Apply CHLOR*RID DTS - Apply directly
onto the substrate. Sufficient product must
be applied uniformly across the substrate to
thoroughly wet out surface, with no areas
missed. This may be accomplished by use of
a pump-up sprayer or conventional spray
gun. The method does not matter, as long as
the entire area to be cleaned is wetted. After
the substrate has been thoroughly wetted,
the salts will be soluble and is now only
necessary to rinse them off.
Rinse - It is highly recommended that a hose
be used, as a pressure washer will damage
the fins. The water to be used for the rinse is
recommended to be of potable quality,
though a lesser quality of water may be used
if a small amount of CHLOR*RID DTS is
added.
Check with CHLOR*RID
International, Inc. for recommendations on
lesser quality rinse water.

Lubrication
All original blower motors and bearings are
furnished with factory lubrication. Some
applications will require that bearings be re-
lubricated periodically. The schedule will
depend on the operating duty, temperature
variations or other severe atmospheric
conditions.
Bearings should be re-lubricated when at
normal operating temperatures, but not
running. Rotate the fan shaft by hand and
add only enough grease to purge the seals.
DO NOT OVERLUBRICATE.
Recommended greases are:
SHELL OIL - DOLIUM R
CHEVRON OIL - SRI No. 2
TEXACO INC. - PREMIUM R
Phase and Brownout Protection
Voltage monitor should be wired according
to unit specific wiring diagram include in
the control compartment.
Before applying power to the unit the
voltage monitor should be set up. The three
knobs on the front of the monitor should be
adjusted.
Figure 24 - Voltage Monitor
Adjust the top knob labeled LINE VOLT to
the operating voltage. This should be the
operating voltage for the equipment and the
measured voltage on the single or three
phase lines.
Adjust the knob labeled %± to either
SINGLE PHASE on the left side of the dial
or 3 PHASE on the right side of the dial.
After selecting single or three phase set the
Blower wheels and bands must be
inspected for excessive dust build up
periodically and cleaned if required.
Excessive dust build up on blower
wheels may cause an unbalanced
state; leading to vibration and/or
component failure. Damages due to
excessive dust build up will not be
covered under factory warranty.
CAUTION
Electric shock hazard. Shut off all
electrical power to the unit to avoid
shock hazard or injury from rotating
parts.
