Belt installation and adjustment
To install belt:
1.
Place the belt over the motor pulley.
2.
Place the free end of the belt into the blower pulley.
3.
Rotate the blower pulley until the belt lies fully in the groove.
Ensure not to pinch fingers between the pulley and the belt
Test the belt tension by pressing on the belt mid-way between the pulleys. With only 3 to 4
pounds of pressure, you should be able to deflect the belt between ¾ and 1 inch.
If the belt needs to be adjusted:
1.
Push up on the motor to get an idea of how much the belt tension bracket should be adjusted.
2.
To tighten the belt: Remove the belt and adjust the bracket accordingly.
3.
To loosen the belt: Remove the belt and adjust the bracket accordingly.
After the installation is complete, fill the cooler pan with water. Check for leaks at the drain
coupling and the float valve coupling. Adjust the water level by resetting the adjustment screw at the base of the float rod. Check that
the base of the cooler is level. To prevent rust a coating of good quality axle grease may be applied to the shaft and bearings.
Post installation inspection
1.
Cooler is securely fastened to the roof jack
2.
Base is level (check after full of water)
3.
Ensure duct is sealed
4.
Check all connections for water leaks
5.
Check for correct water level
6.
Ensure all electrical connections and wiring conform to
applicable codes and motor and pump are plugged into
junction receptacle
7.
Ensure motor is securely fastened to mount, the pulleys are
aligned and the belt is tensioned properly
8.
Ensure the hose is installed securely to the pump and to the
water distributor
9.
Turn on main power supply
10.
Check pump operation by turning the control switch to
PUMP ONLY. Check that all pads wet evenly
11.
Check the high and low fan speeds with and without the
pump running.
Operation
Before you put your new cooler into operation, pour a cap full of laundry fabric softener (any brand) into the water and run the cooler
on PUMP ONLY for 10 to 15 minutes or until the pads are thoroughly saturated.
You control the airflow of the cooler into what rooms you wish cooled. To allow cooling in a particular room, open a window, exterior
door or vent in that room. The cool air from your cooler will tend to go to the rooms that have some sort of opening to allow for
exhaust to the outside of the house.
A rule of thumb used for deciding how far to open each window or how many windows to open is to allow 2 square feet of exhaust for
each 1000 CFM of airflow. For example, the TC451 delivers 4100 CFM; therefore, you will need approximately 8 square feet of
exhaust area.
For replacement purposes…
Pads:
Use only HiKool Plastic UL Class II evaporative pads.
Pumps:
Use only three-pronged molded plug UL listed pumps 5000CFM for TS451 & TC451 – 7000CFM for TS571 & TC571.
Motors:
use only evaporative cooler motors. ½ HP TS451 & TC451 – ¾ HP TS571 & TC571.
Maintenance
Warning:
Always shut off the electrical power to the unit at the fuse or breaker box and unplug the motor, pump from the junction
receptacle and shutoff the water supply before attempting any type of maintenance or service work.
Oiling
1.
Oil the bearings and motor often (twice a season minimum).
2.
The bearings are provided with oil cups. Lift the hinged lid on the cup and add a couple of drops of oil. Do not over oil, excessive oil
can enter the air stream.
3.
If the motor is provided with oil cups, then oil the motor when you oil the bearings. Do not over oil, if oil gets into the motor, damage
may occur.
Cleaning the water distributor
1.
Disconnect the vinyl tubing connecting the pump and water distributor.
2.
Turn the water distributor clamps in the top of the cooler, lower the distributor and pull (twist) apart at the tan connectors.
3.
Tap ends lightly on a hard surface to dislodge mineral deposits and flush with a garden hose.
4.
A nail may be used to clean deposits from the holes in the distributor. DO NOT distort or enlarge holes while cleaning.
Do not attempt to clean the water distributor while on the roof.
Mineral build up
Mineral deposits may collect on the louvers and around the base of the cooler. These deposits may be removed easily with a little
water and a nylon scrub brush (never use a wire brush on this cooler).
In areas with concentrated minerals in the water, change the water often to prevent high mineral content in the reservoir.
An inline water filter device, installed on the water line, will help keep mineral build up to a minimum.
Change the pads when they become mineral laden and dirty. In most areas, a set of pads will not last all season.
