6 Commissioning
6.1 Commissioning the cold room
 Clean and air out the cold room after assembly
(sieheKap.„7Reinigung“aufSeite14).
The room is ready for operation.
 Observe the corresponding operating instructions
for commissioning the refrigeration unit.
 Dial the cold room down to the desired temperature.
 Make sure that the refrigerated goods are only
placed in the cold room once the desired tempera-
ture has been reached.
 Then double-check the temperature in the cold
room and correct the refrigeration unit regulator as
necessary.
 Have the pressure equalisation valve checked by a
specialised refrigeration contractor.
L
Permissible pressure differential in cold room max.
100 Pa
(1mbar).
 Check the function of the pressure equalisation
valve regularly.
 Make sure that the outlet of the valve is not covered
on the inside or outside (by refrigerated goods, for
instance).
7 Cleaning
DANGER!
Risk of death due to electric
shock!
f Before any cleaning work, pull
the power plug or shut off the mains
power and secure it to prevent it
from being turned back on.
L
Tecto cold rooms and deep-freezing rooms are not
watertight.
L
Observe industry-specic hygiene requirements.
L
Create hygiene plan depending on use and products
stored.
 Regularly
checkTecto cold rooms and deep-freezing rooms for
soiling after the initial start-up and clean as required.
Cleaning interval depends on:
degree of soiling
Surrounding conditions
 Do not use pointed or sharp-edged objects.
 Only have work for the mains connection and instal-
lationofprotectivemeasures(GFCIcircuitbreaker)
conducted by a specialised electrical contractor.
L
A device which simultaneously disconnects all non-
grounded conductors with at least 3 mm contact
opening width from the mains (plug connection or
2-pole switch) is to be installed in the supply line to the
junction box.
L
Wire type of at least H05VV-F3G1.5 or NYM-J 3x1.5
should be used, unless additional requirements call for
a higher-level type.
 Attach edge protection.
 Remove the cover of the junction box.
 Penetrate cable feed-through of the junction box
and insert the enclosed feed-through sleeve.
 Connect to on-site mains connection.
 Make sure that the connection line in the room area
islaidrmly.
 Seal feed-through sleeve of the junction box and
ceiling feed-through with suitable sealant.
 Switch on mains voltage and check the function of
the electrical system.
Only if the unit is not from Viessmann:
 guide connection line through room ceiling.
 Guide connection line through the feed-through
sleeve and connect to junction box at terminals L1,
N and PE.
Small thermostat in junction box for doors with heater:
activates the frame and valve heater at approx. 0
°C when the temperature drops.
deactivates the frame and valve heater at ap-
prox. 7 °C when the temperature rises.
 Observe the small thermostat’s hysteresis range
and tolerance.
L
The small thermostat will not activate the heater if the
junction box is on the warm side.
 Connect heater without small thermostats.
 Disconnect the heater when disconnecting the
system or when operating the room in the positive
range.
