Are there ice-up problems with the release handle of the dual system, with attaching the pin to the pressure hose or with the activation itself ?
No – unless you create an ice-up yourself. However, ensure that the Velcro caps protect the connection to the pressure hose well, no matter whether the release handle is attached, or not. it is also important to treat the trigger handle with care and to avoid any soiling of the pin or its opening. In case of a soiling, avoid cleaning the equipment yourself, replace the handle instead. You could trigger a release which could cause injury. When exchanging cartridges, you will only be charged for a refill. Please also note that the trigger handle must not be attached unless a filled cartridge has been screwed in. Should the system be activated without a cartridge the prick system will be damaged and the whole system may therefore malfunction. If it happened anyway, send the ABS backpack in for a complete check-up.
