Kastor Inferno Super Electrical sauna stoves - Manual (Page 10)

INFERNO SUPER 10
1. INTRODUCTION
We thank you for your confidence in this KASTOR product. KASTOR heaters are known to be long lived and of
high quality. We recommend that you – and the person installing this heater – read these instructions carefully.
This manual should be always close at hand when needed. Once the installation is completed, this manual should
be handed to the sauna's owner or the person responsible for operating it. Before you do anything, you should
read this manual and pay special attention to the “WARNINGS” part on page 12.
2. INSTALLATION
2.1. The Heater's Installation Location
The manufacturer's safe installation distances (table 3, page 5) must be adhered to. These distances are also given
on the heater's data plate. The attachment sizes for the wall mountings are shown in picture 1a. The walls next to
the heater and the roof above it must not be protected with additional paneling, as the temperature in the wall
material may rise to dangerous levels. This heater is not designed to be embedded or installed in an alcove.
2.2. Attaching The Heater to The Wall
For easier installation the heater is equipped with a detachable wall mounting (picture 1b) that can be attached to
the wall beforehand (picture 1a). You may use the included attachment screws for installation in a wooden wall.
A thin panel board is not sturdy enough for the attachment. You should strengthen it from the backside using
board or plywood. Use heat resistant attachments (wedge or hammerset anchors, no plastic plugs) for masonry,
brickwork or other stone walls. The heater is lifted into its place according to pictures 1c, 1d, 1e. Do not lift the
heater by its coils or the upper plate of the back casing. Use the lower rim of the inner casing with support from
the upper part instead. A free corridor should be left at one side of the heater for maintenance work.
2.3. Connection to The Power Grid
The heater's electrical installation must be performed by a certified electrician. Check the heater's technical data
prior to connection. The connection to the power grid may only be performed by a professional electrician who is
certified according to present regulations. The heater is connected semi-permanently to a connection box on the
sauna wall. The connection cord should be a H07RN-F (VSN, VSB) rubber cable or equivalent. Do not use cords
with PVC insulation. The connection diagram is attached to this manual (picture 7) and to the heater's connection
box. Do not attach the heater's power feed to the error current connector
. Remove the fuse, before detaching the
oven from the wall.
The connection is performed in the following manner before the heater is lifted into its place: 1. Remove the wall
mounting in the back of the heater, open the upper attachment screws at the sides and loosen the lower ones. 2.
Attach the throughput rubbers and cable grip. 3. Pass the cable through the throughput rubber to the connection
box. 4. Attach the cable to the cable grip and connector according to the connection diagram. 5. Provide
sufficient cable length to ensure that the cable does not run underneath the stone enclosure nor too close to the
heater's base plate. The heater's connector also provides for control of the electric heating (or the heater's signal
lamp). The package holds a second throughput rubber and cable grip with screws for this purpose. The control
cable's conducting material and diameter must be equal to the connection cable. The relay used in controlling the
electric heating gets a control voltage of 230 VAC from the heater. The conductors' diameters and numbers and
fuse values are given in the technical data table. The spray water tight connection box must not be attached more
than 50 cm above the ground.
2.4. Installation of The Sensor And Its Location on The Wall
The sensor is attached to the sauna wall on the heater's center line. If you wish to heat the sauna to higher
temperatures than usual, the sensor may be moved to the side according to table 1 and picture 2. Deviations
from the given measurements will cause fire hazards.
There are two alternatives for attaching the sensor to the wall. For surface attachment, the sensor's protective
cover is attached to the sauna wall (picture 3A). Attach the sensor to the cover and raise the cable grip strips at
the lower part of the cover. Bend the cable grip strips around the cable and bend the wings of the cover over the
sensor (picture 3B). For embedded installation, the sensor is attached directly to the wall (picture 3C).
