Note: If the system to be wall mounted is a freezer model 100 or 150 or cooler model 075, please see the next

section with special instructions on mounting these units.

Carefully raise the entire refrigeration system and insert the projecting sleeve of the evaporator section into the

opening of the walk-in wall. While supporting the system, lock it into position by turning the locks exactly as you

did when locking the walk-in sections together. Make sure that the locks are positively engaged and insert the plug

buttons into the lock access holes when finished. Refer to Figure 1.

Note: Some motor compressors are openly spring mounted to absorb vibration. Be sure that these bolts are

loosened to permit the compressor to float freely on the springs. A reminder label is applied to systems where this

procedure applies.

Some systems require a permanent connection to an electrical service and a connection at the junction box located

within the condensing unit housing. Refer to the serial tag for all pertinent electrical data. These systems must be
connected to a power supply disconnect switch and wired according to local and national electric codes.

No plumbing drain is required, under normal conditions, for indoor installations. A built-in hot gas vaporizer

dissipates the condensate moisture automatically. In outdoor installations, the condensate should be plumbed to

the nearest drain. Check local building codes. Outside drain lines must also be wrapped with a suitable heater wire

if they are ever subjected to below freezing temperatures. Outdoor installations also require the attachment of the

rain hood that will divert rainfall from the upper surface of the evaporator housing. See Figure 1 for an illustration.

Be sure to allow for sufficient airflow around the condenser. A minimum clearance of six inches is required for

installation and a minimum of two feet is required for service consideration. Ambient temperature around the

system should be less than 90

°F and 50% RH. If multiple units are located in the same area, be sure they do not

exhaust hot air flows into one another. In addition to allowing for proper airflow, consideration should be given to

the final mounting location of the refrigeration system relative to the customer location to avoid any possible risk

of noise impacting the customer experience.

Please see the section “Instructions for Pre-Charged Lines” if the installation of this system involves the use of

pre-charged lines to connect the evaporator and condenser sections.
