2. INTRODUCTION

Accudry2 is an air-vented, reverse action, Standardised Tumble Dryer.
Accudry2 is engineered for laboratory stability tests. It is designed to reduce machine

variables and operator error to the absolute minimum.
The user can set the Controller to operate in English, French, German, Italian or Spanish.
The unit is equipped with a digital controller which displays both exhaust air temperature

and times for the heating and cooling periods. All relevant values are displayed
continuously throughout the drying cycle.

Opening the Tumble Dryer door interrupts the cycle and allows the operator to make an
interim examination of the load. Closing the door and pressing the START key allows the
cycle to continue from the same point.

At the end of the pre-set cycle time, an alarm sounds to alert the operator.
HEALINK – the Service and Calibration Division of Heal’s – offers a service and calibration

contract. Calibration covers the drum speed, the exhaust air temperature measurement
and digital timer.

Routine maintenance is confined to cleaning the easy-access lint filter at the front of the
drum.

WARNING !
To avoid a fire hazard, including spontaneous combustion, please read this
guide before operating the Accudry2 and observe the following safety
precautions at all times:

3. SAFETY

Installation

 This appliance is heavy. Care should be taken when moving it.
 It is dangerous to alter the specifications or attempt to modify this product in any way.
 Any electrical work required to install this appliance should be carried out by a

suitably qualified person.

 Care must be taken to ensure that the appliance does not stand on the electrical

supply cable.

 If the machine is situated on a carpeted floor, please adjust the feet in order to allow

air to circulate freely.

 This tumble dryer is designed to be vented through to the open air. It should have its

own ventilation system which should not be joined with any other ventilation system
or connected to any other appliance.

Correct use of dryer

 Clean the air filter before each use.
 Never allow the air inlet at the back of the dryer, the air outlet or vent hose to be

obstructed.

 Never direct the vent hose outlet towards the air intake at the back of the machine.

The machine must not recycle exhaust air.

 Never use the machine without the filter in position.
 Never exceed the maximum 6 kg load capacity of the machine (i.e., do not overload).
 Never place dripping wet items in the drum.
 Never use the dryer on a carpeted floor where the pile height would prevent air

entering the dryer from the base.

 Never tumble dry articles that have NOT been well washed in water and detergent

solution then well rinsed and spun.

 Never tumble dry articles contaminated with flammable substances.
 Ensure the dryer is installed in accordance with the Installation Instructions given in

this guide.

 Never tumble dry: rubber, foam rubber, plastic, plastic foam, nappy pants

or liners, polythene, paper, dry cleaned garments, large or very bulky
items including duvets and sleeping bags. Items not recommended for
tumble drying may be marked with a symbol such as:

Stainless steel top

The stainless steel surfaces must not come into contact with liquid cleaning and
disinfecting agents which contain chlorine or sodium hypochlorite. These agents can have
a corrosive effect on stainless steel. Aggressive vapours containing chlorine can also be
corrosive. Do not store containers of these agents on or near the machine.

Lint

Accumulated lint in the dryer can become a fire hazard, it also reduces the efficiency of the
dryer by causing longer drying times and increased power consumption.

 Clean the lint filter before every use.
 Ensure the area around the dryer is clear of lint.
 At regular intervals have the interior of the dryer casing cleaned of any accumulated

lint. For electrical safety, this must be done by a suitably qualified person or an
Healink Engineer.

Technical safety

 Before setting up the machine, check it for any externally visible damage. Do not

install or use a damaged machine.

 Before connecting the machine, ensure that the connection data on the data plate

(voltage and connected load) match the mains electricity supply. If in any doubt,
consult a qualified electrician.

 The electrical safety of this machine can only be guaranteed when continuity is

complete between it and an effective earthing system which complies with local and
national regulations. It is most important that this basic safety requirement is present
and regularly tested, and where there is any doubt, the on-site wiring system should
be inspected by a qualified electrician. The manufacturer cannot be held liable for
the consequences of an inadequate earthing system (e.g., electric shock).

 Do not connect the machine to the mains electricity supply by an extension lead.

Extension leads do not guarantee the required safety of the machine (e.g., danger of
overheating).

 The machine is built in accordance with current safety requirements. Unauthorised

repairs could result in unforeseen dangers for the user, for which the manufacturer
cannot accept liability. Repairs should only be undertaken by an approved
technician. Ensure electricity is not supplied to the machine until after maintenance
or repair work has been carried out.

 In the event of a fault or for cleaning purposes, the machine is only completely

isolated from the electricity supply when it is switched off at the wall socket and the
plug is withdrawn, or it is switched off at the mains, or the mains fuse is withdrawn.

 Faulty components must only be replaced by genuine original spare parts. Only

when these parts are fitted can the safety standards of the machine be guaranteed.

 In countries where there are areas which may be subject to infestation by vermin,

pay particular attention to keeping the machine and its surroundings in a clean
condition at all times. Any damage which may be caused by vermin will not be
covered by the machine guarantee. Keep the dryer door closed when not use. The
end of the venting hose should be covered with a weather cap and terminal guard or
grille to prevent vermin from entering. Do NOT cover the end of the venting hose
with cloth/fabric of any description which may collect lint and block the exhaust vent.

4. INSTALLATION

Packaging

The transport and protective packing has been selected from materials which are
environmentally friendly for disposal and can normally be recycled. Ensure that any plastic
wrappings, bags, etc. are disposed of safely and kept out of the reach of babies and young
children. Danger of suffocation. Rather than just throwing these materials away, please
ensure they are offered for recycling.

Unpack the Accudry2 Standardised Tumble Dryer carefully and check that the following
accessories have been supplied:

 Accudry2 Standardised Tumble Dryer
 Venting Hose
 Operator’s Guide You will find these items inside the drum
 Quick Start Guide

Do not dispose of any packaging until the instrument has been found to be in good
condition, correctly installed and operating correctly.

Location

Ensure electrical power is not supplied to the appliance while installation work is being
carried out.

Make sure the dryer door can be opened without hindrance after installation.
When operating the tumble dryer, the room temperature must not exceed 35°C, as it may

affect the performance of the dryer.
When moving the machine, you can hold it by the lid where it protrudes to the rear of the

dryer. To manoeuvre the dryer out of its packaging to its installation site, you will also
need to hold it by the front feet.

A ventilation gap of 10 mm must be maintained between the base of the machine and the
floor. It must not be blocked by deep pile carpets, plinths, etc, which would prevent a
sufficient intake of cool air.

Whilst drying, the tumble dryer will expel a certain amount of warm, very moist air
containing fibre particles, and this should be removed from the room as quickly as possible
to prevent condensation. In general, it is better to carry the dryer's exhaust outside via the
100 mm diameter flexible hose supplied with the dryer; ending permanently at a fixed
weather cap and terminal guard or grille, fitted to an exterior wall. The tumble dryer must
be installed in a clean place, where dirt does not build up. Make sure there are no
obstructing items or material near the air-intake vents provided at the back.

Levelling

Figure 1: Adjust the levelling feet

Figure 2: Checking with spirit level

To keep vibration and noise to a minimum when the dryer is in use, it should be placed on
a firm, level surface. The machine must be perfectly level to ensure safe and proper
operation.

Once in its permanent operating position, check that the dryer is absolutely level with the
aid of a spirit level. If it is not, raise or lower the two adjustable feet at the front of the
machine until it is.

The feet must never be removed. Do not restrict the floor clearance through deep pile
carpets, strips of wood or similar. This might cause heat build-up which would interfere
with the operation of the appliance.

Venting

Figure 3: Vent ring nut

Figure 4: Draining hole

To simplify the installation, there is a choice of vent outlets: one at the back, the others in
the left and right-hand side. Connect the hose to whichever is the more convenient by
pulling the ring nut (A) from the vent outlet at the back, screwing it on to the hose and
pushing it firmly back into place. The unused vents should be sealed with the special snap
covers provided.

The exhaust air must not be vented into a chimney or vent flue which is in use, nor should
it be connected to ducting which ventilates rooms with fuel burning appliances.

If the hose is long and the room temperature low, moisture may condense to water inside
the hose. To prevent this water from lying in the hose or flowing back into the tumble
dryer, it is advisable to drill a small hole (approximate diameter 3 mm) in the lowest point
of the hose and to place a small collecting container below it. (See Figure 4, point B).

Once connected to the dryer, run the vent hose to the desired outlet point, ensuring that
the overall length is less than 2 metres, and that it contains no more than two (2) bends.

In order to prevent the tumble dryer from overheating, it is important that the exhaust is
unobstructed. Therefore, in case of a permanent hose fitted to an exterior wall, it must be
ensured an exhaust capacity of at least 150m3/h.

Ensure that the vent hose is not obstructed or compressed. If the hose is partially
obstructed, drying efficiency will be reduced, resulting in longer drying times and higher
energy consumption. If the hose is completely obstructed, the safety cut-outs within the
machine may operate.
