Preventive maintenance/Maintenance
Consult your local Parker office when using high viscosity oils
(e.g. thick lubricating oils) or when operating in cold start mode.
For optimal operation, a cleanliness rating of 17/15 according
to ISO 4406 ISO is required.
Note! Air in the inlet line could cause problem at start-up, fill
the line with oil.

During operation

Caution Risk of severe burns. The cooling system
could become extremely hot during operation, make
sure that the cooling system is cool before touching.
Note! Use hearing protection when standing in the immediate
vicinity of an operating cooling system for long periods of time.
Caution LOC cooling system must not be run in such
a way that the pump maximum pressure is exceeded,
which could occur if the pump outlet is closed or se-
verely throttled. (See pamphlet for the QPM pump.) This
could damage the pump and cause personal injuries.
The pump has no pressure relief valve as standard. Install a
pressure relief valve if the system is equipped with e.g. a shut-
off valve and/or if the pump is operating in cold start condi-
tions. A pump fitted with internally or externally drained by-pass
valve is available as option.

Preventive maintenance

Preventive maintenance work must be carried out at regular
intervals. Make sure that:
• the cooling system is free from abnormal noise or vibrations
• the cooling system is securely fixed
• the cooling system is clean - debris will reduce the cooling
capacity
• the cooling system is free from damage, and that damaged
components are replaced
• the cooling system is free from leaks
• warning labels are in good condition, replace any damaged/
missing label immediately.
Annually: Check the electrical installation. This may only be
made by a qualified electrician.
In normal operating conditions the pump is maintenance free.
In extreme operating conditions the pump requires inspection,
service or replacement of the pump and/or couplings.
See separate pump manual.
Cleaning
Caution Risk of bodily injury. Prior to cleaning,
disconnect all motor power supplies.
Caution Risk of severe burns. As the cooling system
could become extremely hot during operation, make
sure the system is cool before touching.
Installation and servicing manual
Air Oil Coolers, LOC
Cooling system When cleaning the exterior of the cooling
system, for instance using water, disconnect all power supplies.
Be aware of the electric motor protection standard.
Cooler matrix The air fins of the cooler matrix can be cleaned by
blowing through with compressed air. If necessary, a highpressure
washing system and degreasing agent can be used. When using
a high-pressure washing system point the jet parallel to the air fins.
See Figure 7.
Fan housing Remove the cooler matrix when cleaning the inside
of the fan housing. To clean the inside of the fan housing, use
compressed air. If necessary a degreasing agent can be used.
Blow with compressed air from the electric motor side through the
fan guard.
Pump Parker will not be held responsible for any interference in
the pump such as internal cleaning. If the pump has been run with
contaminated oil, clean it by running it with clean oil.
Filter unit (option) Filter elements cannot be cleaned.

Maintenance

Dismounting Parker will not be held responsible for any con-
sequences after repairs, modifications or alterations made by
the customer.
Caution Risk of severe burns. As the cooling system
could become extremely hot during operation, make
sure that the cooling system is cool before touching.
Caution Risk of bodily injury. Disconnect the motor
power supply prior to maintenance.
Note! Used filter elements should be collected according to
specific industrial waste regulations of each country.
Dismounting the cooler matrix
1. Turn off the system.
2. Disconnect the electric motor power supply.
3. Make sure that the system is de-pressurized.
4. Disconnect the oil inlets and outlets.
5. Disconnect the hydraulic hoses from the cooler matrix.
6. Unscrew the screws with washers fixing the cooler matrix to
the fan housing. See Figure 8.
7. Remove the cooler matrix.
Mounting of the cooler matrix
1. Locate the cooler matrix.
2. Secure the cooler matrix to the fan housing by screws.
See Figure 8.
3. Connect the hydraulic hoses to the cooler matrix.
See Figure 4.
4. Connect the electric motor power supply
5. Proceed to Prior to start-up and At start-up.
