GENERAL The Eemax “Series Six” water heater is specifically designed to take in cold or pre-heated water and heat it to temperatures suitable for emergency equipment, With a maximum output temperature of 140°. To obtain optimum performance and energy savings, the unit should be located as near as possible to the point of use. The unit must only be installed in a vertical position with the inlet and outlet at the bottom.
PAGE 4
MOUNTING THE UNIT 1) The unit should be mounted as close to the point of use as possible. 2) This unit must only be mounted in the vertical position with the water fittings located at the bottom of the unit. Mounting other than in the vertical position WILL cause element burn out. 3) The cold water inlet is on the right hand side and the hot water outlet is on the left hand side. Under NO circumstances can these be reversed. 4) Leave a minimum of 8” above the unit for easy replacement of the elements.

PLUMBING HOOK-UP 1) The unit is supplied with NPT fittings., USE THESE; DO NOT USE PIPE DOPE AND DO NOT SOLDER PIPE TO THE INLET OR OUTLET. 2) Take care to ensure that the pipes are correctly aligned with the inlet and outlet bosses in order to avoid excessive stress on the heater manifold. NOTE: When soldering pipe joints remove heater from the wall. Serious damage can occur if any soldering is done while pipes are connected to the heater.
