Kooltronic K3NA4C11SP43L 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 be operated in its proper mounting position. If attempts are made to operate the unit not in its designed mounting position, permanent compressor
damage will occur. This action will void the warranty. The unit must sit in its proper mounting position for a minimum of five (5) minutes to allow the compressor oil
to settle, at a minimum room temperature of 65ºF.
2. Refer to the nameplate for proper electrical voltage and current requirements. Connect the power inlet conductors to a properly grounded and fused electrical supply,
leaving electrical power to the unit turned off.
3. Turn the electrical power on.
4. Verify that the evaporator blower or fan is running.
5. Observe the temperature on the digital display. The thermostat must be set a minimum of 10ºF below this temperature for the compressor to operate (the factory setting
is 75ºF). To adjust the thermostat, push the set button for two (2) seconds, then use the arrows to set the temperature.
6. The compressor in this air conditioner is protected by a phase sequence/phase loss detector. If the compressor does not start when power is applied to the air
conditioner, check to ensure all three phases are energized. If voltage is present at all three phases, disconnect the power input and reverse two power input leads.
Reapply power and check for proper unit operation.
7. 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 70ºF when the room temperature is between
70ºF and 80ºF. It is normal for the condenser blower to cycle on/off during this period.
8. Reset the thermostat to the factory setting of 75ºF. WARNING: Operating the unit below 75ºF may result in freezing of the evaporator coil.
9. Turn off the electrical power and disconnect the air conditioner from the power source.
10. If a 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

Kooltronic Air Conditioners have been engineered to be installed easily. To avoid damaging your air conditioner, please
read the following information before installation:
1. These externally mounted air conditioners have pre-installed gaskets 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.
2. Attach mounting hooks to unit using the supplied (4) #10-32 x
3. Position the air conditioner against the enclosure with the mounting hooks in the upper cutout to aid in aligning
the mounting holes.
4. Secure the air conditioner to the enclosure using the supplied (13)
5. Attach plastic drain hose to the drain tubing on the bottom of the air conditioner with supplied clamp.
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.
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 125 lbs. Additional technical
data can be found in the performance specifications in the Operator's
Manual available online.
