1 FORWARD
Thank you for purchasing NovaLynx products. NovaLynx has been designing and manufacturing
weather instruments since 1988. NovaLynx represents several well-known brands of quality
manufacturers, including Gill Instruments, RM Young, Kipp & Zonen, and Vaisala. It is our hope that our
products will meet all your monitoring requirements.
2 INTRODUCTION
The 255-620-A Evaporation Pan Automatic Refill System is designed for use with the NovaLynx
255-200 Class A Evaporation Pan and 255-100 Analog Output Evaporation Gauge. When used together
with a monitoring system (logger), a fully-automated evaporation monitoring station can track
evaporation without daily visits to the site to take manual readings.
The automatic refill system consists of a programmable timer and float valve. The programmable timer
starts the refill cycle, while the float valve cuts off the water when the maximum fill level is reached.
After a few minutes the timer shuts off its internal valve to ensure that no more water is added. The
cycle repeats (usually after an interval of a week).
The refill system can operate over a wide range of inlet water pressure: 14 to 690 kPa (2 to 100 PSI).
The system should not be used in applications where the temperature will drop below 3°C (37°F)
because freezing could damage the valve. Where freezing weather is expected, the system should be
removed, drained and stored indoors. For long-term storage, the batteries should be removed.
The timer is supplied with the battery installed. Instructions for battery replacement are included.

4 PROGRAMMING
The ideal depth of water in an evaporation pan, for consistency, is between 2 and 3 inches below the
rim (i.e. 7" to 8" deep). Experiments have shown that the height of the rim of the pan above the water
surface affects the rate of evaporation. In order that the records from all stations will be comparable,
the pan should be filled to a level 2 inches below the rim, and refilled when the water has receded 1
inch (3 inches below the rim).
The automatic refill system operates close to this ideal, but some variance will occur due to mechanical
limits, water pressure variations, and differing rates of evaporation. The timer unit must be
programmed to suit the average of the environment where the evaporation pan will be used. Under
conditions of moderate rates of evaporation (~0.14"/day), the refill cycle can be set to repeat once a
week. Where evaporation is more rapid, the cycle may need to occur more frequently. If the average
rate of evaporation is known, one can approximately calculate how long it will take for the level to
drop an inch in the pan, and set the refill timer accordingly.
Instructions for setting and maintaining the timer is attached as an Appendix. Please set the following
parameters:
EXAMPLE
1. Current Time Set local time (using military time) HH:MM
2. Program 1
1st Opening Set a start time 07:00
1st Closing Set the stop time (= start + 10 minutes) 07:10
Note: Increase the stop time if needed for low pressure systems.
3. Program 2 Do not enable program 2
4. Weekly Program Select a day of the week Day 1
5 OPERATING CYCLE EXAMPLE
1. At the programmed time (7:00 am), the timer will open its valve and water will begin to fill the pan.
2. When the pan fills to about 9 inches deep, the float valve will stop the flow of water.
3. After 10 minutes (7:10 am) the timer will close its valve to stop the cycle.
4. One week later the cycle will repeat.
NOTE: The 255-200 Class A Evaporation Pan is 10 inches deep. When the automatic refill system is
installed on the rim of the pan and the water turned on, the pan will fill to a depth of 8.5 to 9.5
inches, depending on the water pressure. An inch of water is approximately 8 gallons.

6 ASSEMBLY AND INSTALLATION
The programmable timer connects to the float valve by means of a quick-connect hose fitting. Simply
align the two parts, and press firmly together. You should hear a "click" when the orange collar on the
fitting snaps into place. The fitting can swivel, making it easy to see the face of the timer when it is
installed on the evaporation pan.
Not Connected Connected
If it is necessary to remove the timer from the float valve, grasp the orange collar and push it down
toward the float to release the quick-connect fitting.
The float housing has two screw-type clamps. Open the
clamps, place the float housing on the inside of the pan so
that it rests on the clamp arms, then tighten the clamps. The
assembly should be firmly attached to the evaporation pan.
Connect a garden hose to your water supply and flush the
hose to ensure no debris will get into the timer. Attach the
hose to the 90° elbow on the top of the timer housing. Turn
on the water supply.
Operate the timer in manual mode in order to bleed air out of
the system. It will run water for 15 minutes and stop. This will
probably not fill the pan completely, but for the moment
leave it as is. After another 15 minutes or so, come back to the
pan and check for leaks. There should be no water dripping
into the pan. If there is a leak, check your connections.
When satisfied that there are no leaks, operate the system manually until the pan fills to the
appropriate level.
