F.OVERFLOW / VENT CONNECTION IMPORTANCE
Connect a 15 mm (½”) pipe to the overflow/vent connection (½”BSP nipple). This pipe is to be made of a material such that continuous steam will not degrade it (i.e. copper). This pipe must have a continuous fall, not exceeding 3 metres in length and / or contain no more than 4 bends (refer to figure 2).
Figure 1: Water Connection
If the site situation requires a pipe length exceeding 3 metres, then discharge the overflow/drain into a tundish.
The drain pipe work must not exert a pressure of more than 1 metre of head on the Lazer boiling unit (refer to figure 2).
During normal operation of the Lazer, the overflow/vent connection may discharge small quantities of steam and condensate, so it is ESSENTIAL that the drain pipe is attached to the overflow vent connection. This drain pipe must discharge to waste at a point where no scald injury, nuisance nor inconvenience is caused to people in the immediate vicinity.
WARNINGS:
Ensure the overflow/vent line remains open because the Lazer’s tank is not designed to be pressurised. Where freezing may occur, protect the pipes and install an air break. It is recommended to install an air break in the overflow/vent drain line, no more than 300 mm from the Lazer unit. Also it is important to connect the overflow/vent and water inlet correctly. Incorrect connection of pipe work may damage the unit.
G. DRAIN
WARNING:
Before draining the unit, ensure the appliance has been switched off, and water is not hot enough to scald.
