I. INTRODUCTION The PORT-A-COOL® unit is a fully self-contained, portable, high efficiency evaporative cooler that is proudly made in America at our factory located in Center, Texas. A. What is Evaporative Cooling? When trying to understand evaporative cooling, it may be best to think of air as being like a sponge, in that regard, air has an ability to absorb moisture that it comes in contact with.
The following table demonstrates the BTU’s removed from the air based on a given amount of water evaporated in an hour by the PORT-A-COOL® unit. U. S. Gallons / Hour Total BTU’s Removed 10 (37.8 liters or 8.3 Imperial Gallons) 87,000 12 (45.4 liters or 10.0 Imperial Gallons) 104,400 14 (53.0 liters or 11.7 Imperial Gallons) 121,800 For actual temperature drops refer to Appendix A. In simple terms, evaporative cooling is nature’s way of cooling.
C. Evaporative Cooling and the PORT-A-COOL® unit. The PORT-A-COOL® unit is the state-of-the-art, high efficiency, portable evaporative cooling system that utilizes high efficiency Küül® brand, rigid cooling media, manufactured with the patent pending “thru-cure” ™ process.The PORT-A-COOL® unit’s unique patented housing enclosure, along with the Küül® brand high efficiency cooling media, allows the unit to cool effectively in very high relative humidity conditions.
I. SETUP A. Unpacking the PORT-A-COOL@ unit. The PORT A-COOL HAZARDOUS LOCATION MODELS (PAC2K36EP and PAC2K48EP) are shipped strapped to a plastic pallet with a large cover box strapped over the PORT-A-COOL® unit. It is a simple matter to cut the strap and remove the box by lifting it over the PORT-A-COOL® unit. This will expose the plastic dust cover. Remove the dust cover. At this time two (2) people can remove the PORT-A-COOL® unit from the pallet.
Water supply inlet pressure should be limited to 50 psi maximum. The cooling pads may now be replaced by reversing the removal operation above in Section I. Paragraph B. Electrical Connection PORT-A-COOL® unit must be upright and sitting on caddy with cooling pads installed! These models utilize a single power cord and control switches. The power cord on this unit is 50’ of 14-gauge 3-wire grounded cord with out plug, so the unit can be wired to meet local code requirements.
II. OPERATING PROCEDURES A. Placement of the PORT-A-COOL@ unit. PORT-A-COOL@ units should be used in well-ventilated areas only. There are three primary considerations when deciding where to place the PORT-A-COOL® unit. 1) Fresh Air Supply -The rear of the unit (pad area) must be placed so to insure that a smooth, uninterrupted supply of fresh air is available. 2) Air Pattern -The cool air discharged from the PORT-A-COOL® unit should have a clear area to circulate in, as free of obstruction as possible.
CAUTION - DO NOT LEAVE PRIME VALVE ON OR THE UNIT MAY FLOOD! When initially turning on the pump, the level in the sump will drop suddenly and restart the flow of supply water. This is a normal condition as the cooling pads require a large amount of water for proper wetting. When the PORT-A-COOL® unit is new, the new pads will require an initial ‘breaking-in’ period. This period is required to start the pads absorbing the water into the paper. It may take up to a week before maximum efficiency is reached.
Ill. MAINTENANCE & STORAGE Very little maintenance is actually required on the PORT-A-COOL® unit. The primary topic which accounts for most of the maintenance on the PORT-A-COOL® unit is cleanliness. Keeping the PORT-A-COOL® unit clean will do more than any other single item to keep your new PORT-A-COOL® unit in peak operating condition. The rugged, corrosion-resistant construction of the PORT-A-COOL® unit and industrial grade components make for the low maintenance characteristics of the PORT-A-COOL® unit.
V. TROUBLESHOOTING / REPAIR NOTICE: POWER CORD MAY BE REPLACED ONLY BY THE MANUFACTURER OR QUALIFIED AGENT!! A. Troubleshooting The most common problems encountered with a PORT-A-COOL® unit are operational problems. The PORT-A-COOL® unit consists of three systems. It is important to determine which system of the PORT-A-COOL® unit the problem is associated with. Certain problems may be associated with more than one system.
FAN SYSTEM CAUTION Please use caution when troubleshooting or repairing all electrical components. Be certain that all power is disconnected from the PORT-A-COOL® unit before the cooling pads are removed to gain access to the fan. BELT DRIVE MODELS PROBLEM CHECK SOLUTION Fan motor won’t run and makes no sound. Power cord, switches, circuit creaker, etc. Reconnect power, reset breaker. Fan motor won’t run and makes a humming sound. Blade in contact with shroud Check mounting bolts.
WATER SYSTEM The water system consists of three primary elements: 1) Water Delivery System, 2) Spray Bar Assembly; 3) Pump. Troubleshooting of this system is fairly simple. The Water Delivery System consists of two assemblies: A) The Water Inlet assembly and B) The Plumbing assembly. The Water Inlet assembly is made up of four components: 1) The water supply connection hose, 2) The bulkhead fitting, 3) The float valve connection hose and 4) The float valve.
PLUMBING ASSEMBLY PROBLEM CHECK SOLUTION Water spitting from the from the unit. Cracked riser assembly. Spray Bar Adjustment valve. Replace riser assembly. Water leaking from Drain Valve. Washer worn. Stem worn. Replace washer. Replace Drain Valve. Water leaking from Spray Bar Valve. Washer worn. Stem worn. Replace washer. Replace Spray Bar Valve. SPRAY BAR ASSEMBLY (ALL MODELS) PROBLEM CHECK SOLUTION Too many dry streaks in the pads. by foreign material.
B. Repair Procedures Only qualified and trained distributors or factory personnel should perform repairs!! VI. REPLACEMENT PARTS A. Returned Merchandise Authorization (RMA) Procedures All Port-A-Cool® units, parts, or materials being returned to Port-A-Cool, LLC for warranty replacement or repair require an RMA (Return Merchandise Authorization) number. There are two methods for replacing waranty parts: 1.
