Operation

4.

4.1 System Start-up

Step 1

Flush-out 8" Pipe and Black Poly Tank of any debris before filling with water.

Step 2

Prime pump with water.

Step 3

Turn on the electrical power and fresh water supplies.

Step 4

Activate the pump by setting the cooling thermostat below room temperature.

Step 5

Open the flow control valve at each cooling panel enough to completely saturate the pad material.

Step 6

Adjust the bleed-off valve to discharge water from the cooling system at a rate of 1 gallon per hour

per linear foot of cooling system. For example: The bleed off rate for a CB705EF system (70'L.)
would be 70 gallons per hour.

4.2 System Operation and Adjustment

Step 1

Set the cooling setpoint on the temperature controller as shown on your Munters Corporation ventilation

system drawing. If this is not available contact your Munters field representative for proper settings.

Step 2

Adjust the flow control valve at each cooling panel to give the pad material a "shiny wet" surface. Pad

material performs best when as much water as possible is used, but the flow should not be so great that
water falls from the material.

Step 3

If the pad material remains dry on one side (with fans running), even at full water flow, adjust the

distribution pipe so that the distribution holes are pointing towards the splash deflector.

Step 4

If water drips from the cooling panel's upper edge, the pad material may be loose in its frame. Correct this

by tightening the wing nuts on the front of the pad retainer to press it more firmly against the pad material.

Step 5

Water bleed-off is necessary to limit mineral deposits and other contaminants on the pad material by

assuring the continuous addition of fresh water. The rate of, 1 gallon per hour per linear foot of cooling
system, should be considered only as a starting point in determining the required amount of bleed-off. Due
to differences in water hardness, a trial and error process must be used to determine the correct rate for
your location.

22

After the cooling system has operated for a week or 2, the sump water may become discolored or a light

mineral coating may develop on the face of the pad material. If this occurs, increase the bleed-off rate
slightly and observe the tendency of the coating to increase or stabilize. If after an extended period of
time the mineral deposits become more visible, again increase the bleed-off rate.

Through this trial and error process a bleed-off rate will eventually be established at which the formation of

new deposits will cease. Slightly increase the rate from this point to compensate for fluctuations in water
hardness. The cooling system should now equalize and now more deposits should form.

5.2 Maintenance Checklist

!

WARNING

Do Not allow fi re, sparks,

welding or smoking near

dry pads

!

WARNING

Do Not apply unapproved

chemicals or commercial

water treatments to sump

or sump water

Follow the guidelines below to prevent early pad failure and to get the maximum life from
your pads.

1. Reduce the number of on-off cycles. Do Not use 10 minute cycle timers on pumps.

2. Shade the pads and sump to minimize algae growth.

3. Dry the pads out completely each night to kill algae. A 24 hour timer may be installed
to shut pumps off at 10 PM and not allow them to come on until after 9 AM.

4. Bleed-off some water continuously to prevent concentration of minerals and dissolved
chemicals in sump. Start with 1 gallon per hour for each linear foot of cooling system
and adjust as necessary.
