Control unit valve connection
•
System only works if connected to the 3-wire type valves.
• Use ARAG valves: use of unsuitable valves not provided by ARAG automatically voids the warranty.
ARAG is not liable for damage to the equipment, persons or animals caused by failure to observe the above instructions.
• All valve connectors must be provided with seals before being connected (Fig. 10).
• Make sure the seals are correctly fitted to avoid water infiltration when using the control unit.
