Safety Considerations - Carrier 38XTZ 007-024 Installation, Operation And Maintenance Instructions

PRELIMINARY CHECKS
Check equipment received
Carry out an external check to ensure that the units have not
been damaged during transport.
If there are any signs of damage or oil, contact the shipping
company before installing the units. Send the claim documents
directly to the shipping company, stating clearly what has been
damaged. Carrier is not responsible for damage sustained
during shipment, handling and storage.
Check the contents correspond to those listed on the delivery
note. Inform your nearest Carrier office if anything is missing.
To prevent loss or damage, do not remove the original
packaging until the unit has reached the final installation site,
where the installation must be carried out by qualified
personnel.
ATTENTION: Ensure that the unit power supply complies
with the power supply at the installation site.

SAFETY CONSIDERATIONS

Installation and servicing of air conditioning equipment can be
hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install,
start-up or service air conditioning equipment. Untrained
personnel can perform the basic maintenance functions of
cleaning and replacing filters.
All other operations should be performed by trained service
personnel.
When working on air conditioning equipment, observe
precautions in the literature, tags and labels attached to the unit
and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves.
Use a quenching cloth for unbrazing operations.
When handling or charging refrigerant, evacuating the
refrigerant circuit, carrying out leak test, etc., ensure that
adequate precautions are taken.
ATTENTION - VERY IMPORTANT
- To prevent electrical shock or equipment damage, make
sure disconnects are open before electrical connections
are made. If this action is not taken, personal injury may
occur.
- Before performing service or maintenance operations on
the unit, turn off the main power switch to the outdoor
unit 38XTZ. Electrical shock could cause personal injury.
- During unit operation, some of the refrigerant circuit
elements could reach a temperature in excess of 90
only trained or qualified personnel should access areas
protected by access panels.
- The 40ABZ/ALZ units are designed for ducted installa-
tion (indoor air discharge). If ducts are not used the
installer must place a protection grille in the discharge.
- Moving, lifting, transporting and positioning the units
must be done with all outside panels installed.
- Move and position the units with care.
- Do not start up the units until all electrical and
refrigerant connections have been made and the system
has been charged with the necessary oil and refrigerant
quantity.
- Ensure that the equipment used to move the units is
appropriate for the unit weight.
- The location or base on which the 38XTZ outdoor units
are installed must be able to support the operating
weight of these units.
The system used to fix or support the 40ABZ/ALZ
indoor units must also be able to support their weight.
- The units are supplied with a dry nitrogen holding
charge which must be removed before making the
refrigerant line connections and charging the units.
- The 38XTZ and 40ABZ/ALZ units should not be
installed in an explosive atmosphere.
- The unit can operate in normal radioelectric atmospheres
in residential, commercial and light industrial
installations.
For other applications check the electromagnetic
radiation around the units. The units are tested in
accordance with applicable standards on electromagnetic
compatibility.
- DO NOT CONNECT R-22 UNITS TO UNITS FOR R-
407C, E.G. DO NOT CONNECT A 38XT OUTDOOR
UNIT WITH A 40ABZ/ALZ INDOOR UNIT OR A
38XTZ WITH A 40AB/AL.
