INSTALLATION
PLUMBING
An adhesive backed paper template is shipped with the unit and is used to locate the sink strainer holes. Use the following procedure to install the heater unit to the holding vessel.
NOTE: The FR2 heater should be positioned with
no more than 3' (914 mm) on either side when mounted under holding vessel. See Figure 6. A perforated water baffle (not supplied with unit) must be used to distribute the heated water properly.
NOTE: Use one FR2 for a Hot Food Table
up to 6' (1829 mm) long. Over 6' (1829 mm) minimum 2 units required.
CAUTION
Unit is not weatherproof. For safe and proper operation locate the unit indoors where the ambient air temperature is constant and is a minimum
of 70°F (21°C).
CAUTION
Do not use extension pipes on the inlet and outlet connections on heater units. Poor performance or unsafe conditions may occur.
1.Expose the adhesive back of the paper template and stick the template on the bottom of the holding vessel. Center the template with the words “Front Cover” positioned against the front inside wall
of the vessel.
2.Center punch and drill a 3/4" (19 mm) pilot hole at each of the two center marks on the template.
3.Remove the template and cut a 2" (51 mm) diameter hole at each pilot hole location using a standard #ATV1756 Greenlee cutter.
NOTE: If a #ATV1756 Greenlee cutter is not available, use a standard Greenlee
or ream holes as necessary to 2" (51 mm) diameter required for mounting sink strainers.
4.See Figure 7. In each of the holes, install a male threaded sink strainer with a thin gasket between the strainer flange and the bottom of the holding vessel.
5.Install two thick gaskets at the underside
of the holding vessel along with a thin fiber gasket, and secure finger tight with the nut.
