Warning
Ensure that rigging and lifting equipment are of sufficient capacity to
support the weight of the unit.
All assemblies must be secured during lifting and rigging with
temporary supports and restraints of adequate size and strength
according to local codes and ordinances until the equipment is
permanently fixed in place.
All fastening devices must be capable of locking the assembly in
place without loosening or breaking away due to system operation
and vibration.
Nailor tests all risers and coil packages to 400PSI for leaks before
shipping. However, during transit, vibration may cause loosening
of connections. Therefore, all connections must be checked at
time of installation. Any connection found to be loose must be
tightened. Nailor will not be held responsible or accept any charges
for tightening loose fittings. Backup wrenches must be used during
the tightening process.
Should a hose swivel connection be disconnected after it has been
tightened the gasket must be checked to see if it needs replacement
and replaced, if necessary, before the hose is re-attached.
Female swivel fittings with gasket should not be tightened to more
than 30 in-lb of torque.
Unit must be pressure tested before applying water.
Backup wrenches must be used during any tightening process to
keep the copper tube or fitting from being damaged.
Nailor will not accept any responsibility for improper tightening
procedures that damage the connections.
