Page 15: Hot / Cold Water Coil Connections
MANDÍK CPV Installation, commissioning, and maintenance When a trap is installed outdoors, the piping system must be tempered, i.e. using an electrical heating cable. Proper configuration of trap height per the pressure values is as follows: Fig. 3 Vacuum trap with ball HL136NGG May be used at vacuum up to 2300 Pa. - Page 16 MANDÍK CPV Installation, commissioning, and maintenance blocks of the unit or the heat exchangers. Connections must be executed so that expansion of the piping as a result of temperature changes does not result in excessive loading of the ports. Two wrenches must be used to tighten connections. Thread deformation is a significant risk otherwise! A vent valve, if installed, must be located at the highest point on the hot / cold water supply line.
