Instructions
16 - Warranty
Always transmit the model number and serial number with any claim filed regarding this product.
The product warranty may be void in following cases:
• Absence of nameplate.
• External modifications, in particular, drilling, welding, broken feet and shock marks.
• Compressor opened or returned unsealed.
• Rust, water or leak detection dye inside the compressor.
• Use of a refrigerant or lubricant not approved by Danfoss.
• Any deviation from recommended instructions pertaining to installation, application or maintenance.
• Use in mobile applications.
• Use in explosive atmospheric environment.
• No model and serial number transmitted with the warranty claim.
16.1 Scope not warranted
1. Nonconformity in the selection of model or design of condensing unit. When we judge that the failure has resulted from a fact that the installation
work is made without observing instructions or cautions given in the instruction manual, or the condensing unit that has an excessively larger or
smaller capacity is selected for the cooling load. (Example: Mistake in selection of expansion valve, improper installation, omission of solenoid valve in
liquid line, etc.)
2. Nonconformity in the selection of low pressure device.
• When the low pressure device doesn't meet the requirements described in Page 9.
3. When any items other than the followings specified by us are used.
• Refrigerant R744
• Condensing unit oil "Diamond Freeze MA68"
4. Nonconformity in installation work
• Damage caused by improper handling during installation work
• When it is judged that foreign matters entered in the cycle during installation piping work.
• When it is judged that electric wires have been connected improperly during installation.
• When matters have not been improved although our supervisor warned improper practice during installation.
• Accident resulted from violating relevant laws or regulations.
• When it has been operated neglecting larger vibration or operating noise.
• When the failure was caused by weak foundation or fragile support frame.
5. Accident resulted from modification, incidental work or relocation at site, or overriding protective devices provided on our product.
6. Accident resulted from installing on vehicle, rail car, ship, or other mobile carrier.
7. Accident resulting from nonconformity in operating environment, maintenance and inspection.
• Accidents resulting from installation in the environment impregnated with corrosive gas such as oil (including machine oil), salt (coast area) and
sulphide gas.
• Accident related to installation place (shortage of air blow volume, special environmental conditions like hydraulic pressure, chemicals, etc.)
• Accident caused by maladjustment (overheat degree of expansion valve, pressure switch setting at low pressure side).
• Accident by short-cycle operation (operation and stop of less than 3 minutes each).
• Improper maintenance (clogged gas cooler fins, overlooked inspection and cleaning of fouling, inspection and replacement of dirty condensing unit
oil and gas leak).
• Mistake in repair work (use of wrong parts, missing parts, improper installation).
• Accident caused by overcharge or shortage of refrigerant or condensing unit oil (start failure, poor cooling of motor, improper lubrication).
• Accident owing to insufficient defrosting.
• Accident resulting from abnormal voltage, abnormal electromagnetic radiation, or other external factor like trapped insect.
• When it is judged that air or moisture has been inhaled in the cycle.
8. Accident resulting from running out ranges of evaporation temperature, outdoor temperature, or voltage as specified for this product.
9. Accident caused by external factors such as fire, earthquake, storm or flood, thunderbolt, abnormal weather, other natural disasters, soot, ash, acid
rain, etc.
10. Any other accidents are not warranted at all, including installation or use contradicting common practices in the installation, operation, adjustment
or maintenance of the condensing unit. Also exempted from this warranty are consequential compensations for damage on cooled goods, or
business interruption. It is recommended therefore to install an alarm system, or subscribe to a property insurance through our dealer in preparation
for consequential accidents.
