Mounting

CAUTION

The Kooltronic HL Series Air Conditioners K3A4C12HL56LV have been engineered to be installed easily.  Prior to
mounting, refer to page 13 for the mounting plan showing dimensions and locations of mounting holes and
cutouts. Prior to cutting or drilling, make sure that cutouts and mounting holes do not interfere with components
inside the cabinet. To avoid damaging your air conditioner, please read the following information before installation:

1. It is recommended that a lift truck be used for installation.

2. These externally mounted air conditioners utilize a gasket to ensure a proper seal. This seal is necessary to 

maintain the integrity of the closed-loop system and the enclosure NEMA 4 or NEMA 4X Rating. 

3. Secure the air conditioner to the enclosure using (24) 

1/4

-20 x 1-

1/4

inch stainless steel bolts (supplied).

4. Using a clamp, attach plastic drain hose to the drain tubing near the bottom of the air conditioner.

5. The customer must connect the Purge/Pressurized System control line to the Swagelok fitting (B400-1-OR, 

1/4 inch NPT). The customer has a choice of two connection fittings on the unit. One is for internal connection,
and the other is for external connection (see illustration below). The unused fitting must be sealed with the 
provided cap. 

6. The customer could use a Tee fitting, or any type fitting to connect the Purge/Pressurized System control 

line to the air conditioner.

The air conditioner must be mounted in accordance with the mounting instructions in order

to maintain the integrity of the panel enclosure.
