INSTALLATION
GENERAL
This manual covers the Moyer Diebel 301 undercounter high temperature dishwashing machine
with built-in booster. Liquid detergent and rinse aid dispensing pumps are standard. Even though
chemical dispensing settings are preset at the factory for average water conditions, to ensure
maximum performance and best results, have your chemical supplier perform a water titration
test and adjust dispensing pumps for your specific water conditions.
INST ALLATION AND MAINTENANCE
The following instructions are addressed to qualified personnel. Repairs should be performed by authorized personnel using parts supplied by the manufacturer.
NOTE:
Installation must allow for the ability to remove machine for servicing.
UNPACKING
WARNING:
Care should be taken when lifting the machine to prevent damage.
The machine is normally shipped on a skid enclosed by straps. When transporting the machine,
use a lift truck or fork lift, positioning the box properly on the forks.
1. Immediately after unpacking your machine, inspect for any shipping damages. If damage is
found, save the packing material and contact the carrier immediately.
2. Remove the dishwasher from the skid. Adjust the feet if required, then move the machine to
its permanent location.
3. Level the machine (if required) by placing a level on the top if the machine and adjusting the
feet. Level the machine front-to-back and side-to-side.
4. Remove any foreign material from inside of the machine.
CAUTION:
!
After locating your machine, it must meet with all local health codes. Consult your local
health department representative to ensure compliance.

ELECTRICAL CONNECTIONS
NOTE:
Leave enough electrical cable behind the machine so that the dishwasher can be pulled
forward a minimum of two feet to be serviced.
WARNING:
Electrical and grounding connections must comply with the National Electrical Code and/or
Local Electrical Codes.
WARNING:
When working on the dishwasher, disconnect the electric service and tag it to indicate work
is being done on that circuit.
1. The electrician should compare the electrical specifications on the machine electrical data
plate (located in the control panel) to the electrical power supply before connecting the
machine to the incoming service at a fused disconnect switch.
NOTE:
The 208-240V/60Hz/1PH electrical supply service for this machine must be a 2-wire plus
ground service. For optional 208-240V/60Hz/3PH the electrical supply service must be a 3wire plus ground service.
2. On the 208V-240V models, a knockout is provided at the rear of the junction box for
electrical service connections. A fused disconnect switch or circuit breaker (supplied by
user) is required to protect each power supply circuit.
PLUMBING CONNECTIONS
CAUTION:
!
Plumbing connections must comply with local health and plumbing codes.
Water Connections
1. Connect the hot water supply to the fill hose provided with a 3/4" NPT fitting.
2. Install a manual shut-off valve in the water supply line to accommodate servicing the
machine. The shut-off valve should be the same size or larger than the supply line.
3. Install a 3/4" pressure reducing valve (PRV) (supplied with machine) in the water supply
line, and set at 22PSI/151kPa.
