Open all
>Drain valves<
[3], [4], [5]
by turning it counterclockwise (turn 90° left as far as it will
go). The thermal fluid will flow from the external application via the pump chamber and the
draining hose into the container.
Drain your externally closed application. The description for the drainage procedure can be
found in the documents you received with the application.
Open the connection
>Circulation flow<
[1].
Open the connection
>Circulation return<
[2]. Leave the temperature control unit open for a
while to dry out (without screw caps) and with
>Drain valve<
[4]) open.
4.4.2
Externally open application
Operating an externally open system without >Isolating sleeve< [27] installed
BURNS/FREEZING DUE TO OVERFLOWING EXPANSION VESSEL
Shut down the temperature control unit immediately.
Allow the thermal fluid to cool down/heat up to room temperature.
If the temperature control unit is installed below the open system, the thermal fluid will escape
from the
>Expansion vessel<
[18] and from the
>Sight glass<
[23].
If the open system is located below the temperature control unit, overflow can occur in the
open system.
Prior to starting up the temperature control unit with an externally open system, install the
>Isolating sleeve<
[27] (see page 24 in section
»Mounting/removing the isolating sleeve (op-
).
Close the
>Venting valve expansion vessel<
[21] for all stand-alone units by turning them
clockwise (turn 90° right as far as it will go).
4.4.2.1
Filling and venting externally open application
Non-compliance with the safety data sheet for the thermal fluid to be used
INJURIES
Risk of injury to the eyes, skin, respiratory tract.
The safety data sheet for the thermal fluid to be used must be read prior to use and its con-
tents respected.
Observe the local regulations/work instructions.
Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).
Danger of slipping through contamination of floor and work area.
Overflowing thermal fluid inside the temperature control unit
PROPERTY DAMAGE
If the temperature control unit is installed below the open system, the thermal fluid will escape
from the
>Expansion vessel<
[18] and from the
>Sight glass<
[23].
Shut down the temperature control unit immediately.
Isolate the temperature control unit from the power supply.
Have the temperature control unit only serviced and cleaned by staff trained by Peter Huber
Kältemaschinenbau GmbH.
Overflowing thermal fluid will create a film on surfaces, and therefore must be collected and dis-
posed of immediately after the event in accordance with the safety data sheet.
If this is not complied with is assumed that the temperature control unit does not comply with all
requirements of DIN EN 61010-2-010.
▪
During the fill process, ensure any necessary measures, such as earthing the tanks, funnels and
other aids, have been taken.
▪
Fill to the lowest possible height.
PROCEDURE
Open the
>Expansion vessel cap<
[22] and make sure that the
>Isolating sleeve<
[27] is installed
(see page 24 in section
»Mounting/removing the isolating sleeve (optional)«
). Then connect the
