GENERAL SAFETY The PS19T and PS28T heaters are designed to take in cold water a nd heat it to temperatures suitable for normal domestic usage up to a maximum of 140 F(60 C). These models are not designed to be used as a sanitary booster which requires operating temperatures above 140 F(60 C) or for any recirculating type applications. To obtain optimum performance and energy savings, these units should be located as near as possible to the point of use.

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 6
II. PLUMBING HOOK-UP 1) The unit is supplied with compression fittings (Figure 1), USE THESE. DO NOT USE TAPERED THREADED PIPE FITTINGS AND DO NOT SOLDER TO THE INLET OR OUTLET. DO NOT USE ANY PIPE DOPE OR TEFLON TAPE WITH THESE COMPRESSION FITTINGS. 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.

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. MODEL TYPE OUTPUT / kW VOLTAGE / V AMPERAGE PS19T 19 *240 2 X 40 PS28T 28 *240 3 X 40 * Units rated of 240 V can operate at 220 V or 208V with reduced output. The output will vary in accordance with the following ratios: volts output ratio 208 volts 220 volts .75 .84 240 volts 1.

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 fully the greatest hot water flowing outlet in the syste m.

If a lower temperature is required for the PS19T, turn the temperature adjustment screw counter-clockwise about 1/8 of a turn (See pages 3 & 4 for adjustment location). Wait 15-20 seconds and check the temperature at the fixture. Repeat this process until the desired temperature has been achieved. For PS28T model try to adjust the 2 temperature adjustment screws by about the same amount so that the lights pulse at the same rate.

TROUBLESHOOTING SYMPTOM: NO HEAT INDICATOR LIGHT OFF Solution 1) ELECTRIC SUPPLY IS OFF Turn on the main circuit breaker. NOTE: If unit has been out of operation, first make sure that the hot water circuit is free of all air pockets or else premature failure of the element will occur. Solution 2) INSUFFICIENT WATER FLOW Insure that the minimum flow rate of 0.8 gpm to switch on your heater is met. 0.8 gpm is equivalent to filling a quart container in 18 seconds.
