Device Introduction
Preheating furnace is useful for all of the thermal operations on
dental molded gypsum including removable prosthesis (cobalt
chromium) and xed prosthesis (porcelain), also in the other
laboratory and industrial uses (other than dentistry) are applied.
This electric furnace which is able to be planned and comput-
erized control is used in order to plan controllable thermal cy-
cles in thermal speed and adjustable temperature maintenance
time and to prevent any unscientic function.
In many cases, it can be seen that after the completion of the
work, plaster mold cracked or its precision has been missed.
This is due to the lack of accurate and programmable furnace
so that thermal shocks hit the mold. By using cylinder furnace,
the size and shape of the mold will not be changed either.
Advantages of the device:
1Programmable system and controllable with computer
2Controlling of temperature, time and speed of heating in 3 steps
3High speed and precision
4Setting the machine and the program will be performed in idle
time (programming the timer and performing the program
after 100 hours)
5Equipped with a warning system and technical
violation detector
6Equipped with an alarm system in different stages of
performance during programing
7Having10 memories for planning and implementing thermal
cycles. The information of the system would not be missed
in case of a power failure and power outages.

This is the most important part of the device for planning.
(3.2.2) the thermal graph:
Temperature Graph contains 10 parameters as follow:
1Timer: This parameter determines the time of starting the
furnace after nishing the intended time of the program from
the start which is adjustable in minutes and seconds.
2Heat Rate1: This parameter shows the warming speed
from the initial
temperature to Temp1 (It means that the furnace tempera-
ture will be increased at a rate of several degrees in °C or F
in minute.) So that whenever the number becomes larger, the
temperature speed will be faster.
3Temp 1: Adjustable and programmable temperature for the
rst stage of heating or the nal tempreture which is dened
according to different materials of different companies.
4Hold Time 1: The stop duration at temp1 which is
adjustable in minutes and seconds.

5Heat Rate2: This parameter is the heat increase rate of
the furnace temperature from Temp1 to Temp2.
6Temp 2: the programmable temperature for the second
stage of heating
7Hold Time 2: The stop duration at temp2
8Heat Rate3: This parameter is the heat increase rate of the
furnace from Temp2 to Temp3.
9Temp 3: the programmable temperature for the third stage
of heating
10 Hold Time 3: Duration of a stop at temp3
(3.2.3) function keys:
POWER: To connect and disconnect the electric current.
(besides the device)
ON / Off: The ON key is to turn on and the Off key is to turn off
the device.
C / F: To convert temperatures from Celsius to Fahrenheit
and vice versa.
PROGRAM NUMBER: To select the program number
from 0 to 9.
PROGRAM EDIT: To view the parameters of the pro-
gram and to change and modify them.
CLEAR: To erase the wrong values that they have been
entered by mistake and to be used to turn off the alarm.
Key numbers: These keys are used to enter numbers
and the parameter values.

furnace.
TONE: To enable and disable the key sounds.
(3-2-4) Device Monitors:
Graphical Monitors: Actually, this curve is a thermal graph at
three stages. The process of planning and executing a thermal
cycle (heat functions) is shown on the monitor (by LED lights).
Digital Monitors: digital monitors on the left are to display the
values of temperature, time and speed of warming.And the
right monitor is to display the status of the furnace, the number
of programs, types of errors or defects (alarms).

Upon receiving the product, make sure it is intact. If there is any
damage or shortage of parts, inform Polaris Company and its
carrier.
It is recommended that the original box is kept because it is
needed for transporting the furnace safely. Also the box
ensures the claim that a safe box has been used during
transporting which prevents damage to the device.
Installation and Set up the Device
1Take out the device carefully from its package. To do this,
all of the surrounding protectors (EPS) are removed. Then,
bring it out by taking the “bottom” of the furnace.Put it on
the quite stable, at and standard laboratory table. It is bet-
ter to be a minimum 20 cm of empty space around the
furnace. Note that the base or the surface of the table should
not be made of metal.
If the base of the table is made of metal and in contact with
the ground, There will be a risk of electric shock. So make
sure your furnace is placed on a wooden or berglass table
one or make sure that the earth wire is connected to the
installation area.
2Make sure of the resistance of the surface below the device
against the heat. The surfaces sensitive to heat may lose
their color by heat.
3when there is not earth well, the earth wire of the
device can be connected to the nearest heater tube (if
it is made of metal) or water tube (if it is made of metal).
4Keep the device away from direct sunlight.
5Do not put objects or ammable substances next to the
device.

6While the device is working, do not put any object on the
ring chamber.
7Put the device in an appropriate place in order to prevent
any problem in turning on and off the device.
8The device is designed for indoor usage.
9The permissible environmental conditions: temperature 15-
40° C (59° F to 104° F), with a maximum rate of 75%
humidity.
