SEISCO Electrical Installation   

WARNING and DISCLAIMERS

READ ALL of the following before installing any Seisco Water Heater.

Warranties are honored and supported with the following:

• Proof that installation and service has been performed by licensed and qualified personnel.
• Unit has been installed to meet the current National Electric Code, as well as any applicable local plumbing, electrical, heating and air conditioning codes.
• Installation has followed the Seisco guidelines as outlined below.
• There is no soldering of the unit to the water lines.

Parts included:

1. Seisco Water Heater

2. Screws

3. Owner’s Manual and warranty card.

4. Copy of electrical and plumbing installation guides.

• Do not cut through the shipping carton with a sharp instrument.
• Stand unit upright (3/4" pipes up)
• Remove plastic wrap
• Remove front cover
• Look for mounting holes in the metal back plate (thru the rubber feet)
• Hold unit in upright position
• Attach to wall with screws supplied or1/4" lag bolts, minimum of 1-1/2" long
• Optional Items (may be needed, not included as standard)

• Temperature/Pressure Relief Valve
• Drain Pan

WARNING:

• Nipples are designed to turn freely if not secured.
• Always use two wrenches when attaching the water supply.
• Do NOT solder water supply line to unit’s nipples. Heat from soldering MAY damage the heat exchanger, and any soldering will void warranty.
• Hold the unit’s nipple secure while attaching to external piping.
• Do NOT attempt to attach water supply to unit’s "inlet" or "outlet" nipples without securely holding the nipple with a second wrench.

WARNING:

• A temperature and pressure relief valve may be required by local code.
• One of the many safety features in the Seisco Water Heater’s patented control system is the electrical mechanical high limit thermostat.
• The Seisco Water Heater utilizes control logic, as well as electro-mechanical high limit thermostats for over-temperature protection.
• Since the Seisco Water Heater does not utilize a storage stank, the use of a temperature/pressure relief valve is not required by many national standards, including UL STANDARD 499.
• When a temperature/pressure relief valve is installed by a qualified and licensed professional (not provided as standard equipment -- can be purchased as an option), this should be checked carefully after the water supply is turned on.

T and P VALVE CHECK

• With water supply ON, there should be NO WATER FLOWING from the valve.
• Operate the valve manually two or three times to purge trapped air from top of tank.
• Close valve.
• Water should stop flowing COMPLETELY prior to connecting the drain piping to the valve.

DRAIN PAN / SPLASH COVER

If the Seisco Water Heater is installed in an area where water damage can occur to the area adjacent to or below the heater, a drain pan must be installed.

Drain Pan must be ...

• A minimum of 1-1/2" deep
• Piped to a suitable drain
• Must protect an area a minimum of 1-1/2" greater than the lower external dimensions of the Seisco Water Heater
• Splash Cover must extend 1-1/2" greater than the dimensions of the Seisco Water Heater.
