1. Warnings ! WARNING • Whenever water and electricity are combined in the same enclosed environment the possibility of electric shock exists. This unit must only be plugged into a three conductor, grounded GFI (Ground Fault Interrupt), power source. Do not open the unit with power applied to the unit. Do not place the unit on a slope or where it can accidentally fall or roll into water. • Wiring And Connections Must Comply With All National And Local Electrical Codes.
3. PolarCool Performance The following table shows estimates of the performance of three sizes of the PolarCool Evaporative Cooling System. These values will vary depending on the particular installation and operating conditions. Both Variable Speed(VS) and Single Speed(SS) models are listed. Drive Water Consumption Rates (See Note 1) Power Consumption Typical Air Movement Rates (cubic feet per minute- See Note 2) 18” VS Direct 5 gallons per hr.
4. Controls New for 2008, the 18” and 36” Variable Speed PolarCool units feature a completely redesigned control panel interface. The new control panel provides a user friendly interface with status indicator lights. The 24” and 48” PolarCool models have two valves and two switches. Their functions are as follows: 4.1 • • 4.2 • • • • • • • Valves Discharge Valve (24” and 48” models only) – Used when pumping out the reservoir for cleaning and extended shutdown (Down time greater than 24 hours).
4.3 • Switches Section 4.3 pertains only to the 24” Variable Speed Model and the 36” & 48” Single Speed Models. Fan Control Switch – Used to start and stop the fan. This switch is the one on the left when looking at the bank of switches. Note: Some models come with two speed and others with variable speed fans. Refer to the figure below for available models and fan speeds.
5. Installation and Preparation 5.1 Wheel Installation Warning! PolarCool Appliance Is Heavy! When Installing Wheels, Provide Adequate Support To Maintain Balance Of Appliance! IMPORTANT! Ensure the washers are placed between the wheel bracket and the wheel channel. Carriage Bolts Washers Caster Support Channel Caster Bracket Swivel Wheels w/Lock Rigid Wheels Nylon-Insert Nuts w/o Lock 1. Place wheel bracket against the caster support channel with the 5/16 washers in between as shown above. 2.
5.2 Unpacking PolarCool IMPORTANT! Remove Tape From Float Before Operating! Follow Instructions Below. Diagram 1 INSTRUCTIONS: 1. 2. 3. Carefully unpack PolarCool from shipping carton. Lift Cover to gain access to pads as shown in Diagram 1 at right. Tilt pads as shown. Remove pads to access float. Float is securely taped to bottom of PolarCool for shipment. USE HAND AND APPLY PRESSURE TO HOLD FLOAT IN PLACE.
5.3 230 VAC /50 hz Wiring Diagram The 230 VAC /50 hz PolarCool models are supplied with a stubbed power cord which must be wired to the specific plug necessary to match local, state, and national electrical receptacles. ! WARNING • Whenever water and electricity are combined in the same enclosed environment the possibility of electric shock exists. This unit must only be plugged into a three conductor, grounded GFI (Ground Fault Interrupt), power source.
5.5 Shut Down When you are finished with the PolarCool, follow these steps for shutting down the unit. 1. Turn off pump. 2. Wait ten to fifteen minutes (This will dry the pad and minimize algae growth). 3. Turn off fan. 4. Disconnect water and power to the unit. 5. If water is not disconnected, turn off water hose to PolarCool whenever PolarCool is not in use. 6. Operation 6.1 Ventilation is Very Important Fresh air is very important for proper operation of evaporative cooling.
7.2 Frequency Of Pad Replacement PolarCool pads, produced from a cellulose base and impregnated with a plastic resin anti-rot agent, can give years of trouble free operation with proper maintenance (3 to 5 years is typical). Rotate Spray Bar Lift Cover Remove Pads Spray Deflector NOTE: When lowering the cover, do not force the cover closed. Ensure the Spray Bar is correctly centered beneath the Spray Deflector. 18" PolarCool Pad Removal 7.
7.3.4 Why Drain Water From The System? If you have ever left a pot of coffee warming on the coffee maker you know the two principles at work in evaporative cooling systems. First, as the coffee sits on the warming plate, the level of water in the pot goes down. Second, the remaining coffee gets stronger as the water evaporates. In your cooling system, these effects still apply. As water evaporates, no impurities are carried along. This leaves all sorts of minerals, chemicals, and other impurities behind.
7.5 Cleaning the Pump Filter The water pump includes a removable plastic filter on the bottom of the pump which should be cleaned weekly when the reservoir is flushed. 1. Turn off the pump, fan, and water source, and NOTE: Do not allow the pump to run without water unplug the unit. in the reservoir. Without water, the pump may be 2. Remove the pump from the reservoir, remove damaged. and clean the screen on the bottom of the motor, 3. Restore the water source and fill the reservoir.
7.9 Belt Inspection or Removal (48” Model Only) 1. 2. 3. Disconnect all electrical power to PolarCool! Diagram A To open belt, twist and Remove pads. push tabs through holes. TEST FOR LOOSE BELT: Press on belt with finger about halfway between pulleys. Belt should deflect about 3/4" if correctly fitted. 4. To remove belt, slowly rotate belt while carefully rolling belt off of prop pulley. 5. After removing belt, turn belt inside out. Links should NOTE: Section of belt shown inside out.
8. 9. Repeat steps 1 thru 7 above as required for proper adjustment of water level. NOTE: Water level in reservoir is normally 2-1/4" ± 1". Do not allow the reservoir water to contact the pads when the reservoir water level is at the highest point. Flow Control Valve After adjusting water level, return PolarCool to service. 7.11 Flow Control Adjustment Flow control adjustments are available on the 18″ model (2007 models and earlier) on the bottom of the pump as shown in Section 7.
8. PolarCool Preventive Maintenance Requirements • • • • • • • • Flush the system at least once per week and wipe the reservoir clean to prevent damage to the unit. Refer to Section 7.4. Allow the pads to dry out each day, by running the fan without the pump running until the pads are completely dry (about 15 minutes). Drain the system during extended shutdowns. Disinfect the whole system once per quarter. Routinely inspect fan belt (48” model only) for looseness and inspect spray bar for debris in holes.
