We therefore recommend you arrange a maintenance contract with your local

heating contractor.

Never treat appliance surfaces with scouring agents or cleaning agents

containing acid or chlorine.

For installation in Austria:

Observe the ÖVE regulations and requirements and those of your local

power supply utility.

Observethespeciedelectricalfuseratings(seeSpecication).

Only replace faulty components with original Wolf spare parts.

AnydamageorlossresultingfromtechnicalmodicationstoWolfcontrol

Thesemustbettedwithaatgasket.

- Thread-sealing connections (type R): Using too much sealing material (e.g.

hemp),resultsinexcessivestressontheconnection.Thiscanresultinthe

enamel cracking. Make sure the thread between cylinder connection and

pipework is fully covered.

- ThecoldwaterandDHWconnections maycontainplasticsleeveinserts.

These must remain in the cylinder. Do not pull them out before installation.

Whenselectingtheinstallationmaterialforthesystem,observeengineering

length above 4 m are notpermitted. The discharge pipe must be installed with

a fall. The drain pipe downstream of the tundish must have a diameter at least

twice as big as the valve inlet diameter. Place a sign close to the safety valve

discharge pipe with the following inscription:

The combination with Wolf heat pumps provides a variety of space-saving

installation options.

The Wolf WPM-1 heat pump manager with integral BM programming unit

is a required accessory for all heat pumps and cylinders. The cylinder

temperature sensor is available as a required control accessory.
