6) Turn on the main water supply.
7) Purge all air from the water lines and MODEL 1 by
opening a hot water demand source (hot faucet, shower,
etc.) Allow water to run though the water heater for at
least two to three minutes. Water from faucet will not be
hot at this point.
SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF
YOU IGNORE THIS WARNING.
The MODEL 1 Water Heater must be installed by a
licensed electrician in accordance with all applicable
national, state, provincial and local electrical codes.
Under no circumstances should the MODEL 1 Water
Heater be installed without first shutting off all power to
the unit at the fuse or breaker box.
STEPS
1) Prior to wiring your MODEL 1 Water Heater, a licensed
electrician should consult the Electrician’s White Paper
found on page 11.
2) Verify all wiring (wire gauge) and circuit protection
(breakers) comply with national and local electrical
codes.
3) The MODEL 1 requires two power conductors and one
grounding conductor.
The line conductors can both be phase, or one line may
be phase and the other neutral (split-phase installation).
Connect the two power wires and one ground wire to
the MODEL 1.
4) Verify water supply to the MODEL 1 Water Heater is
turned on, and MODEL 1 has been purged of air.
CAUTION: Serious damage to your MODEL 1 Water
Heater can occur if all air is not purged from the water
lines initially, or at any time after installation where air
might have been introduced into your home water
system.
