Thank you for selecting Cole-Parmer instruments for your
equipment needs.

Product Overview

Cole-Parmer's Low Cost Gravity Convection Ovens are
designed for use in hospitals, industry, and school laborato­ries—wherever there is a need for low-cost, yet reliable ovens
for drying, sterilization, baking, evaporation or similar type
work.

A hydraulic thermostat provides reliable temperature control
with a range from slightly above ambient to 210°C. A
sheathed heater is positioned in the bottom of the chamber
along with a constant-speed fan that circulates heated air rap­idly throughout the chamber. The metal cover shields the fan
and protects against splattering in the even that any material
is accidentally spilled in the area of the fan.

Chamber temperature is conveniently monitored via an LED
display on the control panel. To guard against overtempera­ture conditions, a factory-set hi-limit thermostat is an integral
part of the electrical system.

One-inch thick silica-based insulation in the double-walls of
the chamber helps retain chamber heat. The interior walls of
the chamber are stainless steel and the shelves are chrome­plated steel for ease of maintenance and clean up.

These ovens also have a steel exterior finished in baked
enamel and are rigidly constructed for long, trouble-free serv­ice.

Shipping Carton

The shipping carton 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

The oven should be located in an area free from drafts
and sources of heat, as well as allowing for natural air
movement to dissipate heat from the oven.

Leveling

The oven should be on a level surface, in order to facili­tate movement of materials into and out from the cham­ber.

Shelving

Slide shelves into place inside the oven and position
according to the height required for the items or materials
to be heated.

Electrical Requirements

The 120V unit is supplied with a 3-wire line cord with
molded plug. It should be plugged into an outlet designed
for 3-prong plugs. For an outlet designed to accept 2­prong plugs (ungrounded), it is required that a qualified
electrician replace the outlet with a new grounded type.

Unpacking and Installation

Warning

Do not place oven on or near any
combustible surface to avoid the pos­sibility of fire and resulting property
loss and injury or death to personnel.

Caution

Do not remove the rubber spacer feet.
Removal of the feet will prevent proper
air venting (air used to cool the elec­tronics is discharged out the bottom)
of oven chamber that may cause
excessive heat buildup on electrical
components and erratic control of tem­perature.

Caution

Bottom shelf is fixed in place to guard
against access to heater area and
possibility of injury. Do not remove bot­tom shelf unless performing mainte­nance or repair.
