3.2 Installation
Many of the problems associated with the degraded perfor-
mance or non-operation of the Tri-Res can be traced directly to
improper installation and/or lack of proper periodic cleaning-all
of which is the responsibility of the customer.
This section is provided to determine that the equipment was
installed correctly, to indicate the proper cleaning techniques
are to be used by groen customers and Tri-Res test procedures.
It is to be expressly noted that ALL work associated with the
installation and cleaning of the Tri-Res is NOT covered by groen
warranty provisions.
3. Water Connection(s)
Install a check valve to prevent back flow in the incoming cold
water line, as required by local plumbing codes. Water pressure
in the line should be between 30 and 60 PSI. If the pressure is
above 60 PSI, a pressure regulator will be needed. These pres-
sures must provide the
1.5 gallons per minute required for
proper unit function.
4. A 3/4 inch female NH connector (garden house type) is
used to attach the water supply to the inlet valve.
Minimum
inside diameter of the water feed line is 1/2 inch. Use a
washer in the hose connection. Do not allow the connection to
leak, no matter how slowly. Do not over-tighten hose connec-
tions.
5. This equipment is to be installed to comply with basic
plumbing code of the Building Officials and Code Administra-
tors International, Inc. (BOCA) and Food Service Sanitation
Manual of the Food and Drug Administration (FDA).
NOTE: Local code may also require check valves in the water
supply line.
ANSI 21.69.CSA 6.16, and a quick-disconnect device that
complies with the standard for quick-disconnect devices for use
with gas fuel, ANSI Z21.41.CSA 6.9
Adequate means must be provided to limit the movement of
the appliance without depending on the connector and the
quick-disconnect device or its associated piping to limit the
appliance movement.
The location where the restraining device may be attached to
the appliance shall be in accordance with groen specifications
for the device.
6. Drain Line Installation
The drain line should not be less than:
1-1/2” – for single units
2” – for double stacked units
There must be a 2” air gap to the (non-pressurized) building
drain. Make sure that the drain is sloped AWAY and DOWN
from the Tri-Res and that there are no obstructions in the line.
Failure to observe these requirements may cause a water trap
in the drain line and produce enough back pressure to prevent
proper cavity draining-resulting in condensate water leaking
from the door. Drain line must
NOT
be made of plastic pipe. It
must be able to withstand boiling water.
Steam Free Zone: The Tri-Res can be damaged by steam from
external sources.
Do not install
the unit over a steam venting
drain. Ensure that steam is not present in an area bounded by
the footprint of the unit and a circle 18 inches in radius about
the right and left rear corner of the unit (see figure below).
