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.  
INSTALLATION AND MAINTENANCE  
The following instructions are addressed to qualified personnel. Repairs should be per-  
formed 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:

INSTALLATION (CONT.)  
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 3-  
wire 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.
