New Stainless imp_alt 2/15/05 12:15 PM Page 4 GUIDANCE NOTES TUNDISH DISCHARGE The unit is supplied with two mechanical safety devices. An expansion relief valve, supplied loose, and a temperature/pressure relief valve fitted to the unit, both discharging into a tundish (supplied loose). Discharge pipes must be left open to atmosphere, not blocking the tundish. The responsibility for supplying and fitting the discharge pipe from the tundish is that of the certified installer.

New Stainless imp_alt 2/15/05 12:15 PM Page 7 WORKED EXAMPLE: The example below is for a G1/2 temperature relief valve with a discharge pipe (D2) having 4 No. elbows and length of 7m from the tundish to the point of discharge. From Table 1 • Maximum resistance allowed for a straight length of 22mm copper discharge pipe (D2) from a G1/2 temperature relief valve is 9.0m. • Subtract the resistance for 4 No. 22mm elbows at 0.8m each = 3.2m • Therefore the maximum permitted length equates to 5.8m. • 5.
New Stainless imp_alt 2/15/05 12:15 PM Page 8 ELECTRICAL CONNECTIONS Immersion heaters are rated 3kw at 240v (2.76kw at 230v), incolloy elements, with a thermal energy cutout, and must be connected via double pole switches with a 3mm contact gap separation. Appropriate wiring for the electrical load must be used. The twin immersion heaters supplied with direct units can be switched to utilise low tariff electricity supply. Do not switch on until the unit is full of water.
