UTR-20 Assembly Instructions

UTR-SERIES TRACKER TROUBLESHOOTING

TRACKER SITS LEVEL, LEANS TO ONE SIDE, OR DOES NOT MOVE:

1. Manually move tracker through its entire range of motion. Check for any mechanical interference and

correct if necessary. You MUST grease the bearings regularly, AT LEAST TWICE A YEAR (See

warranty).

2. Check shadow plates for proper installation. The tracker will NOT work WITHOUT them.

3. Be sure the Track Rack™ is pointing south (in the Northern Hemisphere), the copper transfer tube is

mounted on the south end of the frame and the tube is not crimped in any way.

4. Check for any wiring which may stop the Track Rack™ from turning freely. Check wiring and junction

boxes for equal balancing on the east and west sides.

5. A shock absorber may be sticking. On a calm sunny day remove the shock from the top rail. If it tracks

without the shock, call ZOMEWORKS. The shock absorber may be defective. (SHOCKS ARE

WARRANTED FOR 2 YEARS ONLY)

6. The Track Rack™ moves when sunlight warms one canister, which then forces refrigerant into the cooler

canister. You may simulate the sunlight’s effect by warming the lower canister with a hair dryer or

carefully with a hand torch (Alternately, you may also cool the upper canister with wet towels or a cold

water spray). Within 10 minutes, the Tracker should begin to rotate towards the cooler canister. If the

Track Rack™ does not move, and you have checked the assembly for movement, the Tracker may have lost

its charge. Call your dealer or your ZOMEWORKS representative.

TRACKER IS SLOW TO WAKE UP:

1. Check that Track Rack™ is getting full early morning sun shining underneath the tracker. The canisters

must “see” the sun.

2. Check modules and electrical junction boxes for equal balancing on the east and west sides.

3. Check bearings for lubrication so the tracker moves freely.

NOTE: IF THE TRACK RACK™ IS INSTALLED IN A CORROSIVE CLIMATE, CHECK THE

AXLE AND BEARINGS FREQUENTLY FOR RUST OR CORROSION; YOU WILL NEED TO

GREASE YOURS 2 - 3 TIMES PER YEAR. COATING THE AXLE AND BEARINGS WITH

GREASE WILL HELP PREVENT CORROSION.

4. The shock absorber may be sticking when collapsed or extended. Remove the shock bolt at the top rail and

check the shock motion for “stick”. If the tracker “wakes up” without the shocks, the shocks are likely

defective. Contact your dealer or ZOMEWORKS for replacement. DO NOT LEAVE THE TRACKER

DEFENSELESS WITHOUT SHOCKS; A STRONG WIND COULD DAMAGE IT. TIE IT DOWN.

TRACKER DOES NOT HIT THE BUMPER STOPS:

1. The tracker is very effective even if it doesn’t track to the bumper limits. The bumper stops are set for

approximately 90° of rotation.

2. To increase the rotation, raise the counterweight. But remember: raising the counterweight will make the

tracker less stable in the wind. For optimum performance you must balance rotation against stability. If the

tracker rotates further to one side than the other, the tracker may be out of balance, refer to Step 11 of the

instructions and rebalance the rack.
