WARNINGS AND SAFETY RULES
!
INTRODUCTION
Evaporative cooling works on the principle of heat absorption
by moisture evaporation. Simply put, heat is removed from the
air as water evaporates. You feel this principle in action when
you step out of a swimming pool or shower; you feel immedi-
ately cooler as water evaporates from the surface of your skin.
Your evaporative cooler works on the same principle. Hot out-
side air is pulled through water-saturated pads, where the air is
cooled by evaporation and then discharged from the cooler.
WARNING…
To r duc th risk of l ctric shock, fir or injury:
• Read instructions and labels carefully.
• Always unplug the electric cord to your cooler before
you work on the cooler.
• Your cooler will run on 120 Volt AC, 60 Hz (cycle)
current only.
• Plug into three-prong grounded GFCI protected
electrical receptacle only.
• Do not operate if plug or cord are damaged in any way.
• Do not step on or roll over power cord with heavy or
sharp objects.
• Do not operate unit unless all panels are securely in
place.
• Remove the plug from the electrical receptacle by
pulling on the plug and not the cord.
• Test the GFCI receptacle or breaker monthly to ensure
it is functioning properly.
• Do not operate near open containers of flammable
liquids or gases.
• Never wash your cooler cabinet with a garden hose;
water may harm the motor and pump.
• If the unit is damaged or it malfunctions, do not contin-
ue to operate it. Refer to the warranty or troubleshooting
section at www.impcollc.com

Unpacking th Mobil Symphony. The unit is shipped with the casters
(wheels), grille and the top tray inside the cabinet.
Grill Installation. Before attempting to use your new Mobile Symphony
cooler you must complete the grille installation.
Attaching th plastic tray. Remove the side pad frames from the cooler
by lifting them up and out of the cooler cabinet. Locate the parts bag in the
cooler and attach the tray top using the push rivets provided. (Picture 1)
Installing th cast rs. Some models ship with the wheels already
attached to the cabinet bottom. If wheels are not attached then locate the
wheels inside of the cooler and attach them to the cabinet bottom using the
bolts included.
Installing th grill . Refer to the installation instructions in the grille bag.
Installing th drain bushing and standpip . Refer to Figure 2 and
install the drain bushing and standpipe through the hole provided in the bottom of
the cooler.
Installing th float valv and adapt r. Refer to Figure 3 and attach the
float to the side leg of the cooler using the hole provided. The garden hose
adapter attaches to the brass inlet fitting on the float valve. (Picture 2). Verify
that the hose washers are properly in place. Position the pump snug to blower
housing to prevent contact with the pads.
Conn cting to Wat r . Move the cooler to an area where it can be filled
with water and drained. The cooler should be located on level ground.
Connect to a water supply using a commercial grade garden hose (supplied by
customer) connected to the adapter on the float valve and turn on the water.
Verify water tight connections by visually examining both the float / hose con-
nection and the drain plug. (Picture 2)
CAUTION: Wat r inl t pr ssur should b limit d to a
maximum of 105 PSI or an inlin pr ssur r gulator
should b install d.
Adjusting th wat r l v l.
Refer to Figure 3 and set the water height as
shown by adjusting the float.
Conn cting to a Pow r Supply. Plug the grounded plug directly into a
120 Volt AC 60 Hz grounded GFCI protected electrical power sup
ply. Note:
Improper voltage will burn out the motor and pump windings and will void the
warranty.

Always make sure the unit is operated on a level surface. When
using indoors, the best location for it is near a partially opened
window or door where hot outdoor air can be drawn into the
unit. This cooler is portable, but use caution when rolling the
unit to avoid splashing and spilling of water. Cool air can best
be directed through the space by using a partly opened window
or door, ideally one that is situated on the opposite side of the
space from the cooler. This allows the cooled air to be moved
through the space and exhausted back outdoors which is
critical to proper performance of the cooler.

USE & OPERATION
CLEANING & MAINTENANCE
!
P riodic Drying of Pads. For best results allow pads to
dry after each operation by turning off the pump 15 minutes
before turning off the fan blower motor.
P riodic Draining of Sump. The entire water sump
should be drained at least once weekly to reduce mineral build-
up. The failure to regularly drain the entire water sump will
greatly increase the mineral deposits and reduces the expected
life of the cooling pads. This could result in early replacement
of the pads at the owner’s expense. Use a damp cloth and wipe
off any mineral deposits that appear outside or inside the unit
at least once per week of use.
Lubrication. The pump and blower motors do not require
lubrication. For belt driven blower wheel models only, the
blower shaft bearings need periodic lubrication. The oil cups
on the blower shaft bearings should be filled with a good grade
SAE20W or 30W oil when necessary. Under normal use, oiling
is required every three months of operation. DO NOT OVER OIL.
Cl aning Wat r Pump. (Pictures 5 and 6) Disassemble
and clean the water pump as follows.
• Disconnect power supply to the cooler.
• Access the pump by lifting the pad frames up and out of
the cooler. Remove pump from cooler.
• To prevent breakage, carefully release the four snap-out
tabs and lift impeller base plate from the pump body.
(Picture 5)
• Use a mild detergent solution and wash all deposits from
the inside around the impeller and impeller base plate.
• Spin the impeller to dislodge any foreign material.
(Picture 6) Rinse and reinstall impeller base plate.
• Reinstall pump into the cooler.
CAUTION
Do not allow th pump to fall ov r and
b com subm rg d in th wat r. Wat r
will damag th pump motor.
1. Turn on the water supply to the cooler. The hose concection
to the float valve provides an automatic method of refilling
the water supply as water evaporates.
2. For best results, turn the pump on a few minutes before
turning on the blower fan. This allows the cooling pads to
pre-wet for best efficiency.
3. When cooling is not required you can operate the unit as a
fan by turning on the blower fan only and leaving the pump
turned off.
4. The water can be adjusted by tightening or loosening the
clamp that pinches the water supply tube. Adjust the water
flow clamp so that adequate water is supplied to the pads
without excess water splashing out of the trough during
normal operation.
CAUTION
Do not op rat th unit with pads or
grill r mov d.
CAUTION
Unplug th l ctrical cord to th cool r
b for att mpting to work on or s rvic
th cool r.

Electrical wiring on your unit is not required as the unit has
been wired at the factory. For your future reference, the wiring
diagram in Figure 7 shows rocker switches, two-speed motor,
capacitor and pump.
The cooling pads should be replaced with fresh aspen fiber
at least once a year, at the beginning of each cooling season.
The need to change pads varies with locality and how much
dust, alkali and other foreign matter accumulates in pads. If
cooling efficiency is impaired, it may be desirable to change
pads several times during a cooling season.
Replacement Instructions:
To remove pad assemblies from the unit, lift up, pull out and
then down. Lay the metal side down on a flat surface and
remove the pad retainers. The aspen filters can now be removed.
Rinse off pad assembly, then install new aspen filter and retainer.
Replacement filter pads are available at your cooler dealer.
