Page 6 HYDRIM C51wd Service Guide
2.1 Pre-Installation
The machine must be installed and levelled correctly for the unit to function as described.
All electrical work must be carried out by a qualified electrician and in compliance with all
local and national electrical codes.
The electrical outlet should not be located directly behind the unit. The outlet needs to be
accessible after the unit is installed. The power cord must be routed away from the back
panel and hot water inlet hose.
This appliance must be correctly grounded! The manufacturer cannot be held
responsible for damage or injury caused by incorrect or missing grounding.
• The Hydrim unit is heavy (35 kg). Exercise caution and obtain assistance when
moving it.
• The Hydrim is equipped with an air gap / anti-suction device to prevent backflow of
dirty water into the water supply. No other air gap device is necessary.
• If you need to extend the water inlet and drain hoses,ensure that you use commercial
grade plumbing hose. The maximum length of the drain hose is 3.3 m.
2.2 Tools and Supplies Required to Install the Hydrim
• Slot screwdriver • Channellocks
Ensure that HIP Cleaning Solution (instrument wash chemical) is available. All other
supplies are included with the Hydrim unit.
Voltage: 220 - 240 V
Frequency: 50 Hz
Rated load:2kW
Circuit breaker: 10 A per phase

2.3 Installation Options
Ensure that there is a 75mm space at the top, rear and both sides of the Hydrim. This will
facilitate installation, levelling, service access and air exhaust from the rear of the unit. Do
not locate the electrical outlet directly behind the Hydrim, as this is where warm, moist air
from the chamber is exhausted. Do not move the Hydrim into place by maneuvering the
open wash chamber door. This may cause to door to become misaligned and leak.

2.4 Connecting The Water Inlet Hoses
Connect the hot water hose (red) to
the hot inlet valve on the Hydrim
(indicated by a red dot) and the cold
water hose (blue) to the cold water
inlet valve on the Hydrim (indicated
by a blue dot).
The connector with the elbow
should be attached to the back of
the Hydrim unit.
The washer with the screen goes
to the water supply connector.
Make sure that the inlet valves are
free of debris.

2.5 Drain Requirements
Connect the drain hose to the drain outlet. The drain hose can be attached to existing
drain lines using a 3.5 cm or larger standpipe / P-trap combination. If the hose is
connected directly to the drain line, fittings and adapters should not reduce water flow.
The drain hose should be attached to the main drain at a point no more than 1 metre.
above the base of the Hydrim. A floor drain is acceptable (check local codes).
2.6 Levelling the Hydrim
For the unit to function properly, it will need to
be correctly levelled. To level the unit, follow
these steps:
1. Adjust the legs underneath the unit.
2. Use the levelling bubble on the top right hand
side as a guide.
3. When the bubble is in the centre, the unit is
correctly levelled.
2.7 Installing Cleaning Solution
Ensure that the quick-disconnect cap on the HIP Hydrim Cleaning Solution bottle is tight.
Install the bottle, and loosen the screw cap slightly (see Step 4) to prevent formation of a
vacuum in the bottle.

2.8 Setting the Water Softener (salt):
Hydrim is equipped with a built-in water softening system which needs to be
adjusted according to the local water hardness. The Hydrim water test kit
includes three water hardness test strips in bags. Take a water sample from
the location where the machine will be installed. Open one of the bags and
remove the test strip. Dip the strip in the water. Compare the color of the
strip with the chart on the back of the bag. Determine the water hardness
according to the chart on the water test kit envelope. Power the unit on.
Touch the “i” in the lower right hand corner of the sceen. Select
“Technician”. Enter 7919 and touch EN. Select “Cycle Settings" and then
"Set Regeneration”. Using the up and down arrows, set the water softener
regeneration level according to the following table:
Pour 0.5 litre of water into the water
softener by pouring it into the salt
container and inserting it into the
chamber wall. Add 0.5 kg of water
softening salt in the same manner.
Screw the salt container tightly into
the wall of the chamber.
2.9 Installation Test
Turn on the shut-off valves. Run a test cycle, checking for leaks.
