Compressor Warranty Information and
Suggested Guidelines for Preventive Maintenance
All HANBELL screw compressors are put through strict quality and performance testing prior to shipping from
the factory.
Provided that terms of payment are observed, a two-year (24 month) Manufacturer’s Warranty against factory
defects is offered from the date of installation or 27 months from date of shipment; whichever occurs earlier.
The following procedures and safeguards must be followed for the Warranty to be validated:
• The Warranty Start-up/Status Report Form must be completed and returned for each compressor purchased at the
time of startup.
• An Oil Sample Report must be submitted to and approved by MCS after initial break-in period for each compressor
purchased. Preferably around 72 hours of run time, but no less than 4 hours.
• The compressor must be equipped with an Over/Under Voltage Phase Protection Device.
HANBELL compressors sold by MCS, which are controlled by an MCS micro controller with software and
configuration written and tested by MCS, shall be covered under a three-year (36 months) warranty agreement
on the compressor only.
MCS may, at its option, repair or replace defective items that are under warranty. Repair or replacement
of a warrantied compressor does NOT reset the warranty date; however, the Factory Warranty will
remain in effect for the remaining period of time.
1.1. Maintenance
The technicians should be familiar with the Hanbell compressor before attempting any maintenance on the unit.
Periodical checks and regular maintenance are very important for the long-term and trouble-free compressor
life and for maintaining the warranty. The content here is to help the operator and service people to know how
the regular maintenance can be done and when a suitable time is for each item. Operators and service people
should follow the instructions on these pages when working on the maintenance.
Besides the regular maintenance, Technicians should check the system’s working status by noting down its
working parameters on a set schedule. Most of the time abnormal system conditions can be found via comparing
its working parameters with its daily operating data.
„
Compressor unit should be stopped before doing the maintenance work.
„
Disconnect power from unit before doing the maintenance work.
„
Close all the isolation valves before doing the maintenance work.
„
Wear safety equipment when doing the maintenance work.
„
Ensure adequate ventilation before doing the maintenance work.
„
Take safety precautions for the refrigerant used and work with care.
1.2. Short Term Maintenance
During commissioning period or after a few hundred hours of compressor run time, the following checks and
replacement shall be done in order to protect the compressor and understand the compressor’s working status.
1.2.1 Suction Strainer
The Suction strainer plays a very important role to long-term compressor life. In the initial commissioning, debris
and welding slag might find its way to the compressor’s suction side. With the help of the suction strainer, debris
will be gathered inside the strainer to protect the compressor from rotor damage. Technicians should check the
suction strainer at the end of commissioning and after 200 hours of initial running . Any dirt and unwanted
material should be removed during this check. Wash the strainer basket in solvent and blow clean with air.
