Delfield T40 - Manual (Page 6)

2.6 Condensate drainage connection
For models T20C-T24C-T40 fit a condensate
water drainage hose with a minimum diameter
of 1” . Provide a waste pipe with a trap with a
diameter of at least 1 1/2” at floor level.
2.7 Information for the installation technician
Before starting up the machine, check that it has
been correctly installed.
1. Check that there are no gas leaks from weldings
or joints made during installation works.
2. Check that the pipes connecting the condenser
to the remote condensing unit have been well
insulated.
3. Check all wiring connections.
4. Check electrical input.
5. Check the standard pressure in the refrigerant
system.
6. Perform at least one blast freezing cycle (to the
SET temperature) and one manual defrosting
cycle. In the event that the appliance or
the remote condensing unit have not been
transported in a vertical position (e.g. on
the back) or have been overturned during
installation works, allow at least 4 hours before
starting up the equipment.
2.8 Safety and control systems
• Door microswitch: shuts down fan operation in
the cell when the door is opened.
• General fuses: protect the power circuit against
short circuiting and overloads.
• Compressor heat relay: intervenes in the event
of overloads or operating faults.
• Safety pressure switch: intervenes in the event of
excessive pressure in the refrigerant circuit.
• Plug fuses: intervene in the event of verpressure
or operating fault in the safety pressure switch
(see above).
• Chamber temperature control: operated by the
electronic board by means of a probe inside the
cell.
• Temperature control end defrost cycle:
controlled by the electronic board by means of
the probe in the evaporator.
2.9 Appliance disposal
After the useful life of the applicance has been
realized, be sure to demolish and dispose of the
machine in compliance with the regulations
applied in the country of installation,
particularly in regards to refrigerant gas and
compressor lubricant oil.
