Drainage And Exhaust Gas Ventilation - Priorclave Q63 Operation & Maintenance Manual

Priorclave Manual 27125322-EN Issue 2 06/06/2012
If not already supplied as a supplementary sheet to this manual separate instructions are
available by contacting Priorclave - service@priorclave.co.uk – making sure to include the
autoclave serial number in your correspondence.
If a cable and plug are not fitted then your Priorclave can be wired as shown in the diagram
below.
3 Phase - 10.5 kW Heating
The power supply should be a 3 phase and neutral isolated supply, rated at 15 Amps per
phase and connected to the isolator as in the diagram below. Sufficient length of cable should
be used to allow the autoclave to be moved if necessary and worked on from the back. The
cable used to the earth line and neutral feeds should be capable of carrying the per phase
amperage of the supply. The neutral line must be nominally at earth potential and must NOT
be fused. This equipment must be earthed.

Drainage and Exhaust Gas Ventilation

The various inlets and outlets are situated at the back of the autoclave and are labelled with
their individual functions. Within the space constraints of the autoclave cabinet, where
possible drains and inlets have been combined to reduce the number of connections required.
Please read the following guidance before proceeding with connection to drains and water
supplies.
General
Autoclaves used for processing laboratory waste must be provided with a drainage connection
as described below. This is a requirement of British Standard 2646. A connection will also be
required if the autoclave is fitted with any free-steaming or vacuum options as significant
amounts of steam will be released from the autoclave at different stages of the cycle. The
hazard groups below are as defined by the Advisory Committee on Dangerous pathogens as
published in Categorisation of Pathogens According to Hazard and Categories of Containment.
Extract from BS2646 Part 2 1990
7.2 Drainage system
"The drainage system from the autoclave should prevent dispersion of splashes and steam into
the working area. For autoclaves designed for a make-safe process, discharge should be
directed to a sealed discharge system; the system should lead by direct connection to a
building drain or catchment tank.
An open tun dish is not suitable for the discharge line of a laboratory autoclave, which is to be
used for a make-safe process.
The sealed discharge system should be vented to a high level by a pipe not less than 30mm
diameter. The vent pipe should be directed outside the building. Steam should not emit from
the vent pipe."
