Safety Instructions for the Service at the Single Axis Valve Gate Nozzle 16SVH
Hot Surfaces HazardContact between the skin and hot surfaces could result in burns.Use personal protective equipment, such as gloves, apron, sleeves and face protection, to guard against burns.When servicing or handling the hot runner system outside the manifold plates or the injection molding machine, care must be taken to heed the hot surface exposure warnings.For first aid contact your medical / safety representing.
Hazard of Pressurized AirPressurized air blow can result in hot plastic or foreign bodies entering the eyes, causing vision damage.Following work must be carried out by qualified and experienced persons.Use personal protective equipment: Face protection, hearing protection and gloves.
NOTICEHazard of Material Damage
Without consulting Synventive it is not permitted to do modifications to the hot runner system e.g. geometrical changes to the nozzle tip, except the part shape adjustment in the area of material allowance.Any impact against the nozzle tip may result in its damage.Never hammer or impact the nozzle tip from the front (i.e. from the side of the mold).Twisting could damage the nozzle tip.When replacing the nozzles, the sealing rings must always be replaced.

Mounting the Actuator Housing HYC2314S01 on the Single Axis Valve Gate 16SVH
1) Mount the actuator housing (1, Part of HYC2314S01) with the pistons (2, Part of HYC2314S01) into the related holes of the suspension ring (5, Part of HYC2314S01).
2) Turn the pistons (2, Part of HYC2314S01) to align the holes (a) at the pistons ( 2, Part of HYC2314S01) regarding the holes at the suspension ring (5, Part of HYC2314S01).
3) Take the actuator housing (1, Part of HYC2314S01) away from the suspension ring (5, Part of HYC2314S01).

5) Check the fit of the adjustment bushing HYC2314AB01).
NOTICEThe adjustment bushing HYC2314AB01 has to be positioned 20 mm to the upper edge of the guide sleeve and fixed with the hexagon socket set screw (19).
NOTICEThe inside thread of the suspension ring (HYC2314SR01) is a left-hand thread.
6) Screw the suspension ring (HYC2314SR01) at the adjustment bushing (HYC2314AB01).
NOTICEThe suspension ring (HYC2314SR01) has to be positioned 44 mm to the upper edge of the guide sleeve (N9).

10.3.2.6 Grounding of the Single Axis Valve Gate Nozzle
Danger to Life by Electric ShockThe Single Axis Valve Gate Nozzle has to be properly grounded to prevent serious personal injury or death.Electrical work must be carried out by qualified persons.Verify that all power source connections are properly grounded.In Emergency case - Switch all systems off.For first aid contact your medical / safety representing.
1) Check the position of the cooling bar (6) on the actuator (8).
NOTICEThe cooling bar (6) must be easily movable to be positioned on the actuator (8). If this is not possible, contact Synventive customer service.
2) Tighten the ground wire with a socket cap screw (16) on the cooling bar (6).
