Frequently Asked Questions - KFM-SC-50-S Hydra Kool

Why are the doors not closing properly?

Check that the unit is level on the floor. Look for any obstructions preventing the door from sealing. If necessary, remove the doors and inspect the bearings for wear or damage.

What should I do if the interior lights are not working?

First, verify the light switch is in the ON position. Check the light connections for any loose wires. If still not working, consult the maintenance section for bulb replacement instructions.

The case temperature is too warm. What could be the cause?

Check that the air return grille is not obstructed. Avoid air drafts near the case. Ensure the store temperature is within limits (≤75°F/55% RH). Clean the condenser coil if dirty and check that the evaporator is not frozen. Verify the temperature set point.

The compressor will not start. What should I check?

Ensure the disconnect switch is closed and the overload protector has not tripped. Check for low refrigerant charge. A defective relay may also prevent starting. Contact a qualified technician if the issue persists.

Why is the unit making unusual noise?

Common causes include low compressor oil, a fan blade causing vibrations, tube rattling, loose parts, or the case not being level. Inspect and tighten any loose components and ensure the unit is on a level floor.

How often should the condenser coil be cleaned?

The condenser should be cleaned at least once a month. Use a brush or vacuum to remove dust and debris. Always disconnect power before cleaning and remove the frontal panel for access.

How do I perform a manual defrost?

On the control panel, press and hold the DOWN/DEF button for more than 5 seconds to enable/disable a manual defrost. The unit will automatically defrost 3 times per day, but manual defrost can be initiated if needed.

What electrical requirements are needed for installation?

The unit requires a dedicated grounded circuit of 115 V, 60 Hz, single phase. Use a NEMA 5-15P or 5-20P receptacle. Do not remove the grounding prong from the plug.

What are the important installation location guidelines?

Place the unit on a level floor in an indoor environment away from direct sunlight, air drafts, and heat sources. Maintain a clearance of at least 2 3/8 inches from walls if positioned against one. Ensure the air intake in front of the condenser is not obstructed.

What does the 12-month warranty cover?

The warranty covers all parts for 12 months from the invoice date. A new part will be provided free of charge, but the defective part must be returned. The warranty does not cover damage from improper use, lack of maintenance, or unauthorized service work.

2 Getting started with your KFM series

2.1 Location

To your new equipment perform well please respect the following warnings:

This is type 1 equipment, intended to work with 75^ircF / 55% RH .

This equipment is intended for maintaining temperature only.

Be sure products are not ambient temperature (must be cold)

This equipment must be located in an indoor environment.

Check for airdrafts and avoid them.

At movement from ac units shouldn't be directed to the equipment.

The equipment must not be directly or indirectly exposed to the sun.

Check for rejected heat from another refrigeration units and avoid that.

Place the equipment in a levelled floor.

Do not obstruct the air way in front of the condenser.

Make sure there is a drain preparation (remotes and fish display cases only).

Models to be positioned against a wall keep a safe distance of 2 ^3/8 .

After servicing always close the doors.

Make sure you have a suitable electrical installation.

This equipment should be handled by a qualified technician.

2.2 Uncrating

All operations must be done carefully.

All plastic protective films must be removed before using the equipment for the first time.
