  
Using a ½" wrench or socket, remove these screws 
from both plates and set aside.

5.  If the unit is equipped with a CRV or ERV, unplug the 

wire harness on the left-hand side of the control box.

6. 

A forklift or a lift rated for the load is required to lift 

the top section off from the bottom base.  Do not 

attempt to do this manually.  Failure to do so could 

result in the unit tipping over and causing bodily 

injury and/or damage to the unit.

7.  The top section can be forked from either the 

right-hand or left-hand side.  See Figure 1 for fork 
openings.

8.  Carefully lift the top section straight up avoiding tipping.
9.  Move the top section through the doorway and place 

on flat surface free of debris.

10. The bottom base can now be moved through the 

doorway the same way.

11. Reassemble the unit by reversing this procedure.

FIGURE 2A – Unit on Lift

FIGURE 2B – Unit Side

A forklift or a lift rated for the load (Figure 2A) is 
required to lift the unit off from the skid.  This unit is 
top heavy and should never be tipped while moving it.

The I-TEC is designed to be lifted off the skid from the 
front or rear of the unit without having to remove any 
doors or side panels.  See Figure 1 for fork openings.  
The shipping brackets on front and rear of the unit 
must be removed and discarded.  The unit can now 
be lifted straight up and the skid can be slid out from 
underneath.

        WARNING

This unit is heavy and requires more than one person 

to handle during installation and removal from the skid.  

Extreme caution must be taken to prevent injury to 

personnel and damage to the unit.  Use appropriate safety 

equipment, including gloves when handling.  Failure to do 

so may result in serious injury.

Tip unit from left side only.

Failure to do so may result in injury due to  

unit top-heaviness or compressor damage!
