1. FILTER SYSTEM
NTZ® grants a 3-year limited warranty on the NTZ® filter housing (excluding the accompanying
o-rings) from the date of invoice. In the unlikely event that the purchaser finds a defect, the purchaser
must notify their NTZ® dealer. If the defect is justified, the NTZ® filter housing will be replaced or
repaired free of charge. Any claims to NTZ® filter housings should be addressed directly to your NTZ®
point of contact. A claim should contain a clear description of the findings, including pictures and specifi-
cations of the application, along with a copy of the invoice.
2. EXTENDED OIL LIFE / DRAIN INTERVALS
When properly installed, NTZ® guarantees the effective filtering operation of the NTZ® filter and its
positive effects for the equipment. Extended oil drain intervals are achievable with the proper use of the
NTZ® system. However, the condition of the oil and the oil change intervals are also dependent upon
the original equipment manufacturer, operating conditions, selection of lube/oil, and system type. Due
to conditions out of the control of NTZ®, the length of any extended drain interval is at the discretion of
the customer. The customer should perform regular oil analysis to ensure that the condition of the oil is
within the recommended specifications as set by the original equipment/oil manufacturer. Upon request,
NTZ® can aid in this activity.
3. EQUIPMENT WARRANTY
In the unlikely event of material damage to the equipment, NTZ® warrants the entire cost of repair
under the following conditions (Documentation of which is the full responsibility of the claimant):
• The equipment is well maintained and worked properly at the moment of installation which can be
proven by copies of the maintenance and repair history of the equipment.
• The NTZ filter is installed by a certified mechanic.
• The user must demonstrate the device damage is due to the malfunction of a properly installed
and properly used NTZ® filter system.
• The customer must demonstrate from actual data or from a documented extended drain interval
program (historical data) that the oil or lube fluid in the device was within the proper usage specifi-
cations at time of failure.
4. LIABILITY
The above mentioned warranty and NTZ’s liability does not extend beyond (the consequences of) defects
in the NTZ® filter. Damage as a result of other means or caused by third parties, such as by errors
during installation, by incorrect mounting onto the oil circuit or by mounting devices or hoses are not
covered, neither by this warranty nor by NTZ’s product liability. With regard to mounting pieces supplied
by NTZ® the warranty applicable is the warranty of the suppliers/producers of the mounting pieces
which is passed on by NTZ® to its customers. Liabilities are limited to the amounts mentioned in the
insurance policy for liability risks that NTZ has concluded with N.V. Interpolis. No claim shall exceed Euro
