6. Installation
6.1 Handling
The frame can be lifted with a crane, holding it by the
lifting points previously explained. Refer to paragraph 1
for further information.
6.2 Hydraulic Oil Requirements
Use of Enerpac HF Series ISO 32 hydraulic oil is
recommended. Enerpac HF oil is available at your local
Enerpac Distributor or Authorized Service Center.
NOTICE
• Failure to use the correct oil type (high-quality ISO 32
hydraulic oil) may result in damage to cylinder hydraulic
components and will void the product warranty.
• Be sure that the oil is clean. The oil cleanliness should
be maintained to a maximum level of 18/16/13 per the
ISO4406 standard. If the oil develops a milky, cloudy
or dark appearance, it should be changed immediately.
• To avoid overfilling and possible equipment damage,
add oil to the pump reservoir only after all Synchoists are
completely retracted and system pressure is released.
• When using a hand-operated pump to power the
cylinder(s), it is permissible to use a high-quality brand
of ISO 15 hydraulic oil. The lower oil viscosity will result
in reduced pumping effort, especially in cold weather
conditions.
6.3 Hydraulic Connections
CAUTION
On double-acting cylinders be certain that hoses
are connected to BOTH couplers. Never attempt to
pressurize a double-acting cylinder if only one hose
is connected.
For installation of Synchoist cylinders, it is not necessary
to start-up the power pack.
It is advisable to connect the hoses with retracted and
horizontal positioned cylinders. If hoses are connected
with cylinders in the vertical position it may be impossible
to connect the hose in the small chamber due to the
pressure created by plunger weight.
Connect hydraulic hoses as follows:
• A Port is connected to the retract outlet of the HPU.
• B Port is connected to the advance outlet of the
HPU.
Figure 9: Distribution manifold ports
Perform the following steps to correctly connect the
hoses:
1. Keep cylinders connected to a hydraulic system
with a fluid cleanliness level minimum of NAS 1638
Class 6.
2. Remove dust covers/rubber plugs from oil ports
3. Inspect all threads and fittings in search of wear or
damage signs and replace as needed.
4. Clean all threads and fittings.
5. Make hydraulic connections for double-acting
cylinders using two hoses.
6. Fully hand-tighten all couplers. Loose coupler
connections will block the flow of oil between the
pump and the cylinder.
Check for leaks in system and have repaired by qualified
personnel.
