8 Before the use

Before operating the packheater the user has to make sure that the device is placed

on a horizontal, stable surface and that there is a distance of at least 8 cm to all

surrounding surfaces. All wrapping has to be removed. It is not permitted to deposit

any items on the device. This manual has to be kept nearby the device.

Attention: The device’s surface will be hot during operation!

9 Starting Up

9.1 Filling

After closing the outlet valve the packheater can be filled with tap water (no distilled

water, see chapter 11: Care, Maintenance and Disinfection). The minimal water-level

is 10 cm. The maximal level with heat packs may not exceed 3 cm under the upper

edge of the tub. Heating up heat packs is not permitted without using the insert grid.

Heat packs that touch the bottom of the tub may burn and stick to the stainless steel

surface. The water-level has to be controlled regularly.

9.2 Emptying

The packheater may be emptied through the outlet valve on the device’s front. Before

emptying, all heat packs have to be taken out. The water may be drained into a

bucket or, using the optional rubber hose, into a floor gully. Out of hygienic reasons a

fix connection to the sewage system is not permitted!

Attention: The water is hot! It bears the risk of scalding!

9.3 Starting Up

Attention: Before operating the packheater all legal safety instructions

according the valid accident prevention regulations have to be

respected.

1. The power supply has to fulfill all requirements on the identification plate.

2. The power supply cable may not be sharply bent or pinched. It may not touch

the surfaces of the packheater. During operation, the power supply cable may

not get moist or wet.

3. When all wrapping is removed, the packheater may be filled with water as

described above. The water-level has to be controlled regularly.

4. Switch on the main switch (picture 3).

5. The temperature is selected by turning the knob until the chosen temperature

shows to the reference point (picture 3). When the packheater is switched on,

the heating starts immediately.

Attention: if the device is operated without water, there will be danger

to both user and device! Damages caused by dry running will lead to

the loss of guarantee.

Attention: Before a heat pack is applied to a patient, the temperature

has to be controlled with an adequate thermometer!

9.4 Safety Installation

The packheater is protected against overheating by a safety temperature limiter.

When activated, the temperature limiter switches off the device permanently.

Operation will be possible again after the packheater has cooled down to room

temperature and the limiter has been reset manually after consultation with the

manufacturer. If this safety installation was activated, contact the service of your

dealer or the manufacturer before you operate the water bath again!

In case of a short cut or an overload the packheater is disconnected from the power

supply by two device fuses. They are located on the back side of the device nearby

the power connection (picture 4). Before replacing a blown fuse, the power plug of

the packheater has to be pulled. Blown fuses may only be replaced by fuses of

exactly the same type (see chapter 16.1 Technical Data). If this safety installation

was activated, contact the service of your dealer or the manufacturer before you

operate the packheater again!

10 Daily use

Attention: The packheater has to be supervised, while it is operated.

The use of a time switch or remote control is not permitted!

For a well-organized daily use of the packheater we give the following non-binding

recommendations:

 Heat packs are medical products with an own operating instruction. All

declarations of this operating instruction have to be followed when treating a

patient.

 At closing time the water-level of the packheater has to be checked and

corrected if necessary. As an unsupervised operating is not permitted, the

packheater has to be switched off overnight and on weekends.

 Before the first treatment of a patient on a new day an appropriate time for

heating up has to be taken into account.

 The temperature of the heat packs may vary from the temperature of the

water. It has to be controlled with an adequate thermometer before applying a

heat pack to a patient.

11 Care, Maintenance and Disinfection

For care and maintenance of the packheater the national rules and guidelines

concerning the operation of devices in health care facilities have to be obeyed.

11.1 Water Change

For hygienic reasons the water in the packheater has to be exchanged completely at

least once a week by tap water.

Attention: Don’t use distilled water!

Due to its chemical structure distilled water is aggressive against metals and may

cause corrosion at areas where the original surface of the stainless steel has been

modified (e.g. welding seams).

11.2 Removal of Deposits

Stainless steel needs caring if its corrosion resistance shall be preserved.

Prerequisite for corrosion resistance is the access of oxygen from air or water to the

metallic surface. If deposits are forming on the stainless steel (especially lime

deposits), the access of oxygen is inhibited and corrosion may occur. Therefore the

tub and the insert grid of the packheater must be cleaned regularly and treated with a

stainless steel polish. This kind of polish contains ingredients that delay the forming

of new deposits. Avoid scouring sponges (especially metallic sponges and steel

wool), scouring powder or other abrasive agents. They cause scratches in the

surface which induce increased staining.

When water is heated, dissolved lime builds white or brownish (not to be confused

with rust!) deposits. They have a porous surface where bacteria may settle.

Therefore deposits have to be removed regularly.

11.3 Cleaning of the External Surfaces

Cleaning and maintenance of the external surfaces may only be performed with a

moist, lint-free cloth. Liquid remnants (cleaning agents, water) have to be removed

immediately.

11.4 Cleaning of the Tub and the Insert Grid

For hygienic reasons the water in the packheater has to be exchanged completely at

least once a week by tap water (don’t use distilled water!). At this occasion calcium

and dirt deposits have to be removed with standard cleaning agents. Using a

standard stainless steel polish helps protecting the stainless steel surfaces against

new deposits. Avoid scouring sponges (especially metallic sponges and steel wool),

scouring powder or other abrasive agents. They cause scratches in the surface

which induce increased staining.

Attention: Tap water with very high lime content may require shorter cleaning cycles!

At periods of standstill (weekends, holidays) the packheater should be cleaned and

left empty with opened lid. The more contact between oxygen and the stainless steel

surfaces the better is the corrosion resistance.

At the bottom of the tub of the packheater WB 4-30 there is a welding point visible

(picture 5). This welding point results from the production process of the tub and can’t

be avoided. It is no indication for a defect.

11.5 Recommended Cleaning Agents

 All-purpose cleaner / vinegar based cleaner / citrus based cleaner

 Stainless steel polish

Attention: Don’t use chlorous agents (i.e. bleaching agents) or silver polish.

11.6 Surface Disinfection

Recommended surface disinfecting agents:

 Biguamed Perfekt N, Hersteller Desomed –Dr. Trippen GmbH

 Cleanisept Wipes , Hersteller Dr. Schumacher GmbH

 Incidin Plus, Hersteller Ecolab Deutschland GmbH

 Mikrozid AF liquid, Hersteller Schülke & Mayr GmbH

 TPH protect, Schülke & Mayr GmbH
