II. Safety
IMPORTANT Safety Items to be Observed.
Safety Warnings
! DANGER (may cause serious damage to property and or casualties)
1. The vacuum oven must be grounded reliably and away from any electromagnetic
interference sources (cannot be grounded or neutral).
2. Please confirm that the voltage and frequency of your power supply matches the
specified voltage and frequency advised prior to use.
3. This vacuum oven should be operated on an independent power outlet and always verify
that the plug and socket are well-grounded.
4. Do not allow the vacuum oven to be plugged in or unplugged without firstly ensuring to
turn off the main power switch.
5. It is not permitted to lengthen, reduce or cut the power connection cord to the product.
6. Do not bake or dry any flammable, explosive, volatile, or corrosive substances in this
vacuum oven.
7. When working at temperatures above 80 °C do not touch the door, inspection window, or
surrounding surfaces of the product to prevent burns.
8. Repairs must not be carried out without prior authorization. Repairs should be
commissioned only via repair qualified and accredited professionals.
! WARNING (may cause property damage or personal injury)
9. You must read and understand all the instruction manual details for this product prior to
operation.
10. The 304 stainless steel liner is not acid resistant, please adhere to advised anti-
corrosion measures and never use acidic media within the oven.
11. Use a power outlet with a grounding wire to prevent electric shock. If the power outlet is
not grounded, a ground wire must be installed by a qualified engineering technician.
12. When pulling the power plug out from a power source, do not pull out using the power
cord directly.
13. The power plug of the vacuum oven must be ‘unplugged’ in the following instances:
•Prior to replacing the fuse tube
•In the event of a failure or breakdown an inspection or a repair is required
•When not in use for a long period
•When moving or relocating the vacuum oven

User Manual
Version 1.0 8
14. When the vacuum oven is turned on, the upper deviation alarm function must be
adjusted or confirmed.
! ATTENTION (may affect operational performance or service life)
15. Always place the vacuum oven on a hard, firm, and level surface.
16. Do not allow the door to open or close via gravity only. Always guide the door to avoid
product damage or potential injury.

III. Vacuum Oven –Introduction
3.1 Overview
The Hephaestus V900 vacuum oven is designed to efficiently process raw materials in a
temperature controlled vacuum environment. It is ideal for research, pilot process development
and production. This process has the following advantages:
•Lowers the drying temperature due to low pressure.
•Prevents damage caused by dirt.
•The reduced processing temperature minimizes the oxidation rate of the product
ensuring less oxidative damage.
The Hephaestus V900 vacuum oven has an inner chamber, a vacuuming system, and a
temperature-control system.
The inner chamber of the vacuum oven is constructed from high-quality 304 stainless steel and
the exterior surface of the vacuum oven is polymer-coated. The inner chamber uses either a
galvanized or stainless-steel armor plate. Fiberglass insulation is used to thermally insulate the
chamber.
The chamber door has a viewing window that allows visual inspection of the process. The
window is constructed using a double-layered fortified glass design. The door uses a heavy-duty
column door pin. The door frame uses an airproof rubber seal to prevent vacuum leaking when
closed.
Note: The rubber airproof seal is not oil-proof.

3.2 Cautions
•The shell of the vacuum oven inner chamber should be grounded to ensure safety.
•The vacuum oven should be placed in an environment with less than 85% humidity
level. Ensure that there is no strong electromagnetic fields or vibration source nearby.
•The vacuum oven is not explosive proof or corrosion proof. Combustible materials and
corrosive liquids or gases should not be placed in the vicinity of the drying chamber.
•To maximize the lifespan of the vacuum pump, do not use it for a prolonged period.
•When the chamber reaches the required vacuum, switch ‘OFF’ the vacuum pump first
and then switch ‘OFF’ the power of the vacuum pump.
•If the product is excessively damp before drying, add a “precipitation” filter between the
vacuum pump and the cabinet to avoid steam entering the pump.
•If the material for drying is light and/or small in size (e.g. grains) a net should be used
in the mouth of the vacuum pump inside the chamber to prevent any grains from
getting into the pump and causing damage to the electromagnetic valve.
•If the air release rubber stopper becomes difficult to turn, Vaseline may be used to
lubricate the contact area.
•The vacuum chamber should be always clean. The glass on the Inner chamber door
should NOT be cleaned with any chemical solutions and should only be cleaned using
a soft cotton cloth.
•Whenever the vacuum chamber is not used for a prolonged period of time, it is
recommended that all exposed plated parts be cleaned by a nonabrasive lubricant. It is
recommended that a plastic film cover be placed over the cabinets to prevent dust
from accumulating.
