Kooltronic KA4C9DP47L Installation Instructions

I. Introduction
These instructions provide you with the general information necessary for proper installation of the air conditioners.
BEFORE INSTALLING THE AIR CONDITIONER, IT IS IMPORTANT THAT THESE INSTRUCTIONS BE READ AND UNDERSTOOD THOROUGHLY
II. Incoming Inspection
Kooltronic Air Conditioners are designed, built and packaged to withstand the shock and vibration normally associated with shipment by common carriers. Occasionally
improper handling during shipping causes damage. Such handling could include unbanding of palletized shipments, failing to respect "This Side Up" arrows, rough
handling, falling off conveyors, excessive vibration, crushing, etc. Therefore, a thorough inspection should be done upon receipt of all shipments. Any carton tears, dents,
scratches, loose articles or evidence of oil are signs of damage and should be noted on the Freight Bill. Cartons should be opened promptly and the units inspected for
CONCEALED DAMAGE. Kooltronic Air Conditioners must be delivered in the proper mounting position to assure that damage to the compressor has not occurred during
shipping. Any Kooltronic Air Conditioner that is delivered removed from the banded pallet, lying down or double stacked should be refused.
An immediate claim MUST be filed with the freight carrier and an inspection requested. Retain all packing materials. Kooltronic cannot assume responsibility for Consignee's
failure to file a timely freight claim.
III. Pre-Installation Testing
1. The unit must sit in an upright position at a minimum room temperature of 65°F to allow the system to warm-up. This is particularly important during winter months.
2. Refer to the identification label for proper electrical voltage and current requirements. Connect the power cord to a properly grounded and fused electrical supply,
leaving electrical power to the unit turned off. Note the factory thermostat setting which is 75°F.
3. Turn the electrical power on. Verify that the evaporator blower or fan is running. Condenser impeller should start immediately
and after one (1) second, stop. After three (3) to five (5) minutes the condenser impeller should start. Verify that the
condenser blower or fan is running.
4. Operate the air conditioner for approximately ten (10) minutes. During this period no unusual noise or vibration should be
evident. Both the evaporator and condenser fans or blowers should be delivering air through their respective discharge ports.
The cool air discharged should be less than 70°F when the room temperature is between 70°F and 80°F.
5. If the ambient temperature is below 75°F, after fifteen (15) minutes the thermostat will shut off the compressor and condenser
impeller.
6. Turn off the electrical power and disconnect the air conditioner from the power source.
7. If any cover plug was removed to adjust the unit, be sure to replace it in order to maintain the integrity of the closed-loop
airflow system.
IV. Mounting
External Mounting
1 /
1. Place the supplied -inch gaskets on the two evaporator side cutouts as shown in the gasket drawing on next page. The
2
gaskets must start and end at the middle bottom of the cutouts. The gaskets must remain as one continuous piece around
the cutouts. Bend gaskets around the corners. Do not stretch the gaskets.
2. It is recommended that a lift truck be used for installation.
3. Attach the Mounting Plate to the enclosure using (3)
mounting nuts. Note that the mounting plate is not symmetrical. Be sure to install with the longer section at the top and
the shorter section at the bottom. Sealing washers must be placed against customer enclosure (see External Mounting
Drawing and Mounting Plate Detail).
4. Place the air conditioner on the lift truck. Insert a 1-inch (approximate) wooden block between the lift truck bottom and the
air conditioner bottom so that the angle between the unit mounting panel and the air conditioner is about 10 degrees.
5. Adjust the lift truck height so that the air conditioner hook is located approximately
6. Route the power cord through the discharge (upper) air cutout.
7. Move the air conditioner toward the enclosure panel so that the gap between the hook and the enclosure is about
8. Slowly move the lift truck down until the hook engages with the mounting plate. Continue to lower the lift truck. The air
conditioner will hang from the mounting plate flush against the mounting panel.
9. Insert screws through the holes in the mounting plate bottom flange and the enclosure panel. Install sealing washers and
nuts on each screw from inside the enclosure and tighten (see External Mounting Drawing).
Internal Mounting
1 /
1. Place the supplied -inch gaskets on the two condenser side cutouts as shown in the gasket drawing on next page.
2
The gaskets must start and end at the middle top of the cutouts. The gaskets must remain as one continuous piece
around the cutouts. Bend gaskets around the corners. Do not stretch the gaskets.
2. Remove the three #10 screws together with rubber washers from the Rear Panel top.
3. Attach the supplied mounting angle to the Rear Panel top with the three #10 screws and rubber washers (see Internal
Mounting Drawing).

4. It is recommended that -inch x 1
4
use the hardware supplied for air conditioner mounting.
Kooltronic Air Conditioners must be standing in their proper mounting position for a minimum of five (5) minutes prior to testing. Failure to
follow this procedure will cause permanent damage to the compressor. To avoid compressor damage do not tip the unit more than 45 ° from
its proper mounting position
Kooltronic Air Conditioners must be operated in their proper mounting position. If attempts are made to operate a unit that is not in its designed
mounting position, permanent compressor damage will occur. This action will void the warranty.
If the air conditioner is mounted to the cabinet door you must be sure that the door hinges will support the additional weight of the air conditioner.
Also be certain that when the door is opened fully, the cabinet does not become unbalanced. The weight of the unit is 135 lbs. Additional technical
data can be found in the performance specifications in the Operator's Manual available online.
