GENERAL SAFETY The “Eemax Series Two” heater is specifically designed to take in cold water and heat it to temperatures suitable for normal domestic usage up to a maximum of 140° F (60° C). 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 3/4” NPT pipe connections. Under no circumstances use a blow torch on pipe which is connected to the heater (serious damage to the electronic flow switch will result).

I. MOUNTING THE UNIT 1) The unit should be mounted as close to the point of use as possible. For example, directly beneath the sink is ideal. 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. 2) This unit must only be mounted in a vertical position with the water fittings located at the bottom of the unit.
PAGE 5
II. PLUMBING HOOK-UP 1) The unit is supplied with ¾’’ NPT fittings (Figure 3), 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.

III. ELECTRICAL HOOK-UP WARNING BEFORE BEGINNING ANY WORK ON THE ELECTRICAL INSTALLATION, BE SURE THE SWITCH AT MAIN BREAKER PANEL IS “OFF” TO AVOID ANY DANGER OF ELECTRICAL SHOCK. “Series-two” heaters are manufactured to the following specifications: Figure 4 MODEL TYPE OUTPUT / kW VOLTAGE / V AMPERAGE EX 190 19 *240 2 x 39 Amps EX 144 15 *240 2 x 32 Amps EX 200 20 277 2 x 36 Amps EX 160 16 277 2 x 29 Amps EX1608 16.

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.

“T2” MODELS a) Switch on the power to the first unit, the power indicator light should illuminate. Note: This light should pulse On and Off at first and after about 20- 30 seconds it should stay fully on. b) Switch on the power to the second unit, again the power indicator light should illuminate. Note: This light should pulse On and Off at first and after about 20- 30 seconds it should stay fully on.

TROUBLESHOOTING SYMPTOM “A”: NO HEAT - INDICATOR LIGHT OFF 1) ELECTRIC SUPPLY IS OFF Turn on the main circuit breaker. 2) NO OR LOW WATER FLOW Ensure that the minimum flow rate to switch on your heater is met. T, TC Models – 0.75gpm T2 Models – 1.5gpm Also check that the inlet filter screen is clear from any debris. This is located in the brass inlet boss. 3) WATER CONNECTIONS ARE REVERSED Cold water inlet = right side, hot water outlet = left side.
