Step 3 – Connecting
a) Plumbing
For exposed plumbing connection, connect the cold water inlet pipe from the
base of the heater directly to the 15mm (1/2”) compression fittings with the nuts
and olives provided.
For concealed plumbing connections, connect the cold water pipe through the
rear of the chassis using a 15mm (1/2”) capillary elbow.
Cold water pipes must be flushed before connection to the inlet. Any clogging
due to sediment or fines will adversely affect the operation of the heater.
The heater must be installed with an isolating valve which allows it to be isolated
from the mains supply for servicing.
Water pressure requirements:
Minimum - 0.07 MPa (0.7 bar) Maximum - 0.7 MPa (7 bar).
Caution: If pressure is likely to exceed 0.7 MPa (7 bar), a pressure limiting valve
must be installed in the cold water supply line. Zip recommends a valve rated at
3.5 bar (0.35 MPa) for this application (Zip part No. AQ3).
b) Venting
A vent at the base of the heater must be plumbed to a safe visible location as,
under certain conditions, it may discharge cold or boiling water and / or steam.
For exposed vent plumbing, connect vent outlet from the base of heater to a
15mm or half inch OD pipe which has a continuous fall, is no more than 3
metres long, has no more than 3 right angle bends, and discharges to a waste
water drain.
For concealed vent plumbing (Fig. a), connect plumbing to the vent outlet from
the heater rear using a capillary elbow protruding 45mm from the wall. The
plumbing must then be directed to a tundish that must be in a visible location
before being plumbed away to waste.
Alternatively attach the tundish to the wall (Fig. b) and plumb away to waste.
c) Electrical
For concealed electrical connection, run the power cable through the rear
access opening of the heater to the terminal block within the heater.
For surface mount installation run the power cable through the cable entry
gland at the bottom of the unit to the terminal block within the heater. Ensure
the cable is firmly secured.
Isolation switches must have a contact separation of at least 3mm in all poles.
Do not turn the power ON
until water flows from the tap.
