Kooltronic KNA4C7P59L 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 65ºF to allow the system to warm up.
2. Refer to the nameplate 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.
3. Note the factory thermostat setting which is 75ºF to 80ºF. Adjust the thermostat to its maximum setting.
4. If your unit is equipped with an on-off switch, move it to the on position. Turn the electrical power on. Verify that the evaporator blower or fan is running.
5. Adjust the thermostat to its minimum setting. The compressor should start. On units equipped with a short cycle protector, the compressor will have a delayed start of six
(6) minutes from the time power is applied to the unit.
6. Verify that the condenser blower or fan is running. On units equipped with a low ambient kit, the start of the condenser fan or blower will be delayed until the system
pressures rise.
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.
8. On units equipped with heaters, adjust both the cooling and heating thermostats to their maximum settings. Verify that the compressor and condenser fan or blower has
stopped. Verify elevated discharge air temperature from the evaporator air discharge.
9. If your unit is equipped with an on-off switch, leave it in the on position. Return the cooling thermostat to its original setting. If the unit is equipped with a heater, return
the heating thermostat to its original position. Turn off the electrical power and disconnect the air conditioner from the power source.
10. 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

Kooltronic Air Conditioners have been engineered to be installed easily. To avoid damaging your air conditioner, please read the following information before installation. Refer to
mounting drawings on next page for dimensions and locations of mounting holes and cutouts:
1. Remove and discard (2) nuts and washers holding the Mounting Template and Assembly Bracket (M/TAB) to the Air Conditioner. Remove M/TAB.
2. Place the M/TAB flush against the outside of the cabinet to locate cutouts and M/TAB mounting holes. The minimum distance between lower end of the M/TAB to the
ground is 14" for all P59 units.
3. The cutout for warm air return does not have to match the full 9
return air cutout from the cabinet as large as possible. Make the cold air supply cutout the same size as on the M/TAB.
4. Mount the M/TAB to the outside of the cabinet using all the 1/4-20 x 1/2" bolts, washers and nuts supplied by Kooltronic.
5. Route the power cord through the return air cutout of the cabinet. Mount the air conditioner on the M/TAB by sliding the (4) mounting studs, installed on the air conditioner side
panels, into the (4) inclined slots of the M/TAB.
6. Carefully mark all mounting holes from the flanges of the air conditioner to the cabinet wall. All holes in the air conditioner flange must be used to maintain the NEMA 4 rating.
7. Remove the air conditioner from the M/TAB and drill .218" dia. mounting holes in the cabinet. Do not attempt to drill mounting holes in the enclosure without first removing
the air conditioner. Drilling through the sealing gasket may damage it and remove the NEMA 4 rating. Repeat actions, described in item "5" above.
8. Insert the stainless steel screws with seal washers supplied through holes in the mounting flanges and the cabinet wall. Install washers and nuts on each screw from
inside of the cabinet and hand tighten. Tighten all nuts to a torque of 20 in.-lbs. going in a clockwise rotation starting from the top left corner. Retighten to a final torque
of 34-40 in.-lbs. in the same rotation as previously used. The torque should be rechecked after the gasket has been allowed to set for 1 hr. and again after the air
conditioner has been run for 24 hrs. Check the flange gasket compression, after tightening all nuts - the gasket should be compressed by approximately 1/2 the gasket
thickness (1/8").
9. After making sure that the source voltage and frequency are the same as shown on the unit nameplate, connect the air conditioner's power cord to the power supply.
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
technical data can be found in the performance specifications in the Operator's Manual available online.
