GENERAL SAFETY The “Eemax ProAdvantage” heater is specifically designed to take in cold or hot water and heat it up to a maximum of 140F (60C). To obtain optimum performance and energy savings, the unit should be located as near as possible to the point of use. The unit is supplied with a ¾” NPT pipe connection. Under no circumstances use a blow torch on pipes which are connected to or near these heaters. Carefully use Teflon tape where necessary ensuring no debris will enter the unit.

I. MOUNTING THE UNIT 1) The unit should be mounted as close to the point of use as possible. Do not install the heater above a faucet or “point of use” because the siphoning effect may drain the heater which can cause premature element burn out. If the unit must be installed at a higher elevation, you must install spring loaded check valves on both the inlet and outlet of the water heater. 2) This unit must only be mounted in a vertical position with the water fittings positioned at the bottom of the unit.

II. PLUMBING HOOK-UP 1) The unit is supplied with ¾’’ NPT fittings (Fig. 2a), USE THESE. DO NOT USE PIPE DOPE AND DO NOT SOLDER 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 body molding. 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.

IV COMMISSIONING YOUR HEATER IMPORTANT BEFORE SWITCHING “ON” THE POWER AT THE MAIN CIRCUIT BREAKER PANEL MAKE SURE THAT THE HOT WATER CIRCUIT IS FREE OF AIR POCKETS OR ELSE PREMATURE FAILURE OF THE ELEMENT WILL OCCUR. TO DO THIS OPEN ALL HOT WATER OUTLETS ONE AT A TIME FOR A MINUTE OR TWO UNTIL THE WATER FLOW IS CONTINUOUS AND FREE FROM “GULPING” AND FREE FROM VISIBLE AIR POCKETS. 1) Open fully both inlet and outlet valves at the heater. 2) Open any hot water outlet in the system.

TROUBLESHOOTING SYMPTOM “A”: NO HEAT, INDICATOR LIGHT OFF 1) ELECTRIC SUPPLY IS OFF Turn on the TWO main circuit breakers. Ensure the breakers are properly connected to the relay. L1/L2 from one breaker must correspond with the same relay. You must be able to get 240V across each relay when powered up independently. Do not use space saving breakers. 2) NO OR LOW WATER FLOW Ensure that the minimum flow rate to switch on your heater is met. “TC” Models minimum flow rate = 0.70 gallons per minute.
