Ice rink installation and commissioning with defined acceptance criteria

Installation is the point where drawings, equipment and site conditions become one operating system. A rink should not be considered complete simply because the mats are connected or the chiller starts. Refrigeration, hydraulics, boards, controls, electrical supply, ice build-up and operator workflow must all be checked under real operating conditions.

SPORTWAVE coordinates installation and commissioning in Lithuania and Latvia with one local technical lead and, for AST-based projects, direct technical coordination with AST where required.

Commissioning starts before equipment arrives

Many installation delays are caused by incomplete site preparation rather than by the rink equipment itself. Before delivery, the project should confirm that the site is ready for the agreed system.

Typical pre-installation checks include:

• base dimensions, level and surface condition;
• structural readiness and floor construction;
• electrical supply, protection and connection point;
• water supply and drainage;
• refrigeration-plant position and service clearances;
• airflow around air-cooled equipment;
• pipe and cable routes;
• board fixing conditions;
• access for trucks, lifting and handling equipment;
• temporary barriers and safe work zones;
• coordination with other contractors still working on site.

Resolving these items before delivery protects the installation schedule and reduces improvised changes on site.

Different rink technologies require different installation sequences

The detailed method depends on whether the project uses mobile EPDM mats, IceBox, SkateWay®, IcePhalt®, a concrete-integrated floor or synthetic panels.

A mobile EPDM installation typically involves:

1. base inspection and preparation;
2. collector / IceBox positioning;
3. mat deployment and alignment;
4. hydraulic connections;
5. connecting pipework to the refrigeration plant;
6. filling, venting and pressure checks;
7. refrigeration start-up;
8. board installation;
9. controlled ice build-up;
10. final operational checks and handover.

Permanent systems require additional coordination with structural, slab, insulation and building-service works before the refrigeration circuit becomes inaccessible.

Pressure integrity must be verified before freezing begins

Leaks that are easy to repair during installation can become extremely difficult once the rink is covered with ice or embedded in a permanent floor.

The hydraulic circuit should therefore be pressure-tested and inspected according to the system design and manufacturer requirements before normal operation begins.

SPORTWAVE verifies connections, manifolds, accessible joints and the refrigeration / secondary-fluid interfaces before the system is accepted for ice build-up.

Filling and venting are part of hydraulic commissioning

A secondary circuit cannot perform correctly if air remains trapped in the mats, headers or high points.

Commissioning should confirm:

• correct secondary-fluid mixture and concentration;
• complete filling of the circuit;
• effective venting;
• stable expansion volume;
• pump suction conditions;
• absence of abnormal cavitation or noise;
• correct flow direction.

For mobile systems, these steps are especially important after every seasonal reinstallation.

Flow balance is checked before blaming the chiller

A refrigeration unit can have sufficient nominal capacity while parts of the ice remain warmer because the coolant is not distributed evenly.

Commissioning therefore checks hydraulic behaviour across the rink, including:

• pump operation;
• supply and return temperatures;
• pressure loss;
• manifold balance;
• flow through different rink zones;
• valve position;
• behaviour at full and part load where applicable.

For custom Ice Worlds and SkateWays, branch lengths and connected zones require particular attention because the geometry is less uniform than a standard rectangle.

Temperature mapping confirms whether the rink is behaving uniformly

Before opening, the system should demonstrate that cooling is reaching the full rink area consistently.

Temperature checks can identify:

• warm corners;
• poorly supplied hydraulic branches;
• local insulation or base problems;
• sensor positions that do not represent the actual ice condition;
• sections affected by solar radiation or building heat gains.

The objective is not one perfect number at one sensor. It is stable and predictable behaviour across the usable surface.

Refrigeration commissioning is more than pressing START

The plant should be checked against the design operating condition and control philosophy.

Depending on the system, commissioning can include:

• compressor and chiller operation;
• pump sequence;
• secondary-fluid supply and return temperatures;
• pressure and temperature limits;
• condenser / dry-cooler operation;
• fans and airflow;
• staging or capacity control;
• setpoints;
• safety trips;
• alarm communication;
• remote monitoring where included.

Any commissioning setpoint should reflect the intended rink use rather than an unnecessarily cold generic default.

Controls and alarms need a functional test

An alarm that appears on a screen but never reaches the responsible person is not a complete alarm system.

Before handover, the project should verify:

• sensor readings are plausible;
• control modes operate as intended;
• scheduled operation works;
• high / low limits respond correctly;
• fault notifications reach the correct contact;
• remote access works where provided;
• operators know which alarms require immediate action.

Board installation is checked as a safety system

Boards are not decorative finishing items. Before public use, the system should be inspected for alignment, secure connections, gate operation and required spectator protection.

Checks may include:

• board geometry and corner radii;
• fixing and support;
• gate latches;
• player / penalty boxes where relevant;
• glass and netting;
• resurfacer service gate;
• thresholds and transitions;
• sharp edges or protrusions;
• advertising panels and rear cladding.

Resurfacer access is tested before opening

The selected machine must pass through the service gate, turn safely and reach its filling, dumping and storage areas.

This should be physically checked during commissioning rather than assumed from dimensions alone. The route should not conflict with public circulation or emergency access.

Ice build-up is a controlled commissioning phase

Real ice should be built progressively rather than by applying a large amount of water at once.

AST’s rental documentation explicitly describes qualitative ice build-up using a spray / fine-layer method rather than flooding the rink in one operation. Thin controlled layers improve bonding and allow the refrigeration system to remove heat progressively.

The build-up process also gives the commissioning team time to observe:

• surface temperature;
• uniform freezing;
• local high and low points;
• hydraulic behaviour under increasing load;
• board / ice interfaces;
• drainage and surrounding site behaviour.

Ice thickness is established deliberately

IIHF guidance recommends approximately 25–35 mm ice thickness for normal arena operation. The initial build should therefore target the required operational thickness rather than creating an unnecessarily thick sheet for perceived safety.

Thicker ice adds thermal resistance and increases refrigeration energy. Thickness measurement should be included in the handover routine so operators can prevent gradual accumulation during the season.

Initial resurfacing proves the operating workflow

Before the venue opens, the operator should complete the resurfacing route on the actual ice.

This verifies:

• gate width;
• turning space;
• machine traction;
• snow-dump route;
• water-filling point;
• edge-maintenance requirement;
• time needed for one complete cycle.

If the operational route does not work during commissioning, it will not improve when the rink is full of visitors.

Commissioning should verify interfaces between contractors

Many failures occur at the boundary between packages:

• electrical supply is technically present but undersized;
• drainage exists but not where the operator needs it;
• the chiller is installed but airflow is blocked;
• the board gate is installed but the resurfacer cannot turn;
• the building HVAC system adds excessive heat or humidity to the ice;
• remote monitoring exists but network access is not available.

SPORTWAVE’s role as local technical coordinator is to identify these interfaces before they become operating failures.

Temporary and permanent projects have different acceptance priorities

Operator handover is part of commissioning

A functioning system is not fully commissioned until the people operating it understand the normal condition and the first response to abnormal behaviour.

Handover can include:

• normal start / stop procedure;
• ice-temperature targets;
• control modes;
• daily visual and temperature checks;
• resurfacing routine;
• ice-thickness checks;
• pump and chiller status;
• alarm response;
• board and gate inspection;
• when to contact SPORTWAVE technical support.

Document the baseline while the system is new

Commissioning data create the reference for future service. Useful baseline information can include:

• supply and return temperatures;
• pump and flow settings;
• normal pressure readings;
• ice-temperature map;
• control setpoints;
• alarm settings;
• electrical load where measured;
• initial ice thickness;
• photos of equipment and valve positions;
• serial numbers and equipment records.

If performance changes months later, this baseline helps distinguish normal variation from a real technical drift.

Acceptance should close with a punch list

Any remaining minor items should be recorded rather than left as informal promises. A commissioning punch list can identify incomplete labels, insulation, documentation, spare parts, cosmetic defects or final adjustments together with responsibility for close-out.

This creates a clear transition from construction into normal operation.

Installation is not the end of technical responsibility

After commissioning, the project enters the lifecycle phase. SPORTWAVE remains available for diagnostics, warranty response, preventive maintenance, spare parts, operator support and future optimisation.

For seasonal systems, observations from dismantling should be recorded so that the next installation can be faster and better prepared.

What we need before installation begins

• approved technical scope and rink layout;
• confirmed site readiness date;
• base / structural completion;
• electrical connection details;
• water and drainage availability;
• refrigeration-plant and pipe-route approval;
• board layout and gate positions;
• resurfacing-equipment information;
• site access and lifting plan;
• responsible contacts for local electrical, structural and building-services works;
• target ice opening / first training date;
• operator contact for handover and training.

With these interfaces confirmed, SPORTWAVE can coordinate installation, system checks, ice build-up and handover against a clear commissioning sequence rather than relying on an undefined “start-up” at the end of construction.
