Shipping Carton

This should be inspected upon delivery. When received,
carefully examine for any shipping damage before
unpacking. If damage is discovered, the delivering carrier
should both specify and sign for the damage on your copy
of the delivery receipt.

Open the carton carefully making certain that all parts are
accounted for before packaging materials are discarded.
After unpacking, if damage is found, promptly report it to
the carrier and request a damage inspection promptly.

IMPORTANT: Failure to request an inspection of damage
within a few days after receipt of shipment absolves the
carrier from any liability for damage. You must call for a
damage inspection promptly.

Location

Locate your unit in the most convenient place and near a
grounded electric outlet. If units are placed on a counter-
top, the front should be 3" or more back from the edge to
avoid accidental tipping of the unit.

If possible, locate your unit out of direct sunlight and away
from heat sources such as a radiator, stove or heat duct.

Clearance

Position the unit so that there is a

minimum

clearance of

12” on the top,

minimum

of 3” at the back, and

minimum

of 2” on each side. It is recommended that even more
space be left at the back of the unit in case maintenance
is required.

Leveling

This unit must be level. Rotate the leveling screws, locat-
ed under the front corners of the unit, until the unit is
level. If the floor is seriously out of level, you may need to
shim the corners with thin sheets of metal.

Unpacking and Installation

Warning

Unless unit is specifically designed for
combustible or flammable atmos-
pheres

DO NOT

use in the presence

of flammable or combustible materials
or explosive gases.

DO NOT

use in

the presence of pressurized or sealed
containers - fire or explosion may
result causing death.

Warning

DO NOT heat any substance above a
temperature that will cause it to emit
toxic fumes. Death or severe injury
may result.

Caution

Before connecting the final power sup-
ply, check the electrical characteristics
of the unit nameplate to see that it is
in agreement with the power supplied.
In addition, power should be wired to
the unit according to the electrical
schematic and all applicable codes.
Only qualified electricians should work
on the electrical portion of any unit
installed.

Caution

Solutions used to clean coils or neu-
tralize bacteria growth must not be
corrosive to metals (enamel-coated
steel) and materials used in the main-
tenance of this equipment - damage
can result: use a soft cloth and warm
water to clean.
