Delfield SAHRT1-S Operating Guide

Failure to maintain a clean condenser coil can initially cause
high temperatures and excessive run times. Continuous
operation with dirty or clogged condenser coils can result in
compressor failures. Neglecting the condenser coil clean-
ing procedures will void any warranties associated with the
compressor or cost to replace the compressor.

Never use a high-pressure water wash for this cleaning
procedure as water can damage the electrical compo-
nents located near or at the condenser coil.

The heater ducts on heated cabinets are removable for
cleaning. When the ducts are sufficiently cool, remove the
thumbscrews and pull the ducts away from the top of the
cabinet. Reverse this procedure to re-install the ducts.

 Never operate a heated cabinet without all heater ducts
in place!

The interior of heated storage cabinets will be hot for
some time after the power is turned off. Avoid touching
the interior walls and heater ducts with bare hands or
arms until you are certain the unit has cooled. The use
of gloves is recommended.

Gaskets require regular cleaning to prevent mold and
mildew build up and also to keep the elasticity of the
gasket. Gasket cleaning can be done with the use of
warm soapy water. Avoid full strength cleaning products
on gaskets as this can cause them to become brittle and
prevent proper seals. Also, never use sharp tools or
knives to scrape or clean the gasket which could possibly
tear the gasket and rip the bellows.

Gaskets can easily be removed and do not require the
use of tools or authorized service persons.  The gaskets
are "Dart" style and can be pulled out of the groove in the
door and gasket can be "pressed" back into place.

Over time and with heavy use the doors hinges may
become loose. If it is noticed that the door is beginning to
sag, it may become necessary to tighten the screws that
mount the hinge brackets to the frame of the unit. If the
doors are loose or sagging this can cause the hinge to pull
out of the frame which may damage both the doors and

the door hinges. In some cases this can require qualified
service agents or maintenance personnel.

The ERC-2 Electronic Refrigeration Control is a micro-
processor-based electronic controller designed to con-
trol both the temperature and the defrost functions of a
commercial refrigeration unit. Designed for 115 or 208/
240 VAC (50 or 60 Hz), the control comes with four relay
outputs: compressor, defrost, evaporator fan and alarm.

The ERC-2 includes a digital display module that provides
readout of the temperature, time and built-in diagnostics.
The display module can be mounted locally or remotely
from the unit and it contains a touch keypad for simple
programming. For defrost control, it uses a real time clock.

This control is NSF certified and it can be applied to many
different commercial refrigeration applications like reach-
ins, walk-ins, refrigerated cases, or other products where
accurate control of refrigerated space and defrost cycles
is required.

In case of a power failure, the control has a safe operating
mode in case of sensor failure.
