MRC MSF 11-3 - Troubleshooting Common Furnace Issues

12
Before cleaning or sterilization (in addition to what is recommended by the manufacturer),
the user must make sure that his chosen method of sterilization and cleaning products will not
damage the equipment.
11. STORAGE
Store the electric Furnace in its packaging in a location that meets the following requirements:
- heated and naturally ventilated room with an ambient temperature ranging from +5 to +35C;
- atmosphere with sulphurous gas concentration not exceeding 0,13 mg/m³ and chlorine salts
concentration not exceeding 0,3 mg/m² per 24 hours;
- the ambient relative air humidity should not exceed 80 at the temperature of 25C.
During loading and unloading of the Furnace, protect it from any shocks.
12. TRANSPORTATION
The electric Furnace should be transported only in closed means of transport in which the
temperature ranges from - 50 to + 50C; at the temperature of +25C, the ambient relative air
humidity must not exceed 80.
You can transport the electric Furnace by any means of closed transport, but protect it from
any rough, jarring movements. The packaging does not protect the electric Furnace from the
effects of improper handling.
The chamber must be empty when the furnace is transported. Remove shelves, bottom
plates or container, etc. These accessories can cause severe damage to the furnace
13. WARRANTY
The manufacturer guarantees that the electric Furnace meets company standards.
The Furnace is guaranteed for 12 months from the date of purchase provided that the user
follows the instructions regarding the Furnace’s storage, transportation and usage. However,
the guarantee does not extend more than 24 months beyond the Furnace’s manufacture date.
Manufacture defects that appear during the warranty period shall be repaired at the
:manufacturer’s expense. The manufacturer’s address

14. TROUBLESHOOTING
Problem
Possible Cause
Solution
The Furnace doesn’t
turn on.
There is no rated power supply voltage;
The fuse is burnt out.
Check the power supply;
Change the fuse.
The Furnace doesn’t
heat up.
The temperature controller is not switched
on;
Damaged heating element;
Damaged thyristor relay.
Switch on temperature controller;
Change heating element;
Change thyristor relay
Heating time is longer
than expected.
Low voltage of the power supply;
Door does not maintain a hermetic seal.
Check the power supply’s voltage;
Tighten the door’s closure.
Temperature fluctuation
or large over-shoot of the
set temperature.
Temperature Controller requires control
terms tuning.
Perform an Auto-tune (AT) on the
temperature controller (look at
temperature controller instructions).
